Of course, everyone is buzzing on yet another bit of biological evidence related to the cause of classic transsexuality. Here are some of the headlines, all emphasis mine:
Official Journal of the Society of Biological Psychiatry:
There is a likely genetic component to transsexualism, and genes involved in sex steroidogenesis are good candidates. We explored the specific hypothesis that male-to-female transsexualism is associated with gene variants responsible for undermasculinization and/or feminization…A significant association was identified between transsexualism and the AR allele, with transsexuals having longer AR repeat lengths than non-transsexual male controls (p=0.04).
