Find this concept weird? Danny DeVito does too.
Amy, isn't it wonderful? I'm pregnant! Amy:
Yes it's... great. A great miracle. Leela:
And not one of those bogus everyday miracles like a sunrise. [beat] Aren't you a male?
, "Kif Gets Knocked Up a Notch"
A male character gets pregnant through Functional Magic
, weird science
, Bizarre Alien Biology
, body swapping
, actually being a seahorse
, or just plain bad writing. Usually played for laughs, but it can be done seriously or even tragically, especially when it's from a Face Full of Alien Wing-Wong
Especially common in fanfic
. The "MPreg" story is usually considered one of the
scourges of fan writing, second only to Mary Sue
, because it is done ridiculously often and the quality is usually even worse than normal badfics
. It is often given no more explanation
than The Power of Love overcoming fundamental biology
. But then, do you really
want to know which lower orifice the baby came out of? (Fanfic criticism circles describe such offspring as "ass-babies
". Use the term with care around mpreg writers, who can get butthurt
Sometimes, MPreg is justified when the action takes place in the future or if the protagonists are aliens (especially if they are hermaphrodites
). Or if it's somehow in canon. Regardless of how it comes about, though, fanfic with this often turns into Kidfic
In case you missed that class in Biology, the trope name comes from the fact that male seahorses have an egg pouch. In it, they receive and fertilize the eggs of their mates, and carry them to term. Not quite the same as a mammalian pregnancy (or the few fish and reptiles that birth live young), but it certainly appears as such to human eyes, especially when the young leave the pouch.
This is theoretically
possible in real life. A Scientist
was able to implant an embryo in the abdominal wall of a male baboon, and others report that it is indeed possible to get a man pregnant if the embryo is planted at the proper spot, but only if the man is pumped full of pregnancy hormones. The embryo creates its own placenta
, it turns out.note
Unfortunately, the abdominal wall is not designed to detach from the placenta, resulting in massive bloody injury
. There's also no obvious route of exit, and the baby would presumably have to be surgically removed. At any rate, male volunteers, not wanting to risk their lives on such a venture, have not proven common.
May involve Bizarre Alien Biology
and Bizarre Sexual Dimorphism
. If the other parent is also male, you've got Homosexual Reproduction
. Can be Body Horror
for men. Ladies, we respect you greatly for doing this for the species; please don't laugh too hard at how much this can freak us out. See also Chest Burster
and Ass Shove
for the potential non-C-section routes of exit. If the setting permits, male-male reproduction is best achieved with a Uterine Replicator
Probably the most understandable reason to say "But I Can't Be Pregnant!
" If the character actually is female (or at least has a uterus
), that's Your Tomcat Is Pregnant

- A Dairy Queen ad ran in 2008 depicting a young couple enjoying their ice cream and fantasizing about the future. The man imagines that he is blessed with a son. The women imagines she is the one holding the video camera while the man gives birth, screaming at her "you did this to me!"
- The official Catholic stance on Family Planning (or, "the rhythm method") vs Birth Control has inspired an ad featuring Pope John Paul II, who is rubbing his very prominent belly and grinning, underneath is written, "Would he be more careful if it was him that got pregnant?"
- This◊ cinema board (reading "Harry Potter Knocked Up Evan Almighty), unintentionally so.
- Yoplait once ran an ad campaign where eating the yogurt gave the consumer a vision of their greatest desire. For one woman, it was her husband giving birth (apparently without pain meds), screaming and cursing about how she did this to him.
- This commercial for Dream Ice Cream, via Imagine Spot.
- An American broadcast ad for the PlayStation version of The Game of LIFE had a male player excitedly landing on the square that tells you you're having a baby — and appearing heavily pregnant as a result. He was also wearing a pink shirt.
- This Argos advert for baby furniture. Justified Trope, in the case - the pregnant guy is an alien.
- The city of Chicago ran a teen pregnancy prevention campaign that ran on this trope to raise social awareness and spark debate, depicting pregnant teenage boys with the taglines "Unexpected? Most teen pregnancies are." or "It shouldn't be any less disturbing when it's a girl."
