摘要 目的研究体外受精-胚胎移植(IVF-ET)中短时受精对高龄女性助孕结局的影响。方法回顾性分析行IVFET的高龄女性(年龄≥35岁),共227个周期,按精卵混合时间分为两组:短时受精组541个卵子行短时受精(精卵混合2 h),常规受精组1 677个卵子行常规受精(精卵混合约16~20 h)。比较两组女性的受精率、胚胎质量及妊娠率,并进行统计分析,评估短时受精对高龄女性助孕结局的影响。结果短时受精组与常规受精组患者的基本情况、完全不受精率和受精率〈30%的周期率比较差异均无统计学意义(P〉0.05)。短时受精组的优质胚胎率为87.19%(177/203),显著高于正常受精组的61.35%(600/978),差异有统计学意义(P〈0.05)。短时受精组的种植率及临床妊娠率均稍高于常规受精组,但差异均无统计学意义(P〉0.05)。结论患者年龄≥35岁时,IVF-ET短时受精可明显提高优质胚胎率,改善助孕结局。
