Vasal sterilization has become the most popular method of contraception in many countries since the 1960's. In China, an estimated 30 million men have undergone voluntary sterilization. There have been two major developments in vasectomy technique, the no-scalpel method and the percutaneous chemical vas occlusion. These methods have significantly increased the acceptability of male sterilization in some cultures since no incisions in the skin are required. The effective rate is over 98% for both methods. The clients experience less pain, fewer complications and more rapid recovery. Epidemiological studies of large numbers of volunteers receiving no-scalpel or chemical vas occlusion procedures have resulted in a clearer picture of their safety, effectiveness, simplicity and economy. Meanwhile, some promising reversible vasal sterilization techniques have also been studied.
自20世纪60年代以来，输精管绝育术已成为许多国家最受欢迎的避孕方法。在中国，估计有3000万男性接受了自愿绝育手术。输精管切除术技术有两项重大进展，即无手术刀方法和经皮化学性输精管闭塞术。由于无需在皮肤上切口，这些方法在某些文化中显著提高了男性绝育术的可接受性。两种方法的有效率均超过98%。受术者疼痛较轻、并发症较少且恢复较快。对大量接受无手术刀或化学性输精管闭塞术的志愿者进行的流行病学研究，使人们对其安全性、有效性、简易性和经济性有了更清晰的认识。与此同时，一些有前景的输精管绝育可逆技术也得到了研究。