Anime & Manga
- In Fullmetal Alchemist, Father, mid-way through consuming Hohenheim, appears to be pregnant, with parts of Hohenheim sticking out of him. It's not any better when Hohenheim completely disappears into Father, making Father look grossly overweight.
- In Genesis of Aquarion, the primary villain ends up pregnant after the 'dance of feathers', with the protagonist... and then later miscarries, though this is the least strange plot point in this series.
- In Futaba-kun Change, the main character learns that he and his entire family are all Gender Benders triggered by sexual arousal, meaning that the person he's always thought of as his father is actually his mother in the purely technical (or biological) sense. Naturally he finds this revelation deeply disturbing.
- Patarillo's Bishounen Maraich is somehow able to become pregnant twice despite being 100% male and human.
- This is more or less what the entire plot of the manga Sex Pistols (released in English as Love Pistols) is... a bunch of somewhat-human guys and girls with animal spirits trying to breed with other guys and girls, where Homosexual Reproduction is common place and men can become pregnant due to their unique physiology and this one ordinary teenage boy gets thrown into this mess and...Uh... Imagine Fruits Basket on amphetamines, throw some viagra and Mood Whiplash in and you're somewhere in the right ballpark. If you're on acid.
- Played for laughs in CLAMP's Muri Kuri.
- In the Animal X series (Animal X: Daichi no Okite, Animal X: Aragami no Ichizoku, Animal X: Genshi Sairai) made by Sugimoto Ami in 1990, Yuuji, one of the main characters, a gender bender, has the ability to get pregnant and does several times through the series. The series is not only very mature, but provides an even more in depth view of MPREG than even Sex Pistols/Love Pistols.
- Humorously addressed in the Full Metal Panic! TSR comedy radio show. Yes, Full Metal Panic of all series. Gauron tries to get Sousuke to admit that he wants to bear his children. Even funnier is the fact that Sousuke thinks it's possible.
- Kämpfer may or may not have a really weird subversion. At the end of episode 12, a female adult Natsuru is seen reading a Christmas story to a little girl, her husband comes over... and it's revealed to be male Natsuru. With a mustache. Wut.
- A pseudo-example happens in Franken Fran. An experimental stem cell surgery caused a cardinal's brain to develop into a fully developed infant. The cardinal later convinces Fran to remove the baby so he can take his secret past life to his grave. The baby was then given to the nuns that tried to exorcise the cardinal.
- A scene in the epilogue of ˝ Prince has Gui and Lan deciding to have a baby. Because Lan can't stand pain and doesn't want to have to go through giving birth, Gui ends up pregnant with her child.
- Happens to Panda in Gokudo.
- In Haiyore! Nyarko-san, Cuuko eventually develops some feelings for Mahiro, and decides she, Nyarko, and Mahiro should be a family, with Mahiro bearing her child. Mahiro is freaked out, not just for the obvious reasons, but because Cuuko is simply the human form of a Lovecraftian alien being and thus might actually be able to make it happen.
- Yukari and Sora from Family Compo are a transsexual woman and man respectively. Sora gave birth to their now-adult daughter Shion, though he was initially reluctant.
- Spider-Man once turned into a real giant spider, got pregnant, died and finally gave birth to himself in human form with all of his memories intact and new powers. This story has not been referenced much since.
- The Infinity Gauntlet series:
- Adam Warlock goes through a Journey to the Center of the Mind Vision Quest in which he is turned female, culminating in his/her giving birth.
- Adam Warlock's female counterpart, Kismet, was artificially created by The Enclave, a group of mad scientists dedicated to creating the perfect being, as a male named Paragon. When Paragon learned of Adam's existence, he decided to transform himself into a female in order to mate with Adam and give birth to a perfect child. Adam wasn't responsive to the idea, so Kismet went in search of another possible mate. In an alternate timeline, she and Quasar (Wendell Vaughn) have a son named Starhawk. Oddly enough, Starhawk ended up sharing a body with his wife, Aleta.
- In the far future of Grendel, planetary emperor Orion Assante must carry his heir to term himself, as his wife's health is too fragile to handle a pregnancy. Justified in that futuristic medicine allows for surgical implantation of the embryo, as well as a Caesarian birth. Years later, male pregnancy is still kept as a sacred tradition to birth new rulers.
