Ameliorative effects of <i>Saussurea lappa</i> root aqueous extract against Ethephon‐induced reproductive toxicity in male rats

Abstract

This study was designed to evaluate protective effect of Saussurea lappa root aqueous extract against Ethephon (2-chloroethylphosphonic acid)-induced reproductive toxicity in rats. Control group received distilled water. Second group was given S. lappa extract at a dose 50 mg/kg bw. Third group was given Ethephon at a dose 200 mg/kg bw. Fourth, fifth, and sixth groups were given S. lappa extract before, with or after Ethephon administration, respectively. Ethephon intoxication significantly decreased serum levels of follicle stimulating hormone, luteinizing hormone, testosterone, and prolactin. Also, it significantly decreased sperms count, vitality, morphology index, total motility, progressive motility, and proliferating cell nuclear antigen protein expressions in spermatogonia. However, it significantly increased sperms abnormalities, testicular tissue and DNA damages, P53 protein expressions, noprogressive motility, and immotile sperms. In contrast, S. lappa extract ameliorated these alterations. These results indicated that S. lappa had potential preventive and curative effects against Ethephon-induced reproductive toxicity in rats.
