I don’t know enough about hormonal biology to guess a specific cause(some general factor of neoteny, perhaps??). It’s much easier to infer that it’s likely some third factor than to know exactly what third factor it is. I actually think most of the evidence in this very post supports the 3rd-factor position or is equivocal—testosterone acting as a nootropic is very weird if it makes you dumber, that men and women have equal IQs seems not to be true, the study cited to support a U-shaped relationship seems flimsy, that most of the ostensible damage occurs before adulthood seems in tension with your smarter friends transitioning after high school.
Like what exactly? That seems unlikely to me. I suppose we will have results from the ongoing gender transitions soon.

They seemed low-T during high school though!
Yeah could be a third factor though. Maybe you are right.
