* The ''VideoGame/BattleTanx'' games on Nintendo 64 and [=PlayStation=] had a plague wipe out 99% of the female population. The remainder were dubbed [=QueenLords=] and the remaining men [[ExcusePlot fight over them with tanks.]] The sequel reveals [[spoiler:the plague was unleashed by Cassandra, a psychic who wanted to weed out any females unable to use [[PsychicPowers The Edge]].]]
* The Hrothgar in ''VideoGame/FinalFantasyXIV'' have a staggeringly low female populace, which makes seeing one in the open nigh unheard of. What little females that are there are revered and protected, giving rise to the matriarchal culture the Hrothgar have and crowning one as their queen. The males take the name of their queen as their surname, with the A- prefix denoting their continued service, or the -sch suffix for the one they left service to, usually as a result of their passing.
* The Gerudo in ''Videogame/TheLegendOfZeldaOcarinaOfTime'' have only one male child every 100 years, and he becomes their king. Unfortunately, one male child, [[BigBad Ganondorf]], isn't happy being the king of ''just'' the Gerudo.

* The ''Series/{{Sliders}}'' episode "Love Gods" is a rare example of Type 2 set in a LadyLand. A biological weapon released in the Gulf War kills off most of the male population, and the few who survived are confined to forced breeding camps. Their accommodations are relatively luxurious, which gives the initial impression of a Type 1 example, but it is a GildedCage.

* The two warring factions in the GirlsLove SpaceOpera ''Webcomic/{{Angels 2200}}'' appear to have chosen opposite versions of this trope following the male {{gendercide}}: The Colonials appear to have opted for version one with males in command positions while the [[LadyLand Terrans]] appear to have opted for version two since none of their males have ever appeared at all, which is not surprising, considering the Terrans created the [[TheVirus Gendercide plague]] in the first place. One Terran pilot claims that her father didn't die in the plague: he abandoned his family to become a playboy afterwards.

* ''Hell Comes to Frogtown'', in which "Rowdy" Roddy Piper plays Sam Hell, one of the last fertile men on Earth (and is thus in high demand). Along with Sandahl Bergman doing a sexy dance and a man-sized frog with [[spoiler:a three-headed penis! Who utters the [[SoBadItsGood classic line]] after Bergman's dance: "You have aroused the three-headed snake!"]].

* Boys are born slightly more often than girls but are slightly less likely to survive to adulthood due to a number of various factors affecting their survival: Men are more likely to inherit certain genetic diseases like hemophilia due to only having one X chromosome, men are also more likely to take risks with their lifestyles ranging from high-stress or high-risk occupations (such as applying to the military) and hobbies (Like extreme sports) to not paying much attention to their own physical health. Even when they don't take risks, there is the military draft which usually only drops men into war, even when there's a shortage, and men are more likely to be targeted for violent crime and even murder unless the motivation is specifically gender-based. The differences (on the order of 1% either way, depending upon culture) are far too small to constitute rarity.

* The ''Series/StarTrekVoyager'' episode "Favorite Son" features a species called the Taresians, whose population is only 10% male, leading to the males being highly prized and honored with [[ExoticExtendedMarriage multiple wives]]. An important plot point is Harry Kim turning out to be a Taresian implanted in a Human womb and therefore growing up Human until his hidden Taresian genes kick in. [[spoiler: Ultimately, this is {{Subverted}} by both Harry not really being a Taresian (he was secretly implanted with their genes) and Taresian males [[OutWithABang dying on their wedding nights]] so that their wives can absorb enough genetic material to reproduce.]]
* ''Series/WonderWoman'': Steve Trevor is the only man that has reached LadyLand HiddenElfVillage Paradise Island in millennia. [[WhatIsThisThingYouCallLove The younger amazons have strange feelings]], so Queen Hippolita declares an amazon will escort him to his country.

* 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).

