Single-gender world

A relatively common motif in speculative fiction is the existence of single-gender worlds or single-sex societies. These fictional societies have long been one of the primary ways to explore implications of gender and gender-differences in science fiction and fantasy.^[1] Many of these predate a widespread distinction between gender and sex and conflate the two.

In the fictional setting, these societies often arise due to elimination of one sex through war or natural disasters and disease.^[2] The societies may be portrayed as utopian or dystopian, as seen in pulp tales of oppressive matriarchies.
