This is due to some kind of defect in the brain that we still don't know how to identify, much less fix.
Is it tho? If it can't be identified it could be 100% nurture. I know the progressive crowd will always point to that one study that does a PCA on brain structure and finds MtF are closer to F than M are to F on average (and contrariwise), but if you actually look at it the MtF are in an overlapping cloud with M and far from the F and FtM (who contrariwise are in a cloud overlapping with F but on the M facing side on average) which is kind of the opposite to what the woke crowd argue. They use a linguistic trick to say "MtF are closer to F than M" by which they mean "MtF are closer to F than MtF is to M" but it's actually saying "MtF are closer to F than M is to F" and even this the original author stated could be related to brain plasticity.
"to say "MtF are closer to F than M" by which they mean "MtF are closer to F than MtF is to M" but it's actually saying "MtF are closer to F than M is to F"
Moreover, the "trans lesbians" ( autogynephiles, heterosexual males with a fetish of seeing themselves in "woman version" ) do not show the same partial feminisation of a few brain structures.
And homosexual males have the same partial feminisation of a few brain structures regardless of "gender identity".
TL;DR : Most "trans science" on brain structure is basically detecting a physiological inclination for homosexuality, and running with that to draw flimsy conclusions.
While ignoring that "trans lesbians" brainscans falsify their hypothesis.

Finally someone with acurate knowledge and not a headful of steam and bullshit based on their feefees.
