** The Gerudo are an entirely female human race of warrior-thieves, who are expected to leave the desert, usually temporarily, if they're inclined to find men to make more Gerudos. Oddly enough, though ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' states that one Gerudo male is born every hundred years, there is no special fanfare beyond being appointed king by tradition (the only one known is [[BigBad Ganondorf]] which doesnt work out too well...). The point may be moot, as the ''Creating a Champion'' artbook states that by the time of ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'' a male has not been born to the Gerudo for countless millennia.

* The Dracs from ''Film/EnemyMine'' are masculine ("I... am ''not''... ''a woman!''"), but reproduce asexually. [[* [[Literature/TheEnemyPapers The books on which the movie is based]] state that yes, Draks ''can'' have more than one child in their lifetime, but [[spoiler:something has gone wrong with Jerry, resulting in his DeathByChildbirth]]. The books also confirms that Dracs don't ''always'' reproduce asexually, and that ''falling in love'' can result in pregnancy all on its own.

Longyear books on which the movie was based stated that yes, Draks ''could'' have more than one child in their lifetime, but [[spoiler:something had gone wrong with Jerry, resulting in his DeathByChildbirth]].

** Gorons all identify as male, referring to each other as "Brother." This could be the case of identity rather than biological sex or they could be {{Truly Single Parent}}s, since all cases of child Gorons seen in the series only have fathers and mothers are never mentioned. The manga of ''Ocarina of Time'' has a few female Gorons that are only visibly different due to [[TertiarySexualCharacteristics long eyelashes]]. ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]'' references this ambiguity by showing that two Goron men have been allowed in the women-only Gerudo Town, and absolutely no one knows why this is, least of all the Gorons. A throwaway line in the Japanese version implies that the Gerudo consider the Gorons honorary women.

* In ''WesternAnimation/TheOwlHouse'', it's revealed in the finale that [[spoiler:Titans]] are a single sex species who reproduce via [[spoiler:a TruleSingleParent both laying and fertilising an egg]].

** The Taresians of ''Series/StarTrekVoyager'' are a species consisting entirely of females that mate with males of other humanoid species to perpetuate themselves by implanting viruses in them that slowly turn them into male Taresians. As it turns out, the mating process (one male is given up to three females as his wives) is deadly toward males as [[DeathBySex they die after mating with their wives]]. Harry Kim was implanted with a virus that made him believe that he was secretly a Taresian, but eventually he and the Voyager crew find out the truth about the Taresians and rescue Kim before he became their next victim.

** Hags are all women. They mate with male humans (no mention is made of the various other sentient races) and typically [[DeathBySex subsequently kill and eat them]]. A female offspring becomes another Hag, while a male becaomes a Hagspawn, large, brutish creatures with no particular talent for magic that the Hags often abandon.

* PlayedForHorror in ''LightNovel/GoblinSlayer''. Goblins are an entirely male species, but there's also [[ExplosiveBreeder a serious number of them.]] The reason is because [[RapePillageAndBurn whenever they attack a settlement]], they will always try to kidnap females and imprison them in their nests to use them [[BabyFactory to breed.]] Every single Goblin out there is a ChildByRape ''by default.'' [[RapeIsASpecialKindOfEvil And that's only when they feel practical about it. Other times, they do it for the sake of]] ColdBloodedTorture.
* {{Amazon|ianBeauty}}s in ''LightNovel/IsItWrongToTryToPickUpGirlsInADungeon'' is a female-only race. They're cross-fertile with all mortals, but will only give birth to Amazons.
* PlayedForLaughs in ''LightNovel/KonoSuba'' with the [[OurOrcsAreDifferent Orcs]]. Konosuba orcs are a race of [[BrawnHilda muscular]] [[PigMan (porcine)]] [[BrawnHilda women]] who rely on men from other species to reproduce. The males of the species were wiped out and on the rare occasion one is born they're usually [[OutWithABang "overworked" to death]] before reaching sexual maturity. In their first appearance a mob of them chase Kazuma down and attempt to mate with him [[BlackComedyRape against his will]].

