The human egg reaches the ampullary part of the Fallopian tube within 2-3 minutes of being released from the ovary. If fertilization (penetration of the egg by a sperm) does not occur within 24 hours, the egg starts to decay. The sperm takes a few minutes to reach the Fallopian tube after it is deposited in the cervix. Although the sperm lives up to 7 days, its ability to penetrate the egg only lasts for about 72 hours. So, to maximize the chance of fertilization, the sperm should already be present in the ampullary area of the Fallopian tube. In a 28 day menstrual cycle, most women will ovulate around day 14. Hence, it can be inferred that the maximum chance of fertilization will occur, if the sexual intercourse takes place about 24 hours preceding ovulation.
