“…However correlation coefficients calculated within groups in the present experiment failed to disclose a consistent significant relationship between cortisol levels (and presumably ACTH) and aggression. Furthermore, Bronson (cited in [8]) reported a failure of either physiological or pharmacological doses of ACTH to alter the frequency of aggression in intact, previously isolated C57 mice, and Sigg [25] found that intact adrenals were not necessary for the induction of aggression by isolation in mice. Indeed, he found heavier adrenal glands in the aggressive isolated animals.…”

“…Indeed, he found heavier adrenal glands in the aggressive isolated animals. Bronson and Desjardins [8] further note that experience in a chronic social situation may serve to increase variability in the adrenal-aggression relationship, and that plasma concentrations of corticosterone may not be significantly different in subordinant and dominant mice allowed to live together for 7 days [10]. Therefore, as noted by Leshner [ 19], the relationship between pituitary-adrenal hormones and aggression is by no means simple and universal.…”

“…Even where a relationship between androgens and dominance has been discovered it is often unclear whether a difference in testosterone caused the dominance pattern or resulted from it (Beach 1965). Luteinizing hormone and testosterone levels rise during a male 'challenge' (Wingfield et al 1990) or after exposure to a receptive female (Batty 1978;Bronson & Desjardins 1982) and can fall quickly after a defeat (Bronson & Desjardins 1971;Bronson et al 1973;Martinez et al 1989). Testosterone levels also fluctuate greatly even *Present address: US.…”

Abstract. Testosterone enhances aggression and can facilitate dominance in mammals, but most studies have been conducted on laboratory strains of mice and in simple environments. Unlike previous studies, laboratory and field tests were conducted using wild house mice, Mus musculus, to determine whether males with high, but physiological, testosterone levels (High T) would achieve dominance compared with males with low testosterone levels (Low T). All males were castrated and androgen was replaced with a single injection of testosterone enanthate, a long-acting androgen. At 8 days post-treatment the mean testosterone concentration in High T males was 5 . 1 ng/ml, whereas the level in Low T males was 1 . 3 ng/ml. Contests in the laboratory revealed that High T males achieved dominance over Low T males in the presence of females. In the field, equal numbers of High and Low T males, and a corresponding number of females, were released on three highway islands at densities equivalent to the highest density reported on similar sites. Periodic retrapping produced a capture history for males in each group and differences in survival were analysed using the program SURVIV. High T males had a higher probability of survival than Low T males on one island, but on the other two islands the higher capture rates of High T males were not statistically greater than those for Low T males. Of those that survived to the first trapping episode, the High T males had greater subsequent longevity than Low T males. On all three islands High T males were caught more frequently at feeding stations that were established to enhance food competition. There were no differences among the home range sizes of High T males, Low T males and females. However, on two of the islands the ranges of High T males overlapped more of the ranges of resident females than those of Low T males. The findings from this study, using testosterone-treated subjects, suggest that natural variation in basal testosterone also may affect competitive ability in wild house mice.

“…Indeed, the dominant and subordinate mice of this group showed similar aggressiveness. If they had many fighting experiences, they might have distinct dominant characteristics, as noted in the observation of Parmigiani and Brain (1983), or subordinate, because defeat leads to increase in pituitary-adrenocortical activity and decrease in androgen activity (Bronson & Desjardins 1971;Bronson & Eleftheriou 1965), and thus decreases subsequent fighting (Scott & Fredericson 1951).…”

Aggression and preputial gland of male mice affected by the presence of other males

--The level of aggressiveness and the weight of preputial gland and testis in male mice (Mus musculus) were influenced by housing condition, especially by the presence of cohabitant males. In this study, the relation between aggressiveness and the preputial gland and testis weight was studied for various housing conditions. The mouse individually housed in a cage that was linked to another cage containing another male separated by wire net was more aggressive than isolated or paired mice. The preputial gland weight also showed the same tendency, suggesting that the odor from other males promotes pituitary-gonadal activity in males, and that long-term cohabitance inhibits it.
