I wonder if that's a result of autism being under-diagnosed in women (and that under-diagnosis carrying over to trans women).
To elaborate: I was wondering if trans men (AFAB) acquire the male-gendered autistic traits and trans women (AMAB) acquire the female-gendered traits (and underdiagnoses from diagnostic criteria being focused on male norms).
Why I'm curious: I was diagnosed with Asperger's as an adult (no access to MH care as a child because raised in a cult), transitioned, and after 3 years of HRT got a new psych who laughed at the idea that I could have AS and removed it from my chart. His reasoning was that my interpersonal skills were not impaired in a way that is typical of autistic people. This is a common reason why women with autism are under-diagnosed.
I had terrible interpersonal skills pre-transition. HRT gave me access to a wider range of emotions, which might have something to do with it. E.g. I can actually understand the emotional currents in movies, which is nice. But, now I'm curious if autistic symptoms are another one of those things that change with hormones.
Interestingly enough, the correlation is observed to a greater extent with trans men (though not in all studies).
