Description: This product is a mesh-like vas deferens plug that intentionally allows subfertile levels of sperm to pass through it to reduce the buildup of pressure in the epididymis. The plug is made of flexible synthetics and anchored to the vas wall with a suture. Two very small holes near its tip allow some sperm to pass through. There is also a version with copper.
