Futanari (ふたなり, seldom: 二形, 双形, literally:
dual form; 二成, 双成, literally: "[to be of] two kinds") is the
Japanese word for
hermaphroditism, which is also used in a broader sense for
androgyny.
[1][2]: 79, 81
Beyond Japan, the term has come to be used to describe a
commonly pornographic genre of
eroge,
manga, and
anime, which includes characters that show primary sexual characteristics from both
females and
males.
[1] In today's language, it refers almost exclusively to characters who have an overall
feminine body, but have both female and male primary genitalia (although a
scrotum is not always present, while
breasts, a
penis, and a
vulva are). The term is also often abbreviated as
futa(s), which is also used as a generalized term for the works themselves.
