Cisgender (often abbreviated to simply
cis) describes related types of
gender identity perceptions, where individuals' experiences of their own
gender agree with the
sex they were
assigned at birth. Sociologists Kristen Schilt and Laurel Westbrook define
cisgender as a label for "individuals who have a match between the gender they were assigned at birth, their bodies, and their personal identity". They see
cisgender as a complement to
transgender.
