As explained above, the best way to find out your sperm count is by visiting a fertility specialist and undergoing a sperm test or seminogram.
However, there's a fertility test available in stores called SpermCheck, which allows you to find out in minutes if your sperm count is within the normal range. It works more or less like a pregnancy test—reading its results is easy, as you get either a positive or a negative result.
Anyway, we always recommend that you visit a doctor to get accurate results.
