Ovulation occurs seven days after intercourse.

So, what is ovulation? It refers to the release of an egg from a woman's ovary within seven days of sexual intercourse. During this day, a woman's vagina becomes moister and the eggs are more easily attracted to sperm. If fertilization occurs at this time, the fertilized egg will implant in the ovary and begin to develop into a fetus.

However, while ovulation is important, not all sexual activity is appropriate during this time. Because if you have sex during the ovulation period, the fertilized egg may not have enough time to reach the uterus and implant, resulting in contraceptive failure. Therefore, if you want to avoid pregnancy, it's best to use oral or injectable birth control within seventy-two hours of having sex, rather than having sex during ovulation.

In addition to ovulation, there are other factors that can affect a woman's fertility. For example, if women have erratic menstrual cycles, they may be less fertile. In addition, if women have poor health conditions, such as inflammation or tumors, it can also affect their fertility. Therefore, if you want to improve women's fertility, you should pay attention to their health and have regular check-ups.
