Awareness and educational efforts are working to help prevent anabolic steroid abuse in schools and communities. The Adolescents Training and Learning to Avoid Steroids (ATLAS) and the Athletes Targeting Healthy Exercise and Nutrition Alternatives (ATHENA) programs, funded by the NIDA, and supported by the Oregon Health & Science University programs is teaching athletes that they do not need steroids to build powerful muscles and improve athletic performance. These programs provide weight-training and nutrition alternatives, increase healthy behaviors, less likelihood to try steroids, and less likelihood to engage in other dangerous behaviors such as drinking and driving, use of marijuana and alcohol , and and improved body image. Bother Congress and the Substance Abuse and Mental Health Services Administration endorsed these model prevention programs. 4
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.
