Gonadorelin (Intravenous route, injection route)
Gonadotropin Releasing Hormone Agonist
Uses of This Medicine:
Gonadorelin is a medicine that is the same as gonadotropin-releasing hormone (GnRH) that is naturally released from the hypothalamus gland. GnRH causes the pituitary gland to release other hormones (luteinizing hormone [LH] and follicle-stimulating hormone [FSH]). LH and FSH control development in children and fertility in adults.
Gonadorelin is used to test how well the hypothalamus and the pituitary glands are working. It is also used to cause ovulation (release of an egg from the ovary) in women who do not have regular ovulation and menstrual periods because the hypothalamus gland does not release enough GnRH.
Gonadorelin may also be used for other conditions as determined by your doctor.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although not specifically included in product labeling, gonadorelin is used in certain patients with the following medical conditions:
