<s>[INST] Why are UTIs more common in women than men? [/INST] Usually the urine is sterile. UTIs are caused by bacteria entering the urinary tract through the urethra. Women contract these infections more frequently than men because the urethra in women is significantly shorter than in men; about 1.5 inches for women and 8 inches for men.
