Gonadotropin-Releasing Hormone (GnRH): Purpose

WebGonadotrophin-releasing hormone is produced and secreted by specialised nerve cells in the hypothalamus of the brain. It is released into tiny blood vessels that carry this hormone from the brain to the pituitary gland, where it stimulates the production of two more hormones – follicle stimulating hormone and luteinising hormone. ley lines map new mexico https://magnoliathreadcompany.com
