Pro-oxidant effect of vitamin C coadministration with bisphenol A, nonylphenol, and octylphenol on the reproductive tract of male rats.
This study was performed to investigate whether bisphenol A (BPA), nonylphenol (NP), and octylphenol (OP) induce oxidative stress on the reproductive tract of male rats and if coadministration of vitamin C can prevent any possible oxidative stress. Wistar male rats were divided into seven groups as control (vehicle; olive oil), BPA, NP, OP, BPA+C, NP+C, and OP+C. BPA, OP, and NP groups (25 mg/kg/day) were administered orally to rats three times a week for 45 days. In BPA+C, NP+C, and OP+C groups, vitamin C (60 mg/kg/day) was administered orally along with BPA, OP, and NP (25 mg/kg/day) treatments. Malondialdehyde (MDA) appeared at significantly higher concentrations in BPA-, NP-, and OP-treated groups, when compared to control group. No significant decrease was observed in testes MDA levels of vitamin C coadministrated groups, compared with BPA, NP, and OP treatment groups. Decreased levels of reduced glutathione (GSH) were found in testes of BPA-, NP-, OP-treated rats. No significant increase was observed in testes GSH levels of BPA+C, NP+C, and OP+C groups, compared with BPA, NP, and OP treatment groups. Histological examination showed that vitamin C coadministrated groups had much more congestion areas, atrophy, and germinal cell debris in testes than those observed in other groups. Abnormal sperm percentages of BPA, BPA+C, NP+C, and OP+C groups were increased. In conclusion, the present results demonstrated that BPA, NP, and OP generate reactive oxygen species that cause oxidative damage in testes of rats. Coadministration of vitamin C aggravates this damage.
