3440:"feminine and demasculinized" and in FtM it was possible to find traits which are "masculine and defeminized" (Kreukels & Guillamon, 2016)....Due to conflicting results, it was, however, not possible to identify specific brain features which consistently differ between cisgender and transgender nor between heterosexual and homosexual groups. Very small brain changes, to date undetectable using the current neuroimaging tools, may affect behavior. The small number of studies, the small sample size of each study, the heterogeneity of investigations, the lack of negative results reported by some studies, and the fact that some studies did not report the sexual orientation of the individuals that composed their sample did not allow drawing general conclusions. Moreover, as the samples of the publications involved are not representative of the population analyzed, caution should be taken in the interpretation of the results of this review. 1850:, which is generally thicker in cisgender women's brains than in cisgender men's brains, may also be thicker in trans women's brains, but is present in a different location to cisgender women's brains. It also stated that for both trans women and trans men, "cross-sex hormone treatment affects the gross morphology as well as the white matter microstructure of the brain. Changes are to be expected when hormones reach the brain in pharmacological doses. Consequently, one cannot take hormone-treated transsexual brain patterns as evidence of the transsexual brain phenotype because the treatment alters brain morphology and obscures the pre-treatment brain pattern." 1829:(2006) studied gross brain volume in 8 trans men and in 6 trans women undergoing hormone therapy. They found that hormones altered the sizes of the hypothalamus in a gender-consistent manner: treatment with masculinizing hormones shifted the hypothalamus towards the male direction in the same way as in male controls, and treatment with feminizing hormones shifted the hypothalamus towards the female direction in the same way as female controls. They concluded: "The findings suggest that, throughout life, gonadal hormones remain essential for maintaining aspects of sex-specific differences in the human brain." 1902:, which is generally thicker in cisgender women's brains than in cisgender men's brains, may also be thicker in trans women's brains, but is present in a different location to cisgender women's brains. For trans men, research indicates that those with early-onset gender dysphoria and who are gynephilic have brains that generally correspond to their assigned sex, but that they have their own phenotype with respect to cortical thickness, subcortical structures, and white matter microstructure, especially in the right hemisphere. 1718:(and which is affected by prenatal androgens), cadavers of six trans women had female-normal BSTc size, similar to the study's cadavers of cisgender women. While the trans women had undergone hormone therapy, and all but one had undergone sex reassignment surgery, this was accounted for by including cadavers of cisgender men and cisgender women as controls who, for a variety of medical reasons, had experienced hormone reversal. The controls still had sizes typical for their sex. No relationship to sexual orientation was found. 2032:, and quality of adjustment. However, the theory has been criticized in papers from Veale, Nuttbrock, Moser, and others who argue that it is poorly representative of trans women and non-instructive, and that the experiments behind it are poorly controlled and/or contradicted by other data. A 2009 study by Charles Moser of 29 cisgender women in the healthcare field based on Blanchard's methods for identifying autogynephilia found that 93% of respondents qualified as autogynephiles based on their own responses. 1864:
women, and cisgender women all had decreased connectivity compared with cisgender men in superior parietal regions, as part of the salience (SN) and the executive control (ECN) networks. Trans men also had weaker connectivity compared with cisgender men between intra-SN regions and weaker inter-network connectivity between regions of the SN, the default mode network (DMN), the ECN and the sensorimotor network. Trans women had lower small-worldness, modularity and clustering coefficient than cisgender men.

Late-onset gender dysphoria does not include visible signs in early childhood, but some report having had wishes to be the opposite sex in childhood that they did not report to others. Trans women who experience late-onset gender dysphoria are more likely be attracted to women and may identify as lesbians or bisexual.

Most notably, transmasculine subjects not only had the variant genotype more frequently, but had an allele distribution equivalent to cisgender male controls, unlike the cisgender female controls. The paper concluded that the loss of a female-specific CYP17 T -34C allele distribution pattern is associated with transmasculinity. 1838:
