The menstrual cycle is regulated by a complex interplay of hormones, but four key hormones play major roles in this process:
1. Follicle-Stimulating Hormone (FSH): FSH is produced by the anterior pituitary gland. It stimulates the growth and development of follicles (small sacs in the ovaries) that contain immature eggs.
2. Luteinizing Hormone (LH): LH, also produced by the anterior pituitary gland, triggers ovulation. It causes the mature follicle to release an egg from the ovary.
3. Estrogen: Estrogen is primarily produced by the growing follicles in the ovaries. It helps stimulate the thickening of the uterine lining (endometrium) in preparation for possible pregnancy and is involved in the development of secondary sexual characteristics.
4. Progesterone: Progesterone is mainly produced by the corpus luteum, a structure formed from the empty follicle after ovulation. It helps maintain the uterine lining and prepares it for potential embryo implantation. If pregnancy doesn't occur, progesterone levels drop, leading to menstruation.
These hormones work together in a carefully coordinated manner to regulate the menstrual cycle, which typically lasts around 28 days, although it can vary from person to person.
The menstrual cycle is regulated by the complex interaction of hormones: luteinizing hormone, follicle-stimulating hormone, and the female sex hormones estrogen and progesterone. The menstrual cycle has three phases: Follicular (before release of the egg) Ovulatory (egg release)
