Testicular Morphological Changes Produced by Fluoroquinolones in Adult Male Albino Rats

Abstract

Abstract

Objectives:  The objective of this research work was to observe the testicular morphological changes produced by fluoroquinolones in the reproductive organs of adult male albino rats, and to see whether these changes are reversible after discontinuation of the drugs.

Materials and Method:  Eighty adult male albino rats weighing 200 – 300 gms were randomly selected and divided into four groups i.e. A, B, C & D, having 20 animals in each group. A, B & C, were the experimental groups & D served as control group. All the groups were further divided into sub groups 1 & 2. Three fluoroquinolones i.e. Ciprofloxacin (135 mg / kg / day), Ofloxacin (75 mg / kg / day) & Enoxacin (12.5 mg /
kg/ day) were given to the groups A, B & C respectively for 42 days. Animals of group D received dis-tilled water only. Animals of sub groups A1, B1, C1 &

D1 were sacrificed on 42^nd day and testicular tissue was obtained for morphological study. Animals of sub

groups A2, B2, C2 & D2 were sacrificed on 84^th day and testicular tissue for morphological changes was taken. No of leydig cells, height of epithelium and diameter of seminiferous tubules were taken as experimental parameters for morphological changes.

Results:  The study indicated statistically significant (P < 0.05) decrease in height of epithelium, diameter of seminiferous tubules and no. of leydig cells in experimental groups as compared to the control groups.

Conclusion:  The changes observed in morphology could lead to decrease in sperm count and testosterone levels. This study suggests gonadotoxic potentials of fluoroquinolones and adds concern to the indiscriminate and widespread use of fluoroquinolones and recommends more rational use of these drugs.
