Which hormone is involved in the ovarian response to GnRH from the hypothalamus?

The hormone that plays a crucial role in the ovarian response to GnRH (Gonadotropin-releasing hormone) from the hypothalamus is Follicle Stimulating Hormone (FSH). GnRH stimulates the anterior pituitary gland to release FSH and Luteinizing Hormone (LH), which are essential for the regulation of the menstrual cycle and ovarian function.

FSH specifically fosters the growth and maturation of ovarian follicles during the follicular phase of the menstrual cycle. It acts on the granulosa cells of the ovarian follicles, promoting the development of eggs and the production of estrogen. This hormone is vital for reproductive health and plays a significant role in ovarian follicle development, making it an integral component of the hormonal signaling initiated by GnRH.

Understanding the function of FSH provides insight into its critical position in the reproductive axis and how it interacts with other hormones to facilitate the processes necessary for ovulation and fertility.
