abstract="We investigated the relationship between aggression, plasma testosterone level (T), and change in T in captive male red jungle fowl (Gallus gallus). T measured on day 1 of our experiment was positively correlated with T on day 8, suggesting that T remains constant in males when the social environment is stable. During aggressive encounters that escalated to include physical combat, males that attacked first (won) had increased T relative to their opponent. Males did not differ in T measured 1 week before the aggressive encounter. Our data suggest that an increase in T during aggression is associated with winning in escalated fights.<p /><p>Language: en</p>",
