Semen Collection After Vasectomy: Care Instructions

Skip to the navigation

Your Care Instructions

After your vasectomy, you need to be sure you are not making any sperm. You will have to give your doctor a semen sample to send to a lab. The lab will count the number of sperm and may check the semen for signs of an infection.

You must wait for at least 6 to 8 weeks after the vasectomy to give your doctor the sample. This is because you may still have sperm in your semen for several weeks. You should also have ejaculated at least 8 to 10 times since the surgery.

Use some type of birth control during sex until you no longer have sperm in your semen. Also, a vasectomy does not protect you from sexually transmitted infections.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Take the semen sample to the lab or clinic within 1 hour after you collect it.
  • Collect the semen sample in 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. 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.
    • If you don't want to masturbate, your doctor may give you a special condom to wear during sex to collect the semen.

When should you call for help?

Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if you have any problems.