** Nymphs have NoBiologicalSex and cannot reproduce, but they are all created with a feminine appearance and are referred to by she/her pronouns by default. They can be female-to-male transgender or nonbinary, however.
** All arachne are female. They reproduce by mating with male silkbeasts.
** All skorpius are male. They reproduce by kidnapping women and impregnating them with their venom.

* There is no gender in ''VideoGame/{{Minecraft}}''. Any two individuals of a species can reproduce together, and in some races all members have female traits (all chickens lay eggs, [[AnimalGenderBender despite having rooster waddles]], and all cows give milk).

* All the elk in ''VideoGame/RedDeadRedemption'' are male, judging by the fact that they all have antlers and that only male elk have antlers. Averted with all the other animals though, even the deer.

* While this is not true in all ''Franchise/{{Transformers}}'' comics, some (especially those written by Simon Furman) display the Transformer race as free of gender, with the only "females" being failed alterations or side projects. While this makes sense as they are sexless robots, it's noteworthy that they all look and act "male". This is because the fandom is male-directed.

* The Hutts of ''Franchise/StarWars'' are [[{{Hermaphrodite}} hermaphroditic]], but as a cultural thing, they alternate gender terminology between the periods when they are capable of reproduction and when they are not (as a result, we could consider them an entire ''genderfluid'' race). At least, that was the case in the ''Franchise/StarWarsLegends'' continuity. The new ExpandedUniverse has made them dual sexed again, without the gender switching.

** The {{golem}}s, being created beings, are genderless. Until ''Literature/GoingPostal'', when one of them gets named "Gladys" so the postmistress doesn't object to her cleaning the ladies' privies. Since golems basically believe what they've been told to, Gladys is subsequently female, and people think of her as such. (And in ''Literature/MakingMoney'', Moist notes that, somehow, this seems to make the "default" golems male.)

** The same movie presents [[OurOrcsAreDifferent the Uruk-Hai]] as all-male and literally being spawned fully formed from mud pits.

* The subject of whether angels are all male in ''Literature/TheBible'' has been subject to debate. The Bible itself never says that angels are all male, but this is assumed to be the case due all named angels having male forms of their names (For example, Michael and Gabriel) as well as male pronouns being exclusively used for angels. Some interpret "the sons of God" having [[{{Nephilim}} children by women]] as meaning angels who ''did'' have sex (and so presumably bodies, unless this involves [[DemonicPossession possessing humans]]) while some apocrypha (like the Book of Enoch) supports the idea. Another line of thought is that angels are [[NoBiologicalSex genderless and sexless]], because they exist on a different plane than humans and thus cannot be perceived as being the same as us, with this supposedly being supported by the statement that angels in heaven did not marry. That being said, angels being genderless is never indicated in the Bible despite being a popular interpretation. Regardless, this hasn't stopped the depiction of female angels in artwork, and even the named archangels themselves have been subject to some gender-bending in media.

** In 2nd Edition ''AD&D'', the standard version of the minotaur is an all-male race. New minotaurs come into being when a human male is cursed to become one by the gods, or when a minotaur abducts and impregnates a human woman. Note that this only applied to the "default" version, and minotaurs from specific game-settings such as ''Literature/{{Dragonlance}}'' did come in two genders. (4th Edition averts the trope altogether.)

** ''TabletopGame/Warhammer40000'' The Orks in (and possibly the Orcs in ''TabletopGame/{{Warhammer}}'') seem to be all ridiculously masculine, early [[RetCon non-canonical]] references to female Orks notwithstanding; however, since [=Wh40k=] Orks are actually a hybridization of mammal and ''fungus'' that reproduce via spores, attempting to assign a gender to them is basically an exercise in futility.

** Chaos Daemons, aside those of Slaanesh, are generally mono-gendered due to the fact that they're fragment representations of their respective Chaos Gods. This is because rather than being born biologically, they're created via other methods (Khornate and Tzeentchan Daemons are usually created by actions of their respective gods, while Plaguebearers are spawned from the departed souls of people who die from Nurgle's plagues). Slaanesh is a special case because he/she/it and all of his/her/it's daemons tend to switch pronouns depending on who you ask (Eldar exclusively refer to Slaaneshi daemons with female pronouns) and technically Slaanesh is a hermaphrodite.

