Science Fiction Story Ideas – Part 13: SEX

Science Fiction Story Ideas


Gender roles

    • In a society where women are in charge, the men are taught from infancy that having opinions or trying to make your own decisions is “effeminate” and “girly”
    • In the future, humans are born neuter but pick their gender in college, like a major.
    • A medical research company genetically engineers a group of children who are both sexes. How will they behave? How will the children dress? How will they interact with “one-sex” people?
    • After the invention of the artificial womb, newlywed couples begin to have arguments about which one of them will carry the baby.

  • After being denied a job, a young man sues a fertility clinic for his right to become the first male surrogate “mother.” A liberal judge’s ruling forces the fertility clinic to implant him with an artificial womb.
  • In the distant future, evolution dramatically changes the meaning of gender. When humans gather in groups, individuals change gender until there is an even mix of males and females. Cocktail parties become an unpredictable mass of shifting relationships.
  • After World War III, the female survivors decide that, as men caused the war and did most of the fighting, it is simply too dangerous to allow them to be in control of the governments any longer. Men are banned from government and military service and, after a few years, banned from voting, having an education or having a job outside the home. A young boy, depressed by his limited prospects at home, decides to pose as a girl so he can join the navy.
  • Variation – After World War III, the female survivors decide that, as men caused the war and did most of the fighting, it is simply too dangerous to allow them to be in control of the governments any longer. In fact, it’s too dangerous to allow men to continue living. They offer the few remaining males a choice: become women or die.


  • Earth sends a spaceship full of colonists to populate a new planet. In order to populate the new planet as quickly as possible, they send ten women for every man. Some women adjust, adapt to the new culture, accepting their role as one wife of many. Other women rebel, and have to fend for themselves on the new planet.
  • Aliens attack the earth and take the majority of the women back to their planet to be part of their interspecies breeding program. (The alien women are infertile.) So, the remaining women are left with their pick of mates. Some become incredibly choosy, dating one perfect male. Some women marry multiple husbands, so many that they can live in luxury, waited on hand and foot.
  • An epidemic outbreak of a new virus makes all men “shoot blanks.” The men must come to the doctor for fertility treatments to fix the problem. The treatments solve the problem, but create two kinds of males: “A” and “B.” Women must sleep with both an “A” male and a “B” male to get pregnant.
  • Variation – A disease makes women unable to carry an infant for a whole nine months. So one woman carries the baby for four, and then has the baby moved into another woman’s womb, who then carries it until birth.

Sexuality and procreation

  • A disease renders all the women infertile. Scientists genetically engineer women who are super-fertile, like human insect queens.
  • After the invention of artificial sperm, women start to view men as unnecessary
  • A medical research firm invents an artificial womb. Soon procreation is outlawed. Instead of sexual reproduction, corporations grow genetically engineered “perfect” babies and sell them on the open market.
  • An outbreak of disease kills everyone under twenty years old. Doctors discover that the only way to keep babies from dying is if they extend the length of the gestation period from nine months to twelve years
  • A bachelor is discovered to have a rare mutation that would make all of his offspring geniuses, physically beautiful, and nearly immortal. His sperm becomes the most valuable substance on earth.
  • Wanting to destroy the US economy, a terrorist group designs a “baby bomb,” a device that will keep women continuously pregnant
  • On a distant world, the land is filled with men. Once a year, the men journey to the beach, where they encounter the only females on the planet: mermaids.
  • On a distant planet, the corner bar is the most stressful place a man can be. Men approach women knowing that, if their pickup lines fail, the robot guards will drag them outside and beat them to death.
  • A race of aliens takes control of planet after planet, not through warfare, but through breeding. The aliens have airborne spores which can get any females pregnant with an alien baby. The babies are so adorable that any female would feel compelled to raise them as one of her own. The aliens fill the earth’s atmosphere with their spores, and simply wait for their offspring to grow up and overwhelm humanity through sheer numbers.
  • After researching reincarnation, a man discovers a way to be reborn but retain his memory of his old life. After a particularly passionate night of lovemaking, he has a heart attack and dies. A few months later, the man is reincarnated… as his own infant son.

  1. This is a fantastic page i used it for my english assignment thanks very much. The article goes into deep detail it was amazing. But one question how do you know so much about Ailen Sex??? and Ailen reproduction with humans and their life cycle when they can choose if they want to be a female or a male once they have graduated from college. It is an amazing article i really love it i hope all of the articles are as good as these. Your editors are very good and must have a great imaginiation if they wrote this from their Imagination or if it actual investigation??? i wonder if this was real what if this is how Ailens have sex like this wouldn’tit be awesome to know??? OMG i am a Sci Fi fan

  2. Of course the females are the evil antagonistic bitches in all options on gender roles, and writing as a female character wasn’t even considered. Casual sexism for the win. If sci-fi maintains this attitude it will never be woman friendly.

