Buccal smears from 147 fullterm newborns have been studied. Twenty-nine newborns who had negative sex chromatin, were male infants. Hundred and eighteen newborns with sex chnomatin positive were females showing a lower incidence than previously reported. The peak value was on the 3rd day of life and lowered thereafter.
