Cycle monitoring – determining the fertile days

How does cycle monitoring work?

The follicle growth and the building of the endometrium is monitored via ultrasound.

In this way, the fertile days can be very accurately determined and we can give you a recommendation for when to have intercourse. This can maximise your chances of getting pregnant.

The fertile days in the female cycle are limited to only a few days around the ovulation. Under optimum conditions, sperms can survive up to 2 days, whereas the egg cell can only be fertilised for approx. 24 hours after the ovulation and then – if no fertilisation takes place – dies.

The approach of cycle monitoring aims at determining and utilising this time frame


Is intercourse at the optimum time an option for us, too?

The most important preconditions for successful intercourse at the optimum time are that the fallopian tubes are open and your menstruation cycle proceeds in a normal fashion. The spermiogram of the male partner must not show any anomalies either.

The woman’s age also plays a key role where intercourse at the optimum time is concerned, since even if intercourse takes place during the most fertile days, fertilisation is not guaranteed. For women between the age of 20 and 25, the chance of getting pregnant is approx. 30 percent in each cycle.

From an age of more than 35, this chance is only half as great and, by the start of 40, it is reduced to approx. 10 percent.  

In the context of a comprehensive reproductive medical examination at the Kinderwunsch Institut, we can determine whether intercourse at the optimum time is an option for you and in which way we can support you on your way to the baby you’ve been waiting for so long.
