Definition: The urethra is a small tube that allows urine to flow out of the body from the bladder. In men, the urethra also provides an outlet for sperm out of the body through the penis. The urethra in women is much shorter, leading from the bladder out of the body through a small opening located just above the vagina.
Urinary tract infections (UTI) often originate when bacteria enters the urethra. Sometimes, during sexual activity, rubbing of the urethra occurs which can potentially led to UTI.
