Laptops with wi-fi technology have given us the capability to connect to the internet almost anywhere, but now researchers say wi-fi radiation may also be giving us more infertility by decreasing sperm motility and damaging DNA in sperm.

Published in the medical journal Fertility and Sterility, the study looked at how radiation emitted from wi-fi laptops impacts sperm health. Researchers in Argentina took semen samples from 29 healthy men, and they measured sperm motility after four hours of exposure to wi-fi radiation from a laptop wirelessly connected to the internet. Sperm in the control group was kept at the same temperature for the same amount of time, but was not exposed to wi-fi radiation.

Of the sperm exposed to the wi-fi radiation, 25 percent stopped swimming. Only 14 percent of unexposed sperm ceased to swim after four hours. Wi-fi sperm also showed 9 percent DNA fragmentation, or irreversible damage in the genetic code, while sperm in the control group only showed 3 percent.

Electromagnetic radiation is a product of wireless communication, and researchers suggest this radiation may be causing sperm damage. "We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility," say the researchers in their report. They also recommend more studies be done to examine the long-term impact of wi-fi radiation on sperm in a real world setting.

It's important to note researchers compared radiation emissions in wi-fi laptops to laptops without wi-fi connection. Emissions from laptops without wi-fi were negligible, while emissions from wi-fi laptops was significantly higher.

Previous studies on laptops and fertility have produced similar results. Another legitimate concern is scrotal hyperthermia (elevated testicle temperature), which can easily occur if you sit with a laptop in your lap for hours at a time. Scrotal hyperthermia negatively impacts sperm quality and can cause decreased fertility.

The solution? Keep the laptop off your lap. Laptops may have been designed for convenient lap placement, but this is obviously not best for your health. Instead, use your laptop on a desk or get a specially designed laptop tray.

Also, use a wired internet connection when possible, as it appears the radiation emitted from wi-fi communications may be particularly harmful to sperm.

New research conducted at Wageningen University in the Netherlands concludes that wi-fi signals might damage nearby trees, causing them to develop severe abnormalities in their bark and leaves.

In the Netherlands, about 70 percent of trees in urban areas already show such symptoms, although trees in the wild have no such symptoms. These deformities could not be attributed to viral, bacterial or fungal infections.

The study was paid for by the city of Alphen aan den Rijn which was trying to determine what was causing its trees to suffer deformities. The study exposed 20 ash trees to varying frequencies of electromagnetic radiation over a three-month test period. The trees located nearest the wi-fi radio, researchers found, showed a "metallic luster appearance . . . followed by desiccation and death of a portion of the leaf."

Government agency expresses doubt about study conclusions However, a statement from the Netherlands' Antenna Agency (the government department there that handles electromagnetic broadcast authority, much like the FCC in the United States) has issued a statement denying any conclusive link between Wi-Fi and tree health.

It should also be noted that this study involved only 20 trees, which is a small sample size, and so far the study results have not been repeated.

In fact, the tree health problems observed in the study could be due to something much simpler. For example, perhaps the trees closest to the wi-fi radio were also close to an air duct that was exhausting air contaminated with fungal spores. Until the study is repeated and expanded to a larger sample size, it's simply not conclusive. Many people are "sensitive" to wi-fi signals Personally, I understand very well that people may be sensitive to wi-fi signals. I'm sensitive to mobile phone signals and get a headache if I talk on a mobile for more than a few minutes (which I try to avoid doing, of course). I've also spoken with people who told me they experience similar headaches around wi-fi signals.

It seems entirely reasonable to be concerned about the health implications of wi-fi radios, especially given that there are now so many of them in urban environments. Hopefully, further study will be conducted on this topic so that we might all learn more.