* Archers from ''Franchise/{{Disgaea}}'' were always female and created by their WorldTree until the [[VideoGame/Disgaea3AbsenceOfJustice third game]], but the males were referred to as "rangers" instead. Then there are the succubi and catgirls. Since each class is gender-specific, there are duplicate [[SpearCounterpart male]] and [[DistaffCounterpart female]] counterparts of most classes. Since the "monster" classes are all gender-specific, as well, but monsters are, through Mediators, capable of marrying and even producing offspring, it's safe to assume that GenderEqualsBreed.

** The asari are a single sexed race that at least looks entirely female, who can reproduce either through parthenogenesis or via some complex partially psychic reproduction with each other[[note]]Though an odd bit of gender diversity occurs in this situation: The asari that gave birth is the mother while the other parent is considered to be the father, even though both appear to be women from an outsider's perspective.[[/note]]. Of course, they're also among the wisest and most ancient races in the galaxy, powerful users of biotic techniques, and the founders of the Citadel Council, which governs 80% of known space. But the player is likely to be more interested in their ability to 'merge' with anyone, regardless of race and gender. The asari even have a [[FantasticRacism Fantastic Self-Racism]] against asari who join with other asari. Partly because the race feels that nothing new is gained from merging with other asari, and partly because only "pureblooded" asari can be born with a genetic birth defect that causes them to be sterile, kill their partner when mating and quickly grow addicted to this sensation, basically becoming serial killer sex vampires. As such, everyone with this disorder is locked into convenes.

** The above quote is about the mogu, which had women at one point, but after their return to stone bodies and resulting lack of need for sexual reproduction, different sexes have been effectively outmoded and now all mogu appear "male". Lei Shen's Twin Consorts are rumored to be the only female-looking mogu in modern existence, and they suffer from the same HugeGuyTinyGirl syndrome as draenei, as a result of being literally built based on Lei Shen's personal specifications.

** Notably, ''VideoGame/{{Hearthstone}}'' has had some cards which featured the first depictions of previously unseen opposite sex depictions, such as female kobolds and satyrs, but this being a spin-off the canonicity is up in the air.

** Amazons have females and hermaphrodites. This is still a psychological gender, mind, since they still consider themselves female regardless. And the floppy bit is retractable.

* The Uryuoms in ''Webcomic/ElGoonishShive'' don't normally have genders, per se; any two Uryuoms can [[BizarreAlienBiology form an egg]] together, and they can use DNA from ''any'' living species to fertilize it, including {{Half Human Hybrid}}s of course (surprisingly, they ''aren't'' TheVirus, being relatively benign and somewhat whimsical). Those living on worlds where gendered species are dominant will generally adapt to the local customs; on Earth, they generally choose their own gender at some point, though some have one chosen for them by their parents.

* ''Webcomic/SchlockMercenary'': Carbo-silicate amorphs are, for all intents and purposes, a one gender race, and their reproduction process is explained in some detail in the comic, but is basically an interesting example of how parthenogenesis could produce offspring which differ from the parent. Technically they don't have a gender at all; Sergeant Schlock is referred to as "he", but Schlock is kind of an odd duck, in that he is A) actually kind of violent, and B) not the result of normal amorph reproduction, but the result of a critical failure in the process of amorph-to-amorph combat.

** In the Generation One cartoon, the Transformers were built as civilian and military hardware by the Quintessons for sale to other species. Though the Quints themselves are a one-gender race, they know and understand genders and built their products to appeal to their clients. Another thing to note is that for the longest time there were only female Autobots, the civilian line. Female Decepticons (the military line) were unheard of, and we only began seeing female villains in the sequel series ''WesternAnimation/BeastWars'' (Blackarachnia) and ''WesternAnimation/BeastMachines'' (Strika). Both of whom might have been Autobots or their descendants: Blackarachnia was a reprogrammed Maximal (Autobot descendant), and Strika is a revived spark, of unknown original side.

