Hi @havhav
I'm no expert but can give you some insight ..

Diagnosed at 60 Gleason 4+3 but I think I was a little less advanced, there was no obvious tumor on the outside of the prostate, just inside with slight invasions but clean margins.

At about 3-6 mos I could get about 70%-80% maybe a little less, not enough for fun play with my wife and it would come with a dry orgasm. Using a little pharmaceuticals was helpful. There are a couple other options if needed but I'll let the docs get into that.

I think the doctors are kind of stuck giving you the answers like they do in percentages. Every question I asked was answered with XX% of men your age recovered blah blah after this amount of time. Virtually like he was reading off a chart. Unfortunately this is as close to "scientific facts" as I believe they can get.

It's my belief..
A. They don't really know exactly what they are up against till they get in there.
B. Everyone's a little different in presentation and healing capacity.

I really think that's the best they can do, nerves are funny things and take a LONG time to heal/grow
One of the things I found after diagnosis is that no one I knew talked about it much, after diagnosis I found several of the same acquaintances had dealt with this. Many get treated get better and move on with their lives, you tend not to hear from them. Meaning, I think you might hear more about bad outcomes than good ones.
Best of luck to you and your husband!
