Abstract
Abstract A male contraceptive device which comprises a plug having a coating of fabric on its outer walls. The plug is inserted in the vas deferens. The fabric coating allows for the ingrowth of cells from the wall of the vas deferens into the fabric. This provides for complete occlusion of the vas deferens to prevent passage of the sperm therethrough.
