Ovulation Date

The graph below depicts what a woman’s probability of conception is on the days before, during, and after the date of ovulation. It may be surprising to find that the highest probability of conception occurs with intercourse on the days before ovulation, rather than the ovulation date.^2,3

According to a 2001 report in Statistics in Medicine, the ovulation date holds only a 5% chance of conception, but the four days before hold a cumulative 80% chance of conceiving.3 These new findings demonstrate that a woman’s highest probability of conception is on the 4-5 days before ovulation. This time period is commonly called the fertility window.

Ovulation Date & the Fertility Window

The Fertility Window is the time period during your monthly menstrual cycle in during which sexual intercourse can lead to a conception. That is the 4 days before ovulation and ovulation date. In studies that were conducted at university based hospitals, it has been shown that the probability of conception is highest on the 4 days before ovulation, as sperm can remain alive inside a woman's body for at least 5 days4. In fact, in some rare circumstances they may even stay alive for as long as 6 or 7 days. Through the identification of the Fertility Window, you have defined a maximal period of time available to you whereby you and your partner can plan multiple attempts to conceive during the cycle. In this way, your cumulative probability of a successful conception can be maximized. By having intercourse during the 4 days before pregnancy, you can double your chances of pregnancy.
