两种男性绝育方法的比较研究

A COMPARATIVE STUDY OF TWO METHODS FOR MALE STERILIZATION

对108例直视钳穿法输精管结扎术和105例输精管注射粘堵术进行对比研究，结果术后2年精子消失率分别为96．19％和93．20％，并发症发生率分别为1．90％和2．91％，经统计学处理，两者无显著性差异。表明该两种绝育方法都是有效和安全的男性绝育方法。对其中10例进行了显微外科输精管吻合术，术后3个月，前者吻合2例全部复通，其中1例妊娠；后者吻合8例，7例复通，2例妊娠。

The comparative study on 108 cases of no - scalpel va-sectomy (NSV) and 105 cases of Chemical vas occlusion(CVO) two years after the procedure show that the spermdisappearane rate and complication rate for NSV were 96.19% and 1. 90% while the rates for CVO were 93. 20%and 2.91 % respectively. There was no statishcally signifi-cant differences in the rates between two groups (P > 0.05). It is suggested that both NSV and CVO are safe, effective methods for male sterilization. Vasovasotomy with mi-crosurgical technique for 10 cases out of 213 were followed upthree months after reversal.On 2 cases of NSV,the sperm was observed in their semen and one case's wife wes pregnent.The other 8 cases of CVO, the sperm was observed in 7cases and 2 cases' wife were pregnent.
