Ovulation calculator
A ovulation computer is a means for calculating the female cycle , it is therefore also called cycle computer , respectively.
Basics
Other names are ovulation calculator , ovulation calculator or ovulation calculator . With this calculator women can calculate and predict their ovulation , their fertile or infertile days or the onset of their next menstrual bleeding . Women who want to have children can thus plan the most favorable time for sexual intercourse. With this knowledge, pregnancy can also be avoided in a targeted manner . The method Pearl Index of such calendar-based methods is very high with a value of around 9. Such computers are therefore not recommended for prevention. The ovulation calculator is based on the Knaus-Ogino contraceptive method (which is now considered obsolete) . Since ovulation can take place at a time other than the one calculated, the calculation if you want to have children is just as questionable as the efficiency of contraception.
The ovulation calculation requires the start of the last cycle and the average duration of the cycle. In order to increase the informative value of this natural method of contraception, it makes sense to observe the cycle closely for a few months and to record the beginning and end of the periods in a menstrual calendar. In this way, the average duration of the individual cycle can be calculated.
Other forms
These calculators are available in a wide variety of shapes and materials. They can often be found on the Internet in virtual form as web-based computers, but apps for smartphones are also offered in app stores . For women in developing countries , developed Maria Hengstberger a birth control chain . Because this “calculator” is easy to use, it offers illiterate women the opportunity to estimate the time of their fertile days and thus to control their number of births to a certain extent. Where the birth control chain has been applied, the birth rate has been reduced by more than 50%.
