Re: What can I do to prevent a prostate infection? PLEASE READ!
You should not be diagnosing yourself. If you are concerned you have a prostate infection, then see a doctor about it. Wishing an infection to go away won't help. Real prostate infections can be a dickens to get rid of, so you would want to start treating it with antibiotics sooner rather than later.
Saw Palmetto and zinc are good daily supplements for prostate health. As was said, periodic ejaculations can also help. In general, a good healthy diet and exercise can't be beat for overall good health.
