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.
