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.
Alternative Names:
Male fertility test; Sperm count
How the test is performed:
You will need to provide a semen sample. Your health care provider will explain how to collect a sample. 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. 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
How to prepare for the test:
Do not have any sexual activity that causes ejaculation for 2 - 3 days before the test.
How the test will feel:
