Understanding Female Reproductive Hormones and the Menstrual Cycle

The video explains the roles of four key hormones in the menstrual cycle: estrogen, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). It describes how these hormones regulate the maturation and release of eggs, the buildup and maintenance of the uterus lining, and the process of menstruation. The video also covers the hormonal changes over the 28-day cycle, highlighting the secretion of FSH and estrogen, the LH surge triggering ovulation, and the role of progesterone in maintaining the uterus lining. If fertilization does not occur, progesterone levels drop, leading to menstruation.
