1未处理或上游法处理后精子的DNA碎片能否预测使用赠卵ICSI后的妊娠?显示文摘本研究比较了未处理的精子和上游法处理后精子中的DNA碎片值(SDF)预测使用赠卵ICSI后妊娠的可能性。总共81例不孕女性接受通过夫精和赠卵ICSI后的胚胎移植。这种方式排除了目前公认的影响精子DNA修复的女方因素。在ICSI受精时,同时使用DNA碎片率检测试剂盒(Halosperm)进行盲法检测未处理的和上游法处理后精液中的精子DNA碎片。经上游法处理后的精液样本中SDF值呈显著下降。有趣的是,未处理的或上游法处理后精液样本中的SDF值均能预测妊娠。通过ROC曲线和其衍生的约登指数计算得出未处理前和上游法处理后精子sDF的临界值分别是24.8%和17.5%。未处理精子SDF预测妊娠的敏感性和特异性分别为75%和69%,而上游法处理后的精子SDF预测妊娠的敏感性和特异性分别是78%和73%。虽然SDF值增高与生育呈负相关,但我们发现在精子筛选降低sDF值后再与赠卵进行ICSI并不能保证获得妊娠。这表明目前的技术手段对于一些DNA损伤仍无法探及,从而相对影响辅助生殖成功的机率。因此,我们认为对目前的“冰山模式”作一些修饰后可以用来解释SDF在生育中的作用。Jaime Gosálvez Pedro Caballero Carmen López-Fernández Leonor Ortega José Andrés Guijarro José Luís FernAndez Stephen D Johnston Rocio Nufiez-Calonge 2013Asian Journal of Andrology2013,15,6:3
