The easiest way is by doing a CAT scan of the BTSc section of the hypothalamus - it's 62% larger in hetero males than in hetero females. In cases of true transsexuality, they have (for instance) male parts, but a small (female) BTSc, or have female parts, but an enlarged (male) BTSc. That was the point of my earlier post - it's a medically verifiable condition.
BUT, you're giving average stats. There is huge variation between individuals within each gender, and a huge overlap in the individual size ranges for the two genders. I'm sure my brain has a lot of male-leaning anatomical characteristics, even though I'm quite contentedly female. I have unusually good spatial skills for a female (and probably well above average by male standards), a more assertive and goal-oriented personality than most females, and, um, I rarely stop and ask for directions even when I am demonstrably lost (much prefer trying to decipher a map). And I'm sure there are plenty of men who are quite content with their gender, who have brains that look anatomically more female than mine.
You write as if "homo" is a legitimate condition, rather than the socially enforced perversion it is. Transgendersim?; another totalitarian attempt to force people to tolerate, accept, and embrace the most bizarre, illogical, and immoral concepts. (Just like North Korea.)The child in question is a girl; no amount of fanasy, social conditioning, or barbaric mutilation can change this fact. From your posts, I suspect you have your own agenda. Hands off this child!

CAT scans don't work for soft tissue analysis, not enough contrast. The other possibilities, MRI and Nuclear Medicine scans probably do not work because they may not be able to resolve a structure as small as the BTSC region.
The only way that such studies have been done, is post mortem with dissection of the brain
