Testosterone esters were synthesized for the first time in 1936, and were found to have greatly improved potency relative to testosterone. [11] Among the esters synthesized, testosterone propionate was the most potent, and for this reason, was selected for further development, subsequently being marketed. [11] Testosterone propionate was introduced in 1937 by Schering AG in Germany under the brand name Testoviron. [8] It was the first ester of testosterone to be introduced, [12] and was the major form of testosterone used medically before 1960. [8] In the 1950s, longer-acting testosterone esters like testosterone enanthate and testosterone cypionate were introduced and superseded testosterone propionate. [12] Although rarely used nowadays due to its short duration, [13] testosterone propionate remains medically available. [8]

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]
