Background: Male reproductive toxicity has been linked to cyclosporine, a commonly used immunosuppressive drug for the prevention of organ rejection in patients undergoing renal transplant. The goal of this study was to elucidate how lutein protects male testicles from cyclosporine-induced damage.
Methods: Thirty adult male Wistar rats were randomly allotted to five groups, each with six animals. Rats in groups 1 and 2 were given saline (2 mL/kg/day p.o) and corn oil (2 mL/day p.o) respectively. Rats in groups 3 and 4 were given lutein (40 mg/kg/day p.o) and cyclosporine (40 mg/kg/p.o./day), while rats in group 5 were given a combination of cyclosporine (40 mg/kg/day p.o) and lutein (40 mg/kg/day p.o). At the end of the fourth week, sperm indices, serum hormones, testicular steroidogenic enzymes [3 and 17 beta-hydroxysteroid dehydrogenases (3?-HSD and 17?-HSD)] and enzyme markers of spermatogenesis [lactate dehydrogenase (LDH-X), sorbitol dehydrogenase (SDH), gamma glutamyl transferase (?-GT), acid phosphatase (ACP) and alkaline phosphatase (ALP)] were assayed. The testis of each rat was also investigated for histopathological abnormalities and germ cell count.
Results: Lutein attenuated cyclosporine-induced sperm impairment. In rats treated with cyclosporine, lutein reduced LDH-X, SDH, ACP, ?-GT; raised LH, FSH, testosterone, 3ß-HSD, 17ß-HSD, ALP levels, and improved spermatogenesis.
Conclusion: These results suggest that lutein attenuates cyclosporine-induced testicular impairment through modulation of androgenic hormones and enzymes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
