         We determined the urinary excretion of androsterone, pregnanediol, pregnanetriol,
            estron, estradiol and estriol by gas-liquid chromatography or by fluorometry. The
            values are given in accordance to the bone age of the girls. There was not only an
            increase in the total steroid excretion but also changes in the relationship of the
            steroids one to another.
