Exposure duration: continuous for 1 year (24 h/day)
|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|

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.
