The Interboth flag.

Interboth or Interduo is an exclusive gender for intersex individuals who identify simultaneously as both a woman and a man, or fluid between the two, in a uniquely intersex-way. They may feel as though they have an altered form of a woman and a man, or they may just wish to embrace the intersex part of their identity, despite feeling little to no connection to it.

To be interboth, one does not to have been assigned X at birth or unassigned at birth, or have androgynous sex traits. Instead, they simply have to identify as a man and a woman in some shape or form, regardless of whether or not they have biological androgynous/neutral characteristics.

If someone identifying as interboth has biological androgynous traits, they may also identify as cisgender, however they do not have to if they feel cis does not match their experiences.

They may or may not be fluid or fluctuate between man-related and woman-related identities, or (more specifically) intersex-related man-related/woman-related identities (such as intergirl and/or interboy.)

This term was coined as many intersex individuals have a unique experience with androgyny/neutrality, due to their sex. This could overlap with being intergender, or another intersex-exclusive gender.

This term falls under the Inter-System, where other similar genders and counterparts are listed.
