* An episode of ''Series/{{Sliders}}'' had the Sliders land on a world where the bulk of the male population was killed in biological war. The result is that remaining men are kept in facilities with the intent of using them to breed future generations. This goes to ridiculous extent that the two world superpowers (based on male population count): US and Australia, constantly steal each other's males. Men are rated on a number of "encounters" per month. A particular stud is famous for having the average count in the 200s (that's over 6 women per ''day''), and a man is forcibly separated from his wife and placed in a repopulation facility. And she's not allowed to even see him, much less sleep with him, because she's ''not attractive enough'' for their eugenics program. Professor Arturo laments the lack of artificial insemination technology on this world, and he'd be happy to help them out, if only they cared what he had to say instead of how many "encounters" he could have in a day.
* Obligatory ''Franchise/StarTrek'' Example: In ''Series/StarTrekEnterprise'', there's an episode with a species who have 3 genders, where the third gender doesn't pass on any genetic material but their involvement is still necessary for the male and female to successfully reproduce. The "cogenitors" are treated in a manner not befitting pet hamsters- They aren't even given names, let alone education or freedom. (the cogenitors make up less than 3 percent of the population, setting themselves into this trope nicely)
* The ''Series/DoctorWho'' serial "[[Recap/DoctorWhoS3E1Galaxy4 Galaxy Four]]" features this with the Drahvins. We only ever meet the females and their leader, Maaga, is initially confused when the Doctor's companion Steven asks about their men. When she does understand her response is an offhand remark that they keep as many males as they need and simply kill the rest.

* In ''[[HGame Meet and fuck: Star Mission]]'', males have declined "due to a succession of wars". Males are kept in cryostasis untill TheFederation needs a few sperm samples, thawed, thrown a sandwich and a vial. Once the samples are collected, they get stuck back in the freezer and shipped to another colony.
* With one exception involving TimeTravel, players only ever see female Mithra in ''VideoGame/FinalFantasyXI.'' They are, mechanically, an all-female race. They ''do'' have males, but according to [[AllThereInTheManual the game's backstory]], males are rare and kept sheltered to ensure their species' survival. They typically stay home and raise the kids while the females hunt and adventure.

* In Creator/WenSpencer's ''Literature/ABrothersPrice'' male children are a lot rarer then female children which results in a society with reversed traditional gender roles and arranged polygamous marriage between a man and multiple women (usually sisters), and by multiple think anywhere from 5 to 30. Also a literal Gender Rarity Value, a "[[ExactlyWhatItSaysOnTheTin Brother's Price]]" is how much a family gets for selling their brother. Usually it's just a swap for another family's brother or a straight sale to a family for cash. The male ends up marrying all the women in the new family. However there is also the option of selling him to a "Crib" aka whorehouse, where he'll spend the rest of his life drugged to the eyeballs on fantasy world viagra impregnating women who can't afford to buy a husband.

* The gender imbalance among the Chinese population in the United States is remarkable in the late 19th and early 20th century. The male/female ratio went far as 25 to 1 in the 1890 census, because most came in as manual laborers with either not married or have families but left behind in China and only the privileged can bring their families. It wasn't until after World War II when family lives began and the gender ratio balances beginning in the 1960s with a massive influx of immigrants.

* In ''[[TabletopGame/{{Warhammer}} Warhammer Fantasy Battles]]'' only one tenth of all dwarfs are born female. Dwarf holds are ruled over by kings and women hold little political power but are still highly respected in their society. Women may marry more then one man in which case they are encouraged to marry brothers.

* Ubiquitous in agricultural animal husbandry, in which female animals' ability to produce milk, eggs, and offspring routinely gets male livestock converted into meat at a younger age than their female counterparts. The exceptions are the valuable "stud" males, whose high-quality genes ensure them a long and pampered lifespan, long after most of the lower-grade males of their generation have been sent to the slaughterhouse.

* An episode of ''Series/{{Sliders}}'' had the Sliders land on a world where the bulk of the male population was killed in biological war. The result is that remaining men are kept in facilities with the intent of using them to breed future generations. This goes to ridiculous extent that the two world superpowers (based on male population count): US and Australia, constantly steal each other's males. Men are rated on a number of "encounters" per month. A particular stud is famous for having the average count in the 200s (that's over 6 women per ''day''), and a man is forcibly separated from his wife and placed in a repopulation facility. And she's not allowed to even see him, much less sleep with him, because she's ''not attractive enough'' for their eugenics program.

* The Rainbow Cadenza by J. Neil Schulman is a rare example of ''both at the same time;'' It all starts cheap sex-selection technologies, specifically an over-the-counter drug called Adamine which suppresses the production of X-chromosome-carrying sperm, ensuring that any child a man sires while taking the drug is male. In anticipation of World War Three, first-world nations approve tax incentives supporting the use of the drug, hoping to breed a critical mass of soldiers to be drafted. As a result, an entire generation almost totally eschews bearing female children. In the aftermath, males outnumber females by a factor of 20. And many of them have PTSD. And do to the remaining women what crazy, violent men have done throughout history.\\

* While the casualties of the UsefulNotes/WarOfTheTripleAlliance are a source of great controversy, one thing that is universal is that they were disproportionately male, with the sex ratio going from fairly even before the war to anywhere from 4 to 20 women for every man depending on the area. It's one of the few, if only exceptions to the Catholic church's ban on polygamy, simply because there were so few Paraguayan men left.

