摘要 目的通过在纺锤体观察仪下行卵胞浆内单精子注射(ICSI),比较不同纺锤体观察情况的卵母细胞的ICSI结局。方法 2014年2~5月间,就诊于我中心的反复IVF失败、获卵数较少、高龄妇女、卵母细胞质量较差、胚胎发育差而导致可移植胚胎数少或者无可移植胚胎的患者30例,在纺锤体观察仪下行ICSI操作。观察卵母细胞受精情况和胚胎发育情况,并比较观察到纺锤体组和未观察到纺锤体组胚胎的正常受精率、异常受精率、总受精率、卵裂率、可移植胚胎率和优质胚胎率。结果 30例行ICSI助孕的患者,共获卵149枚,其中MII卵118枚;72枚MII卵观察到纺锤体,纺锤体观察率为61.01%;观察到纺锤体组和未观察到纺锤体组卵母细胞的总受精率(94.44%vs.80.43%)、正常受精率(83.33%vs.54.35%)、异常受精率(11.11%vs.26.09%)均有统计学差异(P〈0.05);未观察到纺锤体组胚胎的卵裂率、可移植胚率和优质胚胎率低于观察到纺锤体组,但均无统计学差异(P〉0.05)。结论 ICSI授精时观察到纺锤体的卵母细胞受精结果优于未观察到纺锤体的卵母细胞;使用纺锤体观察仪进行ICSI有助于避免纺锤体损伤,进而改善受精结局。
