Can chlamydia cause a prostate infection? or what are the common causes?

Prostatitis: Yes. But so can many of the common urethral and bladder bacteria. Prostate infection is complicated by inflammation. The prostate gland does not have a great blood supply so while being treated you need to keep the prostate empty. Some times if Azithromycin is not effective another more broad spectrum antibiotic is needed.

More common causes : Most commonly it is due to broad group of bacteria known as gram negative rods, e. Coli being the most common. Chlamydia is rarely seen is clinical practice since routine lab tests (gram stains & bacterial culture) do not detect it. A urinary or prostate secretion antigen test would be needed.
