Detailed explanation-1: -A hormone made by a part of the brain called the hypothalamus. Gonadotropin-releasing hormone causes the pituitary gland in the brain to make and secrete the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Detailed explanation-2: -Gonadotropin hormone-releasing hormone (GnRH) is the key regulator of the reproductive axis. Its pulsatile secretion determines the pattern of secretion of the gonadotropins follicle stimulating hormone and luteinizing hormone, which then regulate both the endocrine function and gamete maturation in the gonads.
Detailed explanation-3: -Gonadotrophin-releasing hormone is produced and secreted by specialised nerve cells in the hypothalamus of the brain.
Detailed explanation-4: -A key area for production of GnRH is the preoptic area of the hypothalamus, which contains most of the GnRH-secreting neurons.
