ELI5: why does it hurt when you get hit in the testicles?
gpt
Basically, when you're in your mother's womb, your testicles start up near your stomach. Your nerves grow into your testicles as if they are a deep internal abdominal organ....then they descend into your scrotum.

So that's why when you get kicked in the balls, it feels like you're getting punched in the stomach at the same time. Everything is all cross-wired.
