title: Concentration of ofloxacin and ciprofloxacin in human semen following a single oral dose.
abstract: A single oral dose of ofloxacin (400 mg.) or ciprofloxacin (500 mg.) was administered to each of 40 men. The mean concentrations of ofloxacin in semen exceeded those of ciprofloxacin at 1 hour (p = 0.035) and 24 hours (p = 0.028), while the levels of the 2 drugs at 2 and 4 hours were comparable. Semen concentrations of ofloxacin but not ciprofloxacin exceeded the reported minimal inhibitory concentration of Enterobacteriaceae, Chlamydia trachomatis and genital Mycoplasma species 24 hours after dosage.
