Recurrent miscarriage, which is defined as 3 or more miscarriages, affects 1% of reproductive aged females. The internet is a huge resource for snake oil salesman hoping to take advantage of these couples with useless, expensive and sometimes dangerous treatments for presumed problems.

Problems With D&C For Evaluation Of Miscarriage

Chromosomal abnormalities in the embryo are the main cause of early pregnancy losses . It is extremely important to identify these abnormalities, particularly among couples with recurrent miscarriage. The traditional means for evaluating fetal tissue for chromosome abnormality is with a procedure called dilation and curretage or D&C.

Fetoscopy

During a D&C, a woman is given anesthesia in a hospital or surgical center. While laying on her back, the legs are placed in stirrups and a speculum is placed in the vagina. The cervix is grasped and the opening (the cervical canal) is dilated using metal rods of increasing diameter. Once the cervical canal has been opened sufficiently, a long plastic tube attached to a suction machine is placed into the uterus. The suction machine is turned on and the contents of the uterus are aspirated. The tissue obtained has traditionally been sent to a lab that specializes in growing cells and extracting and identifying the chromosomes. Depending on a number of factors, this method took a few to several weeks to grow the cells obtained.

One of the problems with D&C is that when the tissue is aspirated from the uterus, it contains a mixture of cells. There are cells from the fetus itself, cells of the placenta and gestational sac and cells from the mother’s uterine lining. The mother’s cells are typically healthy and grow well whereas the fetal cells can often be barely viable.

In the past, when the genetics lab grows the cells from a D&C, there was no way to ensure that only the fetal cells grew. Consequently, the results of a chromosome analysis often reflected the mother’s chromosomes and not that of the fetus.

In general, the results of a chromosome analysis from a D&C returned one of four results:

  1. The cells did not grow and no chromosome result could be obtained
  2. A normal female
  3. A normal male
  4. A fetus with a chromosome abnormality either male or female

If the cells did not grow, there was no result and no helpful information was obtained. A normal male is a helpful answer. It indicated that it was not the mother’s cells that were analyzed. It also showed that the miscarriage was not due to chromosome abnormality. Other causes for miscarriage must be investigated even if this was the only miscarriage the couple has had. A fetus with a chromosome abnormality is also a helpful result. It reveals the cause of the miscarriage. No further evaluation is necessary. The couple may consider IVF with PGD for their next pregnancy attempt. PGD is the only method available to reduce the chances for a miscarriage due to chromosome abnormality.

A chromosome result indicating a normal female is not a helpful result. It cannot be determined if this came from the fetal cells, as desired, or the mother’s cells. Unfortunately, a large number of chromosome analyses from miscarriages return a result showing a normal female. Studies have shown that 30-80% of the results obtained from a D&C may come from the mother’s cells. Until recently, there was nothing that could be done about this.

Embryoscopy For Evaluation Of The Cause Of Miscarriage

Gestational sac

Recently, a new technique has been used by a few highly skilled physicians. This new technique uses fiber optics to look inside the uterus (hysteroscopy) and has been called embryoscopy or fetoscopy. Like a D&C, a hysteroscopy is usually performed in a hospital or surgical center under anesthesia. The cervix is dilated large enough to allow passage of a fiber optic telescope. Salt water (saline) is used under high pressure to hold the uterine cavity open to allow adequate visualization.

With direct visualization, the implantation site of the pregnancy can be located in the uterus. The fetus grows inside of a spherical structure called the gestational sac. The sac can be opened and the placental tissue and sometimes the fetus can be identified inside.

The hysteroscope has multiple channels. These channels allow for the insertion and removal of fluid to keep the uterine cavity clear to the observer. Another channel transmits the optics and yet another provides the light. A final channel allows for the passage of instruments into the uterus. Using grasping instruments, the placental tissue or fetus can be removed.

Placenta (Chorionic villi)

This is a great advantage over the D&C because the tissue removed is essentially “pure”. That is, only the tissue of interest is obtained. There is little or no chance for the mother’s uterine cells to “contaminate” the specimen. Thus, when a result indicating a normal female is obtained, it can be relied upon as easily as when a normal male result is returned.

There are several benefits of the hysteroscopy approach for the evaluation of the causes for miscarriage. In some cases, when a fetus is present, abnormalities in the development of the fetus can be seen. Collecting the fetal tissue in this way, the specimen is kept sterile and so the chances for the cells to be grown by the genetics lab is enhanced. As stated above, the mixing of the mother’s cells with the fetal cells does not occur, so there is much better reliability.

Another advantage occurs when there is loss of a twin pregnancy. During a D&C, the tissue from both twins gets mixed together. A result may indicate one, both or neither of the fetuses. With the hysteroscopy method, each fetus and its respective placenta can be removed separately.

A recent study compared the results obtained with D&C with that obtained using the the embryoscopy technique. The researchers found that overall, chromosome abnormalities were responsible for miscarriage in 67% of the cases studied. In a significant number of cases, the D&C technique would have provided an incorrect result. This occurred when the D&C result indicated a “normal female” where in reality, the fetus was abnormal.

Microarray For Chromosome Analysis

Recently, a new technology has become available to evalute the chromsomes called microarray. Microarray has several advantages over the older method of cell culture.

  • It is not necessary to grow the cells for several weeks in the laboratory
  • This dramatically reduces the chance of getting “no result”
  • Results are available in 7-10 days instead of 4-6 weeks
  • Sophisticated software algorithms can determine if contamination by the mother’s uterine cells have occurred
  • It is possible to get results even on non-viable cells

Who Is A Candidate For Embryoscopy?

Any woman who has been diagnosed with a non viable pregnancy and who wants to try to determine the cause for the miscarriage can have embryoscopy performed instead of a D&C. Women for whom this is especially important are:

  • Women who have a history of recurrent miscarriage
  • Women who have lost a pregnancy after a heartbeat was seen on ultrasound
  • Women who were receiving treatment  to prevent miscarriage but were diagnosed with a non-viable pregnancy

If I Am Not Currently A Patient Of IVF1, How Do I Arrange To Have An Embryoscopy With Dr. Morris?

If you have had a pregnancy ultrasound which previously showed a fetus with a heart beat but a subsequent ultrasound showed that the fetal heart is no longer beating, then call our office immediately. You will need to do several things fairly quickly.

  • Call our office and state you have a nonviable pregnancy and would like to arrange for an embryoscopy
  • Email of fax a copy of your medical records for this pregnancy, including ultrasound results
  • You will need to electronically complete your medical history online through our patient portal
  • Schedule an appointment in our office for an ultrasound followed by a brief consultation with Dr. Morris

Due to the need to perform embryoscopy rapidly, we may not have time to verify insurance coverage. In this situation, you will be asked to pay for the procedure in advance. Our billing office will work with you to help maximize the chances for insurance coverage. Ultimately, you are responsible for all charges. Please contact our billing office for more details.

What Can I Expect On The Day Of The Embryoscopy?

After being admitted to the hospital or surgery center, you will be seen by the anesthesiologist. He or she will review your medical history and discuss the type of anesthesia that is appropriate for you. You will have an intravenous line placed in your arm.   In the operating suite, you will be anesthetized for the duration of the procedure.

The embryoscopy typically takes about an hour to perform. After the procedure is over, you will be taken to the recovery area. Normally, it will take about an hour for you to wake up completely. You will be allowed to go home after the nursing staff verifies you are stable and you can demonstrate that you can tolerate something to eat or drink and can go to the bathroom.

For the remainder of the day, you should plan to rest at home. You will need a responsible adult to bring you to the surgery center and bring you home again afterward. You cannot drive or operate machinery for twenty four hours. It is likely you will have some cramping and vaginal bleeding after the procedure.

Normally, over the counter medications such as Motrin or Advil will be sufficient to control any discomfort. We will provide you with a prescription for pain medicine in case you need something more.

One week after the procedure, you will need to be seen in the office to review the procedure and make sure you are not having any problems post operatively. It is recommended that you have blood tests to determine your hCG levels every week or two until it has returned to negative. This may be done at IVF1 or with your regular OB Gyn.  

Once the chromosome results are available (usually about 4-6 weeks later), you will be notified by phone or through the patient portal. If you wish, you may consult in the office and discuss the results and / or further treatment options.  

Vagifem® (estradiol vaginal tablets)

What is Vagifem? (estradiol vaginal tablets)?

Occasionally, during infertility treatments, we may tell you that the uterine lining is thin based on ultrasound measurements. There is some evidence, though it is far from conclusive, that a thin lining may be associated with a lower chance for pregnancy in that month. We may, therefore, recommend using estrogen supplementation to improve the thickness. Since vaginal medications have a much better effect than those administered elsewhere, we use VAGIFEM? (estradiol vaginal tablets) for this purpose. Estradiol, is the bio-identical hormone to that that produced by the ovaries during development of the egg.

How Do I Use Vagifem? (estradiol vaginal tablets)?

Tear off a single applicator.

Separate the plastic wrap and remove the applicator from the plastic wrap.

First select the best position for vaginal insertion of VAGIFEM? (estradiol vaginal tablets) that is most comfortable for you.

One method is to recline on your back

alt

Another option is stand.

alt

The applicator should be held so that the finger of one hand can press the applicator plunger. The other hand should be used to guide the applicator gently and comfortably through the vaginal opening.If the tablet has come out of the applicator prior to insertion, do not attempt to replace it. Use a fresh tablet-filled applicator.

crinone

The applicator should be inserted (without forcing) as far as comfortably possible, or until half of the applicator is inside your vagina, whichever is less.

Once the tablet-filled applicator has been inserted, gently press the plunger until a click is heard and the plunger is fully depressed. This will eject the tablet inside your vagina where it will dissolve slowly over several hours.

After depressing the plunger, gently remove the applicator and dispose of it the same way you
would a plastic tampon applicator. The applicator is of no further use and should be discarded properly.

In most cases, our patients will be using vagifem twice daily. Insertion should be done upon waking in the morning and again in the evening before bed.

Treatment of Insulin Resistance in PCOS

Metformin

Metformin for the treatment of PCOS

Metformin is the generic name for a medication which reduces insulin resistance. It is also known as Glucophage, Riomet or Fortamet. Metformin is used as a fertility treatment to cause ovulation in women with insulin resistance or PCOS.