* ''Masters of the Fist'', a collection of short stories by Edward P. Hughes: in the aftermath of WorldWarIII, all the men in a certain Irish village have gone sterile, except for a [[BritsWithBattleships British Army]] sergeant who salvaged a Challenger tank and used it to defend the place from brigands. A council of village elders therefore decrees the sergeant to now be the village's "lord,"[[note]]pretending that it's just because he's the guy with the tank[[/note]] who must deflower every girl of the village just before her wedding. He isn't very happy about it, especially since one of the council, the schoolteacher, is the only woman he ''really'' wanted ... but he's not allowed to marry her, because he has to be the village's stud. He's also rather squicked when the process has gone on long enough that most or all of the girls these days are [[ParentalIncest his daughters]].

* ''Literature/{{Discworld}}'''

* In ''Literature/DragonridersOfPern'', the golden "[[WhatDoYouMeanItsNotSymbolic queen]]" dragons are ''both'' the rarest dragons and the only fertile females. Queen dragons make up about five percent of the entire dragon population, while greens (the smallest and lowest-ranking) are about half the population. Interestingly, greens are also female, and are only sterile because (like the males) they are fed firestone to allow them to breathe flame. Brief scenes involving a young gold dragon seem to suggest that if they were to withhold firestone from a green (either from hatching, possibly allowing them only a small ration thereof; or from a mature green) they may produce viable clutches. This does produce mild FridgeLogic moments with the primary plot point from the first novel, but they may be HandWaved or justified by the fact that it's said that green clutches produce smaller, weaker hatchlings than gold clutches. Also, only golds produce another gold, one per clutch or less. When you need dragons to keep your planet from being devoured by Thread, you want big, strong dragons with stamina, thus from golds and not greens.

* Although now relegated to [[CanonDiscontinuity "Legends" continuity]], the ''Franchise/StarWarsExpandedUniverse'' portrays a vast number of different species with different takes on society due to their gender imbalance.

* Female children are rare among the ''Literature/{{Discworld}}'''s Nac Mac Feegle. These girls become Keldas, leaders of Nac Mac Feegle clans. The fact they're a lot smarter (and saner) than most of the men helps too.
** A concussed duckling is saner than most of these men.

* The settlement of the WildWest. Most of the Frontier towns started as ''work camps'', where there were no women. Most of the men who came to those camps had left families behind, or did not have any family to begin with. When women finally ''did'' come to the West, they saw that there was a high demand for sex, and since there weren't many other ways for women in the 1800's to make money, they found that TheOldestProfession, despite its many downsides, was a very lucrative career. In fact, many of them made many times more money than their clients did on a day-to-day basis! (And if and when they ''did'' decide to get married, this wasn't [[MadonnaWhoreComplex held against them]] as much as it would have been further East, because women were at such a premium, regardless of whether they were current or former saloon girls, or virgin {{Schoolmarm}}s.) Many of the prostitutes and madams of the Old West used their newfound wealth and power to turn those settlements from work camps, to actual towns with (non-sex-related) services that people really needed. This financial independence gave women in the West a level of power and influence that women further East would not have for ''decades''.

* Boys are born slightly more often than girls but are slightly less likely to survive to adulthood, [[MenAreTheExpendableGender due to being far more likely to be the victims of violent crime]] as well as the fact that men are more likely to inherit certain genetic diseases like hemophilia due to only having one X chromosome, not to mention that a large number of high-risk jobs are primarily performed by men (construction, law enforcement, the military.) The differences (on the order of 1% either way, depending upon culture) are far too small to constitute rarity.

The result is that remaining men are kept in facilities with the intent of using them to breed future generations.

And she's not allowed to even see him, much less sleep with him, because she's ''not attractive enough'' for their eugenics program. Apparently, even with the absence of men women are still obsessed with beauty, although that could just be an artifact of a male-dominated culture.

** Dathomiri, as seen in ''Literature/TheCourtshipOfPrincessLeia'', are a matriarchal human subspecies of [[WitchSpecies Force Sensitive]] who developed a culture in which males are oppressed and even unconsciously prevented from mastering their own Force powers due to influence from a female Dark Jedi in their distant past. The story itself has Luke arrive on the planet and be immediately enslaved, as his being a "male witch" makes him incredibly attractive as a potential mate. However, he later proves to be largely playing along, not seriously threatened. Also, the Nightsisters -- an outcast clan of Dathomiri who embrace the Dark Side -- are even worse than the regular Dathomiri, with a tendency to ''execute' their males after mating with them. Even in the canon depiction of Dathomir in ''WesternAnimation/StarWarsTheCloneWars'', the Nightsisters are still a LadyLand {{matriarchy}} who ruthlessly subjugate their Nightbrothers.

* On the ''Literature/HonorHarrington'' planets of Grayson and Masada, women outnumber men three-to-one due to Grayson's heavy-metal-rich environment causing high infant mortality in boys, but it's the men who are in charge. This is largely due to a religious beliefs that held women were incapable of bearing serious responsibility in men's areas. Graysons, at least, had become fairly chivalrous about this in recent years, whereas the Masadans were full-on {{He Man Woman Hater}}s.

** Many monsters are more likely to appear as one gender over the other. The [[StarterMon Starter Pokemon]], [[PrehistoricMonster Fossil Pokemon]] and many others like Eevee and Lucario have a gender ratio skewed to favor males and only 12.5% (or one in eight) are females. This specific gender ratio is put in place mainly to make it harder to breed more of them as [[GenderEqualsBreed females determine what species hatch from eggs]].
** At least two species (Combee and Saladint) need to be female in order to evolve and they also have the same gender ratio.

** ''Webcomic/PennyArcade'' parodied ''VideoGame/{{Fallout}}'' with Vault 43: 20 men, 10 women, [[BreadEggsMilkSquick and one panther]]. Presumably the panther helped even out the gender ratio a bit- or made things worse.

* The ''VideoGame/{{Fallout}}'' series' Vault 69 had with in 999 women and one man. The women fought and killed each other over the sole male. There is also Vault 68, with 999 men and one woman, but what happened within it is unknown.
