New Brain Study Implications For Transvestitism

Yet more evidence that sexual orientation is biologically determined and has little to do with how people are raised comes from MRI and PET studies conducted at the Stockholm Brain Institute (abstract available) . The researchers found that brain shape and size was similar between gay men and straight women and between straight men and gay women. They also found that activity in an area of the brain called the amygdala had the same pattern.

Once more, the evidence suggests that gays are 'born that way' and that sexual orientation is not a 'lifestyle choice'.

What's this got to do with transvestites? Well, nothing really except that it provides further evidence that developments in the womb and early infancy can significantly alter brain structures which have outcomes in terms of sex-related behaviours. That something as significant as sexual orientation can be affected suggests to me that scientists should be looking more closely at how atypical brain development can lead to atypical gender presentation and gender identification preferences - i.e. transvestitism and transsexualism.

I have always argued that men like me, who cross-dress, do so because a part of our brains has been wired up the wrong way so that we feel the need to present ourselves as women. I believe that once we (the transgendered community), the psychological and psychiatric worlds, and the public in general accept this explanation, attitudes to transvestitism will begin to change. If the world (and especially the world of psychiatry) sees us not as 'perverts' or 'fetishists' but as perfectly ordinary people, coping with a small glitch in our brain's wiring, I can only think that we will be treated with more understanding and less contempt.

These studies on the neuroanatomy of gays don't help us directly but at least they establish the principle that such things are an accident of birth not the wilful embracing of a moral corruption.
