摘要 目的 比较分析三种来源精子行卵胞浆内单精子显微注射(ICSI)的受精率、卵裂率及临床妊娠结局.方法 选择2004年1月至2009年9月接受ICSI治疗的442个周期资料进行分析,据精子来源的不同参数和数量分为3组:A组为前次常规体外授精(IVF)受精障碍(含精液正常和少弱精子症)49个周期,B组为严重少弱畸形精子症231个周期,C组为睾丸精子组162个周期,比较3组的临床资料和妊娠结局.结果 3组的不孕年限、1PN和3PN受精率、卵裂率、临床妊娠率、流产率比较差异均无统计学意义(P均>0.05).C组较前2组的平均年龄[(30.8±4.1)、(33.6±3.6)、(32.3±4.1)岁]、获卵数[(11.3±5.4)、(7.9±5.4)、(9.9±5.5)个]、优胚率及种植率[64.4%和53.2%、60.5%,31.8%、21.1%、24.7%]差异均有统计学意义(P<0.01,P<0.05).B组2PN率显著高于A组和C组(P均<0.05),分别为78.3%和73.3%、74.9%.结论 不同精子来源ICSI的1PN和3PN受精率、卵裂率、临床妊娠率、流产率无显著差异.睾丸精子组可获得较高的种植率和妊娠率.
