DHT is a potent agonist of the AR, and is in fact the most potent known endogenous ligand of the receptor. It has an affinity (K d ) of to  nM for the human AR, which is about 2- to 3-fold higher than that of testosterone (K d = to  nM) [43] and 15–30 times higher than that of adrenal androgens . [44] In addition, the dissociation rate of DHT from the AR is 5-fold slower than that of testosterone. [45] The EC 50 of DHT for activation of the AR is  nM, which is about 5-fold stronger than that of testosterone (EC 50 =  nM). [46] In bioassays , DHT has been found to be - to 10-fold more potent than testosterone. [43]

The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression". [79] [80] 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. [79] 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. [81] Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males. [82] [83] [84] [85] [86]

A survey of 28,000 users found that many Italian males started an "excessive consumption" of porn sites as early as 14 years old. After daily use in their early to mid-20s, they become inured to "even the most violent" images. The effects of developing their sexuality largely divorced from real-life relationships are gradual and devastating. "It starts with lower reactions to porn sites, then there is a general drop in libido and in the end it becomes impossible to get an erection," Carlo Foresta, head of the Italian Society of Andrology and Sexual Medicine (SIAMS), told reporters. However, the condition is not irreversible and a proper recovery is possible within just a few short months.

ATHLETES:   Overtraining can seriously affect performance.  Researchers have identified several short term key markers that result from overtraining, including "impaired anaerobic lactic acid perforance and a reduced time to exhaustion". [ 7 ] The same study discusses many other soon-to-follow issues including problems with uric acid levels, ammonia, creatine kinase, free testosterone/cortisol, growth hormone and so on. More subjective issues include excessively sore muscles and sleep and mood disorders.  Again, overtraining is real and leads to real physiological issues.
