Introducing the sperm switch.
The Bimek SLV, an invention by Clemens Bilek, is a device that would stop sperm from mixing with semen prior to ejaculation.
In effect, this device would serve as a contraceptive switch, allowing couples to have sex with a lower risk of pregnancy.
The device is a valve that sits on the spermatic duct (which sounds incredibly painful), and a valve switch that can be toggle on and off beneath the scrotum skin (which sounds equally painful). The device is made from the same material in dental and cranial implants.

According to Mashable, Bimek’s device is not yet officially approved, but he is hoping that it will be approved after clinical trials. The current plan is for the device to be available by 2018, for a surgery that would cost between $5,000-$6,000.
