I had 44 radiation treatments and 4 months of Lupron at age 83. Th e Lupron almost killed me and think it would have if I had not stopped at 4 months. The pain in my muscles, head, and bones was awful 24 hours per day. The sweats were bad also but not life threatening. My recovered testosterone was 111 and falling. It has been a year since my treatments, and I am now on testosterone replacement therapy which has stopped the serious side effects. After 2 weeks on testosterone, I am seeing some libido recovery. I have also read new research articles that state that low testosterone has no benefit and can harm the cardiovascular, muscle, and bone systems.
