How many days can sperm survive in a woman?

Many people will ask how long the sperm will survive in the female body after a sexual life. Under normal circumstances, if it is healthy sperm, it can survive in the female body for 48-72 hours after sexual life, that is, if 48 hours or 72 hours just catch up with female ovulation, there is also the possibility of conception during this period. Therefore, it is very unsafe to adopt safe contraception. If there happens to be accidental ovulation, sperm and eggs may eventually combine to form fertilized eggs while sperm are still viable, which is one of the main reasons for many unwanted pregnancies.
