Fetal hyperthermia

Temperature changes. Another common gestational problem is high maternal body temperature that translates into high fetal temperature. Fetal hyperthermia can result in severe consequences anencephaly, spina bifida, mental retardation, facial defects, cardiac abnormalities, and limb defects—all classical clinical abnormalities.23... 

Hyperthermia induced by an elevation in ambient temperature following RF radiation is known to be associated with fetal developmental effects. 2-Methoxyethanol is a known teratogen. In a study on laboratory animals it was demonstrated that combined exposure to RF and 2-methoxyethanol enhanced the adverse effects produced by either agent alone. It was also noted that teratogenic effects of 2-methoxyethanol were observed at levels below those found for the solvent alone, when it was co-administered with RFJ251...
