I agree with what everyone said, you've got everything pretty much covered!
Along my travels, I have heard about testing testosterone levels, just like Kidneys, hearing, vision, and others that can be impaired from treatment, namely chemo. High doses of Cisplatin i have read can cause low levels of testosterone, fertility problems and such, but so can other conditions, even age. i think more may be researched with testicular cancer. I had my levels checked after treatment, not my request, and I'm not sure which doctor did, may have been the nephrologist, and levels were found low, as were vitamin D, B12, hemaglobin, amongst others, and brought within range.
