    Sperm are male reproductive cells present in the ejaculate. A doctor can tell someone their sperm count using a test called semen analysis. The average sperm count is between 40 million and million sperm per milliliter. This number can vary between testing centers, with the above range coming from Resolve , a nonprofit fertility association. A doctor may recommend a semen analysis for many reasons, such as to test for possible underlying causes of infertility , how well the reproductive organs are working, or whether a surgical procedure for sterility was successful.

Semen analysis was standardized, inter-laboratory differences in assessment of sperm concentration were evaluated, and morphology assessment centralized. Lowest sperm concentrations and total counts were detected for Danish men, followed by French and Scottish men. Finnish men had the highest sperm counts.
