研究目的(著者による)

To evaluate the effects of radiofrequency electromagnetic fields from mobile phones on free radical metabolism and sperm quality in reproductive tissue of rats.

詳細情報

Rats were divided into a control group and an exposure group with six animals per group.

研究の主なアウトカム(著者による)

No significant difference was found in total sperm count between the control group and the exposed group. However, exposed rats exhibited a significantly reduced percentage of motile sperms. Moreover, exposure resulted in a significant increase in lipid peroxidation and low glutathione content in the testis and epididymis. Facial temperature was not affected in either group of rats.
In conclusion, the authors speculate that radiofrequency electromagnetic fields from mobile phones negatively affect semen quality and may impair male fertility.
