You commented - I had bilateral nerve sparing and am at 7 months post RP and my erections are slowly coming back (were a 10/10 pre-RP and at 7 months I'm at about a 5-6/10 erection and Urologist says I will eventually recover to a 9/10 (I'm only 54 years old.) BUT, if I do salvage radiation, that will be the nail in the coffin as far as achieving erections due to the blood vessel damage from the radiation, so no erections without a pump, injections or high-dose Viagra/Cialis (which may not be enough.)

I had SRT in March 2016 after BCR. I too had nerve sparing surgery. My radiologist counseled me about the possibility of the radiation treatment causing ED. In my case, study of one, did not. Why not, who knows, study of one though. I do believe the improvement in the planning software and delivery of the radiation over the years may be a factor.
