Human chorionic gonadotropin (HCG) is a hormone that supports the normal development of an egg in a woman's ovary, and stimulates the release of the egg during ovulation. HCG is used to cause ovulation and to treat infertility in women, and to increase sperm count in men. HCG is also used in young boys when their testicles have not dropped down into the scrotum normally. This can be caused by a pituitary gland disorder. HCG may also be used for other purposes not listed in this medication guide.
Ovidrel is a hormone that is used to support the normal development of an egg in the ovary of a woman. This hormone also stimulates the release of an egg during ovulation. Ovidrel is given to women so that it can cause ovulation and to be able to treat infertility.
