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.
Male fertility test; Sperm count
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:
Do not have any sexual activity that causes ejaculation for 2 - 3 days before the test.
If you are uncomfortable about how the sample is to be taken, discuss it with your health care provider.

The acidity of the semen and the presence of white blood cells (suggesting infection) may influence fertility. Testing may reveal abnormal shapes or abnormal movements of the sperm.
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.
Many of these abnormalities are reversible or treatable.
There are no risks.
