Chronic prostatitis/pelvic pain syndrome, inflammatory, is an inflammation of the prostate that causes pain in the abdomen, testicles, or tip of the penis, urination problems, and painful ejaculation. It is the most common type of prostatitis.

Its cause often cannot be determined. Bacteria are usually not detected in the urine, and fever, chills, or other signs of an infection are not present.

Chronic prostatitis/pelvic pain syndrome, inflammatory, used to be called nonbacterial prostatitis.
