The YO Team has been working hard behind the scenes for 4 years to create this product! We are SO excited to officially launch today! Check out the site and order YO Home Sperm Test at: www.yospermtest.com


The YO HOME SPERM test (AKA: YO) is developed by the same team at Medical Electronic Systems that produces the automated line of Sperm Quality Analyzers (SQA’s) used in hospital labs, universities and IVF centers globally. With over 20 years of expertise developing automated sperm analyzers, MES successfully faced the challenge of merging company knowhow with Smartphone technology to produce YO, the first Smartphone based, FDA cleared home sperm test that allows you to test motile sperm concentration (the number of moving sperm) on your phone, view and store a live video of your sperm and receive an automatic test result in under 3 minutes.

YO was four years in development and extensively tested. YO’s consistent performance of >97% accuracy insures a reliable and dependable test result. Two tests per kit provides you with a cost-effective opportunity to re-test your motile sperm count a second time to confirm your results.