- Purple Planet Eater Galactus was recently revealed to have a daughter, Galacta, which led to some rife speculation about who her mom was. Turns out it was also Galactus. He also specifies that he was pregnant with her.
- The Fabulous Furry Freak Brothers - in one story, Phineas gets his girlfriend pregnant - they're both pleased with the news, but her father is definitely not, and demands she get an abortion. Phineas takes her to a Mad Scientist friend who suggests an alternative, and transplants the fetus into Phineas. After that things start to get weird.
- The entire plot of the comic book Als Baby. In the near future, Al Bestardi (also known as Al the Beast) is the number one enforcer for Don Luigi, an aging mobster who rules Chicago, and who gave Al permission to marry his only daughter, Velma. Luigi decides that he needs a grandchild in order to carry on his legacy. Unfortunately for Al, Velma refuses to get pregnant, as it would interfere with her career as a torch singer - and as it happens, male pregnancy is now medically possible via surgery...I think we all know where this is going.
Fanfiction based on Anime & Manga
- In the Hellsing fanfic The Way To An Heir, Alucard attempts to impregnate Integra with a spell, but ends up getting himself pregnant. While somewhat bizarre, it actually makes sense (Girlycard duh!)
- Only slightly less disturbing are slash fics that use male pregnancy as a natural consequence of gay sex.
- In the Gundam Wing Fandom:
- This happens so often to poor Duo Maxwell that you could probably find such a fic in five random searches.
- Heero is popular too, by rape at times, since he was experimented on and all.
- Quatre sometimes gets pregnant too.
- Mpreg is very popular in Axis Powers Hetalia, as states and provinces are often depicted as the children of nations. However, if you applied a bit of Fridge Logic to this, you would realize that a country's states are actually parts of their physical body, such as America's ahoge as Nantucket, and Korea's as Seoul, so the entire premise is built upon the MST3K Mantra.
- Except that the countries are all anthropomorphic personifications, so literal "body parts equated to country geography" doesn't really work.
- Poor America seems to suffer the most from this, with a entire livejournal community dedicated to his pregnancies. Such is the popularity of giving America the seahorse treatment that someone actually did a chart detailing the most likely fathers of the respective states with comments on the circumstances of their conception (for instance, Alaska is "Most likely to have resulted from hate-sex").
- There is the canon presence of Hong Kong, a city in China, who's sometimes taken by the fandom to be China and England's love child. And Cyprus, another official (if yet-to-appear-in-canon) character, is often similarly viewed as Turkey and Greece's love/hate child.
- The YuYu Hakusho fanfic Cockroach by Thoth Moon is a deconstruction of this trope. It features Sensui and Itsuki, the last two guys in YYH who should be having a baby and is presented as a very scary Body Horror story, with What Measure Is a Non-Human? added for good measure because of the characters involved. After numerous failed abortion attempts, Itsuki gives birth through a very painful dimensional rift between his legs. So painful, in fact, that he passes out for a few hours during labor in the bathtub. They end up keeping the dead baby in their freezer after Sensui's "Kazuya" personality slaughters it.
- Fruits Basket slash authors love doing this to Hatori, who transforms into a seahorse if hugged by a woman.
- A popular element of Pet Shop of Horrors fanfiction. Guaranteed to be a FOURTH of the total fanfics available of this fandom. Possibly justified with Count D, as he is not human... But Leon?!
- There are a lot of Dragon Ball Z fanfics that have either Goku or Vegeta pregnant with each other's baby. It's become widely believed by fans that male Saiyans are capable of impregnating each other, though opinions are split on whether this applies to all male Saiyans or only the "lower-tier" ones.
- There's a XxxHOLiC fanfiction that can be found here that has Doumeki getting pregnant after eating a magic donut. Hilarity Ensues.
- Poor, poor Edward Elric. So many fanfics have this already-traumatized Child Soldier get pregnant and suffer Badass Decay every time he turns around. The other father is most commonly his commanding officer who is fourteen years older than him, except for that time Envy was the "mom."
