Study The Protective Effect of Quercetin on Testis Histological Changes and Spermatogenesis Indexes in Adult Mice Following Treatment with Dexamethasone

Abstract

Introdution: Dexamethasone is used in inflammatory disease, leukemia and nausea, which increases the oxygen free radicals in the testis as a consequence. The aim of this study was to study the protective effect of Quercetin as a plant flavonoid and strong antioxidant on testis histological changes and Spermatogenesis indexes in adult mice following treatment with Dexamethasone. Methods: 24 adult male mice (NMRI) were divided into 4 groups (n=6): control, Dexamethasone (7mg/kg/day), Quercetin (50mg/kg/day) and Dexamethasone + Quercetin. 7 days after intra peritoneal treatment, the right testis were removed, fixed, sectioned, processed and stained with Heidenhain’s Azan method, testis histological changes and spermatogenesis indexes were studied by stereological techniques. Data were analyzed using one-way ANOVA and the means were considered significantly different (P0.05). Conclusion: Our results indicated that Quercetin as a strong antioxidant can reduce the destructive effects of dexamethasone on the histology of testis tissue and Spermatogenesis indexes in mice. Therefore, Quercetin is suggested as a therapeutic supplement in regimens containing Dexamethasone
