I had cancerous prostate removed nearly two decades ago by same urologist who has now agreed to TRT. Guess he felt guilty lol. His first comment was "I see you are still living so I must have done a good job on the surgery". The operation despite his supposed "nerve sparing" expertise totally killed erections for about a year, thankfully as nerves and blood circulation returned performance slowly improved so didnt have to go the prosthetic route. My dear wife rode through the worst with me, and we returned to our normal routine. About a year ago the HRT nurse changed her formulations and libido went through the roof. With some help from Cialis, have been keeping up but sometimes seems like it isn't effective. After seeing several doctors and taking number of lab tests, finally confirmed the the free T was fluctuating too low sometimes.I am not sure how the previous prostrate issues play into that, but all things sexual in context will improve as you have higher levels of THE sex hormone.
The only way the prostate issues play is the none of other doctors I visited would provide TRT for this cancer survivor.
