condition in which characteristics of both sexes are clearly expressed in a single individual. In biology, androgyny refers to individuals with fully developed sexual organs of both sexes, also called hermaphrodites. Body build and other physical characteristics of these individuals are a blend of normal male and female features.

In psychology, androgyny refers to individuals with strong personality traits associated with both sexes, combining toughness and gentleness, assertiveness and nurturing behaviour, as called for by the situation. Androgynous individuals are more likely to engage in cross-sexual behaviour than those who maintain traditional sex roles. The rise of feminism and the influence of the women's rights movement made certain aspects of androgynous behaviour more socially attractive than in the past. Androgynous figures occurred frequently in Greek mythology, often embodying a blend of desirable male and female characteristics. The blind seer Tiresias, a figure of great wisdom, was sometimes depicted as a hermaphrodite.
