Magnetic field exposure was applied from day 1 to day 5.5 or from day 1 to day 7 of pregnancy. The preimplantation periode in mice, from fertilization until implantation of the embryo in the uterus, takes 5.5 days. All animals were sacrificed for examination on day 19, one day before birth.

As compared with sham control, no significant increase of early fetal death was observed in exposed animals. The lenght and body weight of living embryos was significantly decreased in animals exposed for 5.5 days. Progesterone and calcium levels in dames were not significantly altered due to magnetic field exposure, except on day 3 and day 13 when progesteron and calcium levels were found to be elevated in exposed dams, respectively.
