Definition: Ovulation

Ovulation is defined as the event of de Graaf's follicles rupturing and releasing secondary oocyte ovarian cells. It is the phase of a female's menstrual cycle when an egg (ovule) is released from the ovaries. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm. Concomitantly, 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. In humans, ovulation occurs about midway through the menstrual cycle, after the follicular phase. The few days surrounding ovulation (from approximately days 10 to 18 of a 28 day cycle), constitute the most fertile phase. The time from the beginning of the last menstrual period (LMP) until ovulation is, on average, 14.6 days, but with substantial variation between women and between cycles in any single woman, with an overall 95% prediction interval of 8.2 to 20.5 days.
