Gonadotropin is a hormone produced by the pituitary gland that stimulates the reproductive organs. There are several synonyms for this hormone, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH is responsible for triggering ovulation in females and stimulating testosterone production in males. FSH, on the other hand, stimulates the growth and maturation of ovarian follicles in females and the production of sperm in males. Human chorionic gonadotropin (HCG) is another hormone that is closely related to gonadotropin. HCG is produced during pregnancy and plays a vital role in supporting the developing fetus. These hormones play a crucial role in the reproductive system of both males and females.
