体外受精 (IVF) 和胚胎移植 (ET) 的成功取决于优化最终导致胚胎替换的程序每个步骤的效率。通过各种卵巢刺激方案、卵母细胞抽吸技术和细胞培养技术，人们做出了大量努力来改善卵母细胞的恢复和受精。这使得卵母细胞回收率达到 80-90%，胚胎移植率达到 60-70%。1-4 相比之下，ET 后的妊娠率低得令人失望，仅为 15% 到 20%。1,2,5,6 这似乎是大多数 IVF 失败发生的步骤。
The success of in vitro fertilization (I VF) and embryo transfer (ET) is dependent upon optimizing the efficiency of each step of the procedures that finally lead to embryo replacement. Much effort has been directed at improving oocyte recovery and fertilization through various regimes of ovarian stimulation, oocyte aspiration techniques, and cell culture technology. This has led to rates of oocyte recovery in the region of 80–90% and embryo transfer rates of 60–70%.1–4 By contrast, the pregnancy rate following ET is disappointingly low, being of the order of 15 to 20%.1,2,5,6 This seems to be the step at which most failures of IVF occur.
