Influence of microwave exposure on fertility of male rats.

Published in: Fertil Steril 2011; 95 (4): 1500-1502

Aim of study (acc. to author)

To assess the effect of microwave exposure on male fertility of rats, reactive oxygen species content, histone kinase enzyme activity, apoptotic cell number, and cell cycle distribution were investigated in sperm samples of rats exposed to 10 GHz microwaves.
Background/further details: 12 rats were divided into one exposure group (n=6) and one sham exposed group (n=6).

Main outcome of study (acc. to author)

The data showed significant changes in the level of reactive oxygen species (increase), histone kinase enzyme activity (decrease), apoptotic cells (increase), and percentage of G2 phase/mitosis phase cells (decrease) of cell cycle in the exposed group compared with the sham exposed group.
The authors conclude that there is a significant effect of microwave exposure on reproductive parameters in male rats.
