[The forensic value of the length and weight of newborns, the placental weight and the correlation between placental and newborn weight in the evaluation of paternity (author's transl)].

The length of the infant, the weight of the infant, the weight of the placenta, and the correlation between the weight of the placenta and the weight of the infant are coarse parameters for the estimation of the maturity of an infant. We plotted these parameters of 20,000 deliveries in relationship to the stated length of gestation from 23--46 weeks. Our results correspond to those quoted in the literature. The values of the parameters show a marked variation which is accentuated by the small number of cases with very short or very prolonged gestation. These parameters are only of limited value in the determination of the paternity. The mean values including the first standard deviations are of some importance.
