I want to start a testosterone replacement therapy. My main concern is the impact to my kidneys.
One year ago I was found with a cancer in one of my kidneys. I underwent a partial nephrectomy which succeeded. Now, I have 1 whole kidney and 0.6 of the other. They work properly and I do not have any sign of cancer (whereas I will be doing exams every 6 months for the next 3 years).
I have to add the whole kidney has 2-3 cysts, but apart from that my kidneys work completely properly.
My questions are: Is the use of testosterone toxic for kidneys? Does my condition (apart for the extra burden due to the deficit in volume of kidneys) entail higher risk? Would you suggest the use of testosterone in such a case?
