ELI5: When men get kicked in the balls, why does the pain elevate from their crotch to their lower stomach region?

When guys are in early fetal development their testes start off as ovaries. The nerves develop and connect to the spine just below the stomach. Then as the testes descend through the body the nerves extend with them. That's why it feels in the stomach when you get hit in them, its where they connect to the spine.
