HCG Injections

Human Chorionic Gonadotropin (HCG)

HCG (Profasi, Pregnyl, Ovidrel ) induces the same effect that your natural LH surge provides --- the maturation and ovulation of the mature egg or eggs from the ovary.

It is administered when the follicles have reached the adequate size (18 - 20 mm) and the estradiol level is sufficient.

Appropriately-timed HCG injection ensures ovulation approximately 36-40 hours later, and enables perfectly timed intercourse or insemination.

HCG is also used during in vitro fertilization (IVF) cycles to mature the eggs prior to egg retrieval, which is then performed approximately 36 hours after the HCG injection. HCG can also be used for luteal support after IUI or egg retrieval in patients who do not have an excessive number of follicles. You may be instructed to take an additional injection of HCG one day after IUI and again, 3 days later. This will naturally encourage your own ovaries to make adequate levels of progesterone.
