Objective: To attempt to detect the presence of a gender difference in the size of the fetal lateral ventricular atrium. Methods: The width of the lateral ventricular atrium was measured sonographically on 543 consecutive fetuses scanned at 17–40 weeks, with a normal structural survey and documented gender assignment. Lateral ventricular measurements of male and female fetuses were compared. Results: The mean width (± S.D.) of the lateral ventricular atrium for the entire study population of 543 fetuses was 6.5 ± 1.4 mm. The measurement was 6.7 ± 1.3 in male and 6.3 ± 1.4 in female fetuses (P < 0.001). The atrial measurements were ≥ 8.5 mm in 10% of the male and 7% of the female fetuses (P > 0.05, NS). Conclusion: Male fetuses have slightly larger cerebral lateral ventricles than female fetuses.
