In the proper environment, such as the female reproductive tract beyond the cervix, sperm have a life-span of up to five days. In other environments, such as the vagina, sperm live only a few hours and even less than that outside the human body, exposed to the open air. The egg, on the other hand, has a life-span of only about twenty-four hours from the time it bursts from the ovary. So, fertilization can occur anytime live sperm meet up with a live egg, which can happen even if the sperm are deposited up to five days in advance of ovulation.
