Because of my leukemia, the radiation/hormone treatment that I had to have for the prostate cancer just about shot my testosterone levels all to hell. I have talked to my oncologist about this and the result is that I can't take any testosterone supplements for one year after my last hormone dose so we can see what my PSA is at that time. My year ends in March and so far the PSA is holding at 0.01, so I am going to bring it up again at my April visit. Hooray for the Golden Years.
