Learn more about: Change to your penis size

Why does a change in penis size after prostate cancer surgery happen?

The main reason comes down to the tissues inside your penis.
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 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. (Find more on erectile aids in Second Base.)

Hear from a guy who’s been there:
"My partner kept reassuring me that it doesn’t matter, but it did to me. I did try the pump. My penis felt cold and strange but it did help." – Gary, 69 years

As always, if you’ve got questions about a change in your penis size and ways to improve, talk to your doctor or care team for assistance.
