NEW YORK (Reuters Health) - Spending hours on a cell phone each day may affect the quality of a man's sperm, preliminary research suggests.That's right; no cause-and-effect relationship is proved. There could be a number of other reasons for the correlation between high cell phone usage and bad sperm.
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.
The concern is that, over time, the electromagnetic energy emitted from mobile phones could theoretically harm body tissue -- by damaging DNA, for example.
However, the new findings do not prove that cell phones somehow damage sperm, according to the researchers.
"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 Health.
It could be that men who have high sperm counts don't tend to work jobs where cell phones are required. It could be that men who use their cell phones a lot are more prone to wearing tight bun-huggers. It could be that men who use cell phones a lot are more likely to masturbate ten times a day.
Or, it could be that men with high sperm counts tend to talk less.
Note that there is no related study which has found lower quality eggs in women with high cell phone usage. In fact, I'll bet the more women use their cell phones, the higher quality their eggs.
UPDATE: Another new study has found that the more time a man spends on his computer, the more likely he is to write dumb posts on blogs.
