YO in the MAKING

Check out some cool facts about how YO was developed in this 30-second video!


The YO HOME SPERM test (AKA: YO) was 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 know how with smartphone technology to produce YO, the first smartphone-based, FDA-cleared home sperm test that tests motile sperm concentration (the number of moving sperm).  YO also lets users view and store a live video of their 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 ensures a reliable and dependable test result. Two tests per kit provide a cost-effective opportunity to re-test motile sperm count and confirm results.

The YO app is downloadable for free and guides users through the entire testing process with interactive step by step instructions reinforced with animations. Humor and fun facts about sperm are presented in the YO SPERM TRIVIA CHALLENGE and a secure archive stores YO test results for future viewing.
