Androgyny
Androgyny is the possession of both masculine and feminine characteristics. Androgyny may be expressed with regard to biological sex, gender identity, or gender expression.
When androgyny refers to mixed biological sex characteristics in humans, it often refers to intersex people, who are born with congenital variations that complicate assigning their sex at birth. In comparison, hermaphroditism is the possession of both male and female reproductive organs.
Regarding gender identity, androgynous individuals may identify as transgender or non-binary and use this as a form of gender expression, in which androgyny has fluctuated in popularity in different cultures and throughout history. Physically, an androgynous appearance may be achieved through personal grooming, fashion, or hormone treatment.
Androgyny in those who are assigned female at birth is suggested to contribute to positive mental health, although individual factors such as education and marital status may affect this.
