Patient's question:
NoDoctor's answer:
Within 6 hours after an egg is released from the ovary, its fertilization ability is strongest and can be maintained for about 30 hours. After that, the egg begins to degenerate, and its fertilization ability rapidly declines and disappears. In principle, only one egg is produced by one ovary each month. If it encounters sperm, it will lose its ability to conceive and die.