Alternatives to glucophage for treating insulin resistance in PCOS

For women with polycystic ovary syndrome – PCOS, insulin resistance is a common finding. In addition, many of these women do not respond to Clomid (Clomiphene Serophene) (Clomid resistance). For these reasons, many women are now treated with a diabetes medication known as glucophage (metformin) which works, in part, to reduce insulin resistance and improves the chances for ovulating spontaneously or with Clomid. However, many women will have side effects from glucophage such as bloating, cramping, diarrhea, flatulence and nausea. The most serious complication of glucophage is lactic acidosis which is a rare but potentially life threatening condition.

Sitagliptin (Januvia)

Incretins are naturally occurring hormones secreted from the intestines in response to food intake. In the pancreas, incretin hormones act to increase insulin secretion in response to rising sugar levels in the blood. This helps to ensure an appropriate insulin response following ingestion of a meal.

Sitagliptin prolongs the action of incretin hormones by prohibiting their degradation through inhibition of the dipeptidyl peptidase-4 enzyme (DPP4).

A 12 week study of obese women with PCOS who were unable to tolerate metformin were treated with sitagliptin. Sitagliptin was found to improve insulin resistance. another study found that the chance for ovulation was similar to metformin. sitagliptin, however, was tolerated much better than metformin was.

Sitagliptin has been rated by the FDA as belonging to pregnancy category B. Reproduction studies have been performed in rats and rabbits. Doses of sitagliptin up to 12 time the maximum recommended human dose did not impair fertility or harm the fetus. There are, however, no adequate and well-controlled studies in pregnant women. Sitagliptin administered to pregnant female rats and rabbits from gestation day 6 to 20 (organogenesis) did not produce birth defects at approximately 30- and 20-times the maximum recommended human dose. Higher doses increased the incidence of rib malformations in offspring at approximately 100 times human exposure at the MRHD.

Byetta (Exenatide for injection)

Byetta belongs to a class of medications known as incretin mimetics. The incretin hormone which scientists have studied the most is called glucagon-like peptide-1 (GLP-1). Byetta works by mimicking the effects of GLP-1. Studies show it increases insulin sensitivity.

Byetta is approved by the FDA for the treatment of diabetes – not PCOS yet. Two advantages of Byetta that have been shown in clinical studies include better control of blood sugar levels in diabetics and weight loss. Since Byetta improves insulin resistance, some scientists feel that PCOS patients may benefit from taking Byetta.

In a study of 60 overweight women with PCOS, Byetta improved the likelihood of women having regular menstrual cycles. The combination of Byetta with metformin was found to be better than either metformin or Byetta alone. Byetta alone showed improvement in several parameters such as weight, BMI, insulin resistance and androgen levels. Byetta in combination with metformin improved these parameters to a greater extent then Byetta alone.

It is clear, therefore, that Byetta exerts a positive impact on PCOS patients and that combining Byetta with metformin works better than either medication alone.

Byetta has been rated by the FDA as belonging to pregnancy category C. Byetta has been shown to cause reduced fetal and neonatal growth and skeletal effects in mice.  Byetta has also been shown to cause skeletal effects in rabbits. There are no adequate and well-controlled studies in pregnant women. Byetta should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

The most common adverse events associated with Byetta were nausea, vomiting, diarrhea, feeling jittery, dizziness, headache, and dyspepsia. In October of 2007, the FDA reported that it had received 30 reports of patients taking Byetta developing a serious condition known as pancreatitis. Five patients developed serious complications from the pancreatitis such as kidney failure. Although most patients improved after they stopped taking Byetta, eight out of the thirty patients did not improve.

Since those initial reports, there have been several studies trying to determine if there is a relationship between Byetta and pancreatitis. The results have been mixed, some studies showed an increased risk, some did not. Complicating the matter is the fact that type 2 diabetics have a higher rate of pancreatitis even without the use of Byetta. As of late 2011, there were no reports of PCOS patients taking Byetta developing pancreatitis.

At this time, Byetta cannot be recommended as a first-line treatment for PCOS. It may be considered as an alternative, however, with proper counseling.

Glycosidase Inhibitors for PCOS Treatment

Precose (Acarbose)

50-100 mg and are taken with meals

Miglitol (Glyset)

50-100 mg and are taken with meals

Acarbose is another medication used to treat diabetes. Acarbose is an alpha-Glycosidase inhibitor. It works by reducing the absorption of monosaccharides (simple sugars) through intestines and minimize the increase in blood sugar and insulin seen after meals. Serious side-effects of acarbose are rare and although it shares many of the gastrointestinal side effects as glucophage (abdominal distension, diarrhea and flatulence), lactic acidosis is not a problem with this drug. side effects may lessen over time.

Some studies have demonstrated that these medications are capable of lowering the androgen levels in women with PCOS.

In a recent study, researchers looked at 30 women with polycystic ovary syndrome – PCOS who did not previously respond to Clomid . The women were divided into two groups. One group received acarbose and Clomid. The other group received glucophage and clomid.

By the end of three months, the women taking acarbose lost more weight than the glucophage group. Both groups showed a similar improvement in the number of women who ovulated. There were 15 women in each in group and they were studies for three months so there was a possibility of 45 ovulatory cycles (15 x 3). The acarbose group had 20 ovulations and the glucophage group had 24 ovulations. The incidence of side effects was the same in both groups and there were no serious adverse effects in either group.

In summary, it seems that acarbose could provide a reasonable alternative to glucophage for treating insulin resistance in polycystic ovary syndrome – PCOS patients, though the expected benefits are minimal. This was a small study so there isn’t nearly as much data showing a positive effect as exists for glucophage at the moment. Acarbose did not have a better ovulation rate than glucophage so the main benefit comes down to a lower risk of lactic acidosis which is a very rare complication anyway.

I would think of acarbose as a second line drug for the time being. If first line drugs like glucophage were not tolerated or ineffective than trying something like acarbose might be reasonable.

Chromium treatment for PCOS

Chromium is a mineral required in small quantities by the body. It enables insulin to function normally and helps the body process (metabolize) carbohydrates and fats. Good sources of chromium include carrots, potatoes, broccoli, whole-grain products, and molasses. Picolinate, a by-product of the amino acid tryptophan, is paired with chromium in supplements because it is claimed to help the body absorb chromium more efficiently. Chromium deficiency is very rare in developed countries. Nonetheless, it has become a popular supplement.  Chromium picolinate has been suggested to promote weight loss, build muscle, reduce body fat, and enhance the function of insulin. It may lower levels of cholesterol and triglycerides.

Chromium picolinate is of possible interest in the treatment of PCOS patients due to its possible effects in improving insulin resistance. A few small studies have been performed in which women with PCOS were given chromium.

One such study, in women with polycystic ovary syndrome, found that chromium picolinate (200 μg/d) improved glucose tolerance compared with placebo but it did not improve ovulatory frequency or the abnormal hormonal parameters commonly found in women with PCOS. The authors of this study concluded that future studies in the polycystic ovary syndrome population should examine higher dosages or longer duration of treatment.

Another study examined the effects of chromium picolinate at a dose of 1000 ug per day. PCOS patients were given chromium but were instructed not to change their diet or exercise level. These PCOS patients experienced a  38% mean improvement in a measure of insulin resistance. These authors concluded that chromium picolinate, an over-the-counter dietary product, may be useful as an insulin sensitizer in the treatment of polycystic ovary syndrome.

Exercise and PCOS

Exercise may be the single most important lifestyle factor for both preventing and reversing insulin resistance. Exercise training results in a preferential loss of abdominal body fat and reverses the loss of muscle mass associated with insulin resistance, providing the single-most important intervention for changes in body composition.

Exercise improves insulin sensitivity in skeletal muscles and fat tissue, reducing both fasting blood sugar and insulin levels. Findings demonstrate that consistent exercise training, even without accompanying improvements in body composition, improve peripheral insulin activity in subjects with impaired glucose tolerance.

Even an exercise routine as simple as incorporating brisk walking four times weekly dramatically improves endurance fitness, decreases body fat stores, tends to reduce food consumption, and decreases insulin resistance.

To date, only a few controlled studies have examined the direct effects of physical exercise in PCOS women. In the first study, a 6-month exercise program significantly decreased plasma total homocysteine concentrations and waist-to-hip ratio, but had no effect on fasting insulin or androgen levels in young overweight and obese women with PCOS.

More recently, a 2005 study showed that insulin resistance was improved by up to 25% in sedentary women with PCOS and insulin resistance following a 5-month moderate-intensity exercise program without weight loss. In 2007, investigators determined that any improvements seen with exercise in PCOS patients were lost within 12 weeks if they stopped their exercise program.

Green Teas for PCOS

Many varieties of green tea have been created in China and other countries. these teas can differ substantially due to variable growing conditions, processing and harvesting time. Although many health benefits are supposed to result from drinking green teas, few if any of these claims have been proven in rigorously performed studies.

Herbal Drugs and Chemicals

Unfortunately, the internet has resulted in a huge increase in the use of herbal drugs and elixirs. In addition to being exempt from U.S. Food and Drug oversight, there is little evidence to support the use of these powerful chemical compounds. There are reported cases of adverse complications occurring in women taking these things to try to promote their fertility.

Cinnamon for PCOS

Cinnamon is a spice that comes from the bark of a small evergreen tree native to Sri Lanka and South India. The bark is widely used as a spice due to its distinct odor. In India it is also known as “Daalchini”.

Cinnamon is prepared by roughly pounding the bark, soaking it in sea-water, and then quickly distilling the result. Cinnamon contains a large amount of active chemicals including cinnamic aldehyde, ethyl cinnamate, eugenol, cinnamaldehyde, beta-caryophyllene, linalool and methyl chavicol.

Like other herbal remedies, there are many varieties of cinnamon which have distinct chemical components and may differ from each other substantially. It is therefore difficult to perform accurate scientific comparisons and draw valid conclusions.

In the summer of 2007, a very small pilot study was performed to determine whether cinnamon had any beneficial effects on women with PCOS. Fifteen women with polycystic ovary syndrome were randomized to daily oral cinnamon and placebo for 8 weeks. The results indicated a reduction in insulin resistance in the cinnamon group but not in the placebo group. Because the number of women studied was so small, a larger trial is needed to confirm the findings of this pilot study.

Vitex for PCOS

Vitex agnus-castus  (commonly called just Vitex, but also called Chaste Tree, Chasteberry, or Monk’s Pepper — is a plant which grows in the Mediterranean region. The leaves, stem, flowers and ripening seeds, have been used for medicinal purposes.

