Human chorionic gonadotropin (HCG) is a hormone that maintains the normal development of the ovum in the ovary of a woman, and stimulates the release of the oocyte during ovulation.
HCG is used to cause ovulation and to treat infertility in women, and to increase the number of sperm in men. HCG is also used in young boys when their testicles do not fall down into the scrotum normally. This can be caused by a pituitary gland disorder.
Human chorionic gonadotropin HCG – has gonadotropic, mainly luteinizing effect. In men, it stimulates interstitial cells of the gonads, primarily Leydig cells, thereby enhancing testosterone synthesis and partially spermatogenesis, activating the development of genital organs and secondary sexual characteristics.
