In biology, a hermaphrodite is an organism that has reproductive organs normally associated with both male and female sexes.
Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which both partners can act as the "female" or "male". For example, the great majority of pulmonate snails, opisthobranch snails and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites.
Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings, The word hermaphrodite entered the English lexicon in the 15th century, derived from the Greek Hermaphroditos a combination of the names of the gods Hermes (male) and Aphrodite (female). Recently, the word "intersex" has come into use for humans, since the word "hermaphrodite" is considered by a few over-sensitive people to be misleading and stigmatizing.
