Men who keep their phone in their trouser pocket risk reducing their sperm quality, a study suggests.
Talking on your phone while it's charging, or keeping it as far as two-feet from you as you sleep can also make your swimmers sluggish.
Martha Dirnfeld, who conducted the study at Technion University in Haifa, Israel, said: "We analysed the amount of active swimming sperm and the quality and found that it had been reduced.

"We think this is being caused by a heating of the sperm from the phone and by electromagnetic activity." So switch that phone off mate, because it's cooking your sperm.
This guy's fucked

The research found that 47% of the men who carried their phones within 20 inches of their business had sperm that'd been hugely affected.
Gedis Grudzinskas, a fertility consultant at St George's Hospital, said: "Men need to think about their wellbeing and try to stop being addicted to their phones.
"If you wear a suit to work put the mobile in your chest pocket instead of close to your testes. It will reduce the risk of your sperm count dropping or dropping so much."
Bad news for those who only ever experience the novelty of a chest pocket at weddings.

The study analysed the sperm of 106 men over the course of a year. The findings were originally published in the medical journal Reproductive BioMedicine.
