That's something which appears to have been carried over from research on animals in the early part of the last century. With some effects being carried over to research in human males and females.Why? The point is that of course all women are different, but the muscle/mass ratio in men is far higher and testosterone much higher which means more aggression. This transwoman clearly should not be playing women's football, and it's absurd to argue otherwise.
"Conclusions
Research on testosterone and human aggression has its roots in animal studies, some of which showed a straightforward causal link in animals, for example in the classic ablation-replacement studies using laboratory mice. Studies on humans followed from the 1970s onwards, when an overall weak association was found between testosterone and aggression, but no effect of long-term injections of testosterone in men."[/I]
