To expound: body temp is too high for sperm, hence the whole scrotum shebang. If it's cold, and the testicles require a raise in temperature, the scrotum shrinks a bit and moves further towards the body in order for body heat to raise its temp. Vice versa when it's warm.
I really don’t understand how putting a sensitive internal organ on the outside of the body to better control temperature was the easier path than sperm that can tolerate being like 2 degrees warmer
Oh yeah once it happened I understand why it stayed. But sperm producing organs started inside, so I would’ve expected slight preferences for temperature by sperm would be easier to change than moving an organ outside.
retractable balls is the norm. I remember there was this porn guy whose balls just sagged when performing, and when they shot closeups, he would have to use his hands to move his sagging balls out of the way so they can get a clear shot of the penetration lol
balls change depending on a lot of things, particularly temperature and arousal :PIGPOOPBALLS:

If you stare at them long enough you can even watch them go up and down.

Or make men run at lower temperature.

It was just the first solution to be good enough

They probably moved outside when we evolved from cold-blooded to warm-blooded, and body heat was too much for the current design.
