Cleveland Clinic has been doing research to look at how cell phone use may affect fertility. The conclusion: high cell phone use in males may lead to decreased sperm count, as well as a higher percentage of "abnormal" 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.

Radiation emitted by handsets may be the cause of the damage.

"There was a significant decrease in the most important measures of sperm health with cell phone use and that should definitely be reflected in a decrease in fertility" added Agarwal.
