This is not my original post. I found it on another trans girl’s blog. It remains to be seen whether being trans could have a root in biology. All in all, this is a fascinating read, and will be geared more towards people who like studies and facts and not just mindless rambling of a cold(used to be hot) tea sipper! Enjoy!
Imaging studies and other research suggest that there is a biological basis for transgender identity
Some children insist, from the moment they can speak, that they are not the gender indicated by their biological sex. So where does this knowledge reside? And is it possible to discern a genetic or anatomical basis for transgender identity? Exploration of these questions is relatively new, but there is a bit of evidence for a genetic basis.
