A semen analysis measures the amount of semen a man produces and determines the number and quality of sperm in the semen sample. A semen analysis is usually one of the first tests done to help determine whether a man has infertility problems. Problems with the semen or sperm affects more than one-third of infertile couples.
Tests that may be done during a semen analysis include:
A semen analysis is done to determine whether:
You will be asked to avoid any sexual activity that results in ejaculation for 2 to 4 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. It is also best to avoid drinking alcohol for a few days before the test.
It takes about 10 – 12 weeks from the initiation of new sperm formation for fully mature sperm to appear in the ejaculate. During this period sperm are very easily adversely affected by conditions such as stress, fever, hard work and minor health disturbances.
Your doctor must therefore consider any significant events in your history as far back as three months before the semen analysis.
Most experts recommend that men undergoing infertility evaluation have three separate analyses performed with at least 4 weeks in between analyses.
If a meaningful problem persists your doctor will probably refer you to an “urologist” or an infertility clinic for further evaluation and treatment.
