title: [The technique, accuracy and clinical significance of the ultrasonographic determination of the fetal sex].
abstract: Despite improved ultrasound methodology it is probably not possible to determine the fetal sex accurately prior to the twentieth week of gestation by ultrasound. The clinical significance of this non-invasive method of fetal sex determination is therefore still low. The technique and accuracy is discussed from studies of the literature and a personal investigation of one hundred and four cases.
