Eggs that are not fertilized will atresia, die, and either pass out of the body or be absorbed by the peritoneum. Normal women of childbearing age have two ovaries, which normally ovulate in turn each month. After ovulation, the egg is picked up by the umbilical end of the fallopian tube and transported to the juxtaposition of the fallopian tube, where it waits for sperm to fertilize it, and most of the eggs will survive for 48 hours. Most of the eggs can survive for 48 hours. If the egg cannot meet the sperm to form a fertilized egg, it will be atretic and die. Most of the dead eggs will be sent to the uterus and flow out of the body with the woman’s menstruation, and some of the eggs that are not fertilized may fall into the abdominal cavity, be absorbed by the organs of the peritoneum, and then metabolically utilized through phagocytosis by the macrophage or be discharged out of the body. The unfertilized eggs do not need any special treatment and will go through the process of regulation by themselves.
