Scholarcy highlights

  • The present study investigated the hormones concentrations and gonads alterations of Clarias gariepinus caused by sublethel concentrations of 4-nonylphenol
  • Reduction in the gonadosomatic index was evident with increase of sublethal doses of 4-nonylphenol
  • The histopathological changes of NP-treated were recorded in gonads of Clarias gariepinus reflecting their sensitivity to NP-estrogenic like effects
  • ► We tested three sublethel concentrations from 4-nonylphenol on the hormonal activities of Clarias gariepinus. ► 4-nonylphenol caused hormonal disruption by increasing and decreasing hormonal activities. ► Many alterations in the reproductive organs indicating the estrogenic effect of this chemical pollutant
