Removing the testicles (orchidectomy)

Find out about surgery to remove the testicles to treat prostate cancer.

Prostate cancer needs testosterone to grow. Testosterone is the male sex hormone produced by the testicles.  

Removing the testicles helps control the growth of advanced prostate cancer. This is an orchidectomy, also called orchiectomy. After removal of the testicles, the level of testosterone in the blood falls quickly.  

Removing the testicles is not a common treatment. Hormone treatments are the main treatment to reduce the level of testosterone in your blood.  

Some men prefer to have this surgery as it is one treatment compared to regular injections. Orchidectomy is not reversible. You may find the removal of your testicles upsetting.

What happens

Removing the testicles is a simple operation. You have the operation as an inpatient in the hospital. Most men stay overnight, but you might be able to go home on the same day.

Before the procedure

You have an orchidectomy under general anaesthetic. You will be asleep for the whole operation. Some men have a spinal anaesthetic. That means you are awake, but have an anaesthetic injection into your spine. You can’t feel anything below the level of the injection.

During the procedure

The surgeon makes a small cut in your scrotum (the sac which holds your testicles). After removing your testicles, your surgeon may put in fake testicles (prostheses) so that your scrotum looks and feels the same.  

You may be able to have a smaller operation to remove only the inner part of your testes. This is a subcapsular orchidectomy. You don’t need a prosthesis after this operation.

After the procedure

You may have some discomfort after the operation. You will have a few stitches on your scrotum. Usually, these are absorbable. So, they don’t need removal. You may go home the same day or stay in the hospital overnight.

Possible risks

Your doctors will make sure the benefits of having the surgery outweigh these possible risks:

  • hot flushes
  • erection problems

Follow up

You will have a follow up appointment 6 weeks or so after your surgery. At the appointment your doctor:

  • examines you
  • asks you about how you are and if you have had any problems  

It is also your chance to ask any questions. Write down any questions you have before your appointment to help you remember what you want to ask. Taking someone with you can help you to remember what the doctor says.

After your first check up you will continue to have follow up to monitor your cancer. How often you have checkups varies. Ask your doctor how often you need to have checkups and what they will involve.
