The term “transgender” refers to a person whose sex assigned at birth (i.e. the sex assigned by a physician at birth, usually based on external genitalia) does not match their gender identity (i.e., one’s psychological sense of their gender). Some people who are transgender will experience “gender dysphoria,” which refers to psychological distress that results from an incongruence between one’s sex assigned at birth and one’s gender identity. Though gender dysphoria often begins in childhood, some people may not experience it until after puberty or much later.
People who are transgender may pursue multiple domains of gender affirmation, including social affirmation (e.g., changing one’s name and pronouns), legal affirmation (e.g., changing gender markers on one’s government-issued documents), medical affirmation (e.g., pubertal suppression or gender-affirming hormones), and/or surgical affirmation (e.g., vaginoplasty, facial feminization surgery, breast augmentation, masculine chest reconstruction, etc.). Of note, not all people who are transgender will desire all domains of gender affirmation, as these are highly personal and individual decisions.
