Some here will try to claim transgender female brains are more similar to cisfemale brains, which is false. Its more or less in-between with diffetences but closer to cismen.
From 2022..
"The classifier performed at 90.2% accuracy (AUC = 0.97) when assessed in the training sample and at 88.3% accuracy (AUC = 0.97) when assessed in our 48 cisgender brains. These measures indicate a suitable classification performance and a reliable distinction between the sexes based on brain anatomy.
The estimated Brain Sex index was significantly different between the three groups (F(2,69) = 40.07,
p < 0.001), with a mean of 1.00 ± 0.41 in cisgender men and of 0.00 ± 0.41 in cisgender women.
The Brain Sex of transgender women was estimated as 0.75 ± 0.39, thus hovering between cisgender men and cisgender women, albeit closer to cisgender men (see also
Figure 1). The follow-up post hoc tests revealed that transgender women
were significantly more female than cisgender men (Cohen’s d = 0.64, t(46) = 2.20,
p = 0.016),
but significantly less female than cisgender women (Cohen’s d = 1.87, t(46) = 6.48,
p < 0.001)."
Transgender people report discomfort with their birth sex and a strong identification with the opposite sex. The current study was designed to shed further light on the question of whether the brains of transgender people resemble their birth sex or ...
