What is semen analysis?

    Semen analysis, also known as a sperm count test, analyzes the health and viability of a man’s sperm. A semen analysis measures three major factors of sperm health:

    • The number of sperm
    • The shape of the sperm
    • The movement of the sperm


    Why is sperm analysis done?

    A semen analysis is used to determine whether a man might be infertile—unable to get a woman pregnant. The test may be used to help determine the cause of a couple’s inability to get pregnant and to help guide decisions about infertility treatment.

    Preparation for the test

    You will need to avoid sexual activity, including masturbation, for 2–5 days before the sample is collected. This will help make sure your sperm count is at its highest level.

    Are there any risks to the test?

    There is no known risk to a semen analysis.
