If the egg is not fertilized, it lives for about one day. In the absence of fertilization, the uterus undergoes changes to prepare for the possibility of a fertilized egg, thickening its lining each month.
If the egg is not fertilized during a woman’s menstrual cycle, it undergoes degeneration and is expelled from the body along with the uterine lining during menstruation. The unfertilized egg has a lifespan of about 12 to 24 hours after ovulation. If no sperm fertilizes the egg during this timeframe, hormonal changes signal the body to disintegrate the egg and shed the uterine lining. The process prepares the reproductive system for a new cycle, with the release of another egg and the potential for fertilization in the following month.
