Prostatitis is swelling and inflammation of the prostate gland, a walnut-sized gland situated directly below the bladder in men. The prostate gland produces fluid (semen) that nourishes and transports sperm.
Prostatitis often causes painful or difficult urination. Other symptoms include pain in the groin, pelvic area or genitals and sometimes flu-like symptoms.
Prostatitis affects men of all ages but tends to be more common in men 50 or younger. The condition has a number of causes. Sometimes the cause isn't identified. If prostatitis is caused by a bacterial infection, it can usually be treated with antibiotics.
Depending on the cause, prostatitis can come on gradually or suddenly. It might improve quickly, either on its own or with treatment. Some types of prostatitis last for months or keep recurring (chronic prostatitis).
Prostatitis signs and symptoms depend on the cause. They can include:
- - Pain or burning sensation when urinating (dysuria)
- - Difficulty urinating, such as dribbling or hesitant urination
- - Frequent urination, particularly at night (nocturia)
- - Urgent need to urinate
- - Cloudy urine
- - Blood in the urine
- - Pain in the abdomen, groin or lower back
- - Pain in the area between the scrotum and rectum (perineum)
- - Pain or discomfort of the penis or testicles
- - Painful ejaculation
- - Flu-like signs and symptoms (with bacterial prostatitis)
