The effect of hydroalcoholic extract of Salvia officinalis on germinal cells of testis tissues in adult male diabetic rats

Diabetes mellitus mediated by oxidative stress creates serious metabolic disorders in testicles. This study aimed to demonstrate the antioxidant effect of Salvia officinalis (SO) on testicular damage in streptozotocin-induced diabetes in male rats.
In this experimental study, 50 male Wistar rats were divided into 5 groups of 10. The control group received water and food, stereptozotocine-treated diabetic (60 mg/kg), SO-treated control (400 mg/kg), SO-treated diabetic (200 mg/kg), and SO-treated diabetic (400 mg/kg). After 28 days, the testis was immediately removed and its sections were stained with Hematoxylin and Eosin and evaluated.
Comparison of histological sections showed the number of cells spermatogonia, primary spermatocyte, spermatid, Leydig and Sertoli in the diabetic group showed a significant decrease as compared with control group. In comparison of SO-treated control group with control group, a significant increase in the number of these cells was observed except for Sertoli cells. The SO-treated diabetic (200 and 400 mg/kg) groups showed a significant increase in the number of these cells as compared with the diabetic group. (p Probably, the antioxidant compounds in extracts of this plant, i.e. sage, are effective in reducing the incidence of diabetes in mice spermatogenesis.
