Dams were divided into five groups (20 animals/group): cage control, sham exposure group and three different exposure groups (with SAR levels of 0.08, 0.4 and 4 W/kg). Five dams per group were sacrificed and five female fetuses were investigated on day 20 of pregnancy (one day before expected delivery). Additionally, 15 dams per group and their offspring were observed for 28 days after delivery.

Female rats were randomly distributed into five groups with 20 animals per group.
|ばく露時間||2 h/day, 6 days/week for 18 days|
|チャンバの詳細||cubic reverberation chamber (150 x 150 x 150 cm)|
|ばく露装置の詳細||six antennas (70 W) provided uniform exposure; cages were placed in a 40 x 40 x 40 cm³ volume at the center of the chamber|
|Sham exposure||A sham exposure was conducted.|
For all experimental conditions, no abnormalities were noted in the pregnant rats and no significant signs of toxicity were observed in the prenatal and postnatal development of the pups, even at the highest level of 4 W/kg. In conclusion, no teratogenic effect of repeated exposures to the WiFi wireless communication signal was found.
