Testis and Ovaries

Definition

These are primary reproductive organs; testes in males produce sperm and testosterone while ovaries in females produce eggs (ova) and hormones such as estrogen and progesterone.

Analogy

Consider testis and ovaries as factories where essential products are made. In this case, these 'factories' manufacture sperm/eggs along with important hormones necessary for reproduction just like how toy factories would make toys along with packaging materials needed for their distribution.
