Laptop Wi-Fi could slow down a man's swimmers, study finds

A new report from Argentinian scientists states that electromagnetic radiation in a laptop's Wi-Fi connection could take the swagger out of sperm.

The thought-provoking article, published in the journal Fertility and Sterility, is the culmination of a study conducted by Conrado Avendano, a biochemist working for the Nascentis Center of Reproductive Medicine in Cordoba, Argentina, in conjunction with a group of medical professionals.

The study found that semen from 29 donors placed for four hours in room-temperature petri dishes 3 centimeters from a laptop actively connected to Wi-Fi showed "a significant decrease in progressive sperm motility and an … Read more

High-tech 'fertility chip' measures sperm count, motility

If you'd like a better understanding of what it takes for sperm to be considered fertile, go grab your measuring spoons and look at the quarter teaspoon. Roughly that amount of ejaculate should boast anywhere between 20 million and 150 million sperm. Anything less than 20 million and fertility just might be an issue.

So Loes Segerink, a researcher at the University of Twente in the Netherlands, has developed a "fertility chip" that can accurately count one's sperm concentration as well as measure its mobility (when discussing sperm the synonym "motility" is often used). What's more, the test can be taken at home, with the ejaculate being, ahem, collected in a more private environment.

While simple home tests are already commercially available, the concentration readings are, well, simple, and indicate only whether sperm concentration is above or below that 20 million mark. But one man's sperm concentration of 19 million is certainly more fertile than another man's count of 1 million.

Segerink, who will be defending her doctoral dissertation in November, says the sperm flows past a liquid-filled channel on the chip beneath electrode "bridges." When cells pass beneath these bridges, a brief fluctuation in electrical resistance occurs. By counting these events, the chip is counting sperm.… Read more

The 404 906: Where Qwikster delivers the booty (podcast)

Happy birthday to the emoticon, invented 29 years ago today on a computer-science bulletin board at Carnegie Mellon University. Thanks for making parents around the world feel tech-savvy. :)

Before we get into the important Netflix news of of the day, Jeff tells us about his weekend experience at "Sleep No More," an interactive theater experience in New York that's loosely based on the Macbeth story--with a creepy twist. The plot plays out in various acts throughout a three-story abandoned warehouse in Chelsea, so tune in to hear more spoiler-free details and reserve your tickets here!

Next we'll get into the Netflix mea culpa delivered by e-mail and blog post this morning that's giving current Netflix subscribers even more reasons to moan about the recent price hike.

CEO Reed Hastings announced that the company will soon split in two, with the name of the DVD mail rental service changing to Qwikster (not to be confused with Quixtar, QuickStar, Kwikster, Quickster, or Quik-Star), while the video-streaming arm will retain the Netflix name and Web address.

We'll also talk today about a satellite plunging from space, a group of scientists that are poaching PS3 gamers to help find a cure for AIDS, and the last single-space parking meter disappearing in Manhattan today.

Report: Cell phone use could reduce sperm count

Gentlemen, your cell phone could be your closest enemy. According to an Italian report published in the Journal of Andrology (PDF), researchers in the United States and around the world have found that the radio-frequency electromagnetic radiation (RF-EMR) emitted by cell phones may decrease sperm count and damage sperm quality.

Though still inconclusive, the research focuses on several studies on both human and animal sperm. For humans, some of the studies exposed sperm from healthy nonsmoker volunteers to RF-EMR in a laboratory setting, while others compared the sperm health of subjects who regularly carried their cell phone in their front pants pocket with those who did not.

On the whole, sperm that were exposed to RF-EMR showed decreased sperm concentration; motility (the ability of a sperm to move toward an egg); morphology (the size and shape of sperm); and viability. Similarly, subjects who carried their phone in their pockets had a lower sperm concentration.

In one animal study, researchers put rats in special Plexiglas cages with cell phones just 0.2 inch underneath the cage bottom. After the rats were exposed to cell phone emissions for 6 hours per day for more than four months, the researchers found a 25 percent drop in the rats' percentage of live sperm. Their sperm also had the tendency to stick together, reducing the chance of fertilizing an egg.

Dr. Joel Moskowitz, the director of the Center for Family and Community Health in the School of Public Health at the University of California at Berkeley, told CNET that this is a complex matter that needs to be further researched.

For example, it's currently unclear what type of cell phones or phone service, such as GSM or CDMA, would cause a more adverse impact. "If more research is done, and we have more solid results, consumers could be presented with a choice," he said. "There might be phones or cell services that have less impact on our reproductive organs than others." … Read more

Stem cells used to create sperm in infertile mice

Welcome to mating 2.0: the sexual act itself might not change, but when the parts don't work, we'll simply build new ones.

So say scientists in Japan who, using stem-cell techniques, are the first to engineer sperm in infertile male mice that successfully fertilized eggs and produced offspring.

The team, led by Mitinori Saitou at Kyoto University, report in the journal Cell that it used stem cells to create primordial germ cells, the precursor to sperm cells, and injected those germ cells into the testicles of infertile mice. The cells eventually produced normal-looking sperm, which went on … Read more

Scientists to fight malaria via spermless mosquitoes

Female mosquitoes just don't get to have any fun. They mate only once, lay eggs, and eventually die.

In an effort to combat malaria, researchers at Imperial College London hope to take advantage of the female mosquito's plight--and reduce the mosquito population--by engineering spermless males. They say the key is that the females don't seem able to tell the difference; they still mate with the sterile males and proceed to lay eggs that never hatch.

This is an improvement over previous attempts to engineer sterile males, the team said, because that process often exposed the males to … Read more

The 404 438: Where Natali drinks her body weight in beer

All the 404 listeners out there will be very happy to see our own Natali Del Conte in the hot seat today. Our favorite guest just returned from a trip to the U.K. and, of course, Wilson is indulging himself in a bottle of Beck's Beer, so we foolishly decide to guess Ms. Del Conte's actual body weight. This sounds like a recipe for disaster, but I'm not one to let things spoil, so you'll have to watch the video below to witness me, Jeff, and Wilson making idiots of ourselves.

And of course, since Natali is here, we have to make things as uncomfortable for her as possible, so the first story of the day is about an LA sperm bank offering celebrity lookalike donors to their exclusive clientele. Each donor goes through an extensive scanning process to determine the celebrity they resemble the most, and the clients certainly love it: the service has been available for only a week and their Web traffic is already up 50 percent! We grill Natali for a second about which celebrity she would choose, but now that she's gone big time, she manages to weasel her way out of it.

After a few more stories that let Natali shake off her BOL-shackles, Jeff poses an interesting question to the group, by way of Reddit.com: When we get to be the age of our parents, will our generation be just as technologically inept, or will we retain our tech-savvy? This conversation actually stemmed from a rather painful iTunes tutorial that I overheard Jeff giving to Big Lou, and it's the perfect diving board for our show. All of us have varying opinions, but the general consensus is that because we've actually grown up with technology and computers (unlike our parents who were forced to adopt it later in life), we'll always have those building blocks to help us navigate through newer technologies, whatever they may be. Or we might just be bitter old luddites pecking away on our Jitterbugs, bemoaning a time when 140 characters ruled the world.
