Hermaphroditic species in SF

Hermaphroditism in a species, or as an evolutionary adjustment to humans.

• Asimov, Isaac. Foundation and Earth (1986) [a hermaphroditic variety of humans; one joins the protagonists]
• Burdekin, Katharine. Proud Man (1934; 1993) (A human from the future visits 1930s England; humans in the future have evolved "beyond" humanity, and beyond humanity's bi-sexed nature; each individual can reproduce on their own, and is whole, containing both male and female attributes. This human contemplates with amazement the various social oddities of modern English society.)
• Duchamp, L. Timmel. "Motherhood, Etc." (1993)
• Grae, Camarin. Stranded (1991, Naiad) (3 women from a hermaphroditic species are sent as "disembodied minds" to Earth to stop a villain. They end up identifying as lesbians and fighting a fundamentalist movement led by the villain.)
• Joyce, Graham, and Peter F. Hamilton. "Eat Reecebread" (1994)
• Ursula K. Le Guin's The Left Hand of Darkness is a type of hermaphroditism: male and female gender in potential
• Leigh, Stephen. Dark Water's Embrace (1998) and Speaking Stones (1999)
• Scott, Melissa. Shadow Man (1995) (space travel creates five common genders)

Intersexed individuals of a species, especially humans.

• Bull, Emma. Bonedance
• Carlson, William. "Dinner at Helen's" in Strange Bedfellows, edited by Thomas Scortia (1972)
• Cooney, Ellen. The Silver Rose (1979) (reminiscent of ancient greek theory: a deity's hermaphroditic child is split into two oppositely gendered beings until they re-unite)
• Samuel R. Delany. The Einstein Intersection (1967) (hermaphroditic side characters)
• Koster, R. M. Mandragon (1979) (hermaphroditic child raised as monster; then discovers or is discovered by powers)
• McMahon, Donna. Dance of Knives (2002) (minor character is hermaphroditic; apparently mutagens have caused hermaphroditism to be not uncommon)
