LH-RH
Definition
A hormone made by a part of the brain called the hypothalamus. LH-RH causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In men, these hormones cause the testicles to make testosterone. In women, they cause the ovaries to make estrogen and progesterone. Also called GnRH, gonadotropin-releasing hormone, LHRH, and luteinizing hormone-releasing hormone.
