Testosterone is one of the most important hormones for men. Because it controls the development of male sexual characteristics and the reproductive functions of the body, it also plays a decisive role in your overall health and physical and mental well-being.
Excess of this hormone can cause many problems in the body and personality of the individual such as mood swings and aggression, as testosterone also acts on the nervous system and, when high, changes the mood and makes the man more aggressive. With increasing aggression, a person may experience problems with delinquency, heavy drug use, and aggressive responses to bullying, similar to what is happening with David. Levels of this hormone are usually higher in adolescence, but as the individual ages, the level of testosterone in their body tends to decrease.
