Abstract
Introduction: There is no uniformity in published works regarding the presence of sexual dimorphism in themorphology of the Corpus Callosum (CC), specifically splenium.Objective: The present study was conducted on formalin fixed preserved brains to get comprehensive dataregarding gender related differences of CC.Materials and Methods: 50 formalin fixed human brains without apparent neuropathology were cut in themidsagittal plane. The various morphometric features of CC were measured and recorded on these midsagittalsections.The diameters measured were: (i) length of CC (AB), (ii) Width of body of CC at mid point (WBM), (iii) Maximumwidth of genu (AE), (iv) Maximum width of splenium (BD).Results: Mean values of two parameters (AB and AE) were greater in male than in female. However, 2 parameters(WMB and BD) had greater value in female than male. Only two parameters (AB and BD) showed statisticallysignificant (p value < 0.05) gender differences.Conclusion:significant sexual dimorphism was observed in the longitudinal length of the CC, including morphologyof the splenium. However, these gender related differences are more likely due to individual differences regardlessof sex
