研究了延迟交配对小鼠着床前胚胎（78 +/- 1小时）的影响，通过设置不同的交配时间与估计的自然排卵时间有关。甚至在夜间自然排卵后的上午晚些时候和下午早些时候也会发生交配。然而，在下午早些时候交配的雌性在剖腹手术时没有存活的胚胎。虽然在估计排卵后6或10小时交配的各组胚胎发育不受影响，但这些组中退化胚胎的百分比有所增加。这些结果表明，排卵和交配时间间隔的延长对着床前胚胎有一定的有害影响。
The effects of delayed mating on mouse preimplantation embryos (78 +/- 1 hours) were studied by setting up different mating periods in relation to the estimated time of spontaneous ovulation. Copulation occurred even in the late morning and early afternoon after the night of spontaneous ovulation. However, females mated in the early afternoon had no viable embryos at the time of laparotomy. Although embryonic development was not affected in the groups mated 6 or 10 hours after estimated ovulation, the percentage of degenerated embryos was increased in these groups. These results suggest that prolonged intervals between the estimated time of ovulation and mating have some deleterious effects on preimplantation embryos.
