The DMAB flag.

An alternate AMAB flag.

The AMAB trans flag.

Assigned Male At Birth (AMAB) (also seen as Designated Male At Birth (DMAB) or Male Assigned At Birth (MAAB)) is an assigned gender for those who have external sex traits that were identified as male. It is used as a way to refer to the sex on one's birth certificate or to discuss medical issues that primarily face AMAB individuals without making assumptions about one's current sex, body, or gender.

When one is born they are said to be male based on the presence of a penis, or a clitoris over a certain size. The presence of a vagina (the internal structure) is not checked. Some intersex individuals who were AMAB only discover they have a vagina once they are older. Chromosomes are also not checked, so someone who was AMAB doesn't necessarily have XY chromosomes.

Traits commonly found in those who are AMAB include:

  • No vagina or uterus. However, some who were AMAB were born with one of them (persistent müllerian duct syndrome).
  • A penis or large clitoris (POP). With some intersex conditions, the difference between these can be unclear.
  • Descended testes and scrotum, although sometimes testes never descend (cryptorchid), are underdeveloped, or are removed later in life (angenital.)
  • The capacity for spermatogenesis unless if sterile, or without some of the anatomy listed above.
  • Has testosterone as their natural primary sex hormone.
  • Chromosomes that are XY.

AMAB individuals who were born with all of these traits are considered dyadic or wolffian, though some dyadic individuals may loose some of these traits later in life. Not all who were AMAB were born with all of these traits, in which case they may be considered intersex. Some intersex individuals were AMAB, because they appeared externally male and their condition is not obvious without genetic testing or was not noticed until later in life. Some intersex individuals were coercively assigned male at birth (CAMAB), meaning they were medically altered without their consent to fit the sex binary.

AMAB individuals are typically raised with the assumption that they will identify as a man, however AMAB individuals can be any gender and can have any gender presentation. AMAB men are considered cisgender men. Transgender AMAB individuals are most commonly assumed to be trans women, however non-binary AMAB individuals can also be considered trans. AMAB individuals who identify primarily with femininity can be called transfeminine.


The DMAB flag was created by arco-pluris on the Tumblr blog beyond-mogai-pride-flags on October 15, 2020.[1] The blue and red stripes represent cis AMAB individuals and trans AMAB individuals. The yellow and grey stripes represents AMAB individuals who identify as gender modalities other than cis or trans.

An alternate flag was created by Tumblr user plurgai on February 19, 2021.[2] It has no known meaning.

The flag for trans AMAB individuals was created by an unknown user on or before August 23, 2015.[3] Dark red is for trans women. Light red is for those who identify partially as a women. White is for agenders, and anyone who lies outside of the male/female spectrum (abinary). Purple is for those who identify as men and women, or are in between men and women (androgyne/ambinary). Light blue is for those who identify partially as men.
