Sex difference in fetal atrial diameter may support sex-specific norms; Level 3 data leave open any threshold revision.
Does the diameter of the fetal lateral ventricular atrium differ between male and female fetuses?
Male fetuses have a slightly but significantly larger cerebral ventricular atrial size than female fetuses, which may affect the definition of the upper limit of normal.
Patel et al. (1995) studied this question.
