[Calculation of the Pearl Index of Lady-Comp, Baby-Comp and Pearly cycle computers used as a contraceptive method].

Introduction: Lady-Comp, Baby-Comp and Pearly cycle computers are medical devices that use sophisticated statistical gathering methods, as well as a comprehensive database, to precisely determine fertile and infertile phases of a menstrual cycle on the basis of everyday basal body temperature measurements. They have been produced and distributed worldwide by Valley Electronics GmbH (Eschenlohe, Bavaria, Germany) for over 25 years.

Objectives: The aim of the study was to calculate the Pearl Index of cycle computers in order to determine their contraceptive effectiveness.
