RGAB means Reassigned Gender After Birth
This refers to the experience of an intersex person having their gender scrutinized (usually in early childhood but sometimes at puberty), and ultimately reassigned socially and often medically. This is done due to the intersex person's original AGAB having been determined to be more difficult to impose due to their body. This is a form of ISIG (Inconsistent Societally Imposed Gender).
Examples:
AFAB-RMAB refers to an intersex person assigned female at birth, but reassigned male after birth. A reason for this may be due to a child who had a vulva at birth later being found to have testicles, XY chromosomes, undergoing testosterone-dominant puberty, and experiencing masculinizing of their genitalia, such as significant growth of the genital tubercle (clitoris), to the point it could be classified as a clitorophallus or phallus, etc. Due to this, it would be determined to be "more accurate" or "easier" to reclassify the individual as male.
UAB‐RFAB / UAB-RMAB refers to an intersex person not assigned at birth but assigned female or male after birth. A reason an intersex person may be unassigned at birth is having ambiguous genitalia, or a lack of external genitalia. Sex determination in this case is generally based on sex characteristics which require further testing to observe combined with the biases of the parents and doctors. The vast majority of intersex people UAB will experience RGAB.
AMAB-RFAB refers to an intersex person assigned male at birth, but reassigned female after birth. A reason this may be due to a child having a large genital tubercle structure that could be classified as a phallus. The child may later be found to have XX chromosomes, a uterus, small or closed vaginal opening, go through estrogen-dominant puberty, etc. Due to this, it would be determined to be "more accurate" or "easier" to reclassify the individual as female.
This is not an acronym for voluntary gender reassignment gotten by trans people. Do not misuse intersex terminology.