The berries have been used as an herbal drug for both the male and female reproductive systems. The leaves are believed to have the same effect but to a lesser degree. This plant is commonly called monk’s pepper because it was originally used as anti-libido medicine by monks to aid their attempts to remain celibate. It is believed to decrease sexual interest, hence the name chaste tree.

There is little if any clinical evidence of a benefit of Vitex for infertility or women with PCOS. Like other herbal drugs, many varieties of the plant are grown in various areas. The chemical composition is quite complex and varied from variety to variety.

One study has found that treatment with one variety of Chinese Vitex caused a slight reduction of a pituitary hormone known as prolactin in mice. There are no studies in human beings. There are no studies which have looked at the effects of Vitex in women with PCOS.

Actos and Avandia for PCOS

Background on Actos and Avandia

Actos (pioglitazone) and Avandia (rosiglitazone) belong to a class of medications known as thiazolidinidiones or TZDs. A third medication known as Rezulin (troglitazone) is no longer available in the United States. All three of these medications have been approved by the Food and Drug Administration for the treatment of diabetes. The use of Actos and Avandia for PCOS is considered an off label indication.

Because of the risks, TZDs such as Actos and Avandia are no longer recommended for the treatment of PCOS

Why diabetes drugs for PCOS?

There are many reasons why a woman may not ovulate regularly. It appears that some women are resistant to the hormone insulin. Insulin is normally thought of as a hormone that helps regulate blood sugar. Insulin is produced by cells that are located adjacent to the pancreas called the Islets of Langerhans. While this is true, insulin also has many other effects in the body. The ovary has receptors for insulin and thus insulin is capable of modifying hormone production from the ovaries.

The are several conditions that may result in a woman becoming resistant to the effects of insulin. Among these are PCOS (Polycystic Ovary Syndrome), genetics and obesity. When insulin resistance occurs, the body needs a higher level of insulin to accomplish the same tasks. High insulin levels are frequently seen in women with insulin resistance.

If insulin resistance is the cause for a woman’s anovulation (not ovulating) then it stands to reason that improving the insulin resistance or lowering the insulin levels may be successful at causing ovulation to return.

In fact some studies in women with PCOS demonstrated that thiazolidinidiones could be an effective treatment.

Rezulin in PCOS

Rezulin was the first TZD studied. Studies with Rezulin in PCOS patients demonstrated an improvement in some of the hormone abnormalities seen in PCOS.

In 2 other studies, Rezulin either alone or combined with clomiphene citrate induced ovulation in insulin and/or clomiphene-resistant patients with PCOS. Ovulation and pregnancy rate were 83% and 39% in 18 Clomid resistant patients, and in most of the patients, ovulation was achieved with Rezulin alone or in combination with low doses of CC.

Actos in PCOS

More recently, a well designed study using Actos in PCOS patients was published. The Actos study was a randomized, double-blind, controlled trial was to investigate whether Actos was capable of decreasing insulin resistance and the elevated levels of male hormones (androgens) that are common in women with PCOS. The Actos study also sought to determine whether the ovulation rate would improve in women with PCOS.

Forty pre-menopausal women with PCOS were assigned to treatment with either Actos (30 mg/d) or a placebo for three months. The results were very encouraging. The group which took Actos showed a decline in both fasting serum insulin levels and insulin response after giving them a high load of sugar.

This represented an increase in insulin sensitivity. In addition, Actos increased the levels of a protein called SHBG. SHBG binds up the male hormones in the circulation resulting in less “free” male hormones (androgens).

Treatment with Actos was also associated with higher ovulation rates.

Avandia in PCOS

A similar study using Avandia was published in March of 2005. The stated goal of this randomized, controlled, double-blind trial was to learn whether Avandia would improve the ovulation rate and androgen levels in non-obese women with polycystic ovary syndrome (PCOS). An interesting aspect of this study is that women were chosen based on the fact that all laboratory testing for insulin resistance was normal.

100 women with PCOS were enrolled in the study. The women received either 850 mg of Glucophage, 4 mg Avandia, a combination of both treatments, or a placebo twice a day for 6 months.

The results of this Avandia study are interesting. Women given Avandia gained an average of 1 kg (about 2.2 pounds). However, all treatment groups except the placebo group had a significant decline in their waist-to-hip ratio which implies a reduction in insulin resistance. Likewise, systolic blood pressure fell in all actively treated groups but not in those who received placebo.

Avandia and Glucophage treatment resulted in an increase in the number of times the PCOS patients ovulated. The highest rates of ovulation were found in the combined Avandia and Glucophage group and in the Glucophage only group.

The male hormone testosterone decreased significantly with active treatment.

Avandia dose for PCOS

Avandia 4 or 8 mg tablets. Maximum 8 mg daily

Actos dose for PCOS

Actos 15, 30 or 45 mg tablets. Maximum dose 45 mg daily.

Actos and Avandia side effects

Rezulin which is no longer available in the U.S. has been found to cause liver injury, jaundice and very rare cases of liver failure, liver transplants, and death. In early studies, Rezulin was noted to increase the levels of certain blood markers of liver injury (liver enzymes, AST, ALT). The other members of this class have not been found to cause similar problems. In fact, it is when Actos and Avandia were approved by the FDA that Rezulin was removed from the U.S. market. However, due to the close structural similarity of all these medications, it is strongly recommended that all patients undergo regular assessment of liver enzymes.

The incidence of other reported side effects in clinical trials of Actos and Avandia did not differ from that of placebo (sugar pills).

In a small percentage of people, Actos or Avandia may cause fluid retention. Others may notice swelling in the lower extremities during use.

Because of the possible risks, you should not take Actos or Avandia if:

1. You have known liver problems
2. You drink alcohol excessively
3. Heart disease

Patients who develop nausea, vomiting, abdominal pain, fatigue, loss of appetite, dark urine, light colored stools, or yellowing of the whites of the eyes should immediately report these symptoms to us.

Newly reported possible risks of Actos and Avandia

Takeda pharmaceuticals recently performed an analysis of its clinical trial database of Actos with a special focus on fractures, comparing patients treated with Actos or a comparator (either placebo or a different medication). The results suggest that Actos users are at higher risk for fractures. In the analysis, the maximum duration of Actos treatment was up to 3.5 years. There were more than 81 00 patients in the Actos-treated groups and over 7400 patients in the comparator-treated groups. The majority of fractures observed in female patients who received Actos were in the distal upper limb (forearm, hand and wrist) or distal lower limb (foot, ankle, fibula and tibia).

Based on their calculations, if 1000 women took Actos for one year, 19 fractures would be expected compared to 11 expected fractures in the comparison group. There was no increased risk of fracture identified in men.

Avandia was shown in a separate study published in the New England Journal of Medicine in May 2007 to possibly be associated with an increase in the risk for myocardial infarction (heart attack) and cardiovascular death. However, the study did not separate diabetics from PCOS patients and incldued both men and women. It is not clear at this time whether PCOS patients have a similar increase in risk.

Actos and Avandia: Effects on pregnancy

Rezulin and Avandia are considered pregnancy category B.

Animal studies in rats and rabbits at very high doses did not result in a higher than expected incidence of birth defects. At extremely high doses, body weights of fetuses were decreased. Postnatal development, attributed to decreased weight was delayed.

Actos is pregnancy category C. Delayed parturition and postnatal development and embryo toxicity (as evidenced by increased post-implantation losses, delayed development and reduced fetal weights) were observed in rats and/or rabbits when given very high doses.

There are no good, well-controlled studies in women. It is recommended that Actos or Avandia be stopped immediately upon the diagnosis of pregnancy.

Progesterone vaginal suppositories

Progesterone vaginal suppositories

Progesterone suppositories are relatively simple to use. Progesterone suppositories are compounded by the pharmacist and consist of natural progesterone suspended in a base similar to cocoa butter.

The suppositories will feel soft and "squishy" to the touch. Usually they are oblong or bullet shaped. Someitmes the suppositories will come with an applicator but an applicator is not necessary to use them.

The suppositories are intended to be used vaginally. First, the suppository must be removed form the wrapping or covering material. The suppository is then fitted onto the end of the applicator into the "cup". The applicator is inserted into the vagina. Once resistance is felt, stop advancing the applicator.

Press the plunger on the end of the applicator to release the suppository and then remove the applicator.

Alternatively, the suppository can be grasped between the fingers and inserted without an applicator.

Progesterone injections

What is Progesterone?


Progesterone, one of the reproductive hormones normally produced by the ovary after ovulation. It is needed to prepare the endometrium for implantation of an embryo and is used as part of an assisted reproductive technology (ART), ovulation induction or sometimes to induce a period in a woman who hasn’t ovulated.

Here are step-by-step instructions for administering Progesterone Injection injections:

Wash your hands thoroughly and make sure that the surface you work on is clean.

abdomen

Use an alcohol swab to cleanse the rubber stopper of the progesterone medication.

abdomen

Using the 3cc syringe with a 1.5 inch needle, pull back on the plunger to the 1cc mark.

Pierce the rubber stopper of the progesterone vial. Inject 1cc of air into the vial.

Turn the vial upside down, making sure the tip of the needle is below the fluid level. Withdraw the dosage ordered. Progesterone is an oil. It will pull into the syringe more slowly than sterile water does as when you use your other fertility medications.


Pull out the needle and replace the cap. Pull back on the plunger to clear the needle of any medication. Remove the needle from the syringe and replace with a new 1½ inch needle.

Flick the syringe with your finger

With the needle pointing toward the ceiling, flick the side of the syringe to disperse the air bubbles and the air pocket at the top of the syringe

Press the plunger on the syringe

Then gently push the plunger to eliminate any air until you expel one or two drops of liquid from the tip of the needle.

You are now ready to administer the progesterone by intramuscular injection.

IVF Progesterone supplementation

Progesterone is made from the ovaries after ovulation. During IVF cycles, progesterone is produced after the hCG trigger injection is taken. Using medications to prevent premature ovulation and performing an egg retrieval may cause the progesterone production to be inadequate. For this reason, we will supplement progesterone in women being treated with IVF.

Vaginal or IM Progesterone?

The most reliable way to get progesterone to the uterus is to administer it vaginally. Several studies have been performed comparing vaginal progesterone to intra-muscular injections. In the past, some studies have shown that vaginal progesterone is best whereas some studies showed that  intra-muscular progesterone is best. Today, it is almost universally agreed that there is no difference in the chance for pregnancy between the two.

Most women prefer to use vaginal progesterone. This is due to the fact that administration of intramuscular progesterone is painful and can result in welts at the injection site. some women also have allergic reaction to the oil base in the progesterone injections.

