f2m

F2m, commonly written as F2M or F-to-M, is an acronym used to describe a person who was assigned female at birth (AFAB) but identifies as male. The term is used in transgender and gender-identity contexts and is often interchangeable with the more person-centered label trans man. Some people prefer transmasc as an umbrella term for masculine-presenting transgender people, while others identify specifically as a man.

In practice, F2m signals a gender identity that aligns with male, and may accompany a range of transition steps chosen by the individual. These steps can be social (changing name, pronouns, voice or presentation) and/or medical (hormone therapy, surgical procedures). Transition timelines and choices vary greatly between individuals.

In data collection and clinical contexts, F2m may appear on forms and databases to indicate gender identity. However, many guidelines encourage asking for the individual's preferred name and pronouns rather than relying on binary labels alone.

Related terms include FTM (the older variant often used interchangeably with F2m), trans man, and transmasc. It's important to respect each person's self-identification, pronouns, and terminology, and to avoid assuming a fixed path or identity based on birth sex alone.
