If you ever want to understand the differences between men and women, read some books by women who have received testosterone to undergo sex changes to become men. They say things like "I became more interested in my career and earning money. I understood math and science better. I became more interested in technology and machines and less interested in people, etc."

It's quite fascinating stuff and makes you realise how different the sexes are.

I've never heard things like this. Do you have some sources? Something like that would be a real hit to our social system that fired Larry Summers from Harvard for saying there may be differences in aptitude in the sciences between men and women for biological reasons.

Here's a "This American Life" episode where they interview one person - it's act two - http://www.thisamericanlife.org/Radio_Episode.aspx?sched=123...

One book I read on the topic that I can remember is "The Testosterone Files" - http://www.amazon.com/Testosterone-Files-Hormonal-Social-Tra...

The author does an excellent job of describing his experience and the differences he noticed between being a women versus being a man.
