【摘要】 目的比较常规IVF授精后4h和20h补行卵胞浆内单精子注射(rescue ICSI)的效果。方法回顾分析2006年1月-2007年12月在我院生殖医学中心接受常规IVF治疗的21例非男性因素不育患者,授精后4h行补救ICSI,并与另组实施的18个常规IVF授精后20h行补救ICSI周期进行比较。结果 4h补救ICSI组的受精率为76.3%,高于20h补救ICSI组(53.0%),有统计学意义(P<0.05)。4h补救ICSI组中11例临床妊娠(52.3%),其中2个双胎,8个单胎和一个流产。而20h补救ICSI组无一例妊娠。结论和授精后20h行补救ICSI相比,授精后4h行补救ICSI可以获得较好的受精率、妊娠率和种植率。更多还原
