Scientists have developed an
eight-inch remote-controlled metal penis that may help men struggling with
severe erectile dysfunction. Developed by researchers from the University of
Wisconsin in the US, the heat-activated device can be used at the press of a
button in just two minutes. The implant will help revive the sex lives of
people who fail to respond to drugs like Viagra or other treatments, experts
say. The implant is made from nitinol – also known as “memory metal” – which is
a mixture of nickel and titanium. It can change shape when heated or cooled The
Sun reported, at body temperature of 37°C, the implant is just a couple of
inches long. However, when heated to 42°C, it expands to eight inches. A shape
memory alloy-based penile prosthesis represents a promising new technology in
the treatment of erectile dysfunction. Surgeons can make a tiny incision at the
bottom of the penis and insert the implant – made from stretchy latex covered
with a coating of memory metal. Attached to one end is a tiny heating coil. The
soil 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. A cool flannel makes the swelling go down.
