Study type: Medical/biological study (experimental study)

Whole body exposure of rats to microwaves emitted from a cell phone does not affect the testes. med./bio.

Aim of study (acc. to author)

To investigate the effects of radiofrequency radiation emitted from cellular phones on the lipid composition, malondialdehyde concentration, p53 immune reactivity, sperm count, morphology, histological structure of testes, and the rectal temperature of rats.
