Ovulation: The monthly release of an egg from an ovary. This usually happens 14 days before the beginning of your period (menstrual flow). When the egg is released, it travels through the fallopian tube, where it could become fertilized by a sperm. If it is fertilized, it attaches to the wall of the uterus (womb) for development and growth. If it's not fertilized, the egg passes out of the body with the menstrual flow.
