Safety in Use

The Pearl-Index

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.

Safety of the method

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)

Safety in use

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.

Women who experience cycles that are less than 19 days and more than 40 days may have reduced reliability when using natural methods for planning and prevention of pregnancy.  Lady-Comp, Lady-Comp Baby and Pearly are not recommended for preventing pregnancy in women who have very short (<19 days) or very long (>40 days), irregular cycles.
