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.
GnRH signals the pituitary gland to release two puberty hormones into the bloodstream: FSH and luteinizing hormone (LH). Doctors often order a test for LH when ordering a blood test for FSH. In boys, FSH and LH work together to get the testes to begin producing testosterone, the hormone responsible for the physical changes of puberty and the production of sperm.
