The antioxidant properties of resveratrol on sperm parameters, testicular tissue, antioxidant capacity, and lipid peroxidation in isoflurane-induced toxicity in mice

Abstract

This study explores whether resveratrol effectively protects the reproductive system against isoflurane-induced toxicity in testicular tissue. In this experiment, we randomly divided 60 adult male C57BL/6 mice into six groups ( n = 10). Five consecutive days per week, mice were exposed to 1.5% isoflurane for 1 h/day and were given 50 and 100 mg/kg resveratrol. After 35 days (the completion of the mouse spermatogenesis period), the left testis was removed for histomorphometric evaluations, while the right testis was used to determine the Capacity of total antioxidants and lipid peroxidation. To analyze the Parameters of sperm, chromatin maturation, and DNA fragmentation, the left caudal epididymis was used. Based on a one-way analysis of variance (ANOVA), we considered a difference in means of 0.05 to be significant (P0.05). Compared to the control group, the isoflurane group showed a significant decrease in testicular weight, volume, sperm parameters, and tissue histomorphometry. Comparatively, to the control group, malondialdehyde levels increased, and the total antioxidant capacity decreased significantly. Resveratrol improved all of the above parameters in the simultaneous treatment groups compared to the isoflurane group. It did not, however, reach the level of the control group in all cases. It has been demonstrated that resveratrol, with its powerful antioxidant properties, reduces the reproductive toxicity of isoflurane by inhibiting free radicals and increasing the testicular tissue's antioxidant capacity.
