Fertilization is most likely to occur when intercourse occurs ____.

Question

Quizplus · Accepted Answer

Fertilization is most likely to occur when intercourse occurs within the 2 days before and on the day of ovulation because sperm can survive in the female reproductive tract for up to 5 days, and the ovum can survive for up to 24 hours after ovulation. Therefore, the most fertile period is the 4-5 day window leading up to and including the day of ovulation. Intercourse 2 days after ovulation is less likely to result in fertilization as the ovum will have already disintegrated by then. Intercourse 5 days after ovulation or any time beyond 1 week after ovulation is highly unlikely to result in fertilization.
