Objective To determine if the lateral ventricular atrial diameter differs between male and female fetuses at 20–24 weeks' gestation. Design Prospective study. Methods 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. Results 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. Conclusions In our population, there was no difference between ventricular atrial diameter in male and female fetuses at 20–24 weeks' gestation.
