AI Overview
A cis man is a man whose gender identity aligns with the sex assigned to him at birth. The term “cisgender” (or “cis”) is a prefix meaning “on the same side,” contrasting with “transgender” (trans), which describes someone whose gender identity differs from their sex assigned at birth. Most people are cisgender, and for cis men, being a man is their authentic identity and also the gender they were assumed to be as a baby.
Key Points
Gender Identity vs. Assigned Sex:
A cis man’s internal sense of self (gender identity) as a man matches the sex assigned at birth.
Origin of the Term:
The prefix “cis” comes from the Latin word for “same,” mirroring the term “trans” (meaning “across”) used in chemistry and biology.
Purpose of the Term:
“Cisgender” provides a neutral and specific term to describe people whose gender aligns with their assigned sex at birth, avoiding the implication that trans people are “abnormal” or “irregular”.
Commonality:
The vast majority of people are cisgender, and many cisgender people may not think of themselves this way because their gender identity is so commonly understood and accepted.
