The term "ftm" typically stands for "female to male." It is used to describe individuals who were assigned female at birth but identify as male. This term is often associated with transgender individuals who undergo or choose to undergo various forms of transition, including social, medical, and/or legal changes to align their gender identity with their gender expression.
The abbreviation "FTM" comes from the initial letters of the words "female," "to," and "male." This construct reflects the transition process and the identification as a male gender after being assigned female at birth.
