title: [Problems in the evaluation of contraceptives (author's transl)].
abstract: For the evaluation of the effectiveness of contraceptives the Life Table method is at present the best method. It is a disadvantage that the original method of Tietze & Potter was restricted to the evaluation of intra-uterine contraception devices. A Belgian team is now in the process of developing a modified life table method for the evaluation of the effectiveness and the side effects of oral contraceptives. The reference to the Pearl-index for the effectiveness of contraceptives is unclear and in the way in which it is at present used scientifically untenable.
