Gonadotropin-releasing hormone (GnRH) is a releasing hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is a tropic peptide hormone synthesized and released from GnRH neurons within the hypothalamus. The … See more The identity of GnRH was clarified by the 1977 Nobel Laureates Roger Guillemin and Andrew V. Schally: As is standard for peptide representation, the sequence is given from amino terminus to … See more The gene, GNRH1, for the GnRH precursor is located on chromosome 8. In mammals, the linear decapeptide end-product is synthesized from an 89-amino acid See more GnRH production/release is one of the few confirmed examples of behavior influencing hormones, rather than the other way around. Cichlid fish that become socially dominant in turn experience an upregulation of GnRH secretion whereas cichlid fish that are … See more GnRH activity influences a variety of sexual behaviors. Increased levels of GnRH facilitate sexual displays and behavior in … See more GnRH is secreted in the hypophysial portal bloodstream at the median eminence. The portal blood carries the GnRH to the pituitary gland, which contains the gonadotrope cells, … See more Natural GnRH was previously prescribed as gonadorelin hydrochloride (Factrel) and gonadorelin diacetate tetrahydrate (Cystorelin) for use in treating human diseases. Modifications of the decapeptide structure of GnRH to increase half life have led to See more The natural hormone is also used in veterinary medicine as a treatment for cattle with cystic ovarian disease.
