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]

Testosterone enanthate ( USAN , BAN ) (brand names Delatestryl , Testostroval , Testro LA , Andro LA , Durathate , Everone , Testrin , Andropository ), or testosterone heptanoate , is an androgen and anabolic steroid and a testosterone ester . [2] [3] [4] Along with testosterone cypionate and testosterone propionate , it is one of the most widely used testosterone esters. [5] Testosterone enanthate was first introduced in 1952. [6] Administered via intramuscular injection , it is the most widely used form of testosterone in androgen replacement therapy . [6]

Other significant adverse effects of testosterone supplementation include acceleration of pre-existing prostate cancer growth in individuals who have undergone androgen deprivation; increased hematocrit , which can require venipuncture in order to treat; and, exacerbation of sleep apnea . [24] Adverse effects may also include minor side-effects such as acne and oily skin, as well as, significant hair loss and/or thinning of the hair, which may be prevented with 5-alpha reductase inhibitors ordinarily used for the treatment of benign prostatic hyperplasia , such as finasteride . [25] Exogenous testosterone may also cause suppression of spermatogenesis , leading to, in some cases, infertility. [26] It is recommended that physicians screen for prostate cancer with a digital rectal exam and prostate-specific antigen (PSA) level before starting therapy, and monitor PSA and hematocrit levels closely during therapy.
