Hermaphrodite, an organism that has both male and female reproductive organs. For some species, hermaphroditism is normal. Hermaphroditic plants have both pistils (female sex organs) and stamens (male sex organs) in a single flower. Such animals as flatworms and certain species of segmented worms, mollusks, crustaceans, and fish are hermaphroditic; each individual can produce both eggs and sperm. Hermaphroditism sometimes occurs in individuals of a species whose members normally have only male or only female sex organs. A human baby can be born with both ovaries and testes, but in most cases neither reproductive system is complete.
