YO Sperm Tester

Trips to the fertility doctor are rarely pleasant. The YO Sperm Test lets you see how your swimmers are doing from the comfort of your own home. Using an app and a phone-eating "clip" with a mini-microscope built-in, it's able to analyze your samples in just a few minutes, giving you a view of your actual moving sperm and some funny banter before displaying the results. It was developed by a commercial-grade producer of semen analyzers, has been found to be 97 percent accurate, and since it attaches to the same device you'll likely be using for "viewing material" anyway, it's far and away the most convenient way to check up on your reproductive health.
