The present study has revealed the effect of Moringa oleifera leaves extract against electromagnetic field induced impairments. Forty-two adult white Albino male rats, weighting 150-180 g were involved in this study and divided into six equal groups. The first group was the control while the second group was daily supplemented with 200 mg/kg Moringa oleifera leaves extract orally for six days. The third group was exposed to an electromagnetic field of 1.5 mT, 50 Hz for 9 hours. The other three groups were exposed to an electromagnetic field of 1.5 mT, 50 Hz for 9 hours, and received the Moringa oleifera leaves extract in different supplemented ways. Blood samples were collected for the absorption spectrum of hemoglobin molecules analysis and serum total testosterone was studied. Samples of testes were taken for histopathological observations. The results showed that exposure of the animals to the electromagnetic field resulted in changing the absorption spectrum of hemoglobin, a highly significant reduction in testosterone level, and degenerative changes in testes. All these induced changes were decreased in groups treated by Moringa oleifera leaves extract in all ways. So through this study, one can conclude that damages induced by exposure to the electromagnetic field can be decreased by Moringa oleifera leaves extract.
