Semen contains millions of sperm cells. The sperm in the male’s semen, which normally empties into the vagina, moves to the uterus. Sperms can survive in the vagina and uterus for up to 5 days. They then come into contact with the ovular and ensure fertilization.
When the semen gets around the vagina, it is assumed that pregnancy will not occur, but this is not entirely true. Sperm cells that spread around the vagina continue to maintain their vitality and can reach the ovular by moving through the vagina into the uterus. In this case, pregnancy may occur. In other words, semen contamination in the vagina can cause pregnancy.
Even if the male does not discharge into the vagina during sexual intercourse, the semen around the vagina may somehow reach into the uterus, so the semen should be wiped with a wet wipe and then washed thoroughly. This will eliminate the risk of getting pregnant. Regardless, one of the best ways of contraception is to use condoms.
