Each kit comes with two (2) tests. Additional refill tests are also available for repeated usage so that you can see changes over time. Your sperm count can change daily, weekly, and monthly due to changes in your health, lifestyle, and the world around you. To get the most accurate benchmark results, we recommend testing twice to establish a baseline for measuring progress. After that, you should test at least monthly outside of your partner’s fertile window (the six-day interval when pregnancy can occur, ending on her ovulation day).
In many cases, men start to see results starting after one month. That said, be aware that it takes sperm a while to fully develop. It may take two months or longer to see meaningful concentration changes after implementing health and lifestyle changes.
