Abstract
Summary The concentration of ofloxacin was measured in both fractions of split-ejaculate from five volunteers treated with ofloxacin 400 mg/day for 3.5 consecutive days. Concentrations in both fractions were equal, 2.44 mg/l and 2.5 mg/l, respectively indicating that the penetration of ofloxacin into the prostate gland and into the vesical glands are of the same magnitude. Sperm motility was not affected by ofloxacin in a concentration of 4.5 mg/l as tested on fresh ejaculate of 29 andrologic patients. Thus ofloxacin proves to be useful as a potent antibiotic in clinical care for andrologic patients.
