How does this medication work? What will it do for me?
Cetrorelix belongs to the class of medications called GnRH antagonists. Cetrorelix is used to prevent premature ovulation in women undergoing ovarian stimulation. It blocks the effects of gonadotropin-releasing hormone (GnRH). GnRH controls the secretion of another hormone, called luteinizing hormone (LH), a hormone that starts ovulation (release of an egg) during the menstrual cycle. Cetrorelix allows the release of an egg to be controlled so it is released at the best time for pregnancy to occur.
