It is a safe minimally invasive procedure that reduces vasectomy's already low complication rate. The NSV was developed in China by Dr. Shunqiang Li in 1974 and introduced to the western world by AVSC International and Dr. Marc Goldstein of the New York-Presbyterian Hospital-Cornell Medical Center in 1985. Instead of cutting the scrotal skin, the skin is punctured and the vas id delivered with two special instruments. Over 15 millions men have undergone the NSV procedure worldwide since 1974. It is rapidly becoming the standard vasectomy technique in the United States.
