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.  Although Lady-Comp, Lady-Comp Baby and Pearly are not contraception, their reliability in identifying the fertile and infertile days of the cycle was analyzed in consideration of the Pearly Index.

Pearly Index?

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 research the products have a Pearl-Index of 0.7 or 99.3% reliability in identifying the fertile and infertile days of the cycle. (As 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 of Family Planning.  The products may be less reliable for women who have very irregular cycles; short cycles (<19 days) or very long cycles (>40 days).
