Patient's question:
I really enjoy having sex with my boyfriend. I had sex with him just one day after my ovulation, and I didn't use any protection. I'm very worried about getting pregnant as a result, so I want to know how long an egg survives after ovulation.What kind of help do I need: How long does an egg survive after ovulation?
Doctor's answer:
Problem Analysis: Hello, the egg generally survives for 24 ± 6 hours after ovulation. Within 12 hours after ovulation, the egg has the strongest fertilization ability. It still has fertilization ability between 15-18 hours. After 24 hours, the fertilization ability is lost. After normal ejaculation, sperm can survive in the uterine cavity for 2-3 days, but its reproductive ability only lasts for 1-2 days. Sperm that stays in the vagina instead of entering the uterine cavity survives for no more than 24 hours. Therefore, the fertilization time should be within 24 hours after ovulation. Hope this helps.
