This narrative review discusses sex-dependent responses to magnetic field polarity and direction in living systems and proposes a unified framework integrating magnetobiology with sex-based physiology. It describes potential interaction mechanisms (e.g., ion channel modulation, radical pair dynamics, ion cyclotron resonance) and notes that some reported outcomes differ by sex depending on polarity. The author suggests that failing to account for polarity and direction could miss relevant health risks and calls for experimental paradigms that treat sex as a key biological variable.

This animal study tested whether short-term ELF-EMF exposure alters respiratory physiology in rats. Twenty Wistar albino rats were assigned to control or EMF exposure (50 Hz, 0.3 mT for 2 minutes) with respiratory parameters measured before, during, and after exposure. The study reports changes during exposure (lower respiratory rate and higher cycle duration, inspiration time, and tidal volume) but no differences after exposure, and it frames the findings as relevant to EMF safety and potential health risks.

This animal study exposed pregnant Sprague Dawley rats to a 900 MHz electromagnetic field for 1 hour daily throughout gestation and assessed offspring outcomes postnatally. Sciatic nerve analyses at postnatal day 60 indicated persistent morphological alterations attributed to prenatal EMF exposure. However, the reported changes were not severe enough to significantly affect measured functional outcomes (including electrophysiology and locomotor tests).
