(NewsTarget) Prolonged cell phone use may damage sperm in male users, suggests a study by researchers at the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University, Ohio.
The findings -- presented at the American Society of Reproductive Medicine conference in New Orleans -- were based on a study of 361 men attending the clinic for infertility tests. The men were divided into four groups -- one group with no cell phone usage; one group that used cell phones less than two hours a day; a group that used one for two to four hours a day; and a group with more than four hours a day of cell phone usage. The men who used their cell phones in excess of four hours showed a 30 percent drop in sperm motility and viability when compared to the men who did not use cell phones. Sperm count, quality, and shape were also reduced with each level of increased phone usage.
