Does anyone know (or have heard of) twins, either fraternal or identical who are crossdressers?
Don't ask why this popped into my head... I'd bet money that the identical twins would be more prone to both being crossdressers than the fraternal twins, if the causes are primarily genotype related (as in FtoM TS, the CYP17 gene).
But if CD/TG/TS is a function of a change in development of the BSTc (Zhou, et alia, 1995) or INAH3 areas of the amygdala / hypothalamus from conception, there could be a chance that the identical twins might differ in CD/TG expression.
What say you?
