Definition:

A semen analysis is a test to evaluate the fertility of men.

How the Test is Performed

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 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 an ejaculation for 2 to 3 days before the test.

Children:

  • This test is usually not requested of children.
Adolescent:
  • This test is usually not requested of adolescents.

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.
