- Sobre el cerebro transexual, creo que ya lo habíamos discutido:
"Of course, behavior and experience shape brain anatomy, so it is impossible to say if these subtle differences are inborn."
El comportamiento y la experiencia moldean la anatomía cerebral,
por lo que es imposible decir si estas pequeñas diferencias son innatas.
- Sobre otro experimento similar:
They found that the adolescent boys and girls with gender dysphoria responded much like peers of their experienced gender.
The results were less clear with the prepubertal children.
Los resultados fueron menos claros en niños pre púberes

A pesar de que como grupo es fácil distinguir diferencias entre el cerebro masculino y femenino, los científicos no pueden determinar si un cerebro individual es femenino o masculino si no cuentan con información adicional del sujeto.
-Sobre el estudio de genes Australiano:
"This reduced action of the male sex hormone
may have an effect on gender development in the womb, the researchers
speculated.
"We think that these genetic differences
might reduce testosterone action and under masculinise the brain during foetal development," said researcher Lauren Hare from Prince Henry's Institute of Medical Research.
Terry Reed from the Gender Identity Research and Education Society said she was convinced of a biological basis to transsexualism.
"This study appears to reinforce earlier studies which have indicated that,
in some trans people, there may be a genetic trigger to the development of an atypical gender identity.
"However, it may be just one of several routes and, although it seems extremely likely that a biological element will always be present in the aetiology of transsexualism,
it's unlikely that developmental pathways will be the same in all individuals."

El estudio menciona que se "especula", "podría" y que es "muy improbable que se desarrolle de la misma forma en todos los individuos".
Habiendo dicho eso, me pareció interesante el tema de los genes y la testosterona. La hipótesis por el momento sería entonces que, debido a un gen, el accionar de la testosterona se vería reducido, provocando que el cerebro sea menos masculino aunque dicha influencia no sea manifiesta en el cuerpo?
