双腔取卵针患者IVF/ICSI-ET结局分析

The outcomes of oocyte retrieval with double lumen ovum aspiration needle in patients underwent in vitro fertilization and embryo transfer(IVF-ET) COH surgery

目的探讨取卵手术中因获卵率低由单腔取卵针改为双腔取卵针患者体外受精-胚胎移植(IVF-ET)结局。方法比较单腔改双腔取卵针(A组,76例)和常规单腔取卵针(B组,76例)患者的促性腺激素(Gn)使用天数、获卵率、合格卵率、受精率、卵裂率、可移植胚胎率、优质胚胎率、胚胎种植率、临床妊娠率、流产率。结果两组患者Gn使用天数、卵胞浆内单精子注射(ICSI)受精率、胚胎种植率、临床妊娠率、流产率比较均无统计学差异(P>0.05)。A组患者获卵率I、VF受精率、卵裂率、可移植胚胎率、优质胚胎率均高于B组。结论对取卵手术中由于获卵率低由单腔改双腔患者,可以考虑放宽ICSI指征以提高受精率。

Objective：To investigate the outcomes of oocyte retrieval with double lumen ovum aspiration needle in patients underwent in vitro fertilization and embryo transfer（IVF-ET） COH surgery.Methods：The outcomes of oocyte retrieval were compared between 76 patients（group A） with double lumen ovum aspiration needle and 76 patients（group B） with single lumen ovum aspiration needle.Results：There was no significant statistical difference in the number of days using Gn,ICSI fertilization rate,embryo implantation rate,clinical pregnancy rate and abortion rate.But oocytes rate,IVF fertilization rate,cleavage rate and transplantable embryo rate,high-quality embryo rate were higher in group A than those in group B（P0.05）.Conclusion：The indications for ICSI may be broadened for improving the fertilization rate in patients who take the double lumen ovum aspiration needle due to the low rate of oocytes retrieval with single lumen ovum aspiration needle.
