I'm confused; i have some doctors saying that sperm is only active for 48 to 72 hours then saying that someone can get pregnant 5 days before ovulation?

Pregnancy sperm: You are informed relatively corrected that sperm survived about 3 days( 72hrs) and eggs about one or two days. And pregnancy is extremely unlikely if after 5 days which by statistic as an old egg that probably explained those failed succeessful pregnancy or abortive pregnancies. To try to get pregnant at the optimal time is essential for healthy pregnancy. Good luck, .
