<b>DNA integrity and sperm morphology of Wistar rats exposed to low frequency electromagnetic fields during different periods of development</b> - doi: 10.4025/actascibiolsci.v33i3.5417

Abstract

The society’s exposure to electromagnetic fields (EMF) has been growing considerable due to the great technological expansion observed in the last few years. Generation as well as distribution and use of electric energy can generate low frequency electromagnetic fields (50 and 60 Hz). Issues have been demonstrating that EMF exposure could provoke significantly physiological changes, however, the extension of EMF effects weren’t totally clarified. The major objective of this issue was to evaluate the EMF (60 Hz and 1 mT) effects on DNA integrity and sperm morphology in Wistar rats with mature sexuality that were exposed during different stages of testicular development. According to our results, EMF did not change DNA integrity, but we could observe morphological changes in sperm after exposure to EMF. These changes in sperm morphology may reduce the reproductive potential. Therefore, we should consider the EMF as a potential risk to public health, recommending the implementation of further research seeking to establish safe levels of exposure to EMF.
