Effects of Vernonia cinerea on reproductive performance in streptozotocin-induced diabetic rats

چکیده
The present study investigated the effects of Vernonia cinerea (VC) on the reproductive function in streptozotocin (STZ)-induced diabetic male rats. Six-week-old male Sprague-Dawley rats were randomly divided into four groups: group 1, normal control rats; group 2, diabetic untreated rats; group 3, diabetic rats treated with VC (10 mg/kg); and group 4, diabetic rats treated with VC (40 mg/kg). Diabetes mellitus (DM) was induced by intraperitoneal injection of STZ (60 mg/kg). All animals were treated for 30 consecutive days. Body weight, blood glucose, food intake, epididymal sperm parameters, testicular microstructure and serum testosterone levels were evaluated. VC treatment significantly restored the sperm motility and testosterone concentration, and decreased the testicular histopathological changes in DM rats. Moreover, high-dose VC exhibited an antidibetic activity and significantly improved the sperm count. In conclusion, we found, for the first time, that administration of VC significantly restored the testicular function and testosterone concentration in diabetic male rats.

متن کاملThe effects of crocin on the serum levels of sex hormone and NO in streptozotocin – induced diabetic rats.
Background and Aim: Diabetes can lead to reduced fertility in men by production of free radicals. Crocin (the effective component of saffron) with its antioxidant property can be effective in elimination of free radicals. We evaluated the effects of crocin on the reproductive parameters of the STZ –induced diabetic male Wistar rats. Materials and Method: Rats were made diabetic with...
