Develped in China in 1974, the No-Scalpel-Vasectomy was introduced to the United States in 1985. Since then, a much higher percentage of men have been willing to have a vasectomy as a means of permanent contraception. There is something about the idea of surgery on one’s scrotum that tends to squelch men’s enthusiasm for taking over the task of birth control. To the degree that less invasive approaches are introduced, more and more men will be willing to take responsibility for contraception in their relationships.
