Gonadotropin-releasing hormone (GnRH) Written By: Gonadotropin-releasing hormone (GnRH), also known as luteinizing hormone-releasing hormone, a neurohormone consisting of 10 amino acids that is produced in the arcuate nuclei of the hypothalamus. GnRH stimulates the synthesis and secretion of the two gonadotropinsâluteinizing hormone (LH) and follicle-stimulating hormone (FSH)âby the anterior pituitary gland.
1 Stimulation of growth hormone secretion: Ghrelin, as the ligand for the growth hormone secretagogue receptor, potently stimulates secretion of growth hormone. 2  The ghrelin signal is integrated with that of growth hormone releasing hormone and somatostatin to control the timing and magnitude of growth hormone secretion.
