Some nematodes (round worms) exhibit androdioecy, a reproductive system characterized by the coexistence of males and hermaphrodites. Androdioecy is rare in comparison to the other major reproductive systems. In animals, androdioecy has been considered an important stepping stone in the transition from dioecy (separate males and females) to hermaphroditism, and vice versa.
