Extended "ADT" killed 1 testicle and severely injured the other (also screwed up my lungs, among other things). Started with T of 750, dropped to 125. Surgery & radiation shrunk my asset. Pills did nothing - total ED and no libido. Still use the pump once a week for blood flow and to avoid Peyronie's. I would have to use the pump and 2 small rings to give myself a shot.
Not happening.
At this point I am "here, now" (accepting my limitations), and as the Buddha advises I appreciate what I have and choose not attach to what I do not have. My young wife of 32 years has lost interest and her girl parts no longer work. Like Jane Fonda she has 'closed up shop down there', so she says she would have to do something extraordinary if I recovered my interest in such things.
After all I have gone through to try and get rid of my cancer, no way would I up my testosterone and maybe encourage any stray cancer cells that remain. Those blood test zeros give me much more satisfaction than sex ever could. There is indeed life beyond sex, and it is pretty good, actually.
EDIT: insurance paid for the pump - $500 - as it is a "durable medical device". Still works fine 12 years later.
