Fact:
Male brains are significantly larger than female brains, by about 10%. The brains are totally different sizes.
The proportions are also different. Women have proportionately more grey matter and a thinner cortex, which might explain

Meta-analysis of biological sex differences

There are significant differences in brain size, shape, and structure between the genders. A female brain is VERY DIFFERENT from a male brain.
-- The female brain is 10% smaller
-- Women have significantly less of everything. Gray matter, white matter, cerebral-spinal fluid.....everything. They have fewer neurons as well.
-- But if you control for intercranial volume, women have proportionately more Gray Matter, and a proportionately larger cortex.
-- Females have a thicker cortex, even in studies that control for ICV, body size, age....etc
-- Sex differences in the connectome, with females having more inter-hemispheric connectivity, while males having more intra-hemispheric connectivity
-- These sex differences are very similar to the differences observed in a huge host of animals studies, and should not be surprising to anyone.

So given that female brains are completely different from male brains, which brain do you expect transgenders posses? The brain of their biological sex? Or the brain of their chosen sex? Obviously, the brain of their biological sex.
>MRI studies show that ICV in adult and adolescent untreated homosexual MtFs is similar to male controls’. Moreover, GM, WM, and CSF volumes in homosexual MtFs do not differ from those of control males and are significantly greater than those of control females.

Transgenders have a male brain. They are not women, they will never be women. They are walking around with a male shaped brain.
