Why are two tests included in the YO Home Sperm Test kit?

Your sperm values can change over time. A “low” result today could be “normal” in a month or visa-versa. It is important to run your test at least two times – especially if you receive a LOW MSC RANGE result the first time.  YO can also be used multiple times to monitor fertility improvement efforts over a longer period of time by purchasing re-test kits.
