Background: GnRH analogs include agonists and antagonists that suppress gonadotropin secretion. Agonists (e.g., leuprolide, triptorelin, goserelin, histrelin) act as potent inhibitors of gonadotropin secretion when given continuously and cause downregulation of GnRH receptors with reduction of LH/FSH and suppression of ovarian and testicular sex steroid production; degarelix is a GnRH receptor antagonist that reduces gonadotropin release and testosterone.