A few women seem to prefer progesterone injections because they do not like the vaginal discharge that can sometimes occur with the use of vaginal progesterone.

We like to use vaginal progesterone in the evening (either a natural progesterone cream called Crinone or a vaginal progesterone dissolving tablet called Endometrin ). Crinone comes in an applicator like medications that are used to treat yeast infections. One applicator of Crinone is given each morning and night starting on the night of the egg retrieval. Endometrin is used three times daily.

Safety of progesterone in IVF

Many couples worry whether treatment with progesterone is safe for the baby. The short answer is yes.

Progesterone supplements come in different varieties. Only a few of these types are safe to use in pregnancy. Progesterone that is chemically identical to the “natural” progesterone made in the ovaries is safe to use in pregnancy. In fact, two brands, Crinone and Endometrin, are natural progesterones that are approved by the U.S. FDA for use in fertility treatments. Some pharmacies can also make natural progesterone vaginal suppositories. Progesterone intramuscular injections also contain natural progesterone and may be used during pregnancy.

There are progesterone supplements that are synthetically derived and not chemically identical to the progesterone made in the ovaries. For example, the progesterones that are contained in birth control pills like norethindrone, drospirenone (and others) should not be used in pregnancy. A very commonly used type of synthetic progesterone called Provera should also not be used in pregnant women.

How long do you need to continue progesterone?

As noted above, there is concern about the ovaries ability to produce progesterone because of the use of medications and because of the egg retrieval. At about the 7th week of pregnancy, progesterone production begins to shift from the ovaries to the placenta. By about the 11th week, the shift is complete and all progesterone is being produced by the placenta. At this posint, progesterone supplementation is no longer needed.

Lupron (Leuprolide acetate)

What is Lupron (Leuprolide acetate)?

Lupron® is a gonadotropin-releasing hormone agonist. It inhibits the pituitary gland’s ability to control the ovary and, therefore, has been used to reduce the likelihood of unintended ovulation during assisted reproduction treatment cycles. In women with endometriosis, Lupron® provides pain relief and reduction in the size of endometriosis lesions.

How do I use Lupron (Leuprolide acetate)?

Here are step-by-step instructions for taking Lupron® (leuprolide acetate) injections: Lupron® is injected subcutaneously-or into the fatty tissue under your skin. The primary sites for injection are your abdomen – 2 inches on either side of the navel;- and your upper, outer-thigh where the skin is loose.
,

Lupron

Wash your hands thoroughly and make sure that the surface you work on is clean.

Use an alcohol swab to cleanse the rubber stopper of the vial.

Pull the plunger of the syringe back to the appropriate marking.

Pull off the cap of the needle, and pierce the rubber stopper of the Lupron® vial.

Push the plunger all the way in. Keeping the needle inside the bottle, turn the vial upside down. With the needle in the liquid, pull back the plunger, until the syringe fills to the proper mark. Remove the needle from the vial,

With the needle pointing toward the ceiling, flick the side of the syringe to disperse any air bubbles and the air pocket at the top of the syringe.

Gently push the plunger until one or two drops of liquid are expressed to make sure you have eliminated any air.

You are now ready to administer the lupron as a subcutaneous injection.

Low Dose hCG

IMPORTANT: The low dose hCG should be premixed by the pharmacy. You should receive it on ice and it needs to be kept in the refrigerator. If you have not received your hCG in this way, please notify us immediately!

It is your responsibility to make sure you have received the correct medications. Do not wait until the last minute!

Do not attempt to use hCG for the trigger injection in place of low dose hCG!!!!

Why use Low Dose hCG?

hCG, or human chorionic gonadotropin, is very similar in structure to the pituitary hormone LH (luteinizing hormone). Many experts beleive that in order to optimally stimulate the ovaries for assisted reproduction technologies (ART), medications containing both FSH (follicle stimulating hormone) and LH are necessary.

Since most of the FSH medications used in ART are produced through recombinant DNA technology, they contain no LH activity. Supplementation with LH is problematic since LH is broken down very quickly in the body and therefore has very little effect.
hCG, however, lasts much longer and therefore has greater biologic activity. Very low dose hCG is used as a replacement for LH to help supplement the stimulation during ART cycles.

How do I use Low Dose hCG?

Here are step-by-step instructions for taking low dose hCG injections:
Low dose hCG is injected subcutaneously-or into the fatty tissue under your skin. The primary sites for injection are your abdomen – 2 inches on either side of the navel, and your upper, outer-thigh where the skin is loose. Wash your hands thoroughly and make sure that the surface you work on is clean.

alt

You should receive your low dose hCG premixed and on ice. Place it in the refigerator until ready for use. If your medication is not mixed by the pharmacy, you will need to bring it into our office to have the nurses mix it for you.

alt

The first time you use the low dose hCG vial, it will have a foil wrapper covering the top. Grasp the foil tab and pull the foil off the the low dose hCG vial.

Letrozole (Femara) for Infertility Treatment

Background information

Letrozole is being used commonly as an infertility treatment. Letrozole is a recent addition to the drugs being used for fertility treatment. Fertility drugs are used often in infertility treatments. There are two situations in which fertility drugs may be useful. First, these drugs can be used to induce an egg to develop and be released in women who are not ovulating on their own. This is known as ovulation induction. Fertility drugs can also be used to increase the chances of pregnancy in women who are already ovulating. This is known as superovulation.

Letrozole for infertility
Letrozole for infertility

In many fertility centers, clomiphene citrate (Clomid, Serophene) has been the drug of first choice for either ovulation induction or superovulation for many years. In general, it has been a relatively effective medication. However, clomiphene citrate lasts for a long time in the body and may therefore have an adverse effect on the cervical mucus and uterine lining. Some groups of patients, such as women with PCOS – polycystic ovary syndrome, do not respond well to clomiphene citrate. The Pregnancy in Polycystic Ovary Syndrome (PPCOS I) study found that over 6 months time, 1 in 4 PCOS patients never had a single documented ovulation. The cumulative live birth rate was only 23% over the 6 months. One reason theorized for the lower pregnancy rate with clomid is an adverse effect on the uterine lining.

Another group of fertility drugs which are administered as injections are called gonadotropins (Gonal F, Follistim). The gonadotropins are very efficient at inducing ovulation and have higher pregnancy rates than clomiphene citrate. However, gonadotropins are much more expensive than clomiphene citrate and the injectable route is uncomfortable for patients to administer and inconvenient. The risk for multiple pregnancies is also much higher with gonadotropins.

Letrozole as a Fertility Treatment

Letrozole is a medication that has been widely used in women with breast cancer. It is sold under the trade name Femara. Letrozole belongs to a class of medications known as aromatase inhibitors. Aromatase is an enzyme that is responsible for the production of estrogen in the body. Letrozole works by inhibiting aromatase thereby suppressing estrogen production. Clomiphene citrate, on the other hand, blocks estrogen receptors. In both cases, the result is that the pituitary gland produces more of the hormones needed to stimulate the ovaries. These hormones, FSH and LH, can cause the development of ovulation in women who are anovulatory or increase the number of eggs developing in the ovaries of women who already ovulate. As a result, several studies have now been published using letrozole as a fertility drug.

One of the earliest studies using letrozole as a fertility drug looked at 12 women with inadequate response to clomiphene citrate. Ovulation on letrozole occurred in 9 of 12 cycles and 3 patients conceived. A later study by the same investigators compared the effects of letrozole to those of clomiphene citrate. This time 19 women were studied. Ten women received clomiphene citrate and nine women received letrozole. This study was unable to demonstrate any difference in the number of women who ovulated, the number of eggs that developed in each woman, or the thickness of the uterine lining during treatment. However, a more recent study by a different group of investigators found that compared with clomiphene citrate, letrozole is associated with a thicker uterine lining and a lower miscarriage rate.

At the 2013 meeting of the American Society for Reproductive Medicine (ASRM), the results of the PPCOS II study were first presented. In this study, which has now been published, 750 PCOS women were randomized to receive either letrozole or Clomid for up to 5 treatment cycles.

  • The findings convincingly showed that for women with PCOS:
  • The ovulation rate was superior with letrozole (61.7%) than with Clomid (48.3%)
  • The cumulative live birth rate was higher with letrozole (27.5%) the with Clomid (19.5%)
  • The live birth benefit was higher in obese women (BMI ≥ 35)
  • letrozole was equal or superior to Clomid at all BMI groups

There was no difference in:

  • the risk for pregnancy loss (letrozole 31.8% vs Clomid 28.2%)
  • Multiple pregnancy rates (all twins) (letrozole 3.2% vs Clomid 7.4%)
  • The number of serious adverse events

Use of letrozole in women without PCOS

The majority of studies looking at the use of letrozole compared to Clomid in women who do not have PCOS have concluded either there is no difference between the two or that clomid is superior for this group of patients.

Letrozole and birth defects

A study presented at ASRM in 2005, in which researchers analyzed births that occurred after treatment with letrozole found seven serious birth defects in 150 babies, which is about 4.7%. This was compared to a database of 36,050 normal deliveries. The incidence of birth defects in the control babies was 1.8% This means that birth defects were 3 times more likely to occur with letrozole.

This prompted the manufacturer (Novartis) to review their safety database and found 13 reports of already pregnant women receiving the drug worldwide. Of those 13 women, two had children with birth defects (15.4%).Novartis sent a letter to fertility physicians stating: “Femara (letrozole) is contraindicated in women with premenopausal endocrine status, in pregnancy, and/or lactation due to the potential for maternal and fetal toxicity and fetal malformations”.

In response, 5 Canadian fertility centers reviewed their birth outcomes and incidence of birth defects in women who conceived with letrozole and compared them to Clomid. The Canadian study involved 911 newborns. The major birth defect rate in the letrozole group was 1.2% (6/514) and in the Clomid group was 3.0% (12/397).

In the United States, the labeling of letrozole already warned that it had been associated with birth defects. Novartis has never sought FDA approval to market letrozole as a fertility medication and was clearly concerned about their liability if given in pregnancy.

Letrozole is a medication that is metabolized rapidly in the body. It is not thought to have significant levels in the blood or tissues for a prolonged period of time.

In the PPCOS II study, each baby born was closely studied for birth defects at the time of birth with additional screening within 1 month of birth by trained pediatric personnel. There was no difference in the rate of birth defects between letrozole and Clomid.

