About the App: Check your sperm swimmers using the YO Home Sperm Test (Test Kit purchase required), a new, innovative app that turns your smartphone into a testing device for assessing motile sperm concentration (the number of moving sperm). That's right, the word here is MOVING - These guys are the only ones that REALLY count!! Aren't you curious to see an actual video of your sperm, find out if you are in the "NORMAL" range AND see your YO SCORE?

The YO Home Sperm Test is FDA cleared as an over-the-counter medical device and has been thoroughly tested for precision, accuracy and much more by all of us at Medical Electronic Systems. We've been in the automated sperm testing business for more than 20 years so we know what we're doing.

To run a test on the YO Home Sperm Test, download this app and purchase the affordable, two test YO kit on our website (www.YOspermTEST.com). The kit includes ALL of the supplies you'll need to run both tests plus a YO Clip (mini microscope) that fits over your phone. For more details about how YO works, read on…

The YO Home Sperm Test app operates together with the YO Clip, your phone’s built-in camera and light to assess, report and display a video of the MOTILE SPERM CONCENTRATION (MSC) in your (or any other male human's) semen sample. Results are reported as either LOW MSC RANGE: Less than 6 Million (sperm) per milliliter or MODERATE/NORMAL MSC RANGE: Greater than or equal to 6 Million (sperm) per milliliter. The YO Home Sperm Test app guides you through the testing process step by step on your Smartphone’s screen providing both written and animated instructions. Your test results and videos are stored securely in the YO archive until you delete them.

The YO Home Sperm Test provides information about your test results, explaining what MSC means and what a result of LOW or MODERATE/NORMAL means. The cutoff of 6 million sperm per milliliter has been established based on the World Health Organization's published guidelines (WHO 5th ed. reference values for sperm motility and concentration) and statistical modeling and expert publications.

Only missing one thing....

Export capabilities of the video, to share with a partner. Maybe in future update?
Other than that it works as advertised.

Aj yeeeeeeeee ,

Doesn’t work I think

Everyone that I know tried this and we all got the same results 6 mil per milliliter I don’t think it’s accurate at all

Worked well

I'll admit it felt weird but it worked and was much cheaper than going to the doctor and having a lab do it.
