Cell Phones May Harm Male Fertility

by Dr. Robert O. Young / NOVEMBER 15, 2006

DrYoung A study of more than 350 men has found that those who use a cell phone for more than four hours a day have fewer sperm, and also poorer quality sperm.

The study's author suggested that radiation from mobile phones might harm sperm by damaging DNA, the cells that produce testosterone, or the tubes where sperm is produced.

But another expert has argued that the problem was likely not the cell phones themselves that were the cause, but rather the sedentary nature of the cell phone users.

Men who talked on the phone for more than four hours a day had the lowest average sperm counts (50 million per milliliter), and the least healthy sperm.

Those who talked between two and four hours a day averaged sperm counts of 69 million per milliliter, and had moderately healthy sperm. Those who did not use mobile phones at all had sperm counts of 86 million per milliliter, on average, and the healthiest sperm.
