Exposure to a 2450 MHz Wi-Fi signal for 1 hour per day did not cause deleterious effects on reproductive organs or fertility, and no macroscopic fetal abnormalities were observed.

Plain English Summary

Summary written for general audiences

Researchers exposed male and female Wistar rats to a 2450 MHz Wi-Fi signal for 1 hour per day, 6 days per week. Exposure lasted 3 weeks for males and 2 weeks for females before mating, then continued for 3 more weeks during gestation. No deleterious effects on reproductive organs or fertility were observed, and no macroscopic abnormalities were found in fetuses even at 4 W/kg.

Why This Matters

Fetuses were examined on the day before delivery. They were assessed for lethality, abnormalities, and clinical signs.

Study Details

We evaluated the effects of exposure to the 2450MHz Wi-Fi signal (1h/day, 6days/week) on the reproductive system of male and female Wistar rats, pre-exposed to Wi-Fi during sexual maturation.

Exposure lasted 3 weeks (males) or 2 weeks (females), then animals were mated and couples exposed fo...

In our experiment, no deleterious effects of Wi-Fi exposure on rat male and female reproductive orga...
