The premise of this comment is absurd, and that meta-analysis is hilarious. "Testosterone level isn't closely linked to aggression, at least compared to being a man and a criminal." This is a case of common sense, and thousands of years of experience in the effects of castration on humans and animals, being more valuable than modern "science".

I thought I remember hearing one of the side effects of taking roids (steroids) is that the abuser loses self control more frequently and has tantrums and aggressive behavior and the like. Is that true?

At least according to several studies (though unsure if they're included in the above meta-analysis), the government's drug abuse pages, countless anecdotes, and the existence of the term "roid rage".

Castration is a lot more then just reducing testosterone levels.

Yeah, I was wondering how much questionable pop-sci crap that was when I was writing it. Thanks, I'll have to read more into it.

So why post it? You rationalize and give credence to goofball theories for fun?
