  text: Conflict over reproduction between females and males exists because of anisogamy
    and promiscuity. Together they generate differences in fitness optima between
    the sexes and result in antagonistic coevolution of female and male reproductive
    traits. Mounting duration is likely to be a compromise between male and female
    interests whose outcome depends on the intensity of sexual selection. The timing
    of sperm transfer during mounting is critical. For example, mountings may be interrupted
    before sperm is transferred as a consequence of female or male choice, or they
    may be prolonged to function as mate guarding. In the highly promiscuous intertidal
    snail Littorina saxatilis, mountings vary substantially in duration, from less
    than a minute to more than an hour, and it has been assumed that mountings of
    a few minutes do not result in any sperm being transferred. Here, we examined
    the timing of sperm transfer, a reproductive trait that is likely affected by
    sexual conflict. We performed time-controlled mounting trials using L. saxatilis
    males and virgin females, aiming to examine indirectly when the transfer of sperm
    starts. We observed the relationship between mounting duration and the proportion
    of developing embryos out of all eggs and embryos in the brood pouch. Developing
    embryos were observed in similar proportions in all treatments (i.e. 1, 5 and
    10 or more minutes at which mountings were artificially interrupted), suggesting
    that sperm transfer begins rapidly (within 1 min) in L. saxatilis and very short
    matings do not result in sperm shortage in the females. We discuss how the observed
    pattern can be influenced by predation risk, population density, and female status
    and receptivity.
