“…This result accords with previous findings that the presence of female mice facilitates male aggression (de Catanzaro 1981;Palmer et al 1984), and supports the theory that male mice compete to establish and hold territory and/or to establish social rank to mate with females (Palanza et al 1996).…”

The influence of female mice (Mus musculus) on intermale aggression and the female choice between dominant and subordinate males were tested. Normal male mice were paired with a castrated male or a female. Two pairs of the same kind were housed together after acclimation for 3 days in half (home cage) of the apparatus, which was composed of eight cages connected by tunnels. One of the two normal males became dominant. The dominant males became more aggressive in the presence of females than in the presence of castrated males. The two normal males dwelt in their own home cages. The two females dwelt together and preferred to dwell in the home cages of the dominant male. The two castrated males dwelt together and seemed to decide their dwelling cage more freely than the subordinate normal male.

“…Females facilitate intermale aggression (de Catanzaro 1981;Palmer et al 1984;Korpela and Sandnabba 1994). These findings were obtained from observations after the male mice had mated with females, and thus females or female odor were not always present during the observations.…”

“…The present findings, in agreement with other research [cf Barnett et al;1968;de Catanzaro, 1981;Dewsbury, 1981;Thor and Carr, 19791, attest to the relationship between male sexual behavior and intraspecific aggression. It was shown that sexual experience facilitates the display of fighting following gonadectomy and leads to the exhibition of aggression by animals that previously did not fight.…”

Relationship between sexual activity and intraspecific fighting in male mice

Significantly more male mice having cohabited and mated with intact females subsequently displayed intraspecific fighting behavior after castration than males having cohabited with noncycling (ovariectomized) females. Also, intact males that failed to achieve a criterion for aggression during three screening tests subsequently showed a marked increase in fighting after having had copulatory experience relative to males that lived with ovariectomized females. Lastly, spontaneously aggressive males copulated more frequently than nonfighters.

“…The present study reports that exceptionally intense agonistic behavior was engendered by pairing males proximate to a previously inseminated female without sexual access. Although intermale competition is well known in laboratory mice (see, e.g., Brain & Benton, 1983;deCatanzaro, 1999) and female exposure has been shown to stimulate agonistic behavior (deCatanzaro, 1981), the qualities of competition observed here, involving enurination targeted at the opponent, may be unprecedented. A comparable effect has been reported for mature male guinea pigs paired in an enclosure in the presence of an unfamiliar female (Sachser & Lick, 1989;Sachser, Lick, & Stanzel, 1994).…”

Intense arousal of novel male mice in proximity to previously inseminated females: Inactivation of males via chlorpromazine does not diminish the capacity to disrupt pregnancy

et al. 2000

In the course of investigating early pregnancy disruptions by novel males, intense behavioral interactions and chemical emissions were observed among males housed in proximity to inseminated females. These interactions were evident despite wire-mesh separations between males and females. Experiments were designed to examine whether such arousal plays a role in pregnancy disruption. During the fIrst 5 days of pregnancy, inseminated CF-l strain female mice were either left undisturbed or exposed to novel outbred males. Physical separations between males did not diminish the frequency of pregnancy disruption. Subsequently, we investigated whether heavy sedation of novel males via chronic chlorpromazine administration would diminish the capacity to disrupt pregnancy. Pregnancy was disrupted to the same degree in females exposed to drug-treated males and those exposed to alert competing males given vehicle ir\iections. These data show an unprecedented degree of arousal and pheromonal emission among competing males but suggest that these factors are not critical for the capacity to disrupt pregnancy.Novel males can disrupt intrauterine implantation of fertilized ova in various rodents (see,
