The inhabitants of Gethen are androgynes?, biologically bisexual humans; for approximately three weeks of each month they are biologically neuter, and for the remaining week are male or female at random. Thus each individual can both sire and bear children. (The Gethenians were genetically engineered for this characteristic long ago, possibly to maximize reproductive success on the harsh glaciated world of Gethen, or because the ancient biological engineers were curious about what such people would be like.)
