Ameliorative effect of Alpinia officinarum Hance extract on nonylphenol-induced reproductive toxicity in male rats.

Abstract

Nonylphenol (NP), an endocrine-disrupting chemical, interferes with reproductive function and induces oxidative stress in different organs, including the testis and prostate. Alpinia officinarum Hance (ALP), a plant species of the Zingiberaceae family, has proven antioxidant properties. This study aimed to evaluate the effect of the alcoholic extract of ALP treatment on NP-induced reproductive toxicity and oxidative stress in male rats using biochemical and histopathological biomarkers. Our experimental groups were defined as follows: oil treatment (control), NP 10mg/kg, ALP 10mg/kg (ALP HD), NP+ALP 5mg/kg (NP+ALP LD) and NP+ALP 10mg/kg (NP+ALP HD). NP administration caused significant cytotoxicity and a significant increase in oxidative stress prostate-specific antigen (PSA) levels accompanied by a significant reduction in testosterone levels. The relative weight of the testis of both NP+ALP LD and NP+ALP HD groups was significantly decreased compared to the control group. Histopathological evaluations revealed destructive effects in testis and prostate tissue samples. In conclusion, ALP administration improved cytotoxicity, oxidative stress, testosterone and PSA levels, and testis and prostate tissue destructive effects induced by the NP in male rats.
