By the way, I pointedly asked if Angdrogel was appropriate and safe for someone with a history of prostate cancer. I asked if it amounted to playing with fire. The urologist assured me that a number of studies showed that it was perfectly safe. Maybe this PSA rise had nothing to do with the testosterone, but I guess I'll never know.
Androgel, or one of its equivalents, may be appropriate even now. I was on TRT for some years prior to my PCa diagnosis. I won't go through the whole story of the docs who said No More T, but I will tell you that once I learned who to consult, my RO, my uro and I have stayed the course and I remained on TRT before diagnosis, during treatment, and now after treatment. In some cases this is appropriate, but certainly not in all cases.
I suggest you do a web search for "Saturation Theory"+"Morgentaler". Dr. Morgentaler is the specialist in Boston who has spent the last 20 years or so studying the interactions between T and PCa, etc. He is widely published, and is affiliated with Harvard University. I went to Boston to be evaluated by Dr. Morgentaler, then he wrote to my RO and uro, giving his recommendations. With his input, they agreed to manage my care, including ongoing TRT. He will consult via telephone but will only make written ("official") recommendations when he has the chance to interview and examine the patient. If you're interested, he is very approachable.
