Testosterone is thought to be the root of male aggression. Above average levels of testosterone have been observed in incarcerated violent criminals and in athletes engaged in semi-violent sports such as: football, lacrosse, and ice hockey.
The term “roid rage” has been applied to the explosive and often irrational behavior seen in men and women who use anabolic steroids (especially those that are highly androgenic) on a regular basis above the therapeutic dosage. Many marriages and friendships I have known have fallen on hard times as a result of the severe mood swings that many steroid users experience. The irritability experienced by males and females on anabolic /androgenic steroids are paralleled by a condition that millions of women each month endure, commonly referred to as “premenstrual tension syndrome”. Anabolic steroids, however, also have the opposite psychological effect in many abusers.
