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.
通过设置与估计的自然排卵时间相关的不同交配期，研究了延迟交配对小鼠植入前胚胎（78±1小时）的影响。即使在自然排卵后的深夜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小时交配的组中胚胎发育没有受到影响，但这些组中退化胚胎的百分比增加了。这些结果表明，估计的排卵时间与交配之间的间隔延长对植入前胚胎有一些有害影响。
