48 pregnant mice were divided into six groups (each group n=8): 1) control group, 2) sham exposed group, 3) - 6) exposure groups starting with exposure on different days of gestation (1-5, 6-10, 11-15, 16-20).
Exposure duration: continuous for 10 h/day on 5 days
Mice were divided into six groups: i) control ii) sham exposure iii) five days of EMF exposure starting on day 1 of gestation iv) five days of EMF exposure starting on day 6 of gestation v) five days of EMF exposure starting on day 11 of gestation vi) five days of EMF exposure starting on day 16 of gestation
|Sham exposure||A sham exposure was conducted.|
|Additional info||it can not be extracted from the article which sort of coil was used: a Helmholtz coil or a solenoid; the authors mention a Helmholtz coil but describes a solenoid (a 50 Hz sinusoidal oscillating ELF-EMF was produced by a 380 round turn coil twisted around a cylinder - 19 cm diameter and 15.5 cm length - and containing a chamber to house mice in the center of the cylinder)|

Total body weight of newborns, the volume of spleen, and the number of megakaryocytes decreased following the exposure to extremely low frequency electromagnetic fields. The complete period of gestation was sensitive to exposure and the initial days were more sensitive, i.e. the effects were more pronounced.
