Question: how long should sperm stay inside a woman to get pregnant?
Answer: The best time to get pregnant For pregnancy to happen, the egg must be fertilised by a sperm within this time. Sperm can live for up to 7 days inside a woman's body. So if you've had sex in the days before ovulation, the sperm will have had time to travel up the fallopian tubes to "wait" for the egg to be released.
