The chances of pregnancy are usually particularly low, if not non-existent, when a man ejaculates for the first time during intercourse and then continues to have intercourse a second time without a condom, if the interval is more than four hours or more. However, if the first ejaculation is followed by intercourse an hour apart without any contraception, it may result in a woman’s pregnancy even if there is no ejaculation. This is because a man may have a small amount of sperm left on his penis after ejaculation. Therefore, if the interval is short, the sperm may enter the woman’s uterine tubes during the second intercourse and combine with the egg to cause pregnancy. For women who have no requirement for reproduction, it is best to consider taking emergency contraceptive pills as a remedy.
