  Mobile phone use damages sperm numbers and quality

  Mobile phone use does have an impact on male fertility.
  Or at least it does if you use your phone for four or more hours a day. Which seems like a lot for a grown-up.
  
  The American Society for Reproductive Medicine (ASRM) looked at 364 men. It found both numbers of sperm and quality fell for those using mobile phones.
  
  Those who did not use a mobile at all had average sperm counts of 86 million per millilitre, with 68 per cent motility and 40 per cent normal forms. But men using a mobile for more than four hours a day had average sperm counts of 66 million sperm per milliliter, 48 per cent motility and just 21 per cent normal forms.
  
  Researchers speculated that it could be electromagnetic radiation from mobiles.
  
  But other researchers suggested the difference could be down to other factors such as obesity, stress, or diet. If you're on your phone for four hours a day you're probably not doing enough excercise. Or heavy phone users could be under more pressure and stress at work.
  
  However, it's not all doom and gloom from the ASRM. It's also discovered that sperm from heavy smokers, which has less ability to bind with an egg, can be fixed by washing it in a "low-concentration cannabinoid solution".
  
  More on both pieces of research here.

  Cell Phone Use Associated with Decline in Fertility
  
  In an observational study, researchers from Cleveland, Mumbai, and New Orleans found that the number of hours in a day that a man uses his cell phone can affect all aspects of his sperm profile.
  
  Three hundred and sixty-four men undergoing evaluation for infertility were classified into three groups according to their sperm count. Among the men in the group with a normal sperm count, those who did not use a cell phone at all had sperm counts averaging 86 million per milliliter, with 68% motility, and 40% normal forms. Among men in the normal count group who used a cell phone more than four hours a day, the averages were significantly lower: 66 million sperm per milliliter, 48% motility, and 21% normal forms.
  
  The effect of cell phones on sperm parameters may be due to the electromagnetic radiation the devices emit or to the heat they generate. The researchers note that further studies will be necessary to identify the mechanism involved in the reduction of sperm quality due to cell phones.
