Testosterone level in male

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]

While it has become increasingly common for testosterone therapy to be used by many men who suffer from low levels the most common reason anyone uses testosterone is for performance enhancing. Again, this is an instance where the desire is to increase testosterone levels far beyond a normal range in order to reach and often surpass a desired goal. For this individual a much higher dose of testosterone will need to be administered and normally on a more frequent basis. While there are many forms of testosterone applications for the performance enhancer injectable remedies will be the ones used most due to their higher levels of efficiency. Although administration will typically be injectable there are several forms of testosterone in-which you may choose from and all are acceptable; they most commonly include:
