WTF
I'm not really sure what this research, if you can call it that shows.
Men who have been castrated early enough in life so they have major hormonal changes so they are different from normal men.
I'm not really sure the survey sample or control group have any bearing on the wider population.
"This is the strongest evidence yet that testosterone the key difference between the eunuchs and their peers in this study **and a proxy for the difference between women and men** plays a role."
A proxy for the difference between men and women - what a complete load of bollocks. It's obvious to anyone with a brain that this is complete rubbish, and the life and body chemistry of Eunach's is completely different from women. The circumstances of women and events in their lives through growth, sexual maturity, childbirth, menopause etc has not even been touched on, and it you say a man with no balls is broadly similar, you need fired for repeating this utter rubbish.
