摘要:本研究旨在比较三种检测精子DNA碎片(sDF)的方法——缺口末端标记试验(TUNEL)、吖啶橙流式细胞术(AO FCM)和精子染色质扩散试验(SCD)的检测效果,并分析其相关性。研究对象为72例男性患者,分别采用TUNEL、AO FCM和SCD方法对其精子DNA碎片进行检测。根据精子DNA碎片指数(DFI)结果,将样本分为三组:低碎片率组(组1,DFI <15%)、中等碎片率组(组2,DFI 15%~30%)和高碎片率组(组3,DFI >30%)。研究结果显示,三种检测方法在总体上对精子DNA碎片的分析结果无显著差异。但在低碎片率组(DFI <15%)中,SCD方法检测的DFI结果(7.3±3.0)低于TUNEL方法检测结果(8.1±3.7);在中等碎片率组(DFI 15%~30%)中,AO FCM方法检测的DFI结果(19.9±4.4)低于TUNEL方法检测结果(20.5±4.4)。
