Abstract

To determine if the lateral ventricular atrial diameter differs between male and female fetuses at 20-24 weeks' gestation. Prospective study. The transverse diameter of the ventricular atrium was measured from inner wall to inner wall for a total of 202 pregnant women with 105 male fetuses and 97 female fetuses. The mean diameter of the ventricular atrium for the 202 fetuses was 4.96 +/- 0.96 mm (range, 2.1-8.4 mm). The 105 males had a mean diameter of 4.95 +/- 0.98 mm and the 97 females a mean diameter of 4.97 +/- 0.94 mm. There was no statistical difference between the sexes. In our population, there was no difference between ventricular atrial diameter in male and female fetuses at 20-24 weeks' gestation.
