Published in: Toxicol Ind Health 2016; 32 (2): 328-336

Aim of study (acc. to author)

To evaluate the effects of radiofrequency exposure emitted by a mobile phone on the testes of of rats during the pubertal development.

Background/further details

For this study, 6 rats were exposed and 6 rats were sham exposed.

Main outcome of study (acc. to author)

The histopathological examination of the testes revealed no significant differences between the exposed and the sham exposed rats. Additionally, no significant changes regarding apoptosis, cell proliferation, weight, length and width of testes and the blood parameters occurred.
The authors conclude that radiofrequency exposure emitted by a mobile phone has no deleterious effect on the testes of rats during the pubertal development.
