Men who spend hours each day talking on their cell phones may experience decreased sperm count, as well as a higher percentage of "abnormal" sperm, according to preliminary data from a new study.
Researchers evaluated 361 men being treated at the Cleveland Clinic's infertility clinic in Ohio, and found an association between cellular phone use and sperm quality, Reuters reported.
The findings, published in the journal Fertility and Sterility, indicate the more hours that men spent on their phones each day, the more damage to their sperm.
Researchers believe the electromagnetic energy emitted from cell phones could theoretically harm body tissue — by damaging DNA, for example.
They added, however, that the findings do not directly indicate that cell phones damage sperm.
"Our results show a strong association of cell phone use with decreased semen quality. However, they do not prove a cause-and-effect relationship," lead researcher Dr. Ashok Agarwal told Reuters.Click here to see the actual study