- In the Naruto fandom:
- Naruto would get impregnated (usually because of Sasuke) because of several reasons; the Kyuubi is a female (even though it is just a mass of malevolent chakra with no real gender), the "fact" that demons can reproduce regardless of gender and this was carried on into Naruto (or other jinchuuriki like Gaara, opening up a whole new can of worms), there is a jutsu that enables males to get pregnant, Sexy no Jutsu somehow alters the user's entire biology, or Orochimaru is being his usual sick self and experimented on male pregnancies for some completely unknown reason. Take your pick.
- Beyond all this, it somewhat ties into kitsune behaviour, as they were known to pull such shenanigans.
- In the rare chance that Sasuke gets pregnant (in the NaruSasu pairings) it's usually because of the Kyuubi's chakra that causes his pregnancy. That or Orochimaru/Kabuto did some rather interesting experiments on poor Sasuke, leading him impregnated by everyone and anyone, including his own brother. Occasionally it's Sexy no Jutsu gone wrong, but since he has the Sharingan wouldn't he just be able to perfectly copy the jutsu?
The second part of Sasuke's goal is to repopulate the Uchiha clan... but in Self Reliance (Original story deleted, archived version in HTML and PDF format available)
, he doesn't trust any females he knows to carry his child. So he decides the logical course of action is to carry the child himself.
Fanfiction based on Comic Books
- This Fairy Tail fanfic, which manages to keep everyone in character for roughly three chapters before slowly derailing (though one character does have a justified, plot relevant character change).
- There's a Suzumiya Haruhi No Yuutsu fic which involves a rare heterosexual version. What happens when a couple wants a kid, but the girl doesn't want to carry a baby? Usually, adoption or nothing. However, when said girl is a Reality Warper...
- This video features a couple of fangirls trying to get Johnny Yong Bosch to sign Bleach M-preg fanart.
- This Bleach Mpreg fic actually does some rationalizing... a bit. The author fully admits that it isn't really good science but that it works for her. She then takes it Up to Eleven by having the character give birth... in enemy territory.
- Parodied in the Code Geass fanfic Ambiguous wherein Suzaku mysteriously gets pregnant by Lelouch. The natural way. The biological impossibility of this is lampshaded, amongst other improbabilities found in Mpreg fanfics such as the credibility of the doctor to reach such a conclusion, and male seahorses.
- Done many times in Yu-Gi-Oh! GX Fanfic. Usually Justified by Jaden/Judai's fusion with Yubel granting him (some of) the necessary equipment.
- There is an entire Tumblr dedicated to the idea that Vash and Knives get pregnant by Wolfwood and Legato, respectively (with the resulting offspring having their own RP blogs). It's explained that since Vash and Knives are plants they're not "male" in the truest sense of the word.
Fanfiction based on Film
- Based on a recent arc in the Mighty Avengers where Tony Stark was turned into a woman temporarily; a mpreg fic called Moth has been written.
- A decent Affectionate Parody of the genre is That Damn MPreg.
- It features the Young Avengers characters Wiccan and Hulkling. Oddly enough, these two characters are relatively easy to explain away in terms of an MPreg: Hulkling is a shapeshifter, and Wiccan can alter reality in a limited fashion (by way of example, the character who he is based off of, Scarlet Witch, got pregnant off a robot, which is on a level of insanity equal to M Preg).
- Actually, wiccan has been revealed to be the lost son of the Scarlet Witch, as is Speed, so he has similar powers to his mother, like his twin has similar powers to their uncle.
- The universe also has Grace Summers, the daughter of Sean Cassidy-Guthrie and Christian Summers. Carried to term by Christian though the circumstances regarding what allowed the pregnancy remains a mystery.
- The two-part fic, X-men: Sabertooth Mpreg , puts an interesting spin on the genre. Unlike most other Mpreg fics, the characters aren’t turned into Out of Character woobies or softies, and the story is far from your typical fluffy kid fic.
Fanfiction based on Literature
- This extremely frightening fic has the Joker knocking up Scarecrow. It's Nolanverse ... if that helps.
- Naturally, the Parody Fic series Sith Academy had a couple of things to say on this topic. In the first, no actual M Preg takes place; it is simply that an addled Yaddle assumes that all the patients for her free clinic are pregnant. The follow up to this involves Bizarre Alien Biology in the otherwise human-seeming Jon-Tra Volta, and a wild night with a wookie.
