What causes prostatitis?
In most cases, inflammation of the prostate gland is caused by infection with bacteria. The most common bacteria is Escherichia coli, but others can also affect the gland.
Many prostatitis cases are associated with sexual activity, and sexually-transmitted infections are a very common baseline diagnosis in patients with prostatitis. This is one of the reasons why prostatitis is more common in young males than older adults.
However, chronic prostatitis and pelvic pain syndrome are more difficult to evaluate. They can be triggered by fungi and viral infections. In some cases, there’s no infection at all, and the trigger is an autoimmune condition, pelvic floor dysfunction, or a neurologic injury.
