目的探讨Nd:YAG激光输精管节育的效果及安全性。方法用自制的Nd:YAG激光节育机,对150只兔施行了输精管激光照射堵塞试验,并对953例输精管激光节育者的效果和安全性进行了跟踪观察。结果兔(40W×1S)秒组达到阈损伤,该组存活兔输精管堵塞率100%;人精子消失率99.4%。结论Nd:YAG激光输精管节育法安全可靠,避免了开放手术并发症,为男性提供了一种可供选择的非手术节育新方法。
Objective To investigate the efficacy and safety of Nd: YAG laser vas deferens. Methods A self-made Nd: YAG laser machine was used to test the effect of 1503 vasectomy laser gunshot wounds on the efficacy and safety of 953 rabbit vasectomies. Results The rabbits (40W × 1S) sec group reached the threshold lesion. The vasectomy rate of surviving rabbits in this group was 100%. The disappearance rate of human sperm was 99.4%. Conclusion Nd: YAG laser vas deferens is safe and reliable, avoids the complications of open surgery and provides a new alternative to non-surgical birth control for men.