- Used in the The Rocky Horror Picture Show fanfic Parental Guidance in which it's Dr. Frank N. Furter who ends up pregnant. Most of the questionable aspects of Mpreg are Handwaved/explained via Bizarre Alien Biology. Long story short, Frank becomes pregnant (the "father" is yet to be revealed), grows really fat, and, instead of giving birth to live young (which is the standard for most Mpreg fics), ends up laying a clutch of eggs.
- X-Men:First Class, wherein just one hilarious macro image◊ launched a wave of fanfics wherein Erik impregnates Charles. The science is usually handwaved using the idea of Charles simply having a second mutation.
- It's very common in the Thor fandom to have fanart and fanfiction of pregnant Loki. Justified because Norse Mythology has Loki being pregnant several times, and a lot of the pieces are actually retellings of those stories.
- Partly justified. Fans cheerfully ignore the part where the Loki of Norse myths was in some sort of female form the times he bore children.
- Delivered From Frollo has Chernabog (from Fantasia) impregnating Frollo (from The Hunchback of Notre Dame). The author explains it by saying that they "no longer have physical bodies as we understand them," as the story does take place in the Underworld.
- Harry Potter fanfic writers love this to death. At least the unpredictably of magic gives it a fair reason/excuse. Most of the time. It's perfectly common to see Harry knocked up with twins, usually, from Draco or Snape, or anyone really.
- A Snape/Lupin mpreg story can be read here It's not a slash story and surprisingly well written, despite the first chapter being a bit OOC.
- There was a Harry Potter fanfiction in which Ron and Draco had a fertility potion spilled on them during a private detention in Snape's dungeon, leading to Ron becoming pregnant by Draco, who left him, so Ron ran off to have sex with Harry, who dumped him after finding out Ron had slept with Draco; then Ron started going out with Gary Stu!Neville, who just so happened to have a crush on Blaise, leading to Ron and Neville making out in front of Blaise and Draco in order to make them jealous, which preceded Neville finding out about Ron's pregnancy and declaring that he wanted to be the baby's father, while Mentor!Snape helped them along. There wasn't a female character in the fic.
- There is a fanfic where Harry gives birth to a kitten, after having gay sex with Voldemort while transmuted. Couldn't make this up if I tried, people.
- This script fic parodies nearly every Harry Potter Mpreg fic ever.
- My Immortal unintentionally references this in the line where Harry fends off two peeping toms by yelling "ABRA KEDAVRA!" and "pointing his womb".
- A Most Unlikely Family is a Harry Potter-Discworld crossover, in which Neville finds himself in Ankh-Morpork, pregnant with Harry's baby. Apparently the magical accident responsible gave him a womb but not a vagina.note Sadly the mother didn't survive, but here's something to ponder: which Discworld character kinda resembles both Harry and Neville?
Fanfiction based on Live Action TV
- The Lord of the Rings:
- The creators of Bag Enders are also known for comedic mpreg, and described it thus in their "Horrifically Honest Guide to Fanfiction Terms": "Since there exists no fanfic genre of ‘M-PMT’ or ‘M-bloody awful period pain’, this is one outlet to make your characters get all the suffering of being female with none of the benefits. Bwahahaahahaa!"
- Feel free to alternate between cringing and cracking up while reading the ultimate Legolas/Aragorn. "My assumption is correct: your birth canal has formed." NO. WORDS.
- One Redwall fanfic unintentionally references this. The Mary Sue heroine's sidekick was supposedly the daughter of the canon characters Brome and Keyla. Brome is a male mouse, and Keyla, despite the Gender-Blender Name, is a male otter. As they didn't appear in the fic, one can only assume the author forgot the gender and/or species of at least one of them, but the mental image wasn't fun. Unless you're into that.
- And when Gaius reveals that there's something worse
Gaius: "It's yours, Sire."
- Arthur is understandably horrified... Considering that they've never had sex.
