The rate of the total urinary 17-ketosteroids has been studied in twins of the two sexes (8 ♂ ♂ and 3 ♀ ♀ MZ, and 4 ♂ ♂ and 3 ♀ ♀ DZ, for a total of 18 twin pairs).

On the basis of this material it could be shown: (i) that the metabolism of the urinary 17-ketosteroids is genetically controlled for a quantum of 43.65%; (ii) that the secretion of the urinary 17-ketosteroids is correlated with age, and (iii) that a quantitative differentiation of the phenomenon exists in the two sexes.
