It's not the anecdotal reports you are looking for, unless you think of every one of the 3,187 men in the study as an anecdote, but a study at MSK found that a lot of men who had no erectile function even a year after nerve-sparing surgery, saw improvements over the following years. "In patients experiencing erectile dysfunction at 12 mo, the probability of recovering EF at 24, 36, and 48 mo was 22%, 32%, and 40%" about
half the previously potent men had poor erectile function at 12 months.
/www.ncbi.nlm.nih.gov/pmc/articles/PMC4605865/Now, this was at MSK - certainly among the best urosurgeons in the world, and certainly the best penile rehab program in the world (headed by John Mulhall). The message is - there may be a chance to regain erectile function (as well as size) but only if you remain devoted to your penile rehab program.
