Answer

The menstrual cycle is an orderly progression of coordinated hormonal events in the female body that stimulates growth of a follicle to release an egg and prepare a site for implantation if fertilization should occur. Menstruation occurs when an egg released by the ovary remains unfertilized; subsequently, the soggy decidua of the endometrium (which was primed to receive a fertilized egg) is sloughed in a flow of menses in preparation for another cycle.
