Male Scarcity

• Poul Anderson. Virgin Planet (1959) (sexist; an all-woman world (reproducing by a poorly-described parthenogenetic cloning) has been awaiting the coming of Man.)

Doctors are able to use this method to fuse two eggs together in a woman. Pregnancy and childbirth are normal and the child inherits both parents' genetic material.

As it happens, there is a completely functional all-women world — but a few men are hiding out. Since they are not incorporated into the main society in any fashion, this still qualifies as a woman-only world.

• A. R. Morlan. "The Best Years of Our Lives" (1993) (in Full Spectrum 4) (most men have died; women begin outdoing men at warfare)
• Merril Mushroom. Daughters of Khaton. Actually, it's not exactly clear that women are reproducing parthenogenetically, or if a plant is just making babies for them. The plant definitely seems to be doing it, but somehow by taking the genetics of the women ...
• Anne Rice, Queen of the Damned. Akasha wants women everywhere to rise up and kill most of the men because of their violence.
• Leigh Richards. Califia's Daughters. After a biological disaster, women outnumber men and men are prized above all things.
• Joanna Russ. The Female Man. The classic women-only world. Actually, there are several worlds portrayed, but one of them -- Whileaway -- is a women-only world. --. "When It Changed" (initially published: 1972, in Again, Dangerous Visions, edited by Harlan Ellison) (This was the first story published about Whileaway. In this story, Whileaway is "found" by men from Earth, who think it a tragedy that men have disappeared from the world 30-odd generations ago, and promise to rectify the situation. This story was a "dangerous vision": women have created a world and lived just fine without men; this was not a feminist utopia, but the women have done just fine and apparently not missed men at all. What kind of world do you have when you have only one sex? A world of people.

Read The Female Man for more Whileaway; or read Nicola Griffith's Ammonite for another very human world in which neither the people on the planet nor the reader ever miss males. For more encounters between all-woman societies and men, see: Tiptree's "Houston, Houston, Do You Read" and Merril Mushroom's Daughters of Khaton.
