摘　　要：目的探索氩离子(Ar+)激光凝堵人类输精管的作用机制,观察临床应用效果。方法62名成年已婚且有2～3个子女的健康男性志愿者为研究对象,采用Ar+激光照射的方法进行输精管凝堵。对前4例受试对象切开阴囊皮肤,直视下进行激光照射,其余58例受试对象经皮穿刺进行体内照射。通过精液化验,观察精子减少速度及消失时间。结果60例受试对象被照射6个月后精子数减为0,2例因照射剂量不足而失败。结论Ar+激光是用于输精管凝堵的较为理想的光源之一,能较好地凝堵输精管且基本无并发症和后遗症。Objective To study the effect of Ar+ laser on human vas deferens and to compare the effects of using different radiation levels with varying thickness of tissue and varying levels of injury. Methods After initial tests on animals, four human scrotums were opened and treated directly with Ar+ laser radiation. Then 58 human individual scrotums were treated with radiation by the method of trans-skin puncture. The rate of sperm reduction and elimination was tested. Results In 60 cases, the sperms were found to be eliminated completely after six months of radiation treatment. In 2 cases the sperms were found not to be eliminated completely due to the insufficient radiation. Conclusion Ar+ laser is one of the best forms of radiation for coagulation of vas deferens. It can be used to coagulate vas deferens without any complications or sequelae.
