REMARKS ON THE PROBLEM OF AGE DETERMINATION IN FETUSES AND NEWBORNS. The
determination of the exact moment of conception is burdened with an error, and; the moment of birth does not
indicate to the same degree of development of the newborns. These facts as well as the specificity of the material
on which the investigation of fetal growth is based result in numerous methodological problems in research on
ontogenesis of the prenatal period.
