The sample may be obtained by masturbation into a sterile container. It may also be achieved by intercourse using a special condom supplied by the health care provider. The sample must be analyzed within 2 hours of the collection. The earlier the sample is analyzed the more reliable the results are.

How to prepare for the test:

There should be no sexual activity that causes ejaculation for 2 to 3 days before the test.

How the test will feel:

If the man is uncomfortable about how the sample is to be taken, this should be discussed with the health care provider.

Why the test is performed:

The test is performed if the patient's fertility is in question. It is helpful in determining if there is a problem in sperm production or quality of the sperm as a cause of infertility. The test may also be used after a vasectomy to make sure there are no sperm in the semen.
