Male-to-Female Transsexuals Show Sex-Atypical Hypothalamus Activation When Smelling Odorous Steroids

Part II

Could C cause both A and B? This hypothesis is consistent with the facts. The fact that 1 in 5 DES-exposed 46xy infants are TS is inexplicable otherwise. We even have a chain of causation, based on other evidence involving hormones and mixed-gendered twins in both human and animal studies. There has to be a way, not yet well understood, in which observable pubertal development is "foreordained" by the hormonal environment in the womb. Transsexuality can be explained by more subtle effects in the same neural area before puberty - see Milton Diamond's paper on the subject, quoted at http://aebrain.blogspot.com/2008/06/bigender-... .

It is likely that genetic predisposition plays a role. The "1 in 5" TS following DES is similar to the "1 in 10" incidence of phocomelia caused by Thalidomide, the symptoms of which required genetic predisposition in the foetus.

Nope. The ADA specifically excludes transsexuals. Transvestites too, so bad they get excluded twice.

Sec. 12208. Transvestites

For the purposes of this chapter, the term "disabled" or "disability" shall not apply to an individual solely because that individual is a transvestite.
