A new report by Argentine researchers claims that Wi-Fi technology can damage sperm cells.

A team at the Nascentis Center for Reproductive Medicine in Cordoba, Argentina conducted the study, in which scientists took the sperm from 29 healthy men and exposed them to a Wi-Fi connected computer for four hours.

According to the report published in the medical journal, “Fertility and Sterility,” as a result of being exposed to the signal, the sperm “showed a significant decrease in progressive sperm motility and an increase in sperm DNA fragmentation.”

Some disagree with the scientists’ assertion and say this sounds a false alarm. Dr. Robert Oates, president of the Society for Male Reproduction and urology says the study is “artificial.”

“This is not real-life biology; this is a completely artificial setting,” he told Reuters. “It is scientifically interesting, but to me it doesn’t have any human biological relevance.”

“Suddenly all of this angst is created for real-life actual persons that doesn’t have to be,” he added.

The group claimed the experiment may have been the first true test of wi-fi’s effect on sperm and requires more research to make a definitive conclusion.

“To our knowledge, this is the first study to evaluate the direct impact of laptop use on human spermatozoa. Ex vivo exposure of human spermatozoa to a wireless internet-connected laptop decreased motility and induced DNA fragmentation by a nonthermal effect. We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility,” the report stated. “Further in vitro and in vivo studies are needed to prove this contention.”