* This plays a huge role in ''Manga/AnimalX'', as [[MisterSeahorse Yuiji's]] ability to bear dinosauroid children makes him a LivingMacGuffin and the target of multiple rapes and rape attempts. The fact that the dinosauroids are dying out drives almost all of the politics on their side, and all of the politics on the human's side barring those who are only in it ForScience. That said, ''Manga/AnimalX'' appears to be actually mix of type I and II, [[BlueAndOrangeMorality as every female non-barren dinosauroid is expected to bear children non-stop, but most dinosauroids consider this a great honor and see polyandry as normal and expected.]] [[note]]A female non-fertile dinosauroid is DesperatelyLookingForAPurposeInLife because despite being the strongest warrior in her tribe and highly respected for her skills, her inability to bear children makes her feel like a failure.[[/note]] It's unclear if Yuiji might be treated better [[FantasticRacism if he was a pure dinosauroid and not a mutated human,]] or if he was capable of carrying pure dinosauroid children instead of [[HalfHumanHybrid human-dinosauroid hybrids]].

** For Salarians, the race is 90% male, but they rarely wield political power. The females wield the highest ranks through being clan matriarchs. This is subverted for the Salarians, however, because the females closely regulate the gender of their children, enforcing the 90/10 ratio. There's a logical reason for their doing so, as well. Salarians are "haplo-diploid oviparous" reproducers. Basically, females lay eggs frequently (at least once a year, if not more), even without any sexual contact; unfertilised eggs hatch as males, fertilised eggs hatch as females. This is balanced by a 40-year lifespan, but the salarian colonies still tend to require careful self-regulation to avoid overpopulation.

* Plenty of Sci-Fi [[BoysLove Yaoi]] mangas have the setting of a severe lack of women, leading to those women only interacting with the best of the best (by choice or by force) while the lesser men enter homosexual relationships for love and sex. Alternatively, some of the "good" men buy themselves lesser men for entertaining purposes. The most famous example for the latter would be ''LightNovel/AiNoKusabi''.

* Men in ''[[Manga/{{Ooku}} Ooku: the Inner Chambers]]'' land on this side of the line. When rather more than 75% of men die before adulthood from the endemic Redface Pox the survivors are protected from danger and strenuous activity wherever possible (women have taken over everything from farming to fishing to smithing). However men have also been crowded out of government (too stressful for their delicate constitutions) and few think twice about pimping out boys as young as fourteen to women seeking children. Male children are expected to provide a steady source of income to their families. Only wealthy women can afford to buy a man's exclusivity and marry him; only the shogun is powerful enough to have a harem of men kept for her exclusive use.

* In ''Manga/{{Ooku}}'', due to the Redface Pox, women outnumber men 4:1. As a result of the Gendercide being due to health reasons, men basically don't have to do anything except breed: women didn't stop doing household chores, they just took over traditionally male work as well. Having a husband becomes extremely expensive and most women resort to male prostitutes to have an heir. Only men in the Ooku have any form of political pull that isn't the result of being married or a son to anyone with political power.

* An ''extremely'' popular case of FanWank in the ''WesternAnimation/MyLittlePonyFriendshipisMagic'' fandom, given how few male characters there are compared to the female roster both as main, background and supporting roles (although the newer seasons have evened this out). Many FanFic authors have explored or at least mentioned the phenomenon in passing. Sometimes it is {{Deconstructed}}, used as justification for a [[{{Harem}} herd-style society]], or simply to "[[YuriFanboy explain]]" why everyone is gay.

* ''Literature/AMemoirByLadyTrent'': Eighty percent of [[spoiler:[[DraconicHumanoid Draconeans]] are born female, and the few males serve as priests and scribes, while the females occupy most of the labor, leadership, and warrior roles.

* Plenty of Sci-Fic[[BoysLove Yaoi]] mangas have the setting of a severe lack of women, leading to those women only interacting with the best of the best (by choice or by force) while the lesser men enter homosexual relationships for love and sex. Alternatively, some of the "good" men buy themselves lesser men for entertaining purposes. The most famous example for the latter would be LightNovel/AiNoKusabi.

* 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 merchant class can bring their families. It wasn't until after World War II when the exclusion acts were repealed, family lives began and the gender ratio becoming balanced beginning in the 1960s with a massive influx of immigrants.
* 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. The casualities in Paraguay were the worst, with nearly ''90%'' of Paraguayan adult males killed. It was so bad that UsefulNotes/ThePope actually temporarily permitted polygamy there (a practice otherwise wholly forbidden by Catholicism) to bring up the birth rate after this.

