Zusammenfassung:Estrous female voles ( Microtus montanus) received (a) no copulation, (b) one ejaculatory series, (c) two ejaculatory series, or (d) more than two series. Copulation was shown to be essential for ovulation, and increasing amounts of copulatory stimulation were demonstrated to increase the probability of ovulation. Only 25% of females receiving one ejaculatory series ovulated, whereas 100% of those receiving more than two series ovulated. Thus, multiple ejaculations play an important role in successful reproduction in this species.
