title: The effect of enrofloxacin on sperm quality in male mice.
abstract: Current study was designed to evaluate toxic effects of enrofloxacin on male mice reproductive system. In the treatment group enrofloxacin was administered subcutaneously to male mice at a fixed dose of 150 mg/kg once daily for 15 days, whereas saline solution was given in the same regimen in the control group for the same period. Mice were sacrificed on day 15 and analyzed for sperm quality. In addition to routine examination of sperm material, spermatogenetic activity and organization of each animal were graded according to Johnsen's scoring to assess the spermatogenesis relying on seminiferous tubule cross-section scores. A significant decrease in both epididymal sperm count and sperm motility besides abnormal spermatozoa rate were observed in enrofloxacin group compared to controls (P < 0.01, for all). Johnsen's score in control mice were better than those in treatment group (P < 0.01). These results suggested that a fixed 150 mg/kg dose of enrofloxacin would lead disruption of spermatogenesis in the testes causing deterioration of motility and content of sperms as well as morphological abnormalities.
