摘要:
目的 了解辅助生殖技术(ART)治疗后孕早期自然流产的绒毛细胞染色体的异常情况,为优生优育工作作指导.方法 选择行体外受精-胚胎移植(IVF-ET)、单精子卵胞浆内显微注射( ICSI)、冻融胚胎移植(F-ET)及宫腔内人工授精(IUI)治疗后的自然流产绒毛标本41例,进行绒毛细胞培养及G显带,分析染色体核型.结果 41例标本中有30例培养成功,绒毛染色体异常15例,占50%.多数为数目异常,其中X单体1例,染色体三体11例(包括18三体1例,16三体3例,15三体2例,4号三体1例,9号三体1例,2号三体1例,嵌合体型21三体2例),多倍体1例,具有额外小染色体的核型1例.结论 ART妊娠流产与胚胎染色体异常关系密切,非整倍体是导致ART治疗后自然流产的重要原因.
