Urethra

When urinating, urine flows from the urinary bladder through the urethra to the outside. In women, it is approx. 4 cm long and lies against the front wall of the vagina. In men, it is approx. 25 cm long, is surrounded by the prostate and then runs along the underside of the penis into the glans. During ejaculation, the sperm is released into the urethra in the area of the prostate. In women, the sphincter in the pelvic floor is located below the urinary bladder; in men, it is below the prostate.
