Spending hours on a cell phone each day may affect the quality of a man's sperm, preliminary research suggests.
In a study of 361 men seen at their infertility clinic, researchers at the Cleveland Clinic found an association between the patients' cell phone use and their sperm quality.
On average, the more hours the men spent on their cell phones each day, the lower their sperm count and the greater their percentage of abnormal sperm.
The findings, published in the journal Fertility and Sterility, add to questions about the potential health effects of cell phones and other wireless devices. Some studies, for example, have linked long-term cell phone use to a higher risk of brain tumors, though many other studies have found no such connection.
