简介：很多时候，在用英语交流时会出现有点儿搞不太懂原意的情况。即使是本族使用者也常常会感到棘手，原因往往在于他们最初在某个语境中学习一个词汇时（错误地）认定它有着特定的用法，而且他们从未直接碰到过一个能够证明其理解有误的情况。有特殊复数形式的单词尤其容易出现这种情况，还有一些因发音或拼写相似或者其意仅有轻微差异的易混淆单词亦是如此。

简介：联系精索静脉曲张的男不孕古典主义地用外科被管理了或帮助了繁殖技术。与在联系精索静脉曲张的不孕作为一个pathophysiological因素增加氧化应力的证据，医药治疗特别抗氧化剂可能与更低的风险成为一种治疗选择。我们在归因于精索静脉曲张的男不孕的管理在各种各样的医药代理人的角色上考察了存在文学。医药治疗典型地与外科对药治疗作为辅助治疗与安慰剂，药对手术的(b)比较，和药的(c)比较处于象二药或一药的(a)比较那样的三种不同状况被评估独自一个。由于数据的异质和进行得好的研究的缺乏，有不够的数据与联系精索静脉曲张的不孕为人推荐医药治疗的平淡的使用，外科仍然是选择的处理。怀孕和实时出生率通常没在精子参数在大多数研究和仅仅的改进被报导或抗氧化剂能力是不够的支持它的平淡的使用。抗氧化剂治疗由于它的理论利益，从现出症状之前的潜的研究的数据，和主要副作用的缺乏是一种潜在的选择。有在精索静脉曲张的外科的修理以后的抗氧化剂的辅助治疗可以改进结果并且是为进一步的研究的一个潜在的区域。
