Vasal sterilization in China.
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.
