Varies: The sperm can fertilize an egg within an hour of having sex if the egg is available (ie: ovulation has occurred). If the woman has not ovulated yet, the sperm could live for up to 6 days inside her and still be able to fertilize an egg when ovulation does happen. It would take about 10 days for a pregnancy test to be positive after conception.
