Ameliorating effects of selenium nanoparticle coated by gallic acid on histological and biochemical parameters of testis in azoospermic rat model

Abstract

This study was designed to examine the effects of selenium nanoparticles (SeNPs) coated with gallic acid (GA) on testis in azoospermic rats. Thirty-six adult Wistar rats were assigned to six groups: control (1 ml intraperitoneal (i.p.) phosphate-buffered saline (PBS) for 7 consecutive days), SHAM (single i.p. injection of 1 ml of 8 % dimethyl sulfoxide (DMSO)), BUS (single i.p. injection of busulfan (BUS) 30 mg/kg body weight), GA (single i.p. injection of BUS 30 mg/kg on day 1, 100 mg/kg body weight GA from days 2–7), SeNPs (single i.p. injection of BUS 30 mg/kg on day 1, 0.5 mg/kg body weight SeNPs from days 2–7), and SeNPs-GA (single i.p. injection of BUS 30 mg/kg on day 1, 0.5 mg/kg body weight SeNPs-GA from days 2–7). Subsequently, serum levels of testosterone and insulin-like growth factor-1 (IGF-1), antioxidant markers, sperm parameters, and histological parameters were evaluated. The results showed that BUS injection induced azoospermia in rats by causing oxidative stress and testicular tissue damage. In contrast, co-administration of SeNPs and GA showed significant improvements in testosterone and IGF-1 levels, antioxidant status, testicular tissue characteristics, and sperm parameters. Overall, the findings suggest that GA-coated SeNPs offer therapeutic potential in BUS-induced azoospermic models.