Fanfiction based on Music
- An extremely long American Idol fanfic titled Cambios narrates the entire life chronicles of David Cook and David Archuleta's kids, beginning with their daughter Reyna who was conceived accidentally during their time at AI (meaning Archie was 16, people!), with very little explanation (something about some guys being able to get pregnant). The two go on to have four more children, and Archie looks 'exactly the same' a decade later. It ends with Reyna auditioning for American Idol, and the judges proceed to tell her that she looks like both Archie and Cook, and her singing voice is a mixture of the two.
- Very common in the Glee fandom with Kurt/Blaine shippers. Finn supossedly utters the line 'don't get my baby brother pregnant' a lot.
- Numerous Sherlock fanfics. Usually Sherlock/John. By far the weirdest one is this one.
- Given that the favorite characters of most Stargate Atlantis fans are McKay, Sheppard and their kind but harried medical support Dr. Beckett, that the favorite fanfic genre (by far) is Sheppard / McKay slash usually involving Aliens Made Them Do It, and that the show's canon features entirely unpredictable Ancient technology that is triggered into activity by especially Sheppard's genetic make-up and that they spend a lot of time actively searching for and experimenting with, the M-Preg practically writes itself. Usually it's McKay who ends up getting knocked up, apparently mainly because he's a neurotic hypochondriac who hates kids. Fanfic writers are cruel.
Fanfiction based on Video Games
Fanfiction based on Webcomics
- There's a story where Sam Totman gets "womb implant" surgery while drunk in Paris. And it will never stop being funny. Ever.
- Another one (by the same author) where a hermaphroditic Fred Leclercq conceives sextuplets after being raped by one of his bandmates from Maladaptive. It's significantly less funny.
- There's a Beatles mpreg fic in which Paul gets pregnant.
- As if twincest wasn't squick enough, many Tokio Hotel fanfics involve Tom impregnating Bill somehow.
- At least one person has done fanart and fanfic for The Who that involves Pete Townshend knocking up Roger Daltrey.
Fanfiction based on Web Original
Fanfiction based on Western Animation
- Toby "Radiation" Fox, one of the composers for Homestuck, wrote "I'm Having A Baby And The Baby Is You", a deliberately So Bad, It's Good "Rock Opera" about Dave giving birth to John (a thirteen-year-old John is also there at the time and has to help deliver the baby). This was written to protest a new forum rule saying that no depictions in fanfic or fanart of the child characters may show sex or imply sex has happened, including (specifically) pregnancy. While it's completely stupid, the mods clamp down pretty hard on any discussion on it at all.
- Outside this, Eridan is the most popular target of mpreg, the trend originating from the fact that his lusus is a seahorse, although canonically no trolls of any gender can get pregnant. A common trope is the idea that his Skunk Stripe is a natural trait signifying that he can be impregnated.
- One of the plot devices in the Crack Pairing thread in the Order of the Stick forums. It doesn't get used very often, though, but when it does, it is hilarious.
- Even Sweet Bro and Hella Jeff is not immune. Definitely Played for Laughs and Fan Disservice.
- There's male pregnancy as horror fanfic. There is a Teen Titans animated series fic where Robin was used (quite unwillingly) for a Mad Science experiment...and impregnated with several hundred sea monster embryos. Monsters in the Closet - it can be found here in all its debatably wonderful, horrific glory.
- The Mind of a Hero. The circumstances behind it, while Weird Science, are far from happy. It involves an odd device to bring Danny's inner shadow forth... and his first words: "Why my mother?!"
- Transformers Mpreg is fairly common, starting with the fact that you can count the number of females in G1 on one hand but the number of males ranks in the thousands, and ending with them being robots. The tougher question should be how they can get pregnant.
- Some Avatar: The Last Airbender slash writers have the disturbing tendency to get Zuko knocked up, usually with Jet's spawn. Worse, one particular author wrote two fics on the subject using the dreaded Rape Is Love plot device (as if Zuko hasn't already suffered enough in canon, jeez). But to be fair to her, she did at least give semi-plausible explanations for Zuko's ability to carry children.
- This Invader Zim fanfic shows an interesting take on this trope.
- Fanfiction which is based on an Alpha/Beta/Omega hierarchy in general (such as a lot of Werewolf AU fic) will often have omega males being capable of being impregnated and giving birth.