Letrozole side effects

Letrozole works based on its ability reduce estrogen levels. Low estrogen levels of any cause can cause a woman to have symptoms. The data on side effects comes from women who have been using letrozole for an extended period of time in order to treat breast cancer. The treatment duration for letrozole is only five days. In our experience, we have seen side effects that are similar to those seen with clomiphene citrate:

  • Hot flashes
  • Headaches
  • Breast tenderness

Letrozole and pregnancy

Studies conducted so far have shown either no increased risk of miscarriage or a decrease in miscarriage risk. Letrozole is considered pregnancy Category D. Letrozole should not be given to women who are already pregnant. Studies in rats and mice have shown that letrozole increases the risk of fetal death and malformations. Since there are no studies in human beings, it should be assumed that a similar effect is possible.

hCG Trigger


What is the hCG Trigger?

The hCG trigger injection is a medication known as a human chorionic gonadotropin and is used after other fertility hormones, such as clomiphene citrate or menotropins, to induce ovulation (release of the egg from the ovary) or in women undergoing an assisted reproductive technology (ART), to induce final maturation of the eggs. The dose used for the trigger is dependent on the body mass index of the female.
There are several brand names for the hCG trigger and include:

Profasi

Pregnyl

Glucophage

There are many reasons why a woman may not ovulate regularly. It appears that some women are resistant to the hormone insulin. Insulin is normally thought of as the hormone produced by the pancreas that helps regulate blood sugar. While this is true, insulin also has many other effects in the body. The ovary has receptors for insulin and thus insulin is capable of modifying hormone production from the ovaries.

The are several conditions that may result in a woman becoming resistant to the effects of insulin. Among these are  PCOS – Polycystic Ovary Syndrome – genetics and obesity. When insulin resistance occurs, the body needs a higher level of insulin to accomplish the same tasks. High insulin levels are frequently seen in this condition.

If insulin resistance is the cause for a woman’s anovulation (not ovulating) then it stands to reason that improving the insulin resistance or lowering the insulin levels may be successful at causing ovulation to return.

In fact some studies in overweight women with insulin resistance demonstrated that Metformin (Glucophage) was successful in getting ovulation to occur without any other additional medications. It also seemed to improve the response to a fertility medication called clomiphene citrate.

Results of the World’s Largest Metformin Study

Recently, a study was published comparing metformin to clomid in patients with PCOS. This study was conducted on over 600 patients and involved several academic centers. There were three groups of patients that were compared. Group 1 took metformin alone. Group 2 too clomid alone. Group 3 took a combination of metformin and clomid.

The outcome being measured in this study was the live birth rate. Patients were treated for 6 months or until an ongoing pregnancy occurred. The results were somewhat surprising. The total cumulative live birth rate in the metformin group after 6 months was only 7%. The clomid group had a live birth rate of about 25%. The live birth rate in the combination group was similar to the rate with clomid alone.

The results of this study indicate that while it is possible to ovulate and achieve pregnancies with metformin – this treatment is not nearly as efficient as clomid. Furthermore, combining clomid and metformin did not do any better than clomid alone. The main advantage of metformin therefore, is that the rate of multiple pregnancies was lower than in the clomid groups.

A secondary outcome looked at in this study was whether metformin was able to lower the miscarriage rate in women with PCOS. In fact, the results were just the opposite. The metformin groups had a higher rate of miscarriage although, when analyzed statistically, the results could have been due to chance.

Metformin (Glucophage) Instructions

Glucophage comes as either a short acting or extended release (Glucophage XR). I like to use the XR for a few reasons:

  • The tablets can all be taken together at the same time. It is not necessary to spread the dose out as was done with the short acting variety
  • The side effects seem to occur less frequently

Glucophage XR comes as 500 mg tablets. Most women will start with the 500 mg tablets. The starting dose is one tablet a day for one week. If this dose has been tolerated, then two tablets a day are taken during the second week. Finally, three tablets a day are taken during third week and continues thereafter. Some women will tolerate the medicine well and can increase their dose more quickly. Others may need to go more slowly.

Metformin also comes in a liquid preparation known as Riomet. There is also a long acting formulation that comes in a higher dose. Fortamet come in 1000 mg tablets. If a PCOS patient had demonstrated that she can tolerate the higher dose of metformin, switching to Fortamet can make pill taking a little easier since only two pills are required to reach the desired 2000 mg dose.

Metformin Side Effects

Gastrointestinal disturbance: Approximately 1/3 of the people who take glucophage will experience one or more of the following symptoms: nausea, diarrhea, vomiting bloating, or flatulence. Starting on a lower dose (1 tab / day) may reduce the likelihood of this problem. Taking glucophage with meals also may help. Symptoms do resolve with continued treatment.

Lactic acidosis: This is a rare but serious metabolic condition that results from accumulation of lactate in the blood. It can be seen in persons with diabetes, kidney problems and other problems. Glucophage may cause Lactic acidosis in 3 in 100,000 patients taking Glucophage over the course of a year. Lactic acidosis can be fatal when serious.

The symptoms of lactic acidosis are often subtle and non-specific. They include malaise, muscle aches (myalgia), difficulty breathing, increasing sleepiness (somnolence), and non-specific abdominal distress. IF YOU EXPERIENCE THESE SYMPTOMS, CONTACT THE OFFICE IMMEDIATELY.

Because of the risk of lactic acidosis, you should not take Glucophage if:

1. You have chronic kidney or liver problems
2. You drink alcohol excessively
3. You are scheduled to undergo a hysterosalpingogram or have surgery
4. You are pregnant

Metformin effects on pregnancy

A small series suggested that using metformin during pregnancy may have a benefit in terms of reducing the risk of miscarriage or gestational diabetes. Metformin is considered pregnancy category B. Animal studies in rats and rabbits at very high doses did not result in a higher than expected incidence of birth defects. There are no good, well-controlled trial in women. One study suggested that the use of metformin in pregnancy resulted in a higher incidence of some pregnancy complications. It is recommended that Metformin be stopped immediately upon the diagnosis of pregnancy. However, studies are currently ongoing to try to determine the safety and effectiveness of metformin in pregnancy.

A recent study has found pre-eclampsia, a complication of pregnancy involving high blood pressure, was over four times higher when metformin was used to treat gestational diabetes. You should read more about metformin risks here.

Follistim AQ Pen Injector

Follistim contains follicle stimulating hormone (FSH), one of the hormones that stimulates the ovary to make mature eggs. Follistim is used to stimulate the development of multiple follicles in women undergoing assisted reproductive technology treatments (ART). This medication may also be used to induce ovulation in women for certain types of ovarian dysfunction.

How Do I Use Follistim?

Tear off a single applicator.

Pull off the cap, and pull the inner sheath off. Hold the Follistim pen with the needle pointing upward. Tap the pen gently to help air bubbles rise to the top.

alt

Look for a droplet at the end of the needle. If you do not see a droplet, dial the dosage knob one notch on the dosage scale until you hear a click. With the needle pointing upward, push the orange injection button in all the way and look again for a droplet at the needle tip. Repeat until a droplet appears at the tip of the needle.

alt

To dial your dose turn the dial gently until the desired dose is in the clear section of the window. If you dial past your dose DO NOT turn it back. Turn it all the way forward until the dial is loose, push the injection button in all the way, and dial again.

alt

Wipe the injection site with alcohol. Let it dry.When the alcohol is dry, pinch a fold of skin. Holding the needle like a pencil, insert the needle.

alt

Inject the medication by pushing down on the dial. Once the dial is completely pushed down, hold the pen with the needle in place for 5 seconds. Pull the needle straight out.Gently press an alcohol pad on the injection site for five seconds.Check the pen dial. It should be at zero. If the dosage window does not read “0” it means there was not enough medication in the cartridge. The number in the window will give you the amount of medicine needed to complete your dose.

alt

Put the cap back on the needle.

alt

Unscrew it from the pen.

alt

And place it into a biohazard container such as a Sharps container – or in a sealable, unbreakable plastic container such as a laundry detergent bottle. Never Reuse Needles or Syringes!

Put the cap back on the pen. Save pen and cartridge for your next injection (if it still contains medication).

Please be aware that some of these instructions may vary slightly based upon your particular situation or preference.

Endometrin

Endometrin (progesterone vaginal insert) is a specially formulated vaginal tablet that contains the female hormone progesterone, which is one of the hormones essential for preparation of the uterus for implantation and maintenance of a pregnancy. Once the tablet is inserted into the vagina, it quickly dissolves and is available to be absorbed into the circulation to be taken to the uterus.

How Do I Use Endometrin

Each insert of Endometrin and each applicator comes individually wrapped within the Endometrin box. Here are step-by-step instructions for taking Endometrin:

Carefully unwrap the applicator and the Endometrin insert.

Put one Endometrin insert into the space provided at the end of the applicator. The insert should fit snugly and not fall out.

Choose a comfortable position for inserting the applicator. You may be sitting or laying on your back with your knees bent. You may stand

Gently slide the thin end of the applicator 2-3 inches into the vagina.

Push the bottom of the applicator upward to release the Endometrin insert. Remove the applicator and throw it away.

Side effects reported by women who used Endometrin in clinical studies reported the following side effect more than 2% of the time: uterine spasm (3-4%) vaginal bleeding (3%). Vaginal irritation, itching, burning, rash or swelling were reported less than 2% of the time.

Crinone 8%

Crinone (progesterone gel) is a specially formulated vaginal gel that contains the female hormone progesterone, which is one of the hormones essential for preparation of the uterus for implantation and maintenance of a pregnancy. The moisturizing gel of Crinone forms a coating on the walls of the vagina that allows for absorption of progesterone.

alt

How Do I Use Crinone 8%?

Here are step-by-step instructions for taking Crinone 8%:
Wash your hands thoroughly and make sure that the surface you work on is clean.

Crinone

Each prefilled applicator of Crinone comes individually wrapped within the Crinone box.

Crinone

Carefully remove the wrapper from the prefilled applicator.

Identify the thick end of the applicator. Grasp the applicator by the thick end but do not squeeze yet.

crinone

With your other hand, grasp and bend the tab located at the opposite end of the applicator. Bend and twist the tab until it breaks away from the applicator.

Choose a comfortable position for inserting the applicator. You may lay on your back or stand.

crinone
crinone

Insert the applicator into the vagina as far as it will comfortably go or when one half of the applicator has been inserted whichever is less.

crinone

Squeeze the bubble and the thick end completely. An amount of gel about the size of a dime will be dispensed into the vagina.

crinone

Remove the applicator. The gel will remain in the vagina. Dispose of the used applicator. Do not reuse the applicator.

