睾酮与人类攻击行为

estosterone is an androgen synthesized and secreted by the Leydig cells of the testes in men, the thecal cells of the ovaries and placenta of women. It can mediate various physiological, morphological, and behavioral processes, and is vital to human survival and reproduction. A large number of studies have shown that there is a bidirectional relationship between testosterone and social behavior. Testosterone can regulate various social behaviors, which in turn feedback and affect the testosterone level. Early research showed that individuals with high testosterone level are more aggressive. According to the challenge hypothesis and the biosocial status model, recent studies have revealed that testosterone is highly responsive to competitive interactions. In addition, by reviewing these studies, we suggest that changes in testosterone can affect aggressive behavior by enhancing the reactivity of the amygdala or reducing PFC-amygdala functional coupling. Future research could consider the potential role of other hormones (such as cortisol) and personality traits in regulating the relationship between testosterone and human aggressive behavior, as well as related biological mechanisms.
