animal testicles are eaten globally, most famously as "Rocky Mountain Oysters" (bulls), but also from lambs, pigs, turkeys, goats, deer, bison, and even birds like ducks and ostriches, prepared fried, grilled, or roasted, often under euphemistic names as a delicacy or traditional food. These are typically from young castrated males, a byproduct of meat production, offering a mild taste similar to calamari or chicken when cooked.
