@ken1969 The purpose of ADT is to reduce testosterone to castrate levels defined as below 50. In the old days this was done by surgery and was permanent. With the shots it is to make castration reversable. Your prescription was for 4 months, and your doctors expected you to regain testosterone within 6-8 months. It has already been twice as long, and you are still at castrate levels. Permanently losing the ability to produce enough testosterone to eliminate the negative effects of ADT is a known side effect with the probability getting higher with age. If you want the doctors to listen to you do not mention that testosterone does not feed cancer. Mention that you have already had twice as much ADT as prescribed and the side effects are ruining your life.

With radiation the cancer cells take 1-2 years to die off. The only way to check if the radiation treatment worked is to recover testosterone to a level that eliminates the side effects (300-400) and see if PSA remains low (<.5). It does not look like that will happen for you without TRT. If PSA increases TRT can always be stopped.
