It has been claimed that the human corpus callosum shows sex differences, and in particular that the splenium (the posterior portion) is larger in women than in men. Data collected before 1910 from cadavers indicate that, on average, males have larger brains than females and that the average size of their corpus callosum is larger. A meta-analysis of 49 studies published since 1980 reveals no significant sex difference in the size or shape of the splenium of the corpus callosum, whether or not… Expand

Sexual dimorphism in the human corpus callosum: an MRI study using the OASIS brain database.
TLDR
Evidence is provided that the midsagittal corpus callosum cross-sectional area in females is larger in females after correcting for the confounding effect of brain size. Expand
Sexual dimorphism of splenial thickness of corpus callosum
TLDR
MRI scans were studied for splenial thickness of corpus callosum in mid-sagittal plane & comparison was done in males & females by using two way ANOVA procedure and no significant sexual dimorphism in splenials thickness was found in the present study. Expand
Corpus Callosum Morphology in Capuchin Monkeys Is Influenced by Sex and Handedness
TLDR
Measurements of corpus callosum cross-sectional area from midsagittal MR images collected in vivo from 14 adult capuchin monkeys suggest that sex and handedness influences on corpusCallosum morphology are not restricted to Homo sapiens. Expand
Why size matters: Differences in brain volume account for apparent sex differences in callosal anatomy The sexual dimorphism of the corpus callosum
TLDR
The larger the discrepancy in brain size between men and women, the more pronounced the sex difference in callosal thickness, with hardly any callosal differences remaining between brain-size matched men andWomen. Expand
Relative Size versus Controlling for Size
The corpus callosum is the main tract of fibers providing communication between the left and right cerebral hemispheres. The question of a sex difference between human males and females in the size… Expand
Sex-related difference in human white matter volumes studied: Inspection of the corpus callosum and other white matter by VBM
It has been contended that any observed difference of the corpus callosum (CC) size between men and women is not sex-related but brain-size-related. A recent report, however, showed that the… Expand
Gender differences in the corpus callosum of neonates
TLDR
The gender difference of corpus callosum is a long standing controversy and midsagittal ultrasonographs were obtained through the anterior fontanelle of healthy Korean neonates and showed no gender differences, however, the male corpuscallosum had significantly more height than that of the female whereas there was no difference in width of the corpus callosi.

Measurement of the Corpus Callosum Using Magnetic Resonance Imaging: Analyses of Methods and Techniques
TLDR
Analyzing methodological differences in several studies using Magnetic Resonance Imaging to investigate the sexual dimorphism in the size of the corpus callosum found the hypothesis that methodoiogical differences could explain these differences is supported by statistical results. Expand
Size Matters: Cerebral Volume Influences Sex Differences in Neuroanatomy
TLDR
It is concluded that individual differences in brain volume, in both men and women, account for apparent sex differences in relative size. Expand
A critical re-examination of sexual dimorphism in the corpus callosum microstructure
TLDR
A stronger inter-hemispheric connectivity between the frontal lobes in males than females is indicated, which might be related to sex differences in hemispheric asymmetry and brain size. Expand

Variations in human corpus callosum do not predict gender: a study using magnetic resonance imaging.
TLDR
Measurements of the human corpus callosum using magnetic resonance images of 37 living subjects failed to confirm reported sex differences in the splenium and found large variations in callosal size and shape among individuals regardless of age or gender. Expand
Sex differences in the corpus callosum of the living human being
TLDR
While there was no conclusive evidence of sexual dimorphism in the area of the corpus callosum or its subdivisions, there was significant sex differences in shape, which could, in part, underlie gender-related differences in behavior and neuropsychological function. Expand
Sexual dimorphism of the human corpus callosum from three independent samples: relative size of the corpus callosum.
TLDR
Three independent autopsy samples of brains without apparent neuropathology were studied to ascertain whether there was sexual dimorphism in the human corpus callosum (CC), and the CC is the only structure to show a larger set of relative measures in females. Expand
Sexual dimorphism in the human corpus callosum: an extension and replication study.
TLDR
Using a new sample of 16 human brains, it was found that the splenial portion of the corpus callosum was larger and more bulbous in females than in males, providing a partial anatomical basis for purported gender differences in cognitive task behaviour. Expand
The influence of sex, age, and handedness on corpus callosum morphology: A meta-analysis
Initial observations linking variation in the human corpus callosum (CC) to handedness and sex have inspired a number of investigations of individual differences in CC size and morphology. In this… Expand
The controversy about a sexual dimorphism of the human corpus callosum.
TLDR
The posterior part of the female corpus callosum was described to be larger and more bulbous than its male counterpart and the "rotatory diameter measurement" was performed and no differences between the sexes were seen either for the splenium corporis callosi or for the other parts of the corpus callosi.

Anatomic variation of the corpus callosum in persons with gender dysphoria
TLDR
Even though there was a wide range of differences in shape and size in the splenium, the study found no significant differences between the sexes or between transsexual patients of either sex and the controls. Expand
Sexual dimorphism of the human corpus callosum studied by magnetic resonance imaging: Fact, fallacy and statistical confidence
TLDR
The data in this large series support a limited but definite sexual dimorphism of the CC in right-handed individuals. Expand
Morphometry of the adult human corpus callosum: lack of sexual dimorphism.
TLDR
Researchers have studied 33 adult human brains, 17 male and 16 female, using a -variety of morphometric approaches to see whether they could detect a major anatomical difference between the brains of men and women. Expand
Effects of handedness and sex on the morphology of the corpus callosum: A study with brain magnetic resonance imaging
TLDR
It is suggested that at least two different sex-related--probably hormonal--factors may be acting during the callosal development, one explaining the larger anterior half in NCRH males and the other the larger posterior midbody in CRH females. Expand
