All-woman worlds encounter men

When the men come back ...

A world of all-women encounters, or is encountered by, men, for good or ill.

• Forrest, Katherine. Daughters of a Coral Dawn. A race of human women leave earth to set up their own world. Eventually a ship from earth, with males & females, encounters this world.
• Maine, Charles Eric. Alph (also published as: World Without Men (anti-feminist; an all female world finds a surviving man)
• Mushroom, Merril. 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 ...
• Reed, Kit. Little Sisters of the Apocalypse (An island of women whose men have gone off to war must decide what to do if / when the men come back.)
• Russ, Joanna. "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.
• Tiptree, James, Jr. "Houston, Houston, Do You Read?" (1976) - a spaceship of men encounters a future earth populated only by women.

• David Brin, Glory Season - Not quite an all-woman world, but a predominantly woman world settled by feminist social experimenters, now must prepare to meet the rest of humanity.