  3. Not to mention the perception of women as being “the other”, unlike people. They are just women.

  4. Dear Anonymous,

    Perhaps you should read through the list again. I have plenty of ideas on the list that don’t involve women being “evil antagonistic bitches”. Besides, you seem to have a narrow view of good and evil in fiction. As someone once said, everyone is the hero of their own story. Virtually every character considers their actions to be moral and just, or at least justifiable given the situation. It is up to the reader to decide who is truly the hero and who is the villain.

  5. are u a boy or a girl

  6. I’m a guy.

  7. Why would that even matter? I’m a girl, and I never considered the women being “evil antagonistic bitches.” In my opinion, in the WW3 scenarios, they are reacting to the men being apparently “evil” and “antagonistic”. It isn’t very sexist, I don’t think.

    And I never thought mermaids were “evil”, unless you sort of count the ones form Pirates of the Caribbean: On Stranger Tides, and even then…. No, those were some pretty mean mermaids…

    Anyway, what does women being kidnapped by aliens and forced to carry make them “evil antagonistic bitches”, exactly? That’s technically rape– but what I’m trying to say is that you’re being kind of sexist and hypocritical yourself, so maybe you should actually reread the prompts again as is suggested.

    And I’m a female, by the way.

  8. I’m going to merge some ideas together for a story.

  9. Sex is dirty.

  10. Only if you do it right.

  11. how is sex dirty? it’s how humans are born, how any animal is born. how it is portrayed in movies and other media makes it seem like an inappropriate thing, but it’s not inappropriate, it’s just private.

  12. You are gross!!!!!

  13. I’m sorry. :(

  14. Don’t be. ☺

  15. that is very discusting and rude, please be mature for many of us we dont need to hear that.

  16. Looks like you’ve got a school email address. Please ask a teacher how to spell “discusting”.

  17. OMG that just made me laugh my ass off thanks for that im soooo gonna use some just to make my bf laugh

  18. Wow how straightforward! Good reply though

  19. I think these ideas are great! Though I think woman exist for many more reasons than to just give birth, which seems to be the main focus in nearly all the examples.

  20. Historically, polyandry has rarely occurred in human civilizations. Any situation with few women and many men would end up with the women being fought over and enslaved by the most powerful, strongest man or men. I doubt that the women left on Earth would have their pick of mates — unless they were holed up in fortresses with laser cannons all around them.

    I suppose you could have them in a safe haven, somewhere. That’s the only way I think a story like that would work. They certainly wouldn’t be walking around in the open.

    It’s a nice dream, though.

  21. Hmm, that may be historically true, but I’ve seen it done quite well in Sci-Fi. Namely, Heinlein’s “The Moon is a Harsh Mistress”. The limited number of women on the lunar colonies makes them virtually untouchable:
    “What that means, here and now, is that women are scarce and call tune… and you are surrounded by two million men who see to it you dance to that tune. You have no choice, she has all choice. She can hit you so hard it draws blood; you dasn’t lay a finger on her….Women her age are married or ought to be… Is no rape in Luna. None. Men won’t permit. If rape had been involved, they wouldn’t have bothered to find a judge and all men in earshot would have scrambled to help. But chance that a girl that big is virgin is negligible… once a girl is nubile, she’s her own boss.”

  22. this site is actually amazing, i have to write a piece of dystopian fiction for my coursework and this has helped so much, the only way you could improve is to write the piece for me. ;P

  23. I’m glad I could help! And do your own homework. 😉

  24. I can’t believe that there are some close-minded people in this world. I don’t think that the ideas are “sexist” in fact, I think that they give the women a sense of power in the story. Think about how boring it would be to write a story abiut men as rulers of the world. The fact that women are the rulers in this scenario makes the story more interesting and that doesn’t remove the idea of a woman being the main character… just saying.

  25. Writepop is writing fiction, folks, not the Evening News. Your comments that point out your disgust over ideas of proposed fiction, prove what a mindless collection of cretins many Americans have let themselves become.

  26. I love how this section is literally titled “sex, reproduction, etc…”, and people are still repulsed by it. They made the conscious decision to click this section, and I’m just wondering what they were expecting. Squeaky clean fairytales? Haha, anyway, these are great. I’m writing a fanfiction called “Inbound Theory”, and basically it’s a collection of science fiction, romance short stories, and this has helped me a ton. Thanks!