Typically, the gel stays attached to the vaginal walls for a few days as the progesterone is absorbed. Do NOT be concerned is small, white globules appear as a discharge after serveral days of usage. It is common and not harmful, to have some gel residue build up.

If you wish, you may remove the residual gel by inserting your finger into the vagina and clearing the gel manually.

Cetrotide and Ganirelix (Antagon) in IVF

Cetrotide and Antagon in IVF

Cetrotide (cetrorelix) and ganirelix (Antagon) are examples of a type of medication that is used to prevent premature ovulation. This class of medications is referred to as GnRH antagonists or simply antagonists. Cetrotide and Antagon are newer medications than Lupron but have become tremendously popular as a result of their easy of use and high pregnancy rates.

Medications which work rapidly

Cetrotide and Ganirelix exert their action on the pituitary gland. The pituitary is responsible for producing the hormones which stimulate egg growth and development and for triggering ovulation of a mature egg. During an in vitro fertilization cycle, the physician needs to prevent ovulation from occurring so the eggs can be removed directly from the ovary.

In the early days of IVF, before medications to prevent ovulation were available, about 25% of IVF cycles would be cancelled for premature ovulation. Then a medication called Lupron was used to block the pituitary from causing premature ovulation. Lupron caused a few problems, however. When Lupron is first administered to a woman, it would stimulate her pituitary gland for several days before it would eventually suppress it. This is known as the stimulation or flare phase. The flare phase required that women start Lupron a few weeks before she could begin the fertility medications required for stimulation of the ovary. In some women, the flare effect can cause the development of cysts in the ovaries that could further delay the start of fertility medications.

A primary advantage of Cetrotide and Ganirelix is that they do not have a “flare phase”. Down regulation (suppression) of the pituitary occurs immediately. Therefore, it is not necessary to start these medications before the fertility medications begin (see picture). Cetrotide or Ganrelix would normally be started after 4-6 days after the start of the fertility medications. This shortens the number of days that a woman must take injections.

Protocol for using Cetrotide and Ganirelix

Fertility medications such as Follistim or Gonal F are the first injections which are administered in an antagonist cycle. The fertility medications may be started on the second or third day after the onset of a period or after a woman has been on birth control pills (oral contraceptives). A baseline assessment of hormones by blood test and the ovaries by ultrasound are performed at some point before the fertility medications are started.

Ganirelix Acetate Injection is available in disposable, pre-filled, ready to inject syringes containing 250 micrograms of ganirelix acetate. Mixing is not required. Ganarelix is designed to be self-injected using the supplied syringe for injection just under the skin (subcutaneous).

There are two protocols for beginning the Cetrotide or Ganirelix. One method, called the flexible start, utilizes the results of the blood and ultrasound monitoring of egg development. Once development of the eggs has started to occur, the Cetrotide or Ganirelix is started. A second method, called the fixed start, will begin the Cetrotide and Ganirelix after a certain number of days of fertility medication have been given regardless of the results of blood and ultrasound monitoring.

The GnRH antagonists are continued along with the fertility medication until the last day of fertility medication is given. Typically this means a woman will have 4-6 days of Cetrotide or Ganirelix before the egg retrieval.

Some experts believe that IVF cycles that use Lupron for pituitary suppression, may cause some women to become “over-suppressed” and therefore not respond as well to the fertility medications. Whether this occurs or not is subject to some debate. However, with the use of antagonists, there is no concern for this problem.

Cetrotide (cetrorelix acetate)

Cetrotide™ is a medication known as a gonadotropin-releasing hormone antagonist and is used to prevent premature ovulation in women undergoing fertility procedures.

How do I use Cetrotide™?

Here are step-by-step instructions for taking Cetrotide™ (cetrorelix) injections:

Cetrotide™ is injected subcutaneously-or into the fatty tissue under your skin. The primary sites for injection are your abdomen – 2 inches on either side of the navel, and your upper, outer-thigh where the skin is loose.

Wash your hands thoroughly and make sure that the surface you work on is clean.

alt

Flip off the plastic cover of the vial and wipe the rubber stopper with an alcohol swab. Put the injection needle with the yellow mark (20 gauge) on the pre-filled syringe.

alt

Push the needle through the rubber stopper of the vial and slowly inject the solvent into the vial. Leaving the syringe in the vial, gently swirl the vial until the solution is clear. Avoid making bubbles. Do not shake.

alt

Invert the vial and pull back the needle as far as needed to withdraw all of the liquid in the vial. You might not be able to withdraw every drop.

Replace the needle with the yellow mark with the (27 gauge) inch syringe. Remove any air bubbles.

Cell phone use and male fertility

A recent study has suggested that cell phone use might be associated with infertility by causing abnormalities in the semen analysis.

Cell phones and male infertility – could there be a link?

Cell phones are commonly used by both males and females. It is estimated that there are over 700 million cell phone users in the world. Mobiles phones contain small transmitters that emit radio frequency electromagnetic waves (EMW). These phones operate at different frequencies in different countries and continents. Analog phones operate at 450–900 MHz, digital phones (Global System for Mobile Communications [GSM]) at 850–1900 MHz, and third-generation phones at approximately 2000 MHz. Higher frequency phones result in greater exposure to the body. Reports of potential adverse effects of radio frequency EMW from cell phones have appeared in the news in recent months.

The results of animal studies have yielded conflicting results. One study in mice, found that radio frequency EMW had harmful effects on the cells that produce sperm but another study found no harm. A study in rates did not find any adverse effect of cell phone exposure on sperm count, morphology, or the microscopic appearance of the testicles.

There have been two previous studies on this subject in human men. One recent study on 371 men undergoing infertility evaluations, found that increasing duration of possession and the daily transmission times of cell phones was associated with a lower proportion of sperm with rapid forward movement and an increase in the proportion of slow moving sperm.  The second study looked at only 13 men. They found that  using GSM phones for 6 hours per day for 5 days decreased the numbers of sperm with fast, forward movement.

New Study on Cell Phone Use and Sperm

The study examined 361 men who were being seen at an infertility clinic from September 2004 to October 2005. The average age of these men was 31-21. .Importantly, men who had a history of tobacco or alcohol  use were excluded.  Men with other medical problems that could affect their sperm were also excluded.

The men in the study collected a semen specimen after an abstinence period of 5 days. The information on cell phone usage was obtained and they were divided into 4 groups according to the daily duration of use.

  • Group A: no use (40 men)
  • Group B: Less than 2 hours per day (107 men)
  • Group C: 2–4 hours per day (100 men)
  • Group D: More than 4 hours per day (114 men)

The technicians analyzing the semen samples did not know the patients cell phone use.

Results: Cell phone use linked with sperm abnormalities

When analyzed, there was a correlation found with increasing duration of cell phone use and abnormalities in the semen analysis. Specifically, sperm count, percentage motility, viability, and normal morphology were worse in the groups that  reported higher cell phone use. But as the graph below shows, there was no difference found in the volume of ejaculate, the time it took sperm to liquefy, the pH or viscosity of the semen.    

Effects of cell phone use on sperm

Discussion

It is difficult to say how great a danger cell phones may cause toward male fertility. First, the study has several limitations that make it difficult to rely on the results. For example, the researchers did not actually verify the amount of cell phone use that the men reported. Very importantly, they did not take into account the occupations of the men and whether they might have had EMW exposure from other sources such as radio towers, PDAs, Bluetooth devices or computers. They also did not report whether the men predominantly used their cell phone by holding them to their ears or when attached to the waist using an ear phone. Theoretically, due to the closer proximity, a cell phone attached to the waist during use might result in increased EMW exposure to the testicles.

Furthermore, although the use of cell phones may cause a decrease in some sperm parameters, this does not necessarily correlate with infertility. For example,  the average sperm count in the group that reported no cell phone use was 85 million sperm per mL. The concentration in the group that reported more than four hours per day of use was about 50 million per mL. This is still well above the level that is considered normal which is 20 million sperm per mL.

More studies on this subject are clearly needed. Until we have better data, it seems reasonable to recommend to men who are trying to conceive that they should try to limit their cell phone use. Alternatively, keeping the cell phone away from the testicles may also offer some protection.

Obstructive Azoospermia

Azoospermia, defined as complete absence of sperm from the ejaculate, is present in less than 1% of all men and in 10-15% of infertile men. There are many causes of azoospermia

  1. Failure of hormones to adequately stimulate the testicles to produce sperm (also known as Pre-testicular)
  2. Primary testicular failure in which the sperm producing cells in the testicles are either missing or damaged
  3. Obstruction of the sperm delivery system (also known as Post-testicular)

Obstruction is responsible for approximately 40% of cases of azoospermia. Obstructive azoospermia may result from blockage in any of the tubes leading from the testicle to the opening in the tip of the penis. These tubes are

  1. Epididymis
  2. Vas Deferens
  3. Ejaculatory duct

Causes of Sperm Obstruction

Vasectomy is the most common cause of obstruction in the vas deferens. Severe genital or urinary infections, injury during scrotal or inguinal surgery and birth defects are other common causes of obstructive azoospermia.

Treatments For Sperm Obstruction

Men with obstructive azoospermia may father children by

  1. Surgical correction of the obstruction,
  2. Retrieval of sperm from the male reproductive system for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).

Microsurgical Vasectomy Reversal

In the United States, estimates are that 500,000 to 750,000 vasectomies are performed annually; as many as 4%to 10% of these men later request reversal. A very important factor influencing the likelihood of sperm returning to the semen and of pregnancy after vasectomy reversal is the number of years between vasectomy and attempted reconstruction. Other factors influencing the success of vasectomy reversal include the:

  1. presence or absence of sperm seen during the surgery
  2. appearance of the vas fluid as seen during the surgery
  3. quality of the sperm in the vas fluid
  4. length of the vas segment between the epididymis and the vasectomy site
  5. presence or absence of a sperm granuloma (a lump of hardened, old sperm sometimes seen after vasectomy)
  6. age of the female partner.
 Vasal fluid Patency ratePregnancy rate
 Motile sperm 94%63%
 Nonmotile sperm 90%54%
 Sperm heads only 75%44%
 No sperm 60% 31%

There are two microsurgical procedures used for vasectomy reversal:  vasovasostomy  and vasoepididymostomy. Vasectomy reversal is usually performed with the patient under general anesthesia. Alternatively, the procedure can be performed with a local anesthetic (with or without sedation) or with a spinal or epidural anesthetic.

