I suffered badly with UTI's a few years ago and several courses of antibiotics were needed to shift them. Fortunately I've not had too many problems since then. I know the doctors got very excited about it because they were signed up to the medical textbook myth that men don't get water infections. Well I'm sorry but I know otherwise, both from my own experience and from other guys I've discussed it with. Whilst it's not effective as a treatment for the problem, I'm told cranberry juice is very good at deterring it in the first place as are cranberry tablets and antitis tablets.
