Question

Quizplus · Accepted Answer

Gonadotropin-releasing hormone (GnRH) is a hormone that is secreted directly from the hypothalamus in the brain. It regulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which in turn stimulates the production of sex hormones such as testosterone, estradiol, and progesterone in the gonads (testes and ovaries).
