The menstrual cycle is divided into several phases:
1. Menstrual Phase: Shedding of the uterine lining. 2. Follicular Phase: Follicle-stimulating hormone (FSH) promotes the maturation of ovarian follicles. 3. Ovulation: A mature egg is released from the ovary. 4. Luteal Phase: The corpus luteum forms, secreting progesterone to maintain the uterine lining for potential pregnancy.
