Adding to this: If you do not want to reference the current gender, you can also use "Assigned Female at Birth" (AFAB), or "Assigned Male at Birth" (AMAB).

This is useful when clarifying terms, when you do not know the persons identity, or when discussing groups based on the factory default settings.

A female or male is not 'assigned' anything. Just because you are confused about biological reality doesn't mean it doesn't exist.

Just because you are confused about the distinction between gender and sex doesn't mean it doesn't exist.

Birth certificates record sex, not gender, no?

[bit-anarchist]

Theoretically, yes. But, sometimes, they do get it wrong.

Yep. :)
