To investigate the effects of an exposure to a Wi-Fi signal on the reproductive system of male and female rats.
The male rats were exposed during sexual maturation for 3 weeks before mating, the females for 2 weeks (n=36, respectively). After the mating, couples were exposed for 3 more weeks. One day before the expected delivery, the dams were sacrificed and the fetuses were removed from the uterus and examined. Also, the male rats were sacrificed and their sexual organs were examined.
Three groups were examined: 1.) sham exposure, 2.) exposure to a specific absorption rate of 0.08 W/kg and 3.) exposure to a specific absorption rate of 4 W/kg.

No influence of the exposure on the body weight and the male and female reproductive organs was found as well as no malformation in the fetuses.
The results provide evidence of an absence of effects of Wi-Fi exposure on male and female rat fertility.
