> Given the evolutionarily vital role of the ol’ nugs, how long will it take for the human species to evolve a sort of built-in cup, like a skull for your balls? Does any other species have this? Or maybe the quicker path will be for the testes to move back into the abdomen where they’ll be protected like all the other vital organs. I know they hang outside the body for temperature control, but it’s an awful tradeoff. Maybe in a million years or so they can stay snug up against the kidneys but with their processes altered such that they can still produce sperm at the higher temperature.

Well, in some animal species, the inguinal ring (the connective tissue that prevents testes from going back to the abdominal cavity) is open/less restrictive than in humans. So these furry critters can pull their testes inside.

Makes castrating rabbits (for example) a bit difficult! 😉

And testes already have muscles that can pull them closer to the body (but not inside). They’re useful in animals when it gets too cold outside.
