This report describes the procedure for percutaneous injection of silicone to form plugs in the vas deferens. The injection of 0.1-0.16 ml Chinese-made silicone into 14 men achieved occlusion of a 1-cm length of the vas. Sperm concentrations declined within 1 month of the operation and azoospermia was achieved in all men by 9 months.
