Vasectomy is simply a process of accessing the vasa (the tubes that carry sperm from the testes), and dividing these tubes. Traditionally in the United States, the vas tubes were accessed by cutting into the scrotum with a scalpel. During the 1970s in China, Dr. Shunqiang Li developed a more gentle technique using a very fine tool to access the tubes through a tiny puncture. This no-scalpel technique has been shown to have fewer complications and most patients find the method to be surprisingly gentle. During residency, Dr. Curington learned a modified Li No-Scalpel technique, and then traveled around the world and studied abroad to improve his technique. Since then, Dr. Curington has continued working to optimize the procedure for his patients, including publishing scholarly articles on contraception and vasectomy and teaching other physicians.
