GnRH activity influences a variety of sexual behaviors. Increased levels of GnRH facilitate sexual displays and behavior in females. GnRH injections enhance copulation solicitation (a type of courtship display) in white-crowned sparrows. In mammals, GnRH injections facilitate sexual behavior of female display behaviors as shown with the musk shrew’s (Suncus murinus) reduced latency in displaying rump presents and tail wagging towards males. WebGonadotropin-releasing hormone (GnRH) is a decapeptide (Fig. 1) produced in the hypothalamus. It is also known as luteinizing hormone-releasing hormone (LHRH), gonadoliberin, luliberin, gonadorelin, and GnRH I. Despite various functions reported for GnRH in mammals, biochemical, molecular, neuroanatomical, pharmacological, and …

WebAbstract. The hypothalamic decapeptide gonadotrophin-releasing hormone (GnRH) binds to specific receptors on pituitary gonadotrophs. These receptors belong to the family of G protein-coupled receptors. Their activation leads to phosphoinositide breakdown with generation of inositol 1,4,5-trisphosphate (Ins (1,4,5)P3) and diacylglycerol. WebIn the last decade, much has been learned about the physiology and cellular biology of GnRH. In addition more than 2000 analogs agonists and antagonists have been synthesized.
