Cambridge scientists have shown that girls and boys show differences in what they pay attention to, even at birth. Since these differences are present so early, it is possible they emerge due to prenatal factors.
I would think they would have to do a huge study upon birth just to get a decent number of possible trans people to determine anything and then have to wait like 20 years to continue it. Getting funding for such a study might be a problem.
