Menstruation is regulated by a delicate balance of hormones. Here are the key players and their roles:
1. Follicle-Stimulating Hormone (FSH): Produced by the pituitary gland, FSH stimulates the growth of ovarian follicles, each containing an egg.
2. Luteinizing Hormone (LH): Also from the pituitary gland, LH surges mid-cycle, triggering ovulation—the release of a mature egg from the ovary.
3. Estrogen: Produced by the growing follicles, estrogen helps thicken the uterine lining in preparation for a potential pregnancy.
4. Progesterone: After ovulation, the corpus luteum (what remains of the follicle) secretes progesterone, maintaining the uterine lining. If pregnancy doesn’t occur, progesterone levels fall, leading to menstruation.
5. Gonadotropin-Releasing Hormone (GnRH): Produced by the hypothalamus, GnRH stimulates the pituitary gland to release FSH and LH.
These hormones work in concert to regulate the menstrual cycle.
