RECENT sexual intercourse has been established as an important risk factor for acute cystitis in women.1-3 Intercourse probably predisposes women to infection by facilitating entry of urethral Escherichia coli into the normally sterile bladder, not by actual venereal transmission of bacteria.2,3 The role of sexual intercourse as a predisposing factor for urinary tract infections (UTIs) in men has not been studied, to our knowledge, but is generally believed to be unimportant. We describe a 54-year-old man who experienced acute cystitis that was temporally related to recent sexual intercourse and was caused by an E coli strain with the same antibiotic susceptibility pattern and serotype that had just previously infected his wife.
