The fertile window is the period during a menstrual cycle when pregnancy is most likely to occur. This window usually includes the five days before ovulation, the day of ovulation itself, and the day after ovulation.
Sperm can survive inside the female reproductive tract for up to five days, while the egg remains viable for about 12–24 hours after ovulation. Because of this biological timing, intercourse during the fertile window significantly increases the chances of conception.
How Ovulation Affects Fertility
Ovulation is the release of a mature egg from the ovary. In many women with a regular cycle, ovulation occurs about 14 days before the next menstrual period begins.
However, ovulation timing can vary from cycle to cycle depending on hormonal fluctuations, stress levels, and lifestyle factors.
Why Fertility Tracking Is Helpful
Tracking fertile days helps couples plan pregnancy more effectively and improves awareness of reproductive health patterns.
Fertility tracking tools should be used for educational purposes and do not guarantee pregnancy outcomes.
