The guide for safety of all contraceptive methods. The Pearl-Index is the value used in medical science to indicate the safety rate of birth control methods.
If 100 women use a contraceptive method over the period of one year and one woman becomes pregnant, the Pearl-Index is 1.0.
According to the latest clinical studies Baby-Comp and Lady-Comp have a Pearl-Index of 0.7 or 99.3% safety against unwanted pregnancy on green light days. (Based on independent clinical studies documented by the manufacturer)
The safety in use shows the reliability of the method in daily life. It accounts for all unwanted pregnancies which occurred due to the negligence of the instructions.
Unwanted pregnancies with Baby-Comp or Lady-Comp occur if intercourse has taken place during the "fertile" (= red) and "uncertain" (= yellow) days or if additional contraception (e.g. condom, diaphragm) was not used correctly.
The safety of the method in use for Baby-Comp and Lady-Comp varies between countries. For Switzerland and Germany it is 3.8.
