Semen analysis and sperm motility
The determination of the number os sperm that are moving rapdily in a forward progressive manner is of paramount importance in the evaluation of male fertility.
In an average semen analysis, there will be some sperm with no movement, some that are moving slowly and/or some that do not move in a forward direction. These sperm are less likely to be able to produce a pregnancy easily.
With computerized semen analysis, the computer identifies and tracks every sperm seen in under the microscopic field. Over a fraction of a second, the path the sperm has traveled is analyzed and many different parameters can then be computed with a high degree of accuracy.
In the picture below, the sqigly green lines are the paths of individual sperm. The red dots mark sperm that are not moving.
Some of the parameters that are calculated include:
Here is what a sample report looks like: male infertility test, male infertility tests, male fertility, male infertility, male fertility test, sperm, sperm counts, low sperm counts, increase sperm counts, normal sperm count, sperm concentration, sperm motility, sperm morphology, semen analysis
Medical studies have evaluated these parameters individually and have found that many are independent predictors for male fertility. In other words, it is now possible to identify men with fertility problems even though their standard semen analysis may seem completely normal.
