Gentlemen, your cell phone could be your closest enemy. According to an Italian report published in the Journal of Andrology (PDF), researchers in the United States and around the world have found that the radio-frequency electromagnetic radiation (RF-EMR) emitted by cell phones may decrease sperm count and damage sperm quality.
Though still inconclusive, the research focuses on several studies on both human and animal sperm. For humans, some of the studies exposed sperm from healthy nonsmoker volunteers to RF-EMR in a laboratory setting, while others compared the sperm health of subjects who regularly carried their cell phone in their front pants pocket with those who did not.
On the whole, sperm that were exposed to RF-EMR showed decreased sperm concentration; motility (the ability of a sperm to move toward an egg); morphology (the size and shape of sperm); and viability. Similarly, subjects who carried their phone in their pockets had a lower sperm concentration.
In one animal study, researchers put rats in special Plexiglas cages with cell phones just 0.2 inch underneath the cage bottom. After the rats were exposed to cell phone emissions for 6 hours per day for more than four months, the researchers found a 25 percent drop in the rats' percentage of live sperm. Their sperm also had the tendency to stick together, reducing the chance of fertilizing an egg.
Dr. Joel Moskowitz, the director of the Center for Family and Community Health in the School of Public Health at the University of California at Berkeley, told CNET that this is a complex matter that needs to be further researched.
For example, it's currently unclear what type of cell phones or phone service, such as GSM or CDMA, would cause a more adverse impact. "If more research is done, and we have more solid results, consumers could be presented with a choice," he said. "There might be phones or cell services that have less impact on our reproductive organs than others." … Read more
