Fertilization and pregnancy rates in an in vitro fertilization and embryo transfer program were studied after a range of insemination times of between 1 and 26 hours after oocyte recovery. There was no significant variation in fertilization rate across this range. The pregnancy rate showed no significant variation for insemination between 3 and 16 hours after aspiration. However, it was disappointing at 2 hours (3%), and no pregnancies were achieved from the nine patients whose ova were inseminated 20 or more hours after aspiration. It is concluded that mature oocytes can be inseminated in vitro at any time between 3 and 16 hours after aspiration and still retain the same potential to produce a pregnancy.
在卵母细胞回收后的1至26小时内，对一系列不同授精时间的体外受精和胚胎移植项目中的受精率和妊娠率进行了研究。在此范围内，受精率没有显著差异。抽吸后3至16小时进行授精，妊娠率没有显著差异。然而，2小时时的妊娠率令人失望（3%），抽吸后20小时或更长时间进行卵子授精的9名患者均未怀孕。结论是，成熟卵母细胞在抽吸后3至16小时之间的任何时间进行体外授精，仍具有相同的妊娠潜力。
