Booty calls are making your penis unhappy:
A new study shows a worrying link between poor sperm and the number of hours a day that a man uses his mobile phone.
The findings suggest millions of men may encounter difficulties in fathering a child due to the widespread use of mobile phones and offers another possible explanation for plummeting fertility levels among British males.
Men who used a mobile for more than four hours a day had a 25 per cent lower sperm count than men who never used a mobile.
The men with highest usage also had greater problems with sperm quality, with the swimming ability of sperm – a crucial factor in conception – down by a third.
They had a 50 per cent drop in the number of properly formed sperm, with just one-fifth looking normal under a microscope.
