Pregnancy occurs when the sperm and egg meet It takes the meeting of the sperm , which carries the X or Y chromosome, and the egg, which carries the X chromosome, for a pregnancy to occur. Sperm can stay viable for up to five days Although an egg will only survive for 24 hours, male sperm may stay alive and viable for up to five days after it has entered the woman's body, making it possible to conceive at almost any time. Out of the millions of sperm that are propelled into the woman's body with one ejaculation, only one sperm will penetrate the egg to fertilize it.
