Sperm gets ejected from the penis, enters the vagina, and swims up the reproductive tract until they reach the egg to fertilize it. Barely years ago, it was considered a major scientific breakthrough when scientists came up with the idea that a fully formed, tiny human inhabited the head of each sperm — totally debunked and untrue. Fortunately, as the human body has evolved over thousands of years to maximize fertility potential, so has our scientific understanding about sperm. But many of us still believe some pretty unscientific, long-standing sperm myths. Here are twelve of the most common ones.
Pregnancy and wiping sperm in the vagina: What to know
Semen has controlling power over female genes and behaviour | New Scientist
By Michael Le Page. In many animals, seminal fluid alters both the bodies and sometimes even the behaviour of females. Human semen, too, triggers changes in the uterus, and might have wider effects on women, aimed at just one goal. The effects are most striking in fruit flies: seminal fluid can make the females eat more, lay more eggs and be less receptive to other males. Now a team led by Tracey Chapman at the University of East Anglia in Norwich, UK, has found that male fruit flies selectively alter the chemical make-up of their seminal fluid. In the presence of rivals, the males produce more seminal proteins.
Getting sperm out of the body after sex: Is it possible?
Back to Pregnancy. Yes, although the risk of getting pregnant in this way is very low. If you want to avoid getting pregnant, you should use contraception.

Some people may wish to remove semen from the vagina after sex, either for hygienic reasons or to try to prevent pregnancy. However, once semen enters the cervix through the vaginal canal, there is no scientifically proven way to remove it. There are a few ways to clean the vagina and the areas around it safely. However, if someone wishes to avoid becoming pregnant, they should seek appropriate medical advice. In this article, we look at how to clean the vagina after sex and how effective this is in removing semen.
