Any bacteria that can cause a urinary tract infection can cause acute bacterial prostatitis.
Infections spread through sexual contact can cause prostatitis. These include chlamydia and gonorrhea. Sexually transmitted infections (STIs) are more likely to occur from:
Certain sexual practices, such as having anal sex without wearing a condom
Having many sexual partners
In men over age 35, E coli and other common bacteria most often cause prostatitis. This type of prostatitis may begin in the:
Epididymis, a small tube that sits on top of the testes.
Urethra, the tube that carries urine from your bladder and out through the penis.
Acute prostatitis may also be caused by problems with the urethra or prostate, such as:
Blockage that reduces or prevent the flow of urine out of the bladder
Foreskin of the penis that cannot be pulled back (phimosis)
Injury to the area between the scrotum and anus (perineum)
Bacterial infections in the prostate can be very painful. The symptoms begin slowly and last three months or longer. See your doctor if you have any of the following symptoms:
blood in the urine or semen
pain or burning with urination
pain with ejaculation
pain with bowel movements
pain in the lower back, between the genitals and anus, above the pubic bone, and in the testicles
foul-smelling urine
Serious complications can arise if an infection isn’t properly treated. Complications include:
an inability to urinate
sepsis, which occurs when bacteria spread into the bloodstream
a prostate abscess, which is a collection of pus that causes inflammation
