The menstrual cycle comprises four sequential phases: Menstruation: Uterine lining (endometrium) is shed. Follicular phase: Ovarian follicles develop, stimulated by follicle-stimulating hormone (FSH). Ovulation: A mature egg is released from the ovary, prompted by a luteinizing hormone (LH) surge. Luteal phase: The corpus luteum forms, producing progesterone to prepare the uterus for potential implantation.The chronological order is Menstruation, Follicular phase, Ovulation, Luteal phase.
