Transsexual Women On Testosterone Think More Like Men

Here’s a sex change fun fact. Researchers studying women transitioning from female to male found that women taking testosterone for gender reassignment started thinking like men when they started taking testosterone.

The study was presented at the annual meeting of The European College of Neuropsychopharmacology (ECNP) in Amsterdam, which brings together 4000-7000 neuroscientists, physicians, psychiatrists, and pharmacists.

Brain imaging using MRI (magnetic resonance imaging) was performed before and after taking high dose testosterone for four weeks. Testosterone “shrunk” the parts of the brain associated with verbal skills, which suggest that females like to talk more than males do!

18 female-to-male subjects (27-years-old, plus or minus 6.4 years) who underwent the treatment were found to have decreased grey matter in two specific area of the brain, the Broca’s and Wernicke’s area, which are responsible for language processing.

According to Dr. Andreas Hahn of Vienna “It has been known for some time that higher testosterone is linked to smaller vocabulary in children and that verbal fluency decreases in male-female transsexuals.” Researcher Prof. Rupert Lanzenberger of Vienna added “This would have been impossible to understand without looking at the transsexual population. The genuine difference between the brains of women and men is substantially attributable to the effects of circulating sex hormones.”

So there you have it; blame the “war” between the sexes on sex hormones.
