Natural Family Planning is a method of planning which makes no use of hormonal, surgical or mechanical aids. There are no health risks. This method is used to accomplish child planning at the right time or to implement contraception reliably and consistently.
Natural Family Planning is a modern and reliable form of conception control. When the rules are consistently observed, pregnancy occurs only at the desired time.

The basis for Natural Family Planning is careful observation of the body signals which accompany the cycle events. The most basic analysed body signals include the waking temperature, which is of central importance to Natural Family Planning. This procedure, referred to as the temperature method, has made significant strides over the course of ten years. The technological change - from the glass thermometer to the cycle computer - has brought increased reliability and comfort. And with it increased acceptance too! The measured data and their representation in a fertility profile have increased in meaningfulness. When continuous measurements are made, it is possible to make reliable prognoses about the expected ovulation date and the non-fertile phase within one cycle.

cyclotest temperature computers record the waking temperature with a high degree of accuracy. The adaptive computer records the smallest temperature fluctuations, stores all the personal values and narrows down anew the fertile and non-fertile phases in each cycle. An intelligent chip stores and interprets the acquired data. As the number of measurements increases, so the accuracy with which the fertile days are determined increases. The more temperature values and information about the cycle duration are available, the more accurately the beginning and the end of the fertile phase can be narrowed down.