Vasovasostomy

This method of microsurgery removes an obstruction and connects one part of the vas deferens to another part.  In addition to vasectomy reversal , this type of microsurgery is also  performed for blockage caused by injury during a hernia repair.

In a report by the Vasovasostomy Study Group, overall patency rate and pregnancy rate for more than 1200 vasovasostomy procedures were 86% and 52%, respectively. The patency rate and pregnancy rate fell from 97% and 76% at less than 3 years after vasectomy to 71% and 30% at 15 years or longer after vasectomy.

 Obstructive interval Patency ratePregnancy rate
 < 3 years 97%76%
 3-8 years 88%53%
 9-14 years 79%44%
 >15 years 71% 30%

Vasoepididymostomy

This method of microsurgery removes an obstruction and connects the vas deferens to the epididymis. Vasoepididymostomy is considered one of the most challenging microsurgical procedures, requiring significant microsurgical experience. In addition to vasectomy reversal, it can also be performed for the following types of obstructions:

  1. congenital (present at birth)
  2. scarring from infections
  3. Unexplained blockage of the epididymis

Following this type of microsurgery, the patency rate and pregnancy rate range, respectively, from 67% to 85% and from 27% to 49%.

Repeat Vasectomy Reversals

A history of a previous vasectomy reversal attempt does not preclude a new attempt. Patency and pregnancy rates of 79% and 31%, respectively, have been reported for repeated reversals.

Transurethral Resection of the Ejaculatory Ducts (TURED)

This method is used to treat blockage in the ejaculatory duct. This condition is uncommon. Ejaculatory duct obstructions (EDO)can be congenital, (due to abnormal development as a fetus) or acquired. Acquired obstructions may be secondary to trauma or infection/inflammation. Obstructed ejaculatory ducts are usually diagnosed by transrectal ultrasound imaging or by special radiographic tests called vasograms.

Transurethral resection of the ejaculatory duct results in the appearance of sperm in the ejaculate in 50-75% of cases. The pregnancy rate achieved by this surgery is about 25%.

Sperm Retrieval Techniques and IVF/ICSI

ICSI or intracytoplasmic sperm injection is a method to fertilize eggs during IVF in which a single sperm is injected into a single mature egg. ICSI must be used in all cases in which sperm are retrieved from the testes or epididymis. This is necessary for two reasons:

  1. The amount of sperm obtained is usually very small
  2. Sperm from the testicles and most of the epididymis have not developed the capability to fertilize an egg without help

ICSI provides fertilization rates of 45-75% per injected oocyte when surgically retrieved epididymal or testicular spermatozoa are used.

Sperm Retrieval for ICSI

There are different methods employed for retrieving sperm for ICSI

  1. MESA – Microsurgical Epididymal Sperm Aspiration
  2. PESA – Percutaneous Epididymal Sperm Aspiration
  3. TESE – TEsticular Sperm Extraction
  4. TESA -Percutaneous Testicular Sperm Aspiration
  5. VASA – VAsal Sperm Aspiration
  6. SESA – SEminal vesicle Sperm Aspiration

Microsurgical methods utilize an incision and surgery tiny instruments with the assistance of large, high powered surgical microscopes.

Percutaneous methods do not make an incision but rather, use a tiny needle directed in the appropriate place to aspirate sperm. This is sometimes aided by transrectal ultrasound. The choice of sperm retrieval method in men with obstructive azoospermia depends primarily on the experience and preference of both the urologist.

There are not enough data to conclude that either the technique of sperm retrieval (microsurgical or percutaneous) or the source of sperm (testicular, epididymal, vasal or seminal vesicular) significantly affects pregnancy rates. Each technique and sperm source usually provides a sufficient number of sperm for ICSI and may provide enough viable sperm for cryopreservation (freezing).

Sperm retrieval may be performed prior to or simultaneously with the female’s egg retrieval. Sperm retrieval is most commonly performed before the female starts fertility medication injections for IVF.

Microsurgical Reconstruction Versus Sperm Retrieval with IVF/ICSI

In good prognosis cases, microsurgical reconstruction may be more cost-effective than sperm retrieval with IVF/ICSI, and allows couples to have subsequent children without additional medical treatment.

Many couples will opt for IVF/ICSI however. In couples with good prognosis, a higher percentage of couples will achieve pregnancy more quickly with IVF/ICSI. Also, the presence of female infertility factors may reduce the chance for pregnancy after microsurgical reconstruction.

Medications That Interfere With Male Fertility

Male fertility can be adversely affected through any of 5 basic mechanisms:

  1. Direct toxic effects on the testicles,
  2. Disruption of the pituitary gland and its stimulation of the testicles,
  3. Direct effects on ejaculation and/or erectile function,
  4. Decrease in libido (sex drive)
  5. Blocking the sperm’s ability to fertilize an egg

Medications that have a direct toxic effect on the testicles can damage the cells which produce sperm. This can result in lower sperm counts or in severe cases – cause a complete absence of sperm. Damage to the sperm producing cells can be temporary or permanent.

Normally, the pituitary gland, which is located just beneath the brain, will produce hormones that will stimulate the cells in the testicles. These cells will, in turn, produce sperm and produce hormones such as testosterone. The testosterone that is produced, along with some other hormones from the testicles, will regulate the level of stimulation to the testicles.

In some cases, medications may disrupt the connection between the pituitary gland and the testicles and result in inadequate stimulation to the testicles. This can result in lowered sperm counts and abnormal hormone levels.

In order for sperm to be delivered into the female reproductive tract, the male must be able to achieve an erection and subsequently, he must ejaculate. The coordination of these events is very complex and can be disrupted in a number of different ways.

Some medications may act to decrease male sexual interest in intercourse, or libido. Other medications may interfere with the ability of a man to get an erection or ejaculate.

Finally, some medications may affect the sperm directly. For example, a group of medications which are commonly used to treat high blood pressure called calcium channel blockers have been shown in some studies to block the ability of the sperm to fertilize an egg.

Listed below are several categories of medications and their effect on the five areas influencing male fertility. Men should not stop any prescription medication before discussing it first with his prescribing physician.

Male fertility and Y chromosome Microdeletions

Normal human beings have 23 pairs of chromosomes. One pair of these are called the sex chromosomes. Women have two X chromosomes and men have one X chromosome and one Y chromosome. Most, if not all of the genes that are responsible for sperm production in men are found on the Y chromosome. Abnormalities involving the sex chromosomes can result in sperm production problems and infertility. For example, men who have an extra X chromosome (XXY) are often lacking in sperm and are infertile. Men who have portions of the Y chromosome are missing (deletions) or redundant (duplications) can also show sperm production problems and infertility.

Microdeletions occur when very small pieces of the Y chromosome are missing. These problems cannot be detected through a routine chromosome analysis (karyotype). Microdeletions of the Y chromosome have been found in:

  • 2% or men with normal fertility
  • 7% of infertile men
  • 16% in men with azoospermia (no sperm in their ejaculate) or severe oligozoospermia (less than 1 million sperm)

To identify these microdeletions, special testing must be performed using a technology known as the polymerase chain reaction.

All chromosomes, including the Y chromosome, are divided into a “short arm” and a “long arm”.  Most deletions causing azoospermia or oligozoospermia occur in regions of the long arm known as the azoospermia factor (AZF) regions.  The AZF regions are further divided into

  • AZFa (proximal)
  • AZFb (central)
  • AZFc (distal)
Y chromosome

It appears that these regions, and possibly other regions of the Y chromosome, contain multiple genes necessary for normal sperm production. The specific location of the deletion along the Y chromosome and its size influences its effect on spermatogenesis.

AZFc Microdeletions

Men with microdeletions in the AZFc region have sperm production but they will commonly have very low sperm concentration while other men will not have any sperm visible in their ejaculate. However, areas of sperm production can still be found with a testicular biopsy. If testicular sperm are found, they can be used during IVF to fertilize eggs and produce pregnancies.

AZFa and AZFb Microdeletion

Men who have deletions involving the entire A2Fb region will rarely, if ever, have sperm in the ejaculate and doctors will rarely be able to find sperm with a testicular biopsy. The same may be true for men having deletions involving the entire A2Fa region of the Y chromosome.

What Is The Impact of The Father’s Y Chromosome Microdeletion On His Children?

Since daughters do not inherit a Y chromosome from their fathers, they will not have any fertility or health problems themselves. The sons, however, will inherit the abnormality and, therefore, may also have the same type of fertility problems as their fathers. What about other health issues? Unfortunately, there haven’t been a lot of studies on the children born to men with these microdeletions.  A study from 2011 found that some men with Y chromosome microdeletions also had abnormalities of another part of the Y chromosome (the pseudoautosomal regions or PARs). Abnormalities in one of the genes in this region, called the SHOX gene,  has been associated with short stature, mental retardation, and arm and wrist deformities. More work needs to be done in this area

Which Men Should Have Microdeletion Testing?

Men who have no sperm in their ejaculate which is not due to a known obstruction, should have Y chromosome microdeletion testing. In addition, men who have otherwise unexplained low sperm concentration (less than 1 million) should also be tested unless they have fathered children in the past without any fertility treatments.

Varicocele and Male Fertility and Infertility

Varicocele is the presence of enlarged or dilated veins in the blood vessels of the scrotum. Normally the scrotal veins have valves that regulate the blood flow. However, in some cases, the valves are absent or defective and the blood does not circulate out of the testicles efficiently. This results in swelling of the veins above and behind the testicles. 85% of varicoceles develop in the left testicle.

Varicocele

Varicocele and Infertility

It is estimated that varicoceles are present in about 20% of the normal fertile male population and up to 40% of an infertile population. It is clear, then, that the finding of a varicocele is not necessarily abnormal. At the present time, there is no way to determine whether a varicocele in an individual is the cause of infertility problems.

Scientists believe that at least some varicoceles are associated with infertility because they are found more commonly in infertile men. It is uncertain how varicoceles may cause infertility. Some evidence points to the increased temperature of the blood raising the temperature of the testes, which then damages the sperm. Heat can damage or destroy sperm. The increased temperature may also impede production of new, healthy sperm. Another theory is that in men with varicoceles, the testicular fluid which carries sperm has an increased concentration of chemicals which can damage sperm. The chemicals are called reactive oxygen species or ROS.

Varicocele Diagnosis

A varicocele may be detected on a physical exam. It is describes as looking or feeling like a “bag of worms”. It is more obviously seen or felt when a man is standing then when he is lying down. Sometimes, a varicocele may become more apparent when a man “bears down” to try to increase the intra-abdominal pressure.

