Learn more about: Change to your penis size

After prostate cancer surgery, about 7 out of 10 men will have a slightly shorter penis. Usually the change in length is minor (1 to 2 centimeters ).

Why does penis size change after prostate cancer surgery?

The main reason comes down to the tissues inside your penis. A part of your urethra is removed. Tissues also tend to shrink after trauma of surgery.

Sometimes, the penis can shorten because of changes to the tissues inside the penis. If you go for long periods without having erections, this can cause some scarring of the tissues in your penis, which can also lead to shortening.

What can you do about a shorter penis?

Get that blood flowing. Try encouraging blood flow to your penis after surgery. This might improve erections over time and stop your penis from becoming smaller.

Try an erectile aid called a vacuum pump (or penis pump). It can be used on its own or with PDE-5 inhibitor tablets (like Viagra) — which can help encourage blood flow to the penis. This may stretch the tissue and help maintain your penis size.
