I'm share some skepticism. While I agree with their belief that prostates suffer from unappreciated "mechanical" issues, I'm less convinced of their method of resolution.
For my own worthless anecdote, I've noted that my (usually post-orgasm) prostate pain was significantly improved when I started taking Losartan - a anti-hypertension medication (angiotension II blocker (ARB)). The day after I started taking it, I could feel my prostate like never before (then that initial sensation went away), so there was very clearly an associative mechanism of action.
