A small amount of sperm remains during ovulation

These small amounts of sperm may survive in a woman's body for a period of time and combine with an egg cell to form a fertilized egg in the following days. This condition is very common during sexual intercourse, and the establishment of a fertilized egg is one of the keys to fertility.

While leaving behind a small amount of sperm may increase your chances of getting pregnant, it's not an ideal way to have a baby. If a woman is in a risk period and sperm enters the vagina, the likelihood of pregnancy is higher. In addition, even if only a small amount of sperm enters the vagina, they can penetrate numerous defenses and eventually reach the fallopian tube, where they combine with egg cells to form fertilized eggs.

Therefore, it is important for any couple trying to have a baby to ensure that sex is safe and responsible. Before choosing when, how, and with whom to have sex, you should carefully consider your own and your partner's needs and risks.
