We’re living in a digital age, gentlemen. Everything’s wired, with free WIFI in many places. And cell phones, tablets and laptops that grow in power each year.

That’s not a bad thing. After all, it shrinks the world and brings us closer together. You can download the latest from Justin Bieber, go Skyping with Uncle Bob. The future is wireless. And it’s getting bigger.

But if your swimmers have any say in the matter, you might avoid the wireless gig. Because according to this article, the high-powered radio signals emitted from wireless devices – and laptops in particular – may damage the genetic code programmed in your sperm.

Hold on now. The researchers aren’t suggesting you take a sledge hammer to your MacBook. What they’re saying is that radio signals are absorbed by the body, and they’re looking into it.

The study, published in the journal Fertility and Sterility, consisted of semen samples from 29 healthy donors. The researchers separated each donor sample into two pots. The first pot was kept by a laptop with a wireless internet signal. The second was kept under similar conditions but without the laptop.

After four hours, the sperm near the laptop were significantly damaged, with poor mobility and changes to the genetic code they carried. And while it’s possible that there were other factors that may have damaged the sperm – which are vulnerable to heat and other factors once outside the body – the results suggest there’s enough here to warrant further investigation.

This isn’t the first study to illustrate the link between radio signals and damaged sperm. In August, a study published in the Journal of Andrology suggested the radiation from cell phones had a similar effect. Bear in mind that laptops emit radiation at higher levels that your mobile.

This ain’t the end of the world. The results, while thought-provoking, are open to scrutiny. At this time, they’re inconclusive.

But you can’t go wrong with a little common sense, at least until we know more about how radiation affects sperm and the code that it carries. Keep your cell phone out of your pocket. And your laptop off your laptop.
