It was demonstrated in investigations performed in 44 newborn girls, that the glucose 6 phosphate dehydrogenase activity of the erythrocytes gradually decreases up to the 7th day of life. This process goes hand in hand with the increase of sex chromatin, i.e. of heterochromatic chromosomes. These phenomena can be indirectly ascribed to the estrogens. No similar changes in enzyme activity were found in 28 newborn boys investigated as controls.
