Neutrois is a which is often associated with a "neutral" or "null" gender. It may also be associated with genderlessness and shares many similarities with agender- people who consider themselves neutrally gendered or genderless, but some may identify as both, while others may prefer one term or the other. Generally speaking, neutrois is a transexual identity, meaning that it involves gender dysphoria and a desire to make a physical transition to a gender-neutral presentation.
The word "neutrois" was created by a self-identified neutrois person named H. A. Burnham in 1995. The word "neutrois" is presumably made from French neutre, meaning "neutral" or "neuter," and French trois, "three" as in a third gender.
Neutrois isn't another word for androgyne. According to Neutrois Outpost, the difference between neutrois people and androgynes is gender dysphoria: "While Neutrois seek an androgynous appearance, androgynes aren't Neutrois because being Neutrois involves gender dysphoria. Androgynes don't necessarily have any difficulties with their gender identities."
