Half-ICSI与备早补救ICSI在可疑体外受精周期失败中的应用

目的:比较half-ICSI与备早补救ICSI 2种授精方式在体外受精周期中的应用价值。方法:选取可疑受精失败的不孕患者,随机分为half-ICSI组(A组,half-ICSI授精,138个周期)和行备早补救ICSI组(B组,行备早补救ICSI授精,112个周期)。分析受精率、胚胎质量、种植率和妊娠率。结果:A组与B组的正常受精率分别为65.37%和70.78%,多精受精率分别为1.59%和3.08%,优质胚胎率分别为66.76%和73.75%,胚胎种植率分别为26.64%和35.59%,组间均有统计学差异(P<0.05);妊娠率分别为46.09%和57.84%,组间无统计学差异(P>0.05)。其中在IVF受精成功周期中,A组的优质胚胎率、胚胎种植率和临床妊娠率均明显低于B组(P<0.05);而在IVF受精失败周期中,ICSI的优质胚胎率、胚胎种植率和临床妊娠率A、B组间均无差异(P>0.05),但A组的受精率显著低于B组(P<0.01)。结论:备早补救ICSI授精方式优于half-ICSI授精方式,但有增加多精受精的风险。

Half-ICSI and Preparation of Early Rescue ICSI:Two Insemination Methods to Prevent Fertilization Failure

Objective: To compare the outcome of two insemination methods to prevent fertilization failure: half-ICSI and preparation of early rescue ICSI.Methods: A total of 250 IVF cycles of patients with primary infertility,whose tubal were not completely obstructed,enrolled in the study.They were random dievied into group A(n=138 cycles,received half-ICSI) and group B(n=112 cycles,received preparation of early rescue ICSI).Fertilization and cleavage rate,embryo quality,implantation rate and pregnancy rate were the ...
