Science for Litizens
Quote:
In many respects, the activation hypothesis serves to elaborate what many of us already know about descended scrotal testicles: that they serve as a sort of “ cold storage” and production unit for sperm, which keep best at lower body temperatures. But it goes much further than this fact, too. It turns out that human testicles display some rather elaborate yet subtle temperature-regulating features that have gone largely unnoticed by doctors, researchers and laymen alike. The main tenet of the activation hypothesis is that the heat of a woman's vagina radically jumpstarts sperm that have been hibernating in the cool, airy scrotal sack. Yet it explains many other things too, including why one testicle is usually slightly lower than the other, why the skin of the scrotum becomes more taut and the testicles retract during sexual arousal, and even why testicular injuries--compared to other types of bodily assault--are so excruciatingly painful to men.
...
There are many other ancillary hypotheses connected to the activation hypothesis as well. For example, the authors ponder whether humans’ well-documented preference--and one rather unique in the animal kingdom--for nighttime sex can be at least partially explained by temperature-sensitive testicles. Although the authors note the many benefits of nocturnal copulation (such as accommodating clandestine sex or minimizing the threat of predation), this preference may also reflect a circadian adaptation related to descended scrota. Given that our species evolved originally in equatorial regions where daytime temperatures often soared above body temperature, optimal testicular adjustments would be difficult to maintain in such excessive heat. In contrast, ambient temperatures during the evening and at night fall below body temperature, returning to ideal thermoregulatory conditions for the testes. Additionally, after nighttime sex the woman is likely to sleep, thus remaining in a stationary, often supine position that also maximizes the odds of fertilization.

What does relevance have to do with Lit?
For that matter, when it comes to the political Science of the day what does truth have to do with Scientific American? |

I didn't say Lit, I said anything.

That's not saying a lot.
You know that, right?
P.S. ... has your so-called "mate" realized that he doesn't really know you, yet?

Cole Porter explained all that years ago.
"According to the Kinsey report
ev'ry average man you know
much prefers to play his favorite sport
when the temperature is low
but when the thermometer goes way up
and the weather is sizzling hot
Mister Adam for his madam is not
cause it's too too
it's too darn hot, it's too darn hot
It's too too too too darn hot
I'd like to call on my baby tongiht
and give my all to my baby tonight
I'd like to call on my baby tongiht
and give my all to my baby tonight
but I can't play ball with my baby tonight
cause it's too darn hot
it's too darn hot"
