We have explored many worlds and many science concepts this semester.  The concepts of reproduction and sex in science fiction are broad and varied.  Most of the variations in reproduction occur in dystopian worlds.  There are very few stories of male only worlds (Ethan of Athos is one book).  The Wraethu series by Storm Constantine imagines a world where an alternate sex can create a pearl (embryo) that becomes a child.

There are several books and short stories about female only worlds which deal with sex and reproduction in different ways.  The Female Man by Joanna Russ, The Holdfast series by Suzy McKee Charnas and Ammonite by Nicola Griffith are excellent examples of alternate societies.

Some of the worlds have intentional separations of males and females while others posit a destruction of one sex.

Discuss why there are so few stories of male only worlds.
