    Summary
    Mating plugs increase a males' paternity share in competition against rival males. In many animals, males plug the female reproductive tract after mating, supposedly to prevent females from remating. We show that male mice are strongly limited in plug-producing ejaculate components. Variation in plug size did not predict female remating, but influenced competing males' competitive fertilization success when remating occurred.
