adj form of cisgender
The opposite of transgendered, someone who is cisgendered has a gender identity
that agrees with their societally recognized sex
Many transgender people prefer "cisgender" to "biological", "genetic", or "real" male or female because of the implications of those words. Using the term "biological female" or "genetic female" to describe cisgendered individuals excludes transgendered men, who also fit that description. To call a cisgendered woman a "real woman" is exclusive of transwomen, who are considered within their communities to be "real" women, also.
Some of my friends are trans, but I'm cisgendered.
