Metronidazole (MTZ) has negative effects on sperm analysis and testis structure. Curcumin is the principal curcuminoid found in turmeric and exhibits antitumor, anti-inflammatory, and anti-infectious activities with low toxicity. To evaluate stereological changes of seminiferous germinal epithelium by MTZ and ameliorative effects of curcumin, Balb-c mice were divided into 6 groups. The control, second, third, fourth, fifth, and sixth groups were administrated distilled water, high doses of MTZ (500 mg/kg/day), MTZ (500 mg/kg/day) + 100 mg/kg/d curcumin, therapeutic doses of MTZ (165 mg/kg/day), MTZ (165 mg/kg/day) + 100 mg/kg/day curcumin, and 100 mg/kg/day curcumin, respectively. Testis weight, testis volume, total epithelial volume, spermatocytes, and spermatid number showed a significant reduction in MTZ-treated (high or therapeutic doses) animals in comparison with the controls. Curcumin can protect spermatocytes after high or therapeutic doses of MTZ treatment. But curcumin is able to protect the other parameters only in the mice receiving therapeutic doses of MTZ. The total number of sertoli cells and spermatogonia did not show any significant difference in the mice that received MTZ. MTZ can reduce germinal epithelium volume and the number of spermatocytes and spermatids. Ameliorative effects of curcumin can mainly be observed in the mice receiving therapeutic doses of MTZ.
