Information for the public
There are many causes of erectile dysfunction (the inability to get and maintain an erection). One cause is a build-up of fatty deposits in an artery in the pelvis. This narrows or blocks the artery, which reduces the flow of blood to the penis.
NICE has looked at using angioplasty and stenting of the affected artery as a treatment option.
NHS Choices may be a good place to find out more.
