Why do human testicles hang like that?

An extremely interesting biological question, wouldn't you think? Given that the testicles contain possibly the most important ingredient for the continued survival of the human race, their placement (come consider it outside the body proper) surely raises a few eyebrows as to why.

Well, ponder no more, as Scientific American provides an interesting hypothesis as to why the testicles are designed to hang low.

Now, sperm is best kept at a temperature of 34 degrees Celsius. But we all know our body temperature hover at around 37, hence, storing them anywhere within the body is just not gonna be good enough. So, a thin scrotum, and scrotal descent seems the best way to go about it. Now, not only is the scrotal sack descended, it also regulates its temperature at every single moment.

Think back to the last time you had a cold shower... yeah, they retract, don't they? This is because the temperature is too cold, and they retract close to the body to gain some of the warmth. And if you were to think of that awesome hotspring bath you had in Japan, and if you happened to look down and admire the package, you would notice that it hangs lower and more relaxed, in an effort to try and dissipate more heat.

And this, my friends, is the reason why we should not wear those tight briefs anymore, no matter what Freddie Lundberg would have you believe.

Lastly, to compensate for the extremely vulnerable position our jewels are in, our testicles' threshold of pain is superbly low, allowing us to detect and sense any threat 50m away.
