Actually, I was interested in your experience with other prostate patients, which is why I asked. I did ask Perplexity before asking you, but I received a pretty much opposite answer: "For men who have undergone a prostatectomy (removal of the prostate), riding a bike is generally not expected to cause an elevated PSA level because the prostate—the source of PSA—is no longer present. PSA is a protein produced by prostate cells, so without the prostate gland, PSA should be undetectable or very low.". But I suspected there'd be some feedback in the meetings you attend. Sorry if my question seemed trite; I won't make that mistake again.
