Abstract

The safety of human exposure to an ever-increasing number and diversity of electromagnetic field (EMF) sources both at work and at home has become a public health issue. To date, many in vivo and in vitro studies have revealed that EMF exposure can alter cellular homeostasis, endocrine function, reproductive function, and fetal development in animal systems. Reproductive parameters reported to be altered by EMF exposure include male germ cell death, the estrous cycle, reproductive endocrine hormones, reproductive organ weights, sperm motility, early embryonic development, and pregnancy success. At the cellular level, an increase in free radicals and [Ca(2+)]i may mediate the effect of EMFs and lead to cell growth inhibition, protein misfolding, and DNA breaks. The effect of EMF exposure on reproductive function differs according to frequency and wave, strength (energy), and duration of exposure. In the present review, the effects of EMFs on reproductive function are summarized according to the types of EMF, wave type, strength, and duration of exposure at cellular and organism levels.

Main findings

This review summarizes in vivo and in vitro evidence (primarily in animal systems) reporting that EMF exposure can alter cellular homeostasis, endocrine and reproductive function, and fetal development. Reported altered reproductive parameters include male germ cell death, estrous cycle changes, hormone changes, organ weight changes, reduced sperm motility, effects on early embryonic development, and pregnancy success; proposed cellular mediators include increased free radicals and intracellular Ca2+ leading to growth inhibition, protein misfolding, and DNA breaks. The review notes that effects differ by frequency/wave type, strength (energy), and duration of exposure.
