The hydrolisis of dehydroepiandrosterone sulfate added to human urine was studied under several hydrolytic procedures. Enzymatic and acid hydrolysis with and without the previous removal of enzymic inhibitors present in the human urine were compared. The simple precipitation of inorganic ions with barium acetate before the enzymatic hydrolysis was considered an efficient procedure giving an 81% recovery of the added dehydroepiandrosterone. Since this procedure does not involve rearrangements in the steroid molecules, and because of its simplicity it is considered adequate for the determination of the urinary steroid excretion patterns in humans allowing the quantitation of some conjugates (16 alpha-hydroxy-dehydroepiandrosterone) otherwise not detectable because of its incomplete hydrolysis and extraction.

The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression". [77] [78] Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible. [77] The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game. [79] Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males. [80] [81] [82] [83] [84]