** An episode involves travel to {{Alternate Dimension}}s by way of cardboard boxes. Prof. Farnsworth sticks his head into one, and withdraws it, covered in lipstick prints. He comments: "All women! I think I'll put this one aside for later."

** 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.

** In ''Fanfic/FalloutEquestriaProjectHorizons'', Stable 99 is a "rare gender is enslaved" variant masquerading as a
"rare gender is worshipped" variant. A highly tradition-based society dependent on strict population control, stallions (or "bucks" as they are called) are kept as a small minority[[note]]40 stallions to 500 mares[[/note]] and given no rights or liberties whatsoever; they are considered breeding stock and fit only to provide reproduction and sexual release, with the mares being [[ConditionedToAcceptHorror culturally indoctrinated]] to genuinely believe that stallions only care about breeding and [[DoubleStandardRapeFemaleOnMale don't need to explicitly consent to sex]]. Because of this brutally utilitarian view of the genders, stallions in Stable 99 have a limited lifespan, and are [[InsistentTerminology "retired"]][[note]]executed and [[HumanResources broken down into protein]] to feed the survivors[[/note]] once they age past 40 and their sexual viability declines.

* An ''extremely'' popular case of FanWank in the ''WesternAnimation/MyLittlePonyFriendshipisMagic'' fandom, given how few male characters there are compared to the female roster both as main, background and supporting roles (although the newer seasons have evened this out). Many FanFic authors have explored or at least mentioned the phenomenon in passing. Sometimes it is {{Deconstructed}}, used as justification for a [[{{Harem}} herd-style society]], or simply to "[[YuriFanboy explain]]" why EveryoneIsGay.

* 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, unless they split it between older and younger sisters. 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.

* In China, male children currently outnumber females about 117 to 100 in the recent generations. Since the beginning of the One-Child Policy in 1978, [[https://en.wikipedia.org/wiki/Missing_women_of_Asia female fetuses have been aborted more often than males and newborn girls are sometimes killed or abandoned]]; this is the result of the law interacting with the tradition in China is that the men carry the family name and take care of their parents in their old age[[note]]the Policy was changed to two children in January 2016, so it's too early to tell how much the demographics will change in the future[[/note]]. This is especially common in rural areas where traditional social norms may be the only safety net for the elderly. It is significantly less common in wealthier urban areas, where women have much greater access to education and jobs and their contribution to the household is viewed more equitably. The rural shortage of women has made it increasingly difficult for young men to find wives and has sometimes resulted in internal and international human trafficking because families are willing to pay substantial sums for a bride, consenting or not. The Chinese government has been working to raise the status of female children and end these practices but attitudes change more slowly than laws.

* ''WebOriginal/ChakonaSpace'': Only one in four Foxtaurs is male. Most women do the hard work in the foxtaur-dominated towns so they can earn the 'obligation' to mate with males, who culturally have less political influence in most matters. [[note]]This gender imbalance was likely intentional, alongside the Foxtaurs' original purpose as SuperSoldiers.[[/note]]

* Lurks at the heart of the GenderBender manga ''Balance Policy'': The world is undergoing an infertility plague with female births account for only 10% of the diminished total, so the world's governments have hit upon the solution of converting pre-pubescent boys into girls. The boys modified under this so-called "Balance Policy" are supposed to be chosen for their suitability, but the lure of substantial government incentives convinces some parents to force their sons into the program. The resulting reluctant girls naturaly act out their hurt, confusion, anger and resentment at this betrayal, and even the resigned or more-or-less willing ones have issues stemming from the implicit message that they are supposed to be promiscuous breeding stock.
* Played both ways in ''Manga/OnePiece.'' The "Isle of Women", Amazon Lily, forbids men to step upon it on pain of death. This works so well that only the oldest woman on the island could even ''identify'' a man when she saw one, since all the women who leave the island for supplies and what not and know what males look like are just coming back to the island. However, once [[IdiotHero Luffy]] [[DefeatMeansFriendship befriends]] Boa Hancock and gains her permission to be on the island, the women can't get enough of him and are eager to just touch him before he leaves.
