Semen analysis

Sperm

A semen analysis is a test to evaluate a man's fertility.

Male fertility test; Sperm count

A semen sample will be obtained. Semen is the thick, white, sperm-containing fluid excreted during ejaculation. The method of sample collection should be discussed with the health care provider.

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.

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

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

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.
