Overview

A semen analysis is a test to measure the number and quality of your sperm. The lab will also measure the amount of liquid (semen) produced with the sperm. Sperm quality is determined by looking at the shape of the sperm, the number of sperm, and how well they move.

You may have a semen analysis to help find the cause of fertility problems. Or your doctor may do a semen analysis to find out if a vasectomy was successful. You may have to give a few samples over time.

You may need to have your semen checked again after several weeks to see if there are any changes.

How can you care for yourself at home?

• Do not have sex or masturbate for 2 to 5 days (but no longer than 1 week) before you collect the semen sample. This allows your sperm count to be at its highest. It also helps make sure the test is accurate.
• Collect the semen sample into the container your doctor gives you.
  • Wash and dry your hands and penis.
  • Ejaculate into the container. Do not use any lubricant or saliva. Do not use a regular condom to collect the semen, because the powder in it can kill sperm. Collect the entire amount of semen you produce.
  • Keep the semen close to body temperature. A good way to do this is by keeping the semen container in an inside pocket. Avoid getting the semen hot or cold.
  • Take the semen sample to the lab or clinic within 1 hour after you collect it.
