CHECK YOUR SWIMMERS™
Check your sperm swimmers easily and accurately using the YO Home Sperm Test (Test Kit purchase required). Turn your smartphone, PC or MAC into a testing platform to assess your motile sperm concentration (the number of moving sperm in your sample) in about 3 minutes (testing time). That's right, MOVING SPERM - These swimmers are the only ones that REALLY count! YO also captures a video of your sperm for you to see or send, with your results, to an expert for further analysis. Find out if you are in the "NORMAL" range, see your YO SCORE rating vs. other men and learn about what you and your partner can do to improve your fertility potential by following YO’s Path to Pregnancy for couples. YO can also help you Find an Expert in your area if you need one.
