What causes testosterone deficiency

“This whole subject is very contentious - mainly because there's a lot of money in convincing people they have a low testosterone, and then selling it to them” says Dr David Delvin, GP and family planning adviser. “In the Harley Street area, there are thriving private practices and clinics which make a fat living out of doing just that. In 40 years of medical practice --much of it involving sexual medicine -- I have seen less than a dozen men who genuinely had a low testosterone, and I can't recall seeing any women who had a low testosterone level (except after gland surgery). I suspect the average GP would fall about laughing if you asked whether fatigue was likely to be due to testosterone deficiency.

When testosterone levels in a man become low, he may start to experience various unpleasant symptoms, since this hormone is responsible for the maintenance of several functions in his body. Learning what the symptoms are, what causes the condition and how it can be treated helps men identify the signs of low T early on; thus ensuring* their condition can be treated quickly and more successfully, since a late diagnosis might mean the man will need a considerable amount of testosterone therapy to produce effective results when trying to restore his testosterone levels.

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]

The Tamil movie Kumki , which revolves around a mahout and his trained elephant, shows his elephant in musth period towards the climax. Captive elephants are either trained for duties in temples (and in cultural festivals), or trained as a Kumki elephant which confronts wild elephants and prevents them from entering into tribal villages. Elephants trained for temple duties are of a gentle nature and cannot face wild elephants. In this movie, a tribal village wants to hire a Kumki elephant to chase away wild elephants which enter the village every harvest season. The mahout, who is in want of money, takes his temple-trained elephant to do this job, in the vain hope that wild elephants won't come in. But wild elephants start attacking the village on the harvest day. The temple-trained elephant gets into musth and thus fights with the wild elephants, kills the most notorious among the herd, and gets killed because of injuries sustained during the fight.
