Methods
Endpoint/Measurement parameters/Methodology

• effects on embryo/fetus: body weight, skeletal variations
• effects on reproductive system: number of implementation sites and living fetuses per litter

investigated material: femal rats and embryos

time of investigation: after exposure

Comment on methods (up to 2000 characters):

Main outcome of study (according to author)
No adverse effects of exposure were observed in dams. In the 50 Hz group the mean number of implantations and living fetuses per litter were statistically significant increased. In bothe groups the incidence of fetuses with minor skeletal anomalies were statistically significant increased.
