Smartphone microscope and app for testing your sperm

YO is an FDA-cleared sperm quality analyzer for your smartphone. It consists of a detachable mini microscope and light that clips to your mobile phone. You "acquire" a sperm sample, drop it into the YO Clip, and the app records a video of your sperm in action and analyzes the activity. Available in January, you can pre-order two tests for $50. I bet the app has social media integration so if you have strong swimmers, you can proudly share the proof with your friends.

"Extensive testing has been performed on the YO Home Sperm Test-over four years to be exact," Marcia Deutsch, CEO of Medical Electronic Systems, the parent company of YO Sperm Test and producer of commercial-grade semen analyzers for major labs, tells Fit Pregnancy. "The technology is able to read the sperm sample 99 percent of the time, as long as the instructions are followed. [If it can read the test] the results are more than 97 percent accurate based on FDA studies of 316 participants."

Because it's an over-the-counter product, Deutsch says the test can't reveal actual values, but rather gives a reading of "low" or "moderate/normal" based on World Health Organization (WHO) guidelines for sperm motility (how well they move) and concentration (how many there are). The test reports a composite of these two parameters called "motile sperm concentration," or the number of moving sperm.
