Ganirelix belongs to the class of medications known as gonadotropin-releasing hormone (GnRH) antagonists. It is used to prevent premature ovulation in women undergoing ovarian stimulation as part of fertility treatment. 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. Ganirelix allows the release of an egg to be controlled so it is released at the best time for pregnancy to occur.
