From what I understand, yes, that is true. When you go on TRT your testicles stop production. My MO told me once I got on TRT it would be for life. I would assume there is a cancer scenario down the road when my MO would stop the TRT.

Some guys like to know every future step and contingency. I don't. I am trying to live my life for now. I leave the future treatments up to my MO and I'll deal with it when it comes. I just follow instructions. He knows my risk tolerance, that I want to live as long as possible etc, etc. Right now, thankfully, I am feeling no SE from my cancer or any treatments (other than having a penile implant due to surgical/ ADT induced ED-BUT, wow I love the implant so far!).
