The Gethenians are inhabitants of the fictional planet Gethen, featured in Ursula K. Le Guin's novel, "The Left Hand of Darkness." They are unique for their ambisexuality, meaning they can adopt male or female reproductive roles depending on their circumstances and relationships. This biological trait influences their social structures and cultural norms, allowing for a fluid understanding of gender. Gethenian society is characterized by a strong emphasis on community and cooperation. Their political systems often revolve around alliances and consensus rather than hierarchical leadership. The planet experiences extreme cold, which shapes their way of life, including their clothing, housing, and social interactions.
