High EMF exposure during pregnancy dramatically reduced male births to just 23.5%, suggesting male fetuses are especially vulnerable to electromagnetic radiation.

Plain English Summary

Summary written for general audiences

Danish researchers studied 586 pregnancies among physiotherapists exposed to high-frequency electromagnetic radiation from medical equipment. They found that mothers with high EMF exposure gave birth to significantly fewer boys (only 23.5% compared to the normal 51%), and male babies born to exposed mothers had lower birth weights. The study suggests that EMF exposure may selectively affect male reproductive outcomes.

Study Details

The aim of this case-referent study was to investigate reproductive hazards other than congenital malformations after exposure to high-frequency electromagnetic radiation.

Cases and referents were sampled from a cohort of pregnancies of members of the Union of Danish Phys...

A total of 8.4% did not participate. Only 23.5% of the children born by the highly exposed mothers w...

The other outcomes were not statistically significantly associated with exposure to high-frequency electromagnetic radiation.
