初步观察表明，人类的胼胝体在形状和表面积上存在性别差异。性的二型性在压部、胼胝体的尾部或后部非常明显。雌性鳞茎比雄性鳞茎更大，球茎更大。由于蠕动纤维、顶纤维和颞上纤维穿过压部，这一发现可能与视觉空间功能偏侧化程度的性别差异有关。
Preliminary observations suggest a sex difference in the shape and surface area of the human corpus callosum. The sexual dimorphism is striking in the splenium, the caudal or posterior portion of the corpus callosum. The female splenium is both more bulbous and larger than the male counterpart. Since peristriate, parietal, and superior temporal fibers course through the splenium, this finding could be related to possible gender differences in the degree of lateralization for visuospatial functions.
