Sperm DNA fragmentation has been associated with reduced fertilization rates, embryo quality, pregnancy rates and increased miscarriage rates. Various methods exist to test sperm DNA fragmentation such as the sperm chromatin structure assay (SCSA), the sperm chromatin dispersion (SCD) test, the terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labelling (TUNEL) assay and the single cell gel electrophoresis (Comet) assay. We performed a systematic review and meta-analysis to assess the value of measuring sperm DNA fragmentation in predicting chance of ongoing pregnancy with IVF or ICSI. Out of 658 unique studies, 30 had extractable data and were thus included in the meta-analysis. Overall, the sperm DNA fragmentation tests had a reasonable to good sensitivity. A wide variety of other factors may also affect the IVF/ICSI outcome, reflected by limited to very low specificity. The constructed hierarchical summary receiver operating characteristic (HSROC) curve indicated a fair discriminatory capacity of the TUNEL assay (area under the curve (AUC) of 0.71; 95% CI 0.66 to 0.74) and Comet assay (AUC of 0.73; 95% CI 0.19 to 0.97). The SCSA and the SCD test had poor predictive capacity. Importantly, for the TUNEL assay, SCD test and Comet assay, meta-regression showed no differences in predictive value between IVF and ICSI. For the SCSA meta-regression indicated the predictive values for IVF and ICSI were different. The present review suggests that current sperm DNA fragmentation tests have limited capacity to predict the chance of pregnancy in the context of MAR. Furthermore, sperm DNA fragmentation tests have little or no difference in predictive value between IVF and ICSI. At this moment, there is insufficient evidence to recommend the routine use of sperm DNA fragmentation tests in couples undergoing MAR both for the prediction of pregnancy and for the choice of treatment. Given the significant limitations of the evidence and the methodological weakness and design of the included studies, we do urge for further research on the predictive value of sperm DNA fragmentation for the chance of pregnancy after MAR, also in comparison with other predictors of pregnancy after MAR.
精子DNA碎片化与受精率降低、胚胎质量下降、妊娠率降低以及流产率增加有关。存在多种检测精子DNA碎片化的方法,如精子染色质结构分析(SCSA)、精子染色质扩散(SCD)试验、末端脱氧核苷酸转移酶介导的脱氧尿苷三磷酸缺口末端标记(TUNEL)分析和单细胞凝胶电泳(彗星)分析。我们进行了一项系统综述和荟萃分析,以评估测量精子DNA碎片化在预测体外受精(IVF)或卵胞浆内单精子注射(ICSI)后持续妊娠机会方面的价值。在658项独特研究中,30项有可提取的数据,因此被纳入荟萃分析。总体而言,精子DNA碎片化检测具有合理至良好的敏感性。各种各样的其他因素也可能影响IVF/ICSI结果,这表现为特异性有限至极低。构建的分层汇总接受者操作特征(HSROC)曲线表明,TUNEL分析(曲线下面积(AUC)为0.71;95%可信区间为0.66至0.74)和彗星分析(AUC为0.73;95%可信区间为0.19至0.97)具有一定的鉴别能力。SCSA和SCD试验的预测能力较差。重要的是,对于TUNEL分析、SCD试验和彗星分析,荟萃回归显示IVF和ICSI之间的预测价值没有差异。对于SCSA,荟萃回归表明IVF和ICSI的预测价值不同。本综述表明,目前的精子DNA碎片化检测在预测男性因素相关(MAR)情况下的妊娠机会方面能力有限。此外,精子DNA碎片化检测在IVF和ICSI之间的预测价值几乎没有差异。目前,没有足够的证据推荐在接受MAR的夫妇中常规使用精子DNA碎片化检测来预测妊娠和选择治疗方法。鉴于证据的重大局限性以及纳入研究的方法学弱点和设计问题,我们强烈敦促进一步研究精子DNA碎片化对MAR后妊娠机会的预测价值,也与MAR后妊娠的其他预测因素进行比较。
