Phones in pockets may harm male fertility

Scientists at the University of Exeter said their work suggested that exposure to radiofrequency electromagnetic radiation from mobile phones negatively affected sperm quality – but further research was needed.

Previous studies have suggested that radiofrequency electromagnetic radiation (RF-EMR) emitted by the devices can have a detrimental effect on male fertility.

Most of the global adult population own mobile phones, and around 14% of couples in high and middle income countries have difficulty conceiving.

A team led by Dr Fiona Mathews, of the University of Exeter, conducted a systematic review of the findings from 10 studies, including 1492 samples, with the aim of clarifying the potential role of this environmental exposure.

Participants in the studies were from fertility clinics and research centres, and sperm quality was measured in three different ways: motility, viability and concentration.

In control groups, 50