The American Urological Association states that only varicoceles that can be felt have been documented to be associated with infertility. Not everyone agrees with that position. Scrotal ultrasound can be used to diagnose a smaller, less obvious varicocele. Echo color Doppler is a type of ultrasound that can measure blood flow in the veins of the scrotum.

Varicocele Treatment

Surgery

Most varicoceles can be corrected through a surgical procedure called varicocelectomy ( surgically “tying off” the affected veins). The following methods are used.

Surgical ligation

This procedure is performed under general anesthesia (the patient is asleep). In this procedure, a 2 to 3 inch incision is made in the groin or lower abdomen, the affected veins are identified and the surgeon cuts the veins and ties them off. This surgery can usually be performed on an outpatient basis. Full recovery takes about 6 weeks.

Laparoscopy

Laparoscopy is a technique in which a fiber optic telescope is inserted through the belly button into the abdominal cavity through a small incision. The surgeon can view what is happening by connecting a video camera to the laparoscope and watching a monitor. Once the varicocele has been located, the surgeon will introduce special instruments through small incisions near the pubic hair line to tie off the dilated veins. Most men can resume normal activities in a few two days.

Non-Surgical Methods

An alternative to tying off the veins is blocking the blood flow to the veins.

Embolization

Since embolization is a non-surgical procedure, it does not require general anesthesia but often the patient will be sedated. A small catheter is inserted into the veins just beneath the varicocele. A special dye is used to highlight the varicocele on x-ray and to visually guide the catheter. This is known as venography. Tiny coils are then advanced through the catheter to block the blood flow to the dilated veins. Most men can resume normal activities in a few two days.

Varicocele treatment with embolization coil

There is no evidence to suggest that any of these procedures work better than any other. However, the risks and recovery times are different.

There are two endpoints that are discussed after a varicocele repair: improvement in sperm counts and pregnancy. Unfortunately, many of the studies looking at varicocele repair have been poorly done. Consequently, there are mixed results as to whether more couples achieve pregnancy. There have been two well designed and well performed studies looking at varicocele repair. One study showed an improvement in pregnancy rates and one study did not.

Varicocele and In Vitro Fertilization – IVF and Intracytoplasmic Sperm Injection -ICSI

For couples in whom the men who have mild to moderately low numbers of moving sperm , intrauterine insemination (placing the sperm in the uterus) at the time of ovulation can be performed with reasonable success. For couples with any severity of sperm problems, in vitro Fertilization – IVF with intracytoplasmic sperm injection -ICSI is a highly effective method to achieve fertilization. Pregnancy rates are no longer dependent on the number of sperm but rather on female factors such as her age and response to fertility drugs.

Effects of male age on reproduction

In 1993, fathers aged <35 years accounted for 74% of live births within marriage, while only 25% of such births were to fathers aged 35–54 years. Ten years later, these percentages were 60% and 40%.  When the reproductive potential of older men is discussed, several celebrities who became fathers at advanced age such as Rod Stewart, Pablo Picasso, Charlie Chaplin, Warren Beatty, Tony Randall and Anthony Quinn are often cited as examples.

While the public regards these cases with a mixture of admiration and skepticism, birth statistics show that there are quite a number of children born to fathers aged >50 years in the general population and this is true of Eastern and Western cultures alike. However, it is well known that practically no children are born to mothers aged >50 years and it is common to all older fathers that they have younger partners.    

The effect of aging on the sperm

Semen is studied under the microscope. A typical semen analysis will evaluate a specimen for the total volume of the ejaculate, the number of sperm (concentration), the percentage of moving sperm (motility) and the percentage of sperm with a normal appearance (morphology). Studies have tried to determine if any of these semen parameters decrease over time. These are difficult studies to perform since many variables are present. The majority of studies seem to indicate that the volume of the ejaculate decreases with age as well as the percentage of moving sperm. There is no definite conclusion about whether the concentration of sperm or the microscopic appearance of the sperm (morphology) changes or not.

Age-dependent alterations of semen parameters may have several causes. In addition to age per se, factors such as infections, vascular diseases or an accumulation of toxic substances may be responsible for a deterioration in semen parameters. In a study of almost 4000 infertile men, researchers showed an infection rate in some of the reproductive  glands in 6.1% in patients aged <25 years but in 13.6% of patients >40 years. More importantly, total sperm counts were significantly lower in men with infections compared to those without.

Fertility of older men

Fertility has been documented scientifically in men up to an age of 94 years. If fertility in men decreases with age, it may in part be due to erectile dysfunction. In a large survey of Italian men, the frequency of erectile dysfunction rose from 4.6% in men <25 years to 37.6% in men >74 years. A history of cigarette smoking essentially doubled the risk of erectile dysfunction as men aged.

Several studies have been performed that tried to control for these and other variables in male fertility. For example, a study of birth rates in married couples in Ireland before the widespread use of contraception found that the probability of birth decreased for men starting from 42–43 years of age. Another study found that men >45 years old are 4.6-fold more likely to take over 1 year to get their partners pregnant relative to men aged < 25 years old.

With the use of fertility treatments , age related sperm problems may be bypassed. In fact, the more invasive the treatment, the less important male age appears to be. For example, several studies looking a the success rates of intrauterine insemination where sperm is injected directly into the uterus of a woman on the day of ovulation,  found an adverse impact of increased male age. On the other hand, several studies looking at the use of ICSI in which sperm is injected directly into an egg, did not find an effect of male age.  However, recently a group of researchers analyzed data from a German IVF registry from 1998 to 2002. They found a significantly reduced pregnancy rate in couples with male age >50 years and female age between 31 and 40 years, compared to couples with a male age <50 years. They suggest that this effect may have escaped the notice in previous studies because of a lower number of couples in this male age category.

There may also be an increase in the risk of miscarriage in older men. A recent study of over 5000 pregnant women in California concluded that the risk of miscarriage increased with increasing paternal age, and found that the association was stronger for miscarriages that happened in the first trimester. A study completed in 2002 found that the risk of miscarriage increased in older men but only when the women were also older.

Miscarriage risk according to father's age

This study suggests that for women under age 30, the age of the father does not increase the risk of miscarriage. Women who are aged 30 to 34 are at increased risk for miscarriage if the male is over age 40. Women who are over age 35 are at particularly high risk if their partners are over age 40. In this group, the risk for miscarriage was 6 times higher.

The causes for the increase in miscarriages with male aging is unknown. It is well known that the risk for chromosomal abnormalities in fetuses increases as women age and that these chromosomal abnormalities are responsible for the increase in miscarriage risk. No studies have ever found an increase in the rate of chromosomal abnormalities in fetuses with increasing male age however.

Risks to babies with older fathers

Women have all of the eggs they are ever going to have in their lives before they are born. The cells in the ovary which are destined to become eggs will go through several cell divisions and then stop. The eggs will then remain in this “off position” for the entire duration of a woman’s life until the egg is ovulated. It is this process that is thought to be responsible for the increased risk of chromosome abnormalities in eggs and embryos as women age. Men, on the other hand, produce sperm continuously all through their lives. The cells that produce sperm are constantly dividing during a man’s life. Every time a cell divides, the DNA must be exactly copied so that each “daughter cell” is identical to the “parent cell”. However, the more times a cell divides, the greater the chances for an error to be made when the DNA is being copied. These errors in DNA are called mutations.

It is possible, therefore, that older men may be at greater risk for having sperm with small errors (mutations) in the DNA and that these errors could cause certain diseases in the children of older men.

Risk of chromosome abnormalities

Two studies have found that older men have a greater risk for producing children with Down’s Syndrome (Trisomy 21).  In one study, men over age 40 were compared to men under age 25. The other study compared men 50 and older to men aged 25 to 29. Both studies found the risk for producing Down’s syndrome was higher.

Risk of genetic mutations

In August 2012, a study found that dads pass on an average of 25 new mutations at age 20, increasing to 65 mutations at age 40.   In the last several years, studies have focused on diseases caused be genetic mutations in the DNA and whether their is a relationship to the age of the father. Genetic diseases which are strongly thought to be related to the age of the father include:

  • Achondroplasia
  • Crouzon’s syndrome
  • Pfeiffer’s syndrome
  • Apert’s syndrome
  • Thanatophoric dysplasia
  • Osteogenesis imperfecta
  • Neurofibromatosis
  • Retinoblastoma

A Danish population based study of 1920 affected births of 1.5 million live births concluded that paternal age is associated with cleft lip and cleft palate, independently of maternal age. Single gene mutations are the suggested mechanism. Other diseases may have both a genetic and an environmental component and are referred to as complex or multi-factorial diseases. Some of these diseases have been identified as possibly occurring more commonly in older father.

  • Acute lymphoblastic leukemia
  • Congenital heart disease
  • Ventricular septal defect
  • Atrial septal defect
  • Alzheimer’s disease
  • Schizophrenia

A population based study of childhood brain cancers reported to the Swedish Cancer Registry between 1960 and 1994 concluded that there is a paternal age affect, estimated to confer about 25% excess risk in fathers >35 years of age.

Advanced paternal age has also been associated with increased risk of breast cancer and prostate cancer in their children.

Risk of Autism From Older Fathers

The cause of autism and related disorders (ASDs) is unknown; however, results from twin and family studies provide evidence for a strong genetic contribution. Environmental influences may also be important. The reported prevalence of ASDs has increased significantly during the past few decades. In this same period, the average age of men and women at the time of conception has also increased.  

The results of several large, well performed studies on the effects of parental age have yielded conflicting results. In an Australian population, one study found that increased female age, but not male age, was associated with autism. In a Danish population, a study found that the risk of autism was associated with increasing male age but not female age. A second Danish study reported no association between risk of autism and either male or female age. In April, 2007, the results of a large American study were published. This study concluded that both male and female age were associated with an increased risk of autism and related disorders even after adjusting for other factors. The older the parent, the greater the increase in risk.   In August, 2012, a study of families with an autistic child concluded that a father’s age could account for 15% to 30% of cases of autism due to the occurrence of new mutations the occur as men age.

Conclusion

Increasing male age may cause a decrease in fertility if the female is also older. The chance for miscarriage also seems to increase but the mechanism is not due to the most common reason for miscarriage which is numerical chromosome abnormalities. The overall impact of male age is far less than the impact of female age. Several diseases caused by gene mutations as well as several with multiple genetic and environmental causes are related to increasing paternal age. Despite these increased risks, the absolute risk of the diseases remains small.
