pregnancy only occurs if intercourse occurs within the 6 days prior to and including ovulation. Intercourse after the day of ovulation does not result in pregnancy. The probability of conception ranged from 10% when intercourse occurred five days before ovulation to 33% when it occurred on the day of ovulation itself.

This is the data that suggests the best timing of intercourse in order to conceive is day 10, 12, 14 and 16 (in case of late ovulation) of a 28 day cycle or days -4, -2, 0, +2 in relation to expected ovulation in the case of cycles different than 28 days.

Can Timing of Intercourse Influence Gender Outcome?


The Chinese Conception Chart - or Chinese Gender Chart - was discovered in a royal tomb over 700 years ago. According to legend, the chart is capable of predicting the gender of an unborn child based on two variables: the baby's month of conception and the mother's age.

On the chart below, predict gender by cross-referencing the age of the mother at the time of conception with the month the baby was conceived. For example, if you were 35 years old at the time of conception and your baby was conceived in August, the chart predicts you'll have a girl.

It is claimed that this ancient method is highly accurate - but no clinical studies have verified this: Have fun!

The most fertile period (the time with the highest likelihood of pregnancy resulting from sexual intercourse) covers the time from some 5 days before ovulation until 1–2 days after ovulation. In an average 28 day cycle with a 14-day luteal phase, this corresponds to the second and the beginning of the third week of the cycle. considering d 1st day of menstruation as DAY 1. If you want to conceive, the most fertile time occurs between 19 and 10 days prior to the expected menses.
