Scientists have created a heat-activated metal penis to help men with erectile dysfunction.

Developed by experts at the University of Wisconsin in America, the remote-controlled device lengthens to eight inches when heated to 42C.

Surgically inserted in the base of the penis through an incision, the one inch metal coil can be turned on by a remote held over the groin, generating a metal field which triggers a current.

The coil then warms the implant, making it expand and fully erect.
