**4.2. OXT and male human aggression**

Compared to the interest in OXT and human prosocial behavior, there are few studies of the role of OXT on male aggression. The established effects on affiliation and prosocial behavior in animals and humans support the hypothesis that OXT has inhibitory effects on aggression. Conversely, some have postulated that OXT's anxiolytic effects could result in increased aggression, but there are no behavioral data in support of this theory. One potential clinical role of OXT is in the treatment of PTSD associated aggression.
