The intra vas device, analogous to the intrauterine device (IUD) for women, is meant to be a reversible alternative to a vasectomy. The device consists of a set of flexible, hollow silicone plugs, each about a millimetre in diameter and 2.5 cm long. The IVDs are inserted into the vas deferens and block the flow of sperm from the testes to the seminal glands.
The FDA approved human trials for the intra-vas device in 2006.
