Abstract

Overview

Electromagnetic fields (EMFs) have previously been shown to negatively impact the biology and behavior of humans and animals, but their effects on body growth and brain-derived neurotrophic factor (BDNF) levels have not been thoroughly examined until now.

Objective

The study primarily aims to explore the adverse effects of EMF exposure on spatial learning and motor function in rats, assessing whether physical activity could mitigate the harmful impacts. The innovative aspect involves determining the influence of Wi-Fi EMF on the growth of rat offspring, utilizing measures like body anthropometry and BDNF levels.

Methods

  • Twenty Albino-Wistar pregnant rats were divided into EMF exposed and control groups.
  • Post delivery, twelve male fetuses were selected for detailed growth and BDNF analysis, assessing body length and weight at various developmental stages using precise tools like digital calipers and scales.
  • BDNF levels were determined using ELISA kits.

Findings

Anthropometric data indicated that EMF exposure inhibited body growth in exposed rat offspring. Moreover, a significant decrease in BDNF levels was observed in the EMF group compared to controls, affirming the detrimental effects of EMF on developmental health markers.

Conclusion

Exposure to EMF during pregnancy impairs body growth and BDNF levels in offspring, suggesting significant developmental risks.
