Prostatitis is when the prostate is inflamed, usually because of an infection. It can also be caused by injury to the prostate, or by some autoimmune diseases. Autoimmune diseases cause the body’s immune system to damage healthy cells in the body.

In some men, prostatitis may not cause any symptoms. Other men may have symptoms, including:

  • repeated urine infections (infections in your pee) – this can be treated with antibiotics
  • pain in or around the end of the penis, testicles, inner thighs, the area between the testicles and back passage (perineum), or the lower back
  • pain during ejaculation or blood in the ejaculated semen.
