This general topic needs to be approached from a very broad perspective, and is relevant to what I have discovered
It appears that the majority of the pro androgenic elements have been entirely removed from the human environment. Testosterone building herbs, roots, and uncastrated male animal have been eliminated and replaced entirely with estrogen dominant foodstuffs. While at the same time artificial estrogen chemicals have saturated the terrestrial environment.
Other complications stemming from lack of certain nutrients, and deficiency of natural sunlight also play a role. Testosterone is built upon a foundation of cholesterol and the D proto-vitamins which are best synthesized by UV harnessing probiotic microbes and absorbed in the skin. Also testosterone cannot be properly broken down if the liver is overloaded with the toxic byproducts of poor food stuffs, estrogen mimickers, and whatever ungodly substances the kids are eating these days. These unproperly metabolized hormonal waste is eliminated through the skin where iot triggers oil glands to produce extra oil while stimulating bacterial detoxification protocol, as a means to void thorough the pores. The resulting Acne outbreaks are acutually a form of detoxification in accord with the Theory of AV regarding bacterial detox.
Sun Bathing along with practicing natural hygiene, and eliminating the triggering foods is the best way to begin to deal these kind of issues. The skin excretes oily substances laced with a food for certain bacteria, these bacteria intern detoxify the skin while producing vitamin D from UV light. This is a delicate process and is easily disrupted by using cleansers, other cosmetic products, antibiotics, sun avoidance, and in part leads people to become unable to obtain optimal hormonal balance.
This is a bit of a tangent, but one worth following...Our hormonal systems not only regular our own bodies functions, but also on a Phenomenal level they trigger responses in others who share the same environment. I believe the bacteria which we cultivate on our skin send signals which can give valuable information about who we are, what our condition is on many levels...but because of the hive like conditions many modern humans live in, these pheromones have created sensory overload, where peoples natural biological aversions and attractions become disruptive to the social hierarchies of the business space, and so have been forcibly repressed, by the strict enforcement of dermal sterilization rituals.
Males particularly because they have a stronger natural scent, but also females are forced to use deodorizing chemicals at the start of puberty, and so most people grow up with the impression that Men are suppose to smell like cheap cologne and antiseptics, and the women to smell like fake flowers and perfume. Women are also forced to shave their pit and body hair which originally evolved to act like atomizers to spread their pheromones through the air. People who grow up entirely sheltered from phenomenal influences, do not develop proper sensitivities to the biological cues present in these hormonal messages, and so many are screwed up and mixed up when it comes to establishing organically evolving relationships.
Such confusion and disassociation with our biological hormonal cues, enable the development of structural dominance hierarchies, which do not operate in accord to humanities innate biological imperatives. Humans did not evolve to be A-sexual hive insects, yet these social hierarchical structures necessary for advanced societal cohesion seem to encourage trends of lower overall testosterone levels along with the suppression of healthy gender expressions in both men and women.
Where did these trends begin, could it be that agricultural societies began to cultivate emasculation foods, which took the wild out of humans who would otherwise not be content to live within such limited boundaries. Wild people who continued to forage and consume androgenic foods were eventually out bred and replaced by the exponentially increasing agricultural populations. The nomadic tribes one by one over the last 12,000 years began to become subjugated to effects the cooked estrogen. The yam, the soybean, the nightshades and many varieties of plants developed estrogen like chemicals as a biological defense mechanism, which were intended to render over consumers vapid and impotent...yet through the development of cooking humans began to tolerate higher and higher levels of these hormone mimickers, up to the point where tolerance led to addiction, so that those most effected by hormone disruption actually prefer the emasculated life, and are even collectively triggered by any expression of hyper masculinity traits in others.
