Introduction: Diabetes mellitus is accompanied with enhanced oxidative stress and reduced activity of the antioxidant defense system. Due to the significant role of enhanced oxidative stress in the development of ovarian damage in diabetics, this study was conducted to evaluate the effect of chronic administration of zinc sulfate on oxidative stress markers in ovarian tissue of diabetic rats.
 
Materials & Methods: This experimental study was performed on 24 female Wistar rats weighing 120 -150 gr. The rats were divided into four groups: normal control (NC), diabetic control (DC), and two diabetic groups treated with zinc sulfate (15 and 30 mg/kg). Zinc sulfate was administered one week after streptozotocin injection for 28 days (via gavage daily). At the end of the experiment, the body weight and blood sugar of the animals were measured and compared with the weight and blood glucose measured in the week before the study. Also malondialdehyde levels (MDA), catalase activity (CAT), and total antioxidant capacity (TAC) as oxidative stress indices in ovarian tissue were measured. In the end, the data were analyzed statistically using the SPSS software, and ANOVA and Tukey’s tests were analyzed.
 
Findings: Chronic uncontrolled Hyperglycemia (blood glucose greater than 300 mg/dl) significantly increased the levels of MDA in diabetic animals compared to normal animals (p<0.05). Also, hyperglycemia caused a decrease in the activity of the catalase enzyme and the levels of total antioxidant capacity (TAC) in diabetic animals (p<0/05). and Hyperglycemia reduced the activity of the catalase enzyme and ultimately the capacity The total antioxidant of the total antioxidant (TAC) of diabetic animals (p<0/05). Administration of zinc sulfate by increasing the activity of the catalase enzyme reduced the levels of MDA in diabetic animal ovary tissue in comparison with the diabetic control group, but could not significantly affect TAC.
 
Discussion & Conclusions: Administration of zinc sulfate for four weeks in a dose-dependent manner reduces oxidative stress indexes in ovarian tissue of diabetic rats.
