can i get an erection after prostate cancer treatment

to help you understand why prostate cancer treatment may cause you to have erectile dysfunction, it is good for you to learn how your body may be changed by your treatment

Usually when a man is sexually aroused (excited):

The brain sends a message telling the blood vessels in the penis to get wider.
This causes more blood flows to the penis.
When this happens, the penis gets bigger and hardens. This causes an erection (when your penis is hard enough to have sex). Some prostate cancer treatments may affect the nerves, muscles, or blood vessels that let you have an erection. Other prostate cancer treatments may affect your libido (or sex drive).
