Background. Gonadotropin-releasing hormone (GnRH) is a neurohormone central to initiation of the reproductive hormone cascade. Pulsatile secretion of GnRH from the hypothalamus is key in establishing and maintaining normal gonadal function.onadotropin-releasing hormone and gonadotropin-releasing hormone receptors. The decapeptide GnRH is derived from posttranslation processing of a tripartite 92âamino acid (AA) pre-pro-GnRH. The first 23 AA is a signal peptide and the last 56 AA is known as GnRHâassociated protein (GAP).
