Few clinical definitions, established by obscure researchers in obscure institutions, referring to an obscure subject, can have caused more brouhaha than Ray Blanchard’s definition of autogynephilia as ‘a man’s paraphilic propensity to be sexually aroused at the thought or image of himself as a woman.’
Brain Sex? What is that? Some sort of cyber-intercourse?
No. ‘Brain sex’ is how many transgender activists explain how their condition came about. They specifically say that, ‘Transgender occurs when an individual of one sex has certain sex-related structures in the brain that are typical of the opposite sex.’
In other words, according to this notion, ‘brain sex’ is a physical condition and not a psychological one. Putting that more technically, what is being claimed is that what they call ‘transgender’ — not a scientific term — is caused by a form of intersexuality that is localised in the brain. This is ‘brain sex’. However, physical heteromorphism of this type should be observable. So is it?
