The influence of the social rank of male mice, determined by the outcome of fights, was assessed on their growth, treadmill performance, open‐field behavior, and morphometric traits. Fertility of mated females was also investigated. Special attention was paid to the relationship between the male's social rank and body weight. Winners of fights were heavier than losers; their latencies were shorter, and they showed more locomotor activity in an open field test. Winners also had higher absolute testicular and epididymal weights. These males had a positive influence on the reproductive fitness of the females with which they were mated.
