Loin

The loins are between the lower ribs and pelvis. It is often used when describing the anatomy of humans and quadrupeds (such as horses, pigs or cattle). The anatomical reference also carries over into the description of cuts of meat from some such animals, eg. tenderloin or sirloin steak.

The term also loosely refers to human genitals due to their prominence in that anatomical region. Hence "fruit of one's loins" means children.