- The Arnold Schwarzenegger/Danny DeVito vehicle Junior, in which Arnold plays a scientist who is willing to get pregnant. The movie is a comedy, but the pregnancy is played surprisingly seriously here, leading to some emotional development in Arnold's character.
- Rabbit Test, a 1978 film directed by Joan Rivers and starring Billy Crystal.
- A slightly squickier variant happens in the Alien movies, wherein people of any gender and presumably any species can be impregnated with baby aliens. The first victim in the series is, notably, male. In fact, it was John Hurt.
- John Hurt was alien-pregnant again in Spaceballs.
- Louis Gossett Jr. is a pregnant
male hermaphroditic and naturally parthenogenetic alien in Enemy Mine.
- The 1940 Gender Bender comedy Turnabout ends with a husband and wife seemingly returning back to normal after spending most of the film in each other's bodies...until the ancient Indian idol that made the initial switch confesses that he's screwed up and informs the husband that he's now pregnant.
- It happens, in an extreme Body Horror way, to a few of the brainwashed townspeople in Slither. It almost happens to the main character but he escapes it due to a technicality.
- Male Kabiijians in Evil Alien Conquerors.
- The Immaculate Conception of Little Dizzle, wherein a group of janitors become guinea pigs for a new type of self-warming cookie. The chemicals used to create said cookie cause a sort of fishlike creature to grow in the males who eat them, which are later "birthed" through the anus.
- This short, produced by the Biola University Guerrilla Film Initiative.
- One of the posters for A Nightmare on Elm Street 5: The Dream Child depicts Freddy Krueger this way◊. Lord of nightmares, indeed.
- In Alienable (2008), featuring Walter Koenig and Richard Hatch, combines the trope in question with a struggle for legal custody.
- Stingray Sam. The rich have only been having male children (via gender-decisive drugs) in order to perpetuate their dynasties and so are in danger of dying out. Doctors Fred and Edward come up with a solution by combining their DNA to create their son, Fredward. This leads to (another) Big Lipped Alligator Moment from our heroes, as they sing of this miraculous invention and all the ensuing names.
Fredrick and Edward had a son named Fredward, Max and Clark had a son named Mark, Aldo and Rex had a son named Alex (etc)
- In the direct-to-video Roy "Chubby" Brown vehicle UFO, Chubby unwittingly gets this done to him as a punishment for the lewd and sexist nature of his act (the alternative punishments being chemical castration, physical castration, or having his testicles beaten with a cricket bat and having a red-hot poker shoved in his anus). Part of the treatment involves his body being modified so that the child will be born through Chubby's backside, which goes From Bad to Worse when it's revealed that he'll get pregnant every year for thirty years, which will leave him with "an arsehole the size of the Grand Canyon" when all is said and done (though he ultimately only has to give birth once).
- This is discussed in Monty Pythons Life Of Brian:
"It's every man's right to have babies if he wants them."
"Right, but you don't have a womb! Where's the fetus going to gestate? You gonna keep it in a box?"
- This is practically the driving premise of Storm Constantine's Wraeththu novels, in which it is executed for entirely "straight" dramatic ends.
- In the Wild Cards series, Dr. Tachyon has his mind swapped by his Ax-Crazy grandson Blaise, who leaves him a teenaged girl's body. Blaise rapes her repeatedly, eventually getting her pregnant shortly before leaving Earth (with the girl trapped in Tachyon's original body in tow). By the time Tachyon has gotten back into his original body, s/he had not only given birth, but had gotten pregnant again.
- In the short story —All You Zombies— by Robert A. Heinlein, an intersex woman gives birth then gets a sex change and travels back in time and impregnates herself. By the end of the story the mother, father, baby, and narrator are all revealed to have been the same person. Aren't time travel loops fun?
- In the 15th book in The Dresden Files, Skin Game, Harry discovers that his "parasite" is actually a child conceived from Lash's sacrifice as an act of unconditional love. Given that the book is about robbing a near-impenetrable vault to steal from Hades' private treasury there are clear parallels between Dresden's mind-child and Athena, who burst, fully-formed, from Zeus' skull.
- Jack Chalker's transformation novels, such as the Well World series, often feature this happening to assorted characters, usually through Bizarre Alien Biology. One was even transformed into an actual seahorse. He didn't actually get pregnant, but the possibility was acknowleged.
