Question

Quizplus · Accepted Answer

Research has shown that there is a relationship between testosterone levels and aggression, but it is more complex than a simple cause-and-effect relationship. In humans, gender differences in aggression appear early in life, but the effects of testosterone on aggression wane as levels decline during adulthood. This suggests that other factors, such as social and environmental factors, also play a role in determining levels of aggression in individuals. Additionally, research on administering testosterone to animals has found that it can increase aggression rather than reduce it.
