Men could be inadvertently damaging their chances of becoming a father by keeping a mobile phone in their trouser pocket, a new study suggests.
Exposure to radio-frequency electromagnetic radiation from mobiles negatively affected sperm quality, according to scientists at the University of Exeter, who also admitted further research was needed.
Previous studies have suggested that radio-frequency electromagnetic radiation emitted by the devices can have a detrimental effect on male fertility.
Dr Fiona Mathews, of the University of Exeter, who led the study, said: "This study strongly suggests that being exposed to radio-frequency electromagnetic radiation from carrying mobiles in trouser pockets negatively affects sperm quality.
"This could be particularly important for men already on the borderline of infertility, and further research is required to determine the full clinical implications for the general population."
