Salvia officinalis hydroalcoholic extract improved reproduction capacity and behavioral activity in rats exposed to immobilization stress.

Abstract

This study was conducted to evaluate the Salvia officinalis hydroalcoholic extract on fertility capacity and behavioral features in rats exposed to immobilization stress. Male rats were randomly divided into five groups; Control; Stressed rats; and Stressed rats received 50, 100 and/or 200mg/kg bw S. officinalis hydroalcoholic extract. To induce stress, rats were immobilized for 49days and received S. officinalis extract orally. On day 56, we analyzed behavioral tests and evaluated reproduction capacity by measuring LH, FSH, and testosterone. Sperm parameters such as motility, viability, and total count were also determined. Bodyweight changes were also calculated on day 56. Male rats from different groups were mated with healthy female rats. Data showed that the use of 100 and 200mg/kg bw S. officinalis extract in stressed rats increased bodyweight gain and improved behavioral disorders compared to control-matched groups (p<.05). Besides, administration of 100 and 200mg/kg bw S. officinalis extract had the potential to improve sperm parameters and fertility capacity in stressed rats (p<.05). Decreased testosterone levels were blunted in the stressed rats that received plant extract coincided with the reduction of LH and FSH compared to control-matched stressed rats (p<.05). We found neutral effects in stressed rats that received 50mg/kg bw plant extract. Collectively, the hydroalcoholic extract of S. officinalis could improve the fertility capacity and behavioral features under stressful conditions in a dose-dependent manner.
