The paper contains a critical review of the available literature on the subject of the effects of developing animals from exposure to pulsed magnetic fields (PMF). The workshop at which the presentation was originally made discussed the reproductive effects in women from the use of video display terminals. Apparently, exposure of embryonic animal models (chick embryo, fish embryo, rat and mouse embryos) in PMF may result in statistically significant increases in detrimental effects. The appearance of the effect (usually, increased abnormality rates) is not clearly relatable to pulse frequency, pulse shape, or field intensity.
