Ovulation calendar

All content is checked by medical journalists.

The ovulation calendar calculates when a woman is most likely to ovulate. Why is it important? According to the rule of thumb, the five days before, the day of ovulation itself and the day after are considered fertile days - this is the time during which the chances of getting pregnant are greatest. However, ovulation calculators are unsuitable as a method of contraception. However, an ovulation calendar gives couples who want to have children an indication of when sex is most likely to lead to "success". Read more about it!

When ovulating, a mature egg cell detaches itself from the ovary and makes its way through the fallopian tube towards the uterus. After ovulation, sperm have around 24 hours to fertilize the egg. Since sperm cells can survive in the female body for five days or more, the days before ovulation are also fertile days.

Statistical Probabilities

In theory, ovulation occurs in the middle of the menstrual cycle. In fact, no female body adheres to a fixed circuit diagram. Ovulation can therefore take place much earlier, later or not at all.

The ovulation calculator calculates the fertile days according to statistical probabilities, so at best it can roughly narrow down the period. The more irregular a woman's cycle, the more uncertain the calculated fertility calendar is.

Methods that indirectly detect ovulation are more reliable than an ovulation calculator. For example, you can observe the cervical mucus, measure your body temperature, or use an ovulation test that reacts to changes in sex hormone concentrations in the urine. Obstetricians and gynecologists can also use ultrasound to make ovulation directly visible.

Sex every two to three days

Couples who want to have children can increase their chances of conceiving even without a fertility calendar: Those who have sex every second to third day generally "catch" the fertile days without any calculation experiments.
