Remote-controlled Cojones to Replace Vasectomy

British scientists are at work on a man that can be turned on and off ... and we're not talking about a new, super hi-tech model of the Rabbit. A remote-controlled testicular implant could be the next viable alternative to vasectomy, with a valve-like implant that would allow dudes to turn the flow of their sperm on and off at the touch of a button. (Ladies, a new way to become "accidentally" preggers!) At its best, the device could help prevent all those annoyingly blissful celebrity pregnancies. But we're not holding our breath: The day we see it stop Kevin Federline's potent man jam, is the day we'll start to believe.
