The Last Amazon

Originally, Sparta was an all-male planet - an all-male population with everything that implies: babies - male babies only - produced by the so-called Birth Machine from an almost unending supply of fertilized ova brought by Sparta's founding father, a dyed-in-the-wool misogynist.

But there was still something rather strange about Sparta when John Grimes landed there to await the arrival of his beloved ship Sister Sue.
