A word of caution for men trying to have kids: your laptop may be impacting the quality of your sperm¹.

给那些想要小孩的男人提个醒：你的笔记本电脑也许正在影响你的精子质量。

In the first scientific study of its kind, researchers found Wi-Fi on laptops could be causing damage to your sperm’s DNA².

Researchers studied how exposure to Wi-Fi enabled laptops, or the microwave radiation, impacted sperm production. They found men exposed for only four hours experienced measurable DNA damage to their sperm and a reduction in movement, or motility, of the sperm.

"The word is cautionary," said Dr. Dale McClure, Urologist and male fertility specialist from the University of Washington at Seattle. "I don't think we should rush out（冲出，突然出现） and stop using laptops, but I think if you're using a laptop, maybe not keep it on your groin（腹股沟） ."

The study was presented by Argentine researchers here in Denver at the American Society for Reproductive Medicine conference.

We asked men and women using laptops at Stella's Coffee Haus on South Pearl Street how it might impact their laptop use.

"Would it stop me from using my computer? Probably not. Would it make me take it off my lap? Maybe," said Craig Rangel, who said he already has one child and is thinking about another.

"At this point in life, because I'm not considering kids, I don't think it would even enter my mind," said Kristina Stamatis, a high school teacher who is single.

"I don't know how else I'd function without (my laptop)," said Nat Ridder, who is also single and childless, "And right now ... sperm count doesn't count for a lot in my lifestyle."

"Our society has kind of pushed us to a point business-wise where you don't really have a choice. You kind of have to use your computer all the time," said Dale Greer, a wine dealer³ who said he and his wife are considering having children.

An earlier study on microwave radiation from cell phones led scientists to determine it can reduce sperm quality. So now they recommend not carrying your cell phone in your pocket.

Until more definitive⁴ research is done you might want to keep your laptop away from your groin as well.
