Fertility experts from Technion - Israel Institute of Technology in Haifa are sounding the alarm on cellphones and a decrease in male fertility. Over a year's time, a fertility clinic at the university tracked the sperm quality and cellphone use of 106 men.
It found that men talking on a cellphone for more than one hour a day, or while the phone was charging, had nearly double the risk of low sperm count. In fact, it found that talking on the phone while it was charging is one of the two biggest risk factors for male infertility, along with smoking.
The study also found that 47% of the men who regularly kept their phones less than 20 inches from their groin, say in a pants pocket, had lower sperm count. However, the researchers weren't able to confirm if there was a definite link or some other factor.
Overall, the researchers aren't entirely sure what is causing the lowered sperm count, although they suspect either the heat of the phones or heat generated from the electromagnetic signals are to blame. They recommended a large-scale study to get more information.
In the meantime, many fertility experts are cautioning men to use cellphones sparingly, keep them somewhere other than a pants pocket when on the go, and put them in a different room at night while they're charging.
This isn't the first time cellphones have been linked to serious health problems. Read about a recent study that linked cellphones with cancer, and why it might not be the crisis it appears.
