when they go wrong together, they affect both brain and body

Sorry, I wasn't clear. I was conjecturing that there may be single changes in brain development that affect multiple sex-related things in the brain; if so, it would be unsurprising for those things to go wrong together even without changes elsewhere in the body.

Should I take it that you don't intend to answer the questions I asked at the end of the great-great-grandparent of this comment? Of course you're under no sort of obligation to answer any questions at all, but I do find it quite interesting how consistently unwilling you are to clarify your statements and opinions in this discussion.
