Sperm
Male reproductive cells that can fertilize an egg. Sperm can survive in the female reproductive tract for up to 5 days.
Detailed Explanation
Sperm are the male reproductive cells needed to fertilize an egg. An important fact for emergency contraception: sperm can survive inside the female reproductive tract for up to 5 days. This means unprotected sex several days before ovulation can still result in pregnancy, as the sperm can wait for the egg. This is why the timing of EC relative to ovulation—not just to intercourse—matters for effectiveness.
