摘要 目的探讨精子DNA碎片指数(DFI)对体外受精-胚胎移植(IVF-ET)妊娠结局的影响。方法回顾性分析2016年1月至2020年12月于本院行长方案/改良长方案促排卵IVF-ET患者的1079个取卵周期(1441个移植周期)的临床资料。根据男方精子DFI不同将患者分为3组:A组(DFI≤15%,845个周期)、B组(15%<DFI<30%,200个周期)和C组(DFI≥30%,34个周期);并根据女方年龄分为<35岁和≥35岁进行分层分析。比较各组患者的正常受精率、优质胚胎率、囊胚形成率、优质囊胚率、种植率、临床妊娠率和活产率。结果取卵周期中,当女方年龄≥35岁时,C组患者正常受精率(54.55%)显著低于A组(68.76%)和B组(69.03%);3组间优质胚胎率、囊胚形成率和优质囊胚率无显著性差异(P>0.05);当女方年龄<35岁时,B组(17.53%)、C组(11.82%)的优质囊胚率显著低于A组(21.36%)(P<0.05)。移植周期中,不同年龄各DFI组的种植率、临床妊娠率和活产率均无显著性差异(P>0.05)。结论DFI对不同年龄女性患者IVF-ET的结局可能存在一定影响,但其对临床妊娠率和活产率等的影响较为有限。
