Men may want to be sure their unlimited minutes include calls to the urologist, USA Today reports, because a new study shows a possible link between cellphone use and male infertility. Researchers split 361 men under 40 into groups divided by amount of daily cell use and found the 4-plus-hours users had lower sperm counts and proportionally more malformed sperm.
The results are “quite preliminary,” a study co-author cautions, adding, "There are hundreds of variables that can affect our conclusions." The location of the phone, for example, could be a much more important factor than connection time. Says another researcher, "To get an effect, I think you've got to have the phone very close to the sperm."
