Abstract
- A new technique of immediate sperm clearance has been developed by killing and irrigating residual sperm in the distal ductal system following vasectomy with a spermicidal solution at the time of the operation. For this, biochemical study, histologic study, and clinical study were conducted ,and by this, the need for postoperative contraception, and the need for postoperative semen testing were eliminated. Among the various spermicidal solutions such as tap water, distilled water,KMnO4,acetic acid, lactic acid, rivanol, alcohol, the KMnO4 solution has been proved to be the most suitable for the spermicidal solution, through biochemical study and histologic study. About 10ml of the KMnO4 solution,0.5% were injected into the distal ductal system under pressure, and killed redisual sperm immediately after the application. Number of redisual sperm in the distal ductal systems was significantly reduced by the KMnO4 application. No complication nor harmful effects could be observed after the procedure.
