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 any birth control method.
Safety of the method
If, out of 100 women using a contraceptive over the period
of one year, 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. In other words Baby-Comp
and Lady-Comp offer a 99.3 percent safety against unwanted
pregnancy. (Based on independent clinical studies documented
by the manufacturer)
This safety of the method is to be differentiated
from the safety in use.
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
happen 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.
