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.
