Glossary of Transgender Terms

Terms of Identity

Assigned sex at birth: The sex (male or female) assigned to a child at birth, most often based on the child’s external anatomy. Also referred to as birth sex, natal sex, biological sex or sex.

Cisgender: A term for people whose gender identity generally matches the gender assigned for their physical sex. In other words, someone who does not identify as transgender. The word is derived from the Latin root “cis” meaning “on this side.”

FTM: Female-to-male transgender person. Sometimes identifies as a transgender man. Someone assigned the female gender at birth who identifies on the male spectrum.

Genderqueer and/or nonbinary: People whose gender identity and/or gender expression falls outside the binary categories of man and woman. They may define their gender as falling somewhere in between man and woman, or they may define it as wholly different from these terms.

Gender affirming: Adjective used to refer to behaviors or interventions that affirm a transgender person’s gender identity (e.g., a physician using cross-sex hormones for a transgender patient may be called gender affirming, as can the use of a correctly gendered pronoun.)

MTF: Male-to-female transgender person. Sometimes known as a transgender woman. Someone assigned the male gender at birth who identifies on the female spectrum.

Transgender: An umbrella term for people whose gender identity does not match the sex they were assigned at birth. Transgender people may identify as straight, gay, bisexual or some other sexual orientation.

Transition: An individualized process in which transgender people move from living aligned with the sex they were assigned at birth to living aligned with their gender identity. There are three general aspects to transitioning: social (e.g., presentation, relationships, employment, names/pronouns); medical (e.g., hormones, surgery, mental health) and legal (e.g., changing gender marker and name on legal documents and identification). Each person’s transition path is unique.

Gender Affirming Medical Interventions

Bottom surgery: Colloquial phrase to describe gender affirming genital surgery.

Breast augmentation: Enlarging the breasts using breast implants.

Chest masculinization: A bilateral mastectomy that removes most of the breast tissue, shapes a contoured male chest, and refines the nipples and areolas.

Facial feminization surgery: Includes such procedures as reshaping the nose, and brow or forehead lift; reshaping of the chin, cheek and jaw; Adam’s apple reduction; lip augmentation; hairline restoration and earlobe reduction.

Facial masculinization surgery: Includes forehead lengthening and augmentation; cheek augmentation, reshaping the nose and chin; jaw augmentation; thyroid cartilage enhancement to construct an Adam’s apple.

Hormone replacement therapy (HRT): The process in which transgender people choose to take a prescription of synthetic hormones. For transgender women, that may include estrogen as well as testosterone blockers. For transgender men: testosterone (T).

Metoidioplasty: A surgical procedure that works with existing genital tissue to form a phallus, or new penis. It can be performed on anyone with significant clitoral growth caused by using testosterone.

Penile construction/phalloplasty: The construction of a penis generally includes several procedures that are often performed in tandem. They may include the following: a hysterectomy to remove the uterus, an oophorectomy to remove the ovaries, a vaginectomy to remove the vagina, a phalloplasty to turn a flap of donor skin into a phallus, a scrotectomy to turn the labia majora into a scrotum, a urethroplasty to lengthen and hook up the urethra inside the new phallus, a glansplasty to sculpt the appearance of an uncircumcised penis tip, and a penile implant to allow for erection.

Top surgery: Colloquial phrase to describe gender affirming surgery of the chest — either bilateral mastectomy or breast augmentation.

Vaginal construction/vaginoplasty: A procedure in which surgeons may remove the penis and testes, if still present, and use tissues from the penis to construction the vagina, clitoris and labia.
