YO IS BORN – After 4 years of intense research and development, The YO Home Sperm Test Kit was set to become the first consumer product offered by Medical Electronic Systems. A team of more than 25 experts and industry partners assisted in the creation of YO. No other company sought to address sperm testing in the same manner as YO. Medical Electronic Systems took on the challenge of producing the first consumer sperm home test to harness the power of the smart device and video to read motile sperm concentration and capture and display live swimmers in action.

Following rigorous clinical validation and testing, large clinical trials were conducted at multiple laboratories across America and Internationally. 500+ men used YO in a controlled setting to gather findings for an application to the FDA and other global regulatory bodies. Medical Electronic Systems’ vast technological and software experience in testing semen helped ensure the success of the YO Home Sperm Test.

From Professionals:


While an at-home semen analysis is not a replacement for a full laboratory test, it is a first step to learn where you stand and work on lifestyle-based fertility improvements. Medical Electronic Systems believes that YO provides those interested in sperm quality and conception with the best possible tool to start the journey. An at-home solution also provides an immediate and proactive option to test male fertility at the beginning of the pregnancy journey instead of waiting 1 year for an infertility diagnosis. YO reports a screening of the most important semen analysis parameter = Motile Sperm Concentration (MSC), but other sperm characteristics are important for conception.
