Prenatal and early-life WiFi exposure did not produce measurable oxidative stress or heat-shock protein responses in developing rat brains at the exposure levels tested.
Plain English Summary
Summary written for general audiences
This study examined whether WiFi signal exposure (2450 MHz) during pregnancy and early life affected stress markers in rat brains by measuring 3-Nitrotyrosine and heat-shock proteins (Hsp25 and Hsp70) using immunohistochemistry. The researchers found no significant differences in these biomarkers between rats exposed to WiFi at various power levels (0-4 W/kg) and sham-exposed controls, suggesting repeated WiFi exposure during gestation and early postnatal development did not cause detectable adverse effects in young rat brains.

No harmful effects were observed on male or female rat fertility, mating success, or fetal development after daily WiFi exposure during sexual maturation and pregnancy periods.
The study used 2.45 GHz WiFi signals at exposure levels up to 4 watts per kilogram, which is significantly higher than typical home WiFi exposure levels.
Rats were exposed for one hour per day, six days per week, during sexual development and throughout the mating and pregnancy periods.
No macroscopic abnormalities or birth defects were observed in fetuses from parents exposed to WiFi radiation, even at the highest exposure levels tested.
The study used one hour daily exposure, which is much less than typical home WiFi that operates continuously, but at higher power levels than most household routers.
