I was looking for a reference showing that childhood testosterone surges were an invention, and came across this article which although written almost 15 years ago would I think interest people here and ties into the He for She thing too. So I thought I'd share it and see if other people might like it too (not that I am saying every word is good mind!)
It's about boys performance at school, which is interesting, but the part I really found thought provoking was the section on masculinity and how damaging the 'boy code' is to both men and women.
