Is Laptop Wi-Fi Murdering Your Semen?

According to a new study by Argentinian scientists, published in the bluntly named journal Fertility and Sterility, the electromagnetic radiation generated during wireless web-surfing might be completely bulldozing your mojo.

Here’s an excerpt from the (actually pretty awkward) Reuters Health report:

The digital age has left men’s nether parts in a squeeze, if you believe the latest science on semen, laptops and wireless connections. In a report…scientists describe how they got semen samples from 29 healthy men, placed a few drops under a laptop connected to the Internet via Wi-Fi and then hit download.

Four hours later, the semen was, eh, well-done.

A quarter of the sperm were no longer swimming around, for instance, compared to just 14 percent from semen samples stored at the same temperature away from the computer. And nine percent of the sperm showed DNA damage, three-fold more than the comparison samples…”Our data suggest that the use of a laptop computer wirelessly connected to the internet and positioned near the male reproductive organs may decrease human sperm quality,” [Dr. Conrado Avendaño of Nascentis Medicina Reproductiva and his colleagues] write in their report. “At present we do not know whether this effect is induced by all laptop computers connected by Wi-Fi to the internet or what use conditions heighten this effect.”

A separate test with a laptop that was on, but not wirelessly connected, found negligible EM radiation from the machine alone.

The study makes it clear early on that none of this—even when taken together with past scientific reports—is conclusive; these cases of MacBook-cooked spermatozoa shouldn’t lead avid tech-users to prematurely freak out as if we were talking about cell phones and brain tumors. And although male infertility has been linked to things as diverse as hormone imbalance, some types of medicine, heavy smoking, and conditions that cause abnormally high temparature of the testicles, leading experts in the field are hesitant to embrace the “wireless Internet is frying your junk” narrative.

“This is not real-life biology, this is a completely artificial setting,” Dr. Robert Oates, president of the Society for Male Reproduction and Urology, told Reuters. “It is scientifically interesting, but to me it doesn’t have any human biological relevance…[A]ll of this angst is created for real-life actual persons that doesn’t have to be.”

Moreover, there has yet to be a comprehensive study that examines whether laptop use—wireless or Ethernet—has any effect whatsoever on fertility or pregnancy. So rest assured: there’s still a good chance watching season four of Parks and Recreation on Hulu with your Dell resting on your lap won’t make you sterile.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
