Question

How much sperm can cause you to become pregnant?

Answer

It only takes one sperm cell uniting with an egg to cause pregnancy. A healthy male releases about 500,000,000 sperm with each ejaculation. While only one is needed, the large number increases the odds that at least one will reach the egg. It should also be kept in mind that sperm can live over six days inside a woman's body, so even if sex does not take place on the day your egg is released, you still can become pregnant from leftover sperm.
