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.
The test is sometimes called a sperm count.
You will need to provide a semen sample. Your health care provider will explain how to collect a sample.
How is Test PerformedSample 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.
A laboratory specialist must look at the sample within 2 hours of the collection. The earlier the sample is analyzed, the more reliable the results. The laboratory specialist will look at the sample to determine the following details:
- Fluid coagulation (thickening into a solid) and liquefaction
- Fluid thickness, acidity, and sugar content
- Resistance to flow (viscosity)
- Sperm movement or motility
- Number and structure of the sperm
- Volume of semen
