So if someone after two weeks had their semen consistency change to be completely watery, would it be their eyes that produced the nocebo effect or? Or how is the doctor who went on it for a few months, lost erections, then gained them back after quitting explained by a nocebo?

Again, I've heard at least 5 of these first-hand, which is kind of wild for a drug I've probably only talked to 20 people about in total.

We're terrible at detecting changes over long periods of time. If anything I'd think long term users would be much more liable to bias.
