Medical/biological Study (experimental study)

Radio frequency electromagnetic radiation (RF-EMR) from GSM (0.9/1.8GHz) mobile phones induces oxidative stress and reduces sperm motility in rats. med./biol.

By: Mailankot M, Kunnath AP, Jayalekshmi H, Koduru B, Valsalan R
Published in: Clinics (Sao Paulo) 2009; 64 (6): 561 - 565 ( open external web page full article, open external web page PubMed Entry )

Aim of study (according to author)
To evaluate the effects of radiofrequency electromagnetic fields from mobile phones on free radical metabolism and sperm quality in reproductive tissue of rats.
Background/further details:
Rats were divided into a control group and an exposure group with six animals per group.

Endpoint

Exposure
General category: mobile phone, digital mobile phone, GSM

Field characteristicsParameters
900 MHz O - 1.8 GHz O
exposure duration: continuous for 1 h/day on 28 days

Exposed system:
animal (species/strain): rat/Wistar albino
whole body exposure

Methods
Endpoint/Measurement parameters/Methodology

investigated material: sperms and supernatants of tissue homogenates
investigated organ system: reproductive system

time of investigation: after exposure

Main outcome of study (according to author)
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.
