I'm sure that in the middle of the night you have contemplated the thorny problem of why the body's most sensitive organ, the testicles, are outside the protective carapace of the male chassis? Anyone who has received a football to the bollocks will testify to evolution's folly for not contemplating internal stowage. Only a mature male can experience the nagging, dragging, agonising pain that will inevitably transpire following contact with a hard unyielding object; transsexuals, take note. Upon impact there is the inevitable two second delay as the neural signal travels from the organ of contact/impact to the brain. The finale is a paroxysmal wave of agony experienced by the soma, (O deep joy). You might conclude that males would be better served by sequestering these sensitive glands deep inside the body cavity. The fact that this profoundly delicate male organ swings unfettered and free, awaiting the exquisite vicissitudes of life's slings and arrows, seems but a cruel joke of biology. Indeed, tis the most cogent argument for an omniscient, omnipotent, omnipresent deity being of the female persuasion.
The testicles are enclosed in their own 'protective', yielding bag of skin. The rugeform and elastic scrotum encapsulates this valuable organic package and keeps it sequestered from the somatic mass of the main organism. It is has not gone without notice that the scrotal sac waxes and wains according to the ambient temperature. Its inherent properties of malleability, pliability, extensibility and thermal compliance are responsible for the propensity for extreme contraction and augmentation.
The relationship between temperature and scrotal volume has been exhaustively researched, by myself, during a time when I eschewed medication. This involved placing said sac in water of varying thermal content. Fortuitously, the water itself also serves as a measure of volume due to the ancient principle of Archimedean water displacement. Overflow was conveniently collected in a strategically placed scientific grade measuring cylinder. The result confuted and confounded expectations, and belied simple analysis. And thus, it transpired that the correlation was not an equal, direct, correspondent, comparable, proportionate relationship. To my chagrin and vexation, my data revealed a binomial, sigmoidal relationship. This is counter to intuitive expectations. However, on reflection and further research, the result was found to be in perfect accord with the general properties of elastic materials as illustrated by Charles Law.
Science Stuff
After the above preamble tis pertinent to address the fundamental question/quest as stated, cogently and with veritable aplomb, in the first paragraph of this esteemed post.
Testicles have two main roles in the physiology of mammals. Firstly, they are responsible for the male hormone, testosterone, that defines masculinity, in all its manifold aspects. Formation and excretion of testosterone is not exclusive to the male gender and lesser amounts are secreted by the female of the species (don't ask). Secondly, the testes are the seat of sperm production. The development of male spermatozoa is a complex and interesting topic in itself. The average healthy male 'manufactures' 50-200 million spermatozoa per day and the average ejaculate contains, on average, 7 billion of the little, wriggling buggers.
In my professional capacity as a geneticist I have had the privilege to research and develop a diagnostic laboratory technique for sperm analysis. Specifically, the methodology was aimed at detecting genetically abnormal spermatozoa in the ejaculate of men carrying a known genetic anomaly. I posted a whimsical side swipe of the experience, here: The Flaxen Saxon Chronicles: Search results for consummate professional
My interest in matters 'Scrotal' is not confined to my professional proclivities. Indeed, I'm an esteemed inventor of note and have used my talents, as an innovator, to combine my prodigious practical proficiency with my passion for the science of Bollockology, to engineer a mechanical device for the measurement of scrotal movement following a thermal insult. The Scrotometer (pat pending) and its practical deployment can be accessed using the following link: The Flaxen Saxon Chronicles: Search results for scrotometer
