Study type: Medical/biological study (experimental study)

Effect of long-term exposure of 2.4 GHz radiofrequency radiation emitted from Wi-Fi equipment on testes functions. med./bio.

Published in: Electromagn Biol Med 2015; 34 (1): 37-42

Aim of study (acc. to author)

The effects of chronic exposure of male rats to a 2.4 GHz electromagnetic field on the reproductive system should be investigated.

Background/further details

Rats were divided into 2 groups (n=8 each): 1) exposure and 2) sham exposure.

Endpoint

Exposure

Exposure Parameters
Exposure 1: 2.4 GHz
Exposure duration: continuous for 1 year (24 h/day)

Exposure 1

Main characteristics
Frequency 2.4 GHz
Type
Charakteristic
Exposure duration continuous for 1 year (24 h/day)
Additional info signal was declared as WiFi
Exposure setup
Exposure source
Chamber plexiglass cage (55 x 32 x 20 cm)
Setup generator with antenna was used to represent exposure to Wi-Fi systems; rats were kept freely in the cage, 50 cm away from the antenna; ambient temperature of 22°C and relative humidity of 45% were maintained
Sham exposure A sham exposure was conducted.
Additional info study was performed in Faraday cages to eliminate outdoor electromagnetic fields
Parameters
Measurand Value Type Method Mass Remarks
power 50 mW effective value - - emission power
SAR 4,880 µW/kg mean measured and calculated - point value for testes and prostate
SAR 2,420 µW/kg mean measured and calculated 1 g for testes and prostate
SAR 1,020 µW/kg mean measured and calculated 10 g for testes and prostate

Main outcome of study (acc. to author)

The amount of head malformations in sperms was significantly increased, whereas the weights of the epididymis and seminal vesicle, seminiferous tubules diameter and tunica albuginea thickness were significantly decreased in the exposure group compared to the sham exposure group. All other parameters did not show any significant differences between the groups.
The authors conclude that chronic exposure of male rats to a 2.4 GHz electromagnetic field could influence some parameters of the reproductive system with possibly detrimental consequences.
