【摘要】：目的:探讨精子顶体酶检测对不明原因不孕(UI)夫妇选择助孕治疗方案的临床意义。方法:回顾性分析2013年1月至2015年12月诊断为UI,并经3次宫腔内人工授精(IUI)治疗失败改行体外受精-胚胎移植(IVF-ET)助孕的49对夫妇共49个周期的临床资料,并对比分析同期因输卵管阻塞因素行常规IVF治疗的95对夫妇的131个周期的临床资料,比较两组实验室数据、临床结局和顶体酶活性差异;进一步根据UI夫妇男方精子顶体酶活性将UI组分成2个亚组:36 IU/106精子组共20个周期,≥36 IU/106精子组共29个周期,比较两亚组之间受精率的差异。结果:1行IVF-ET治疗的UI夫妇,比同期因输卵管阻塞行常规IVF的夫妇受精率显著下降(67.0%vs 76.4%,P0.05),补救性卵细胞胞质内单精子注射(ICSI)率高于输卵管因素组(20.4%vs 6.1%,P0.05);成熟卵母细胞比例(MII卵率)、可利用胚胎率、优胚率、种植率、临床妊娠率两组差异无统计学意义(P0.05)。2UI组中位精子顶体酶活性低于输卵管因素组(36.03 IU/106精子vs 61.98 IU/106精子,P0.01),UI组中顶体酶活性36 IU/106精子亚组的受精率明显低于顶体酶活性≥36 IU/106精子亚组的受精率(47.7%vs80.3%,P0.01)。结论:1UI夫妇男方精子顶体酶活性低下导致的受精率低,可能是造成女性不孕的主要原因和潜在因素。2鉴于UI夫妇男方精子顶体酶活性36 IU/106精子时受精率较低,建议不采用IUI治疗,可选择IVF+短时受精联合早期补救ICSI治疗。
[Abstract]:Objective: to investigate the clinical significance of sperm acrosin detection in the choice of assisted pregnancy therapy for couples with unexplained infertility. Methods: the diagnosis of UI from January 2013 to December 2015 was retrospectively analyzed and treated by intrauterine artificial insemination with IUI 3 times. Clinical data of 49 couples with IVF-ET-assisted pregnancy in 49 cycles. The clinical data of 131 cycles of 95 couples who received routine IVF therapy due to tubal obstruction were analyzed, and the clinical data, clinical outcome and acrosin activity were compared between the two groups. The UI group was further divided into 2 subgroups: 36 IU/106 sperm group for 20 cycles and 鈮，
