目的探讨在常规IVF-ET受精失败后补救ICSI和短时受精后补救ICSI两种方法在临床中的应用。方法选择常规IVF中受精失败的20个周期行晚期补救ICSI,26个周期行短时受精后补救ICSI,两种方法进行比较。结果早期补救的2PN的受精率,种植率,妊娠率分别为85.28%,13.64%,29.63%,明显高于晚期补救ICSI的50.27%,5%,15.79%(P<0.01)。结论早期补救ICSI较晚期补救ICSI的2PN的受精率,种植率,妊娠率高,能更好的改善妊娠结局。
Objective To investigate the clinical application of ICSI after salvage of conventional IVF-ET fertilization and salvage ICSI after short-term fertilization. Methods 20 cycles of routine fertilization failure in routine IVF were selected, ICSI was performed in late stage, ICSI was administered in 26 cycles after short-term fertilization, and the two methods were compared. Results The rates of fertilization, implantation and pregnancy of 2PN were 85.28%, 13.64% and 29.63%, respectively, which were significantly higher than those of ICSI 50.27%, 5% and 15.79% (P <0.01). CONCLUSION: The 2PN with ICSI of early recovery ICSI is better in fertilization, implantation rate and pregnancy rate, which can better improve the outcome of pregnancy.
