On the Science of Changing Sex

Transgender Teens Brains Crossed-Sexed

Teenage-brainBreaking News

A study out of the Netherlands (our favorite clinic where science is still happening) showed that adolescents with Gender Dysphoria, both MTF and FtM, have brain structures and activation like that of the opposite natal sex:


Please remember, this data only applies to “early transitioners” / “early onset”…. NOT adult “late onset” / “late transitioners”.  Given earlier studies which show that late transitioning transwomen do NOT have cross-sex brain structures we don’t expect to see the same results in adults.  I will follow up when I can find more information.

(Update 5/27/2018:  I still haven’t seen that paper, but I did learn that the adolescents in the study were taking Triptorelin to suppress puberty.  Some wags have already claimed that this effect was caused by the drug.  But, this is very unlikely as puberty suppression means that the activating effects of testosterone should be suppressed to allow us to see the earlier organizing effects or the lack there of more clearly, if only we had controls who were not gender dysphoric.  Someone else pointed out that sexual orientation is a known confound and was not controlled for.  This IS a concern if one believes that gender identity is potentially an atomic / neurological difference between gays & lesbians and transkids… which many of us, including myself, do not believe.)
