The relationship between testosterone and aggression may operate indirectly, as it's been proposed Half Off that testosterone will not amplify tendencies to aggression, but fairly amplifies whatever tendencies will permit an individual to keep up social standing when challenged. For most animals, aggression may be the usually means of preserving social position. However, people have many means of obtaining status. This might reveal why some studies locate a backlink between testosterone and pro-social behaviour, if pro-social behaviour is rewarded with social standing. Consequently the link among testosterone and aggression and violence is due to these currently being rewarded with social position.[128] The connection may also be certainly one of a "permissive influence" whereby testosterone does elevate aggression concentrations, but only within the sense of enabling regular aggression concentrations to get preserved; chemically or physically castrating the individual will minimize aggression amounts (however not remove them) but the individual only wants a small-level of pre-castration testosterone to have aggression levels to return to ordinary, which they will keep on being at although more testosterone is extra.
