A male having recurrent UTI is unusual. We need to rule out a few things
1. Have him checked up for diabetes
2. Have him checked for STDs
3. Get a USG KUB done as well, sometimes renal or bladder notes predispose to UTI and vice versa.
Have him checked up with a urologist
as well at a later date. Like I said, a male having UTI is not usual.
Hope this helps
