Twenty years ago Clemens Bimek, a German carpenter, became intrigued with the possibility of preventing conception by impeding the flow of sperm with an on/off switch attached inside a man's body to the vas deferens.

In contrast to a traditional vasectomy, however, the valves envisioned could be opened again.
