GnRH hormone secreted by the hypothalamus controls the ovarian and uterine cycles.
The hypothalamus gland in your brain produces and releases GnRH into your blood vessels through nerve cells, or neurons. The pituitary gland, located near the base of the brain, receives the hormone after that. The production and release of follicle-stimulating hormone (FSH) and luteinizing hormone are stimulated by GnRH. Hormones regulate the ovarian and uterine cycles.
The hypothalamus secretes gonadotropin releasing hormone (GnRH), which prompts the anterior pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The anterior pituitary starts to secrete more follicle-stimulating hormone (FSH) and luteinizing hormone a few days before the start of the ovarian cycle (LH).
