- . It is thought that the human ovum can be fertilized no later than 24 to 48 hours after it is extruded from the ovary. Although motile sperm have been recovered from the uterus and the oviducts as long as 60 hours after coitus, their ability to fertilize the ovum probably lasts no longer than 24 to 48 hours. Pregnancy is unlikely to occur if a couple refrains from intercourse for 4 days before, and for 3 or 4 days after, ovulation (fertile period) Unprotected intercourse on the other days of the cycle (safe period) should not result in pregnancy. Ovultation usually occurs about 14days (12 to 16) before the onset of menstruation
