In general, the time around ovulation is considered the best time to get pregnant. The female egg is only capable of being fertilised for 12 to 24 hours. The male sperm, on the other hand, can survive in the uterus for a few days.
Not all days around ovulation are equally suitable to get pregnant. The most fertile days for women are mainly on the day BEFORE and on the day OF ovulation. After ovulation, the pregnancy rate drops significantly.
One study has looked at how high the probability of pregnancy is, depending on ovulation, on the various days before and after ovulation. The test subjects who were trying to get pregnant were checked regularly in order to determine the ovulation date as precisely as possible. Sexual intercourse took place only once during the fertile phase. The result of this study was that the closer sexual intercourse takes place to ovulation, the greater the chance of becoming pregnant.
Frequent sexual intercourse (every 2 days) increases the rate of pregnancy, daily sexual intercourse does not have a negative effect.
The Kinderwunch Institut Dr Loimer can help you find the optimal time of intercourse for you. The prerequisites for a positive outcome of cycle monitoring are of course open fallopian tubes in the woman and good quality semen.
In summary, we can say that the best pregnancy rates are achieved when the couple has intercourse the day before or the day of ovulation.
