  • 简介:因为输精管切除术的不可避免的复杂并发症,这研究被承担与一个微型外科的方法与没有解剖刀输精管切除术(NSV)相比植入进管腔的一台nonobstructiveintravas设备(IVD)估计男消毒的功效和安全。IVD被分成二种类型:而,IVD-B让一条尾巴使用了修理到管deferens(固定翅膀)IVD--A不做。multicenter未来的使随机化的控制临床的审判在中国被进行。学习由寻求输精管切除术的1459个男志愿者组成随机被分到IVD--一(n=487),IVD-B(n=485)或NSV(n=487)组并且经历了操作。包括的后续在3rd-6th和12th手术后的月。对这些题目的评价包含了常规物理考试(包括的将军和andrological考试)和精液分析。subjects’;搭挡们也经历了监视因为由月刊的怀孕关于月经会见,如果必要,尿测试。处于怀孕率没有重要差别(0.65%为IVD--一,0为IVD-B并且0.21%为NSV)在三个组之中(P>;0.05)。在12th手术后的月分别地在三个组是零,0.9%和1.7%。在结论,IVD男消毒展出长期的不利事件的低风险并且被发现作为一个男消毒方法有效,类似于NSV技术。IVD男消毒被期望是一个新奇避孕方法。
