Underpants woven with silver wire to block mobile phone radiation are being sold to men who are scared their phone use is hurting their chances of becoming a dad.
German students have created a pair of boxer-style undies with silver wire to block electro-magnetic radiation from getting to a man’s private parts and ultimately lowering their sperm count.
The Munich Business School inventors designed Kronjuwelen – or “crown jewels” – underwear, which are machine washable and for sale on Amazon for £23.
Peer-Boy Matthiesen, 34, Daniel Herter, 31, Nick Piepenburg, 31, and Berno Delius, 31, came up with the idea after some of their friends had trouble conceiving.
“We became aware of the topic because we were thinking about becoming fathers ourselves and we saw in our friendship network that some of them were having trouble making babies,” Nick tells Mashable.
The fabric prevents 98 per cent of mobile phone radiation.
But Dr Simon Mann, of Public Health England’s Centre for Radiation, Chemical and Environmental Hazards, tells Mashable there is no scientific evidence that exposure from mobile phones affects human health “at exposure levels below internationally agreed guidelines”.
The invention comes after a recent Israeli study found that men who are heavy phone users also have lower sperm counts. The study involved a sample of 106 men, each of whom had already been referred by doctors for having reproductive issues.
