Ovulation

Ovulation is when a mature egg is released from the ovary, pushed down the fallopian tube, and is available to be fertilized. Approximately every month an egg will mature within one of your ovaries. Ovulation is the release of egg from the ovaries. In humans, this event occurs when the de Graaf's follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. In addition, the uterine lining (endometrium) is thickened to be able to receive a fertilized egg. If no conception occurs, the uterine lining as well as blood will be shed during menstruation.
