  is human urine sterile????
Dear Clint,
Yes, urine is considered sterile in the sense that it normally should not contain bacteria.  Bacteriuria is the presence of bacteria in the urine, that is not attributed to contamination from the skin, foreskin, or vagina.  Although urine produced freshly by the kidneys is sterile (unless the individual has a kidney infection), it can become infected with bacteria or yeast in the presence of a urinary tract infection.  Sometimes an individual may have bacteria in the urine in the absence of symptoms of a urinary tract infection (asymptomatic bacteriuria).  I hope this answers your question regarding the sterility of urine.  Wish you the best.
