Definitions for "GnRH agonists"
Fertility drugs used to prevent the pituitary gland from releasing FSH and LH hormones. FSH and LH aid in normal ovulation, but may interfere with assisted reproductive treatments. Lupron, Synarel, and Zoladex are GnRH agonists used in the U.S.
A group of medicines used to treat endometriosis. GnRH agonists block the release of GnRH from the brain. GnRH is normally released by the brain, which in turn stimulates the release of FSH (follicle stimulating hormone) which acts on the ovaries to stimulate egg production and estrogen production. GnRH have the effect of putting women through a temporary menopause by turning off the estrogen production by the ovary.
A group of drugs that suppress the pituitary gland (the gland that produces hormones that regulate the function of the ovaries).
