Ethanol effects on female aggression vary with opponent size and time within session.
Female rats displayed different patterns of attack to large and small male intruders into their home cages, as a function of ethanol dose levels. In confrontations with small male intruders, female attack increased significantly at 0.3 g/kg ethanol, declining to saline levels with higher doses (0.6 and 1.2 g/kg). Attack toward large intruders was (nonsignificantly) higher at 0.3 g/kg ethanol, and declined to significantly lower than saline levels with the higher ethanol doses. The attack increases seen with low ethanol doses came in the initial 5-min block of the 30 min test session, and did not persist. These findings suggest that low ethanol doses may especially increase overt aggression in situations in which the tendency to attack is only moderately inhibited by factors such as opponent size or the potential danger of retaliatory attack.

The effects of ethanol on the offense and defensive behaviors of male and female rats during group formation.
In order to determine the effects of ethanol on social/agonistic interactions of rats in mixed-sex groups, saline or 0.3, 0.6, or 1.2 g/kg injections of ethanol were given to one male in 3 M, 3 F groups just prior to placement of the animals in a colony situation. Scores of offensive behaviors by the treated males generally declined as a function of dose level, but only with the 1.2 g/kg dose were behavior scores significantly different from the saline control. Ethanol effects on defensive and sexual behaviors were not significant. The proportions of attacks directed at females by males given higher ethanol doses increased sharply and significantly. Females were not attacked more by untreated males in the same groups where treated males showed selective attack on females. These findings suggest that increasing levels of ethanol administration may produce changes in male rats' choices of targets for attack, with females becoming relatively more likely to be targets.

The influence of females upon aggression in domesticated male rats (Rattus norvegicus).
The aggression of adult male Long-Evans rats (Rattus norvegicus), toward males of the same strain, was tested before and after a 1-week period of cohabitation with a pair of intact females, ovariectomized females, or intact males, comparable to the females in size. Only cohabitation with intact females increased the aggression of resident males against unfamiliary male intruders. Female enhancement of aggression does not appear to be caused by sexual frustration of males, or a function of dominance-subordinance relations, per se. Increased aggression may be mediated by elevated testosterone production associated with mating.
