Definition Return to top
Semen analysis is a test to measure the amount and quality of a man's semen and sperm. Semen is the thick, white, sperm-containing fluid released during ejaculation.

Sample collection may involve masturbation and collecting the sperm into a sterile container. It may also be collected during intercourse by using a special condom supplied by your health care provider.

Normal Results Return to top
A few of the common normal values are listed below.
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 Abnormal Results Mean Return to top
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.
