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).
