Alternate Names : Male fertility test, Sperm count
A few of the common normal values are listed below.
- The normal volume varies from 1.5 to 5.0 milliliter per ejaculation.
- The sperm count varies from 20 to 150 million sperm per milliliter.
- At least 60% of the sperm should have a normal shape and show normal forward movement (motility).
However, how to interpret these values and other results from a semen analysis is not completely certain.
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What do Abnormal Results Mean?
Abnormal results may suggest a male infertility problem. For example, if the sperm count is very low or very high, there is a likelihood of being less fertile. The acidity of the semen and the presence of white blood cells (suggesting infection) may influence fertility.
However, there are many unknowns in male infertility. The results from the test may fail to explain the cause. If a low sperm count or abnormal semen is found, further testing may be required.
