Leptrois

Leptrois or the leptral gender system is a form of leptive gender classification.

Under leptrois, each gender has an associated spectrum ranging from negatrois (antigender) to positrois (eugender), with centrois (nongender) at the center.

Additional classifications include neutrois, which is positioned at centrois for every gender, and nulltrois (zerogender), which is simultaneously positioned at both negatrois and positrois for the same gender.
