Do you know if you're fertile? You may be able to use your phone to test that

Why it matters to you

Male infertility is a common affliction, but it often goes undiagnosed. A new device from Harvard could change that soon.

Your self-diagnosing powers are about to get a lot more … personal. In this new age of telemedicine, not only do we not need to leave our homes to see a doctor, but we may not even need to see a doctor at all in order to test fertility.

The bright minds at Harvard University created a new device that allows men to measure their ability to procreate with no more than their smartphone. The cost of production is a measly $4.45 and a prototype of the device requires less than five seconds to test how strong your swimmers are. It also analyzes sperm count with 98 percent accuracy.

“Although male infertility is as common as female infertility, it often goes undiagnosed because of socioeconomic factors such as stigma, high cost of testing, and availability of laboratory facilities,” the Harvard team noted in an abstract published in Science. “To facilitate the necessary testing, Kanakasabapathy et al. have designed a smartphone-based assay that can be performed at home or in a remote clinic without access to laboratory equipment.”

The easy-to-use device can be attached to your smartphone, and comes with a companion app — thanks to a microfluidic chip that comes with a minuscule tube, home testers can collect up to 35 microliters of semen, seal the sample, then use the device’s LEDs and lenses do the work. After analysis (which depends on stills and videos from your smartphone camera), you will get your results. “The accuracy of this approach was very similar to that of computer-assisted laboratory analysis, even when it was performed by untrained users with no clinical background, demonstrating its potential for use at home and in low-resource settings,” the team noted.

Unfortunately, the device isn’t very good at identifying deformed sperm, which is key in determining fertility. That said, researchers believe that they can make improvements to address this issue. As exciting as these developments are, the device is still very much in its nascent stages. For one, the at-home fertility tester doesn’t even have a name yet and has not been approved by the Food and Drug Administration. So while the future looks bright, it’s still a ways away when it comes to testing your sperm with your phone.
