Study type: Medical/biological study (experimental study)

Effect of ELF magnetic fields on lipid peroxidation, sperm count, p53, and trace elements. med./bio.

Published in: Med Sci Monit 2006; 12 (11): BR366-BR371

Aim of study (acc. to author)

To investigate the effects of extremely low frequency magnetic fields on sperm count, malondialdehyde concentration, the histology of such organs as the testes, brain, liver, and kidney tissues, p53 immune response of bone marrow, and the serum concentrations of trace elements in rats.

Background/further details

16 male rats were examined, eight exposed and eight control animals.
