The menstrual cycle covers the coordinated changes in the ovaries and uterus, including menstruation, follicular growth, ovulation and corpus luteum formation. It links follicle-stimulating hormone, luteinizing hormone, oestrogen and progesterone with endometrial changes, and distinguishes the ovarian cycle from the uterine cycle and the hormonal events of pregnancy.
