AXAB - Assigned X at Birth, also Designated X at Birth (DXAB) or X Assigned at Birth (XAAB).
This term is typically used for babies with intersex traits. AXAB most commonly is used for someone whose external sex traits could not be neatly identified as female or male. Assigning such classification at birth is not common practice and is only seen in certain cultures and regions where genders and sexes outside of the male and female are recognized.
