Could you explain precisely what you mean by a "female brain structure", and how you would determine that a male has such a brain structure?

From broad brain traits like sexual orientation down to smaller ones like spatial perception or emotional intelligence, a young brain has certain development windows in which a trait or ability can get more or less developed. You could even add in personality traits like competitevness or deference once you associate it with a gender role.

With "female brain structure" i mean traits that are commonly overrepresented in what you might see as a regular woman. I know its inaccurate but so is the opposite, by saying there are only 2 genders and men are all men. Gender is a spectrum in many dimensions and my example of male physique and female brain structure is just a simple counter example against this.

The latest research doesn't really show that though, more that there is so much overlap between what were previously considered typically male and female differences in structure, such that this whole "female brain in a male body" hypothesis doesn't have the evidence to support it.
