In this 21st. Century, a century whereby the evolution of the Human Race has come to an unprecedented level - a level where space travel, Internet, computer systems, robots, even virtual warfare have developed due to mankind's brilliance in technologies - the world of medicine, also, has become transformed by medical advances that have been outside of the creativity of even though some of the most outstanding scientists of only twenty five years ago.  
Medical care is lavished on the first detection of cancers, cardiovascular disorders, stroke and many other life threatening diseases, and thousands upon a huge number of books have been written as well as published on these very significant subjects - how you can look after the heart of yours, how to look after your blood pressure, exactly how to look after the body of yours in general and thereby avoid medical issues and diseases later in life.  
Yet the strangest, inexplicable and curious most omission from these' How to...' manuals is arguably by far the most essential contributions that male might ever produce to all areas of the Human Race -' How to Manage your Testicles'. Look at it this way - to an alien landing on our green world originating from a far galaxy, on examination of the Male of the predominant species, Mankind, the testicles would undoubtedly make the very least impression - hidden behind the penis, not appealing to look at, powerful-smelling if they are not cleaned regularly, without any apparent regulation from the brain; although on deeper examination, E.T. would definitely appreciate the primary function of these little orbs - the producers of the precise spark of reproduction of the human species, the spermatozoa, the initiator of Human Life on Earth, when conjoined with the egg of the female.  
But these organs get a further reason for being, running a good second to the sperm; the production of a chemical that gives the male of the species substantial physical power, concentrated psychological focus and power, immunity to disease as well as - vitally important - the desire to have sex along with the ability to perform the action of mating, and therefore the assurance of prolongation of the species.  
And also to be able to achieve this action of mating, confident and strong erection of the penis is essential. What is this magic substance that these 2, unloved, uncared for and pretty much forgotten little balls work 24/7 to produce?  
Testosterone. The sex hormone which makes a male have' man' functions, which makes the male body look' male'. Testosterone, known as' The King of the Hormones' is one of the key, click here [official statement] the substances that provides man the sex drive to want to mate, have sex, and do it very well. It can be this hormone that offers muscle mass bulk as well as muscular strength, strong bones as well as immunity to disease.  
Additionally, testosterone is among the primary key elements in elevating mental concentration as well as the alertness quantities which made our early ancestors crafty, cunning, effective hunters of prey larger and more powerful than them. Really a wonder drug.  
So just how can it perhaps be that religions of all types, governments, the healthcare world and human society in general, ignore - or perhaps worse still - ridicule these two very important components of the evolution as well as continuation of the human race?
