Definitions: Sex/Gender Identity/Transgender
Each of us has an assigned sex, a gender identity, and a sexual orientation.
The classification of people as male or female. At birth infants are assigned a sex, usually based on the appearance of their external anatomy. (This is what is written on the birth certificate.) However, a person’s sex is actually a combination of bodily characteristics including: chromosomes, hormones, internal and external reproductive organs, and secondary sex characteristics.
One’s internal, deeply held sense of one’s gender. For transgender people, their own internal gender identity does not match the sex they were assigned at birth. Most people have a gender identity of man or woman (or boy or girl). For some people, their gender identity does not fit neatly into one of those two choices. Unlike gender expression, gender identity is not visible to others.
External manifestations of gender, expressed through one’s name, pronouns, clothing, haircut, behavior, voice, or body characteristics. Society identifies these cues as masculine and feminine, although what is considered masculine and feminine changes over time and varies by culture. Typically, transgender people seek to make their gender expression align with their gender identity, rather than the sex they were assigned at birth.
An umbrella term for people whose gender identity and/or gender expression differs from what is typically associated with the sex they were assigned at birth. People under the transgender umbrella may describe themselves using one or more of a wide variety of terms – including transgender. Some of those terms are defined below. Use the descriptive term preferred by the individual. Many transgender people are prescribed hormones by their doctors to change their bodies. Some undergo surgery as well. But not all transgender people can or will take those steps, and a transgender identity is not dependent upon medical procedures.
People who were assigned female at birth but identify and live as a man may use this term to describe themselves. They may shorten it to trans man. (Note: trans man, not "transman.") Some may also use FTM, an abbreviation for female-to-male. Some may prefer to simply be called men, without any modifier. It is best to ask which term an individual prefers.
