(January 2013). Gonadotropin-releasing hormone (GnRH), also known as luteinizing hormone-releasing hormone (LHRH) and luliberin, as well as gonadorelin (INN), is a trophic peptide hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.nRH is found in organs outside of the hypothalamus and pituitary, and its role in other life processes is poorly understood. For instance, there is likely to be a role for GnRH1 in the placenta and in the gonads. GnRH and GnRH receptors are also found in cancers of the breast, ovary, prostate, and endometrium.
