Müllerian

Müllerian is an alternative term for biological female. It is a synonym for female-bodied, used to describe someone that is of the female sex.

Müllerian individuals have at least two of any of the following features

• a vagina
• a vulva
• a uterus
• oviduct(s)
• XX chromosomes
• an ovary or ovaries
• a cervix
• skene's gland(s)

Or they at least

• are capable of producing ova
• are capable of conceiving
• have estrogen as their dominant, primary hormone (unless they lack all other previously listed features)

Ideally, a Müllerian refers to a cissex dyadic individual who is was correctly assigned female at birth. However, the term can apply to male-to-females that are both transgenital & transhormonal, and sometimes CTF individuals, as phenotypic sex is the primary classification for sex at large. Transsexual females (that are AMAB) being excluded from the Müllerian category is a transphobic practice, as it excludes trans females from female categorizations and separates them from the female identity, despite them being both anatomically and psychologically female. Through a sex-binary lens, someone may also identify as Müllerian if they lack the majority of dominant wolffian traits.

The term is a less-gendered approach to biological identification. The term 'biological female,' while technical and correct, is often used by transphobes to reduce trans men down to their anatomy. Still, should Müllerian not be used for someone outside of a medical, biological or anatomical context.

Müllerian is not synonymous with being assigned female at birth, for reasons being that individuals assigned female at birth can be wolffian or CTM, ASAB labelling can be mistaken for intersex individuals, and that not every Müllerian is AFAB.
