Third sex and third gender: definitions, cultures, and contemporary recognition

Characteristics and distinctions

Third-sex or third-gender identities can be based on social role, spiritual function, gender expression, anatomy, or a combination of these factors. Anthropologists and sociologists emphasize the difference between sex (biological attributes) and gender (socially constructed roles). Some individuals classified as a "third" category adopt gender expressions that blend traits associated with both binary genders, while others occupy unique social offices with specific duties.

Historical and cultural examples

Across the world there are well‑documented examples: South Asian Hijras, Polynesian Fa'afafine, some Indigenous North American Two-Spirit people, and Southeast Asian kathoey are often cited. Each tradition has its own history, rituals, and social meanings; none are identical, and local terminology and acceptance vary widely.

Contemporary recognition and issues

In recent decades some countries and institutions have begun to recognize non-binary or third categories in law and documents, offering an alternative to male/female markers. Legal recognition can affect access to healthcare, anti-discrimination protections, and identity documents. Activists emphasize that social recognition and respectful treatment are as important as legal categories.

Notable facts and distinctions

• "Third" does not imply a single global identity—terms and meanings are culturally specific.
• Some people prefer the term non-binary or genderqueer rather than "third sex."
• Medical, legal, and religious institutions approach these categories differently, producing varied outcomes for individuals.

Because the subject intersects anthropology, human rights, medicine, and law, careful, context‑sensitive language is important. For general background on related concepts see entries linked as third gender, or pages about man and woman.
