It's also possible, in a roundabout way, that external testicles are more for display rather than practicality. Sexual selection has a fairly heavy weight on evolution, even if such a trait has some pretty big downsides (male peacocks being a prime example of this).
- beaconstudios 8y agoThat would make total sense if the human mating ritual involved the male impressing the female with the size of his testicles.

Culture changes faster than evolution. http://mentalfloss.com/article/79897/why-arent-classical-statues-very-well-endowed http://mentalfloss.com/article/79897/why-arent-classical-sta... “Ancient Greece was a highly masculinist culture,” she explained. “They favored ‘small and taut’ genitals, as opposed to big sex organs, to show male self-control in matters of sexuality."
- beaconstudios 8y agoexactly, most of culture changes fast and for there to be a sexually selective pressure on testicles for a long enough time to make a difference, it would surely persist into recorded history. Either human mating practices are cultural and transitive so they would not exert continuous evolutionary pressure, or they are somehow more ingrained and thus could exist long enough to trigger noticeable evolutionary changes.
