There are no data to answer this question with certainty. However, male urinary or genital bacterial infections often are difficult to eradicate; often the prostate is infected, and sometimes it takes more prolonged treatment to clear prostate infections. It would be wise to have another culture 2-3 weeks after completing levofloxacin. If that's negative, you can be confident you were cured.