** The history of the Time Lords is, as with so many things, muddled. Technically, the second Gallifreyan we ever saw was female, although Susan wasn't even around when [[ContinuityDrift the concept of Time Lord even existed in the show]] — the Doctor was AmbiguouslyHuman during her tenure, and she was only said to be Gallifreyan retroactively. All the Time Lords seen after the introduction of the concept were male; even the name implies this. Creator/TomBaker assumed the Time Lords were all male and purposely played his Doctor a little awkward around women to give the impression, with the Sisterhood of Karn even coming across as the Time Lords' DistaffCounterpart. However, seventies ''Doctor Who'' was rather unclear as to whether "Time Lord" was the name of the race, or a title for members of the Chapters, which would make Tom's portrayal more of an unworldly Oxbridge don from the days when women weren't allowed on campus except as housekeeping staff. Regardless, the introduction of Romana in 1978 removed this assumption, and several Time Ladies have appeared since. In fact, with the Master becoming the Mistress (and the General in [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]], and now Creator/JodieWhittaker) it has been established that Time Lords(/Ladies) can change sex when regenerating. So they're not so much a one-gender race as an all-genderfluid one.

Note that the name of the species implies this. Tom Baker even assumed the Time Lords were all male and purposely played his Doctor a little awkward around women to give the impression. Of course, the addition of a Time Lady character in the late 70s removed this assumption.

* ''Literature/{{Animorphs}}'': The Hork-Bajir are originally seen this way, the only (externally noticeable) difference being the females have one less facial horn than the males (the free Hork-Bajir who relates this says that there are other differences as well, but refuses to share them).

* All of the talking anthropomorphic dogs in ''WesternAnimation/FamilyGuy'' appear to be male.
** And can even [[spoiler: interbreed with human women, which oddly enough, can result in fully-human offspring.]]
** However, after sixteen seasons, this is finally subverted in "[[Recap/FamilyGuyS16E10BoyDogMeetsGirlDog Boy (Dog) Meets Girl (Dog)]]", where Ellie is introduced as the first female talking dog.

* Subverted with the Irkens in ''WesternAnimation/InvaderZim''. They appear to be a race of generic ant-like aliens, but there are a few with distinctly feminine TertiarySexualCharacteristics (long eyelashes, curly antennae). The Irken's actual existence and sentience is tied to their PAK so presumably the meat-puppet they decide to use for a body is their choice.

* Subverted in ''WesternAnimation/VoltronLegendaryDefender''. The Galra initially appear to be an all-male race, but as time goes on more female Galra pop up, [[spoiler: with one of them even being the mother of one of the main characters]].

* ''Literature/AncillaryJustice'': Played with, with [[TheEmpire the Radch]] being a One Gender Society. While the people are physically ordinary humans with two sexes, the Radchaai make very little distinction between them, with fashions, social opportunities, and everything else being equally applicable to both sexes. The Radchaai language doesn't even have pronouns to differentiate between them, with everyone defaulting to female, and their society is completely egalitarian with jobs determined by a standardized test called the Aptitudes that are taken sometime before adulthood. Breq often laments about the difficulty of having to decide which pronoun to use to keep from looking foolish and how relieving not having to worry about it is after returning to Radch space.

* The varl in ''VideoGame/TheBannerSaga'' are a species of [[HornyVikings horned]] giants with seemingly limitless natural lifespans, each of whom otherwise looks exactly like a human man. Every varl was personally created by the [[Gotterdammerung now-dead]] god Hadrborg in an attempt to one-up the [[TopGod Loom-mother's]] creation of humanity, but since Hadrborg didn't create any varl women, no new varl have been "born" in the century since the gods' demise. While they still number in the tens of thousands, their warrior ethos is slowly driving them extinct.

* The Namekians of ''Franchise/DragonBall''. [[WordofGod As described by]] [[Creator/AkiraToriyama Akira Toriyama]], Namekians are designed after slugs, and in-show they reproduce asexually (by laying eggs with their mouth). That said, their secondary sexual characteristics are distinctly male (see the fellow in the moustache in the picture above).

* The [[ProudWarriorRaceGuy M'Laks]] from ''Literature/SpaceCaptainSmith'' have NoBiologicalSex, but all identify as male. They reproduce by vomiting up a bucketload of frogspawn, which grow into froglike juveniles and eventually humanoid adults. As all offspring are genetically identical to their fathers, M'Lak ensure diversity by deliberately exposing infants to high levels of radiation to cause mutations.
