Semen Analysis

(continued)

How To Prepare

You may be asked to avoid any sexual activity that results in ejaculation for 2 to 5 days before a semen analysis. This helps ensure that your sperm count will be at its highest, and it improves the reliability of the test. If possible, do not avoid sexual activity for more than 1 to 2 weeks before this test, because a long period of sexual inactivity can result in less active sperm.

You may be asked to avoid drinking alcohol for a few days before the test.

Be sure to tell your doctor about any medicines or herbal supplements you are taking.

How It Is Done

You will need to produce a semen sample, usually by ejaculating into a clean sample cup. You can do this in a private room or in a bathroom at your doctor's office or clinic. If you live close to your doctor's office or clinic, you may be able to collect the semen sample at home and then transport it to the office or clinic for testing.

  • The most common way to collect semen is by masturbation, directing the semen into a clean sample cup. Do not use a lubricant.
  • You can collect a semen sample during sex by withdrawing your penis from your partner just before ejaculating (coitus interruptus). You then ejaculate into a clean sample cup. This method can be used after a vasectomy to test for the presence of sperm, but other methods will likely be recommended if you are testing for infertility.
  • You can also collect a semen sample during sex by using a condom. If you use a regular condom, you will need to wash it thoroughly before using it to remove any powder or lubricant on it that might kill sperm. You may also be given a special condom that does not contain any substance that kills sperm (spermicide). After you have ejaculated, carefully remove the condom from your penis. Tie a knot in the open end of the condom and place it in a container that can be sealed in case the condom leaks or breaks.
