We investigated differences in corpus callosum shape at the midsagittal plane using MRI for different subjects: normal males, normal females, and subjects with gender identity disorder (GID). We first represented callosal shapes with Fourier descriptors of callosal contours. Using linear support vector machines with soft-margin, we next determined a hyperplane that separates normal males and females most optimally in the vector space spanned by Fourier descriptors. We then proposed a measure… 
Corpus Callosum Anatomy in Right-Handed Homosexual and Heterosexual Men
The findings indicate that neuroanatomical structure and cognition are associated with sexual orientation in men and support the hypothesis of a neurobiological basis in the origin of sexual orientation.
Cortical thickness in untreated transsexuals.
FtMs showed evidence of subcortical gray matter masculinization, while MtFs showedevidence of CTh feminization, in both types of transsexuals, the differences with respect to their biological sex are located in the right hemisphere.
White matter microstructure in female to male transsexuals before cross-sex hormonal treatment. A diffusion tensor imaging study.
The results show that the white matter microstructure pattern in untreated FtM transsexuals is closer to the pattern of subjects who share their gender identity than those who share the biological sex (females).
Regional Grey Matter Structure Differences between Transsexuals and Healthy Controls—A Voxel Based Morphometry Study
Structural MRI data with voxel based morphometry obtained from both FTM and MTF transsexuals are analyzed and support the notion that structural brain differences exist between transsexual and healthy control subjects and that majority of these structural differences are dependent on the biological gender.
Morphological Differences in Adolescent Female to Male Transsexuals before Cross-Hormone Treatment
Early-onset gender identity disorder (EO-GID) describes a strong and persistent development of cross-gender identification. Using structural magnetic resonance imaging (sMRI) and blood samples, we
The microstructure of white matter in male to female transsexuals before cross-sex hormonal treatment. A DTI study.
The results show that the white matter microstructure pattern in untreated MtF transsexuals falls halfway between the pattern of male and female controls, which suggests that some fasciculi do not complete the masculinization process in Mtf transsexuals during brain development.
A Review of the Status of Brain Structure Research in Transsexualism
It is hypothesize that cortical differences between homosexual MtFs and FtMs and male and female controls are due to differently timed cortical thinning in different regions for each group.
Effects of androgenization on the white matter microstructure of female-to-male transsexuals. A diffusion tensor imaging study
Observations suggest that testosterone treatment changes white matter microstructure in FtMs, and the increments in the FA values in the SLF and CST are predicted by the free testosterone index before hormonal treatment.
The transsexual brain – A review of findings on the neural basis of transsexualism
This review intends to give an extensive overview of structural and functional neurobiological correlates of transsexualism and their course under cross-sex hormonal treatment.

Present knowledge indicates the existence of many structures in the brain that are associated with sexuality and show sexual dimorphism. Interestingly, brain centers showing the relationship of


Sex but no hand difference in the isthmus of the corpus callosum
An effect of sex emerged, with women having a larger proportional isthmus segment of the corpus callosum, which may reflect a sex-specific difference in the inter-hemispheric connectivity and functional organization of the temporoparietal association cortex.
Anatomic variation of the corpus callosum in persons with gender dysphoria
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.
Sex differences in the corpus callosum of the living human being
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.
Sex Differences in the Human Corpus Callosum: Myth or Reality?
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 an appropriate adjustment is made for brain size using analysis of covariance or linear regression.
Anatomical-behavioral relationships: Corpus callosum morphometry and hemispheric specialization
The correlational findings are consistent with the view that the corpus callosum participates in such higher order "control" functions as the support of bilateral representation of language, functional interhemispheric inhibition, and the maintenance of hemispheric differences in arousal.
Sexual dimorphism in the human corpus callosum.
Preliminary observations suggest a sex difference in the shape and surface area of the human corpus callosum, and this finding could be related to possible gender differences in the degree of lateralization for visuospatial functions.
Gender Identity Disorders
The gender identity disorders (GID) are defined as disorders in which an individual exhibits marked and persistent identification with the opposite sex and persistent discomfort (dysphoria) with his
