Many doctors are not so keen on laughing in these types or situations because it's often very emotionally charged. That "joke" can often be to cover up the anxiety and not an actual joke. Some doctors are better than others at reading the room. But don't think your joke sucked, that was hilarious. The doctor probably told a colleague later on and laughed a bit.

Honestly you might as well just say that you have no idea if it increases the risk.

PSA is a horrible way of saying if it increases the risk for cancer. There is no way of determining if it increases the risk on that single test over such a short period.

Digital rectal exam is almost entirely useless unless you have a clearly pathological prostate. Small changes are hard/impossible to detect and it's extremely user dependent.

I am all for a male contraceptive pill but are you trying to mislead people intentionally or are you just dumb?

That is not how physics works...
