a hormone (see gonadotrophin) synthesized and released by the anterior pituitary gland. FSH stimulates ripening of the follicles in the ovary and formation of sperm in the testes. It is administered by injection to treat sterility due to lack of ovulation, amenorrhoea, and decreased sperm production. Stimulation of ovulation by FSH may, in some cases, lead to multiple pregnancy.