- Done with the titular alien species in Chalker's Web of The Chozen: Female choz lay six eggs and both males and females incubate them in brood pouches. The sex of the offspring is determined by the sex of the incubating parent with the normal ratio being 2 males to 4 females. The hero of the story is the only male choz who produces female offspring.
- An Anne McCaffrey short story in which an alien prostitute impregnates half the male population of a small town. The title, A Horse From A Different Sea, references the seahorse analogy.
- An exceptionally icky example is present in Iain M. Banks' Excession. Given that people tend to live several centuries in the far future society portrayed, life-long monogamy is exceptionally unusual. A couple who plan to stick together that long can engage in a process that involves this trope in order to emphasize their co-dependence. A couple can impregnate each other in turn to give birth at the same timeexplanation in a process called Mutualling. In the specific example, the woman goes Ax-Crazy with a knife and kills her partner's fetus (also nearly killing her originally male partner) when the (then female) partner has an affair with another woman while pregnant. The partner changes back and leaves the woman while the woman goes nuts and stabilizes her pregnancy to remain pregnant for the rest of her life. This sequence of events so disturbs the AI of the colony ship they lived on at the time (which had watched and subtly intervened in the lives of millions of people who lived on it over its existence) that it resolves to fix their broken psyches as a personal preoccupation. The story ends “happily ever after” with the couple reconciled before once again going their own ways, the woman giving birth and then being allowed to raise the child she'd gestated for the last 20 years, and the partner (now male) gone off to become (physically) a member of a species of Straw Men.
- In The Fresco by Sheri S. Tepper, some aliens temporarily stranded on Earth pick on a group of powerful conservative American men to incubate their young, reasoning that since the men are opposed to abortion, they'll agree that it is their duty to help the aliens out. The men are not happy, especially when it turns out the young aliens will have to eat their way out of their bodies. The whole incident provides an anvilicious moral: don't force others to do what you aren't willing to do yourself.
- Parodied in the last A Series of Unfortunate Events book, where Count Olaf's ultimate disguise is of a pregnant woman. Even the people he's trying to fool think it's ridiculous.
- The Yilanč in Harry Harrison's West of Eden trilogy are one of the best uses of this in fiction. The race function in much the same way as seahorses. Few males survive more than three brutal pregnancies, and the society is dominated by females who keep the males solely as breeders (despite them being every bit as intelligent as the females).
- In Walter Jon Williams's novel Aristoi, the (male) protagonist's boyfriend voluntarily becomes pregnant with the protagonist's sperm, using the commonplace technology of the far future (it's so far in the future that people have godlike powers and can do anything).
- You can also get an implant that over several months gives you a complete and total sex change. Guys who want to experience pregnancy and birth as women can use these.
- Briefly mentioned in Diane Duane's High Wizardry.
- Occasionally mentioned in passing in some of S.L. Viehl's books; for example, a rumor circulates in Stardoc that Cherijo has impregnated Kao. And then, there's this exchange in Blade Dancer:
Thgill: I'd love to have your offspring. How about we get intoxicated, go back to my place, and you impregnate me?
Jory: Doesn't work that way with my kind, pal.
- One science-fiction story (the author of which clearly had issues with men) involved a matriarchal society in which males were implanted with embryos. The last third of the story was a graphic description of the baby tearing its way out of the male's body.
- In Cordwainer Smith's short story The Crime and the Glory of Commander Suzdal the once-human klopts reproduce by implanting a lump of cells in the gut and give birth by C-section. Plot of which can be found here.
- In The Stress of Her Regard, silicon-based vampiric lifeforms from Earth's primordial past are roused from torpor when one of them, resembling a small statue, is implanted in the body of a living man. To send them back into hibernation, the obstetrician protagonist must perform a forced Caesarian section to extract the statue (which has grown since the first surgery!).
- Mentioned offhandedly in Charles Stross' Iron Sunrise.
- In The Whims Of Creation, by Simon Hawke, the baby incubators on a generation starship are believed to have been compromised by a rogue computer program. Several characters speculate that any existing fetuses may have to be gestated the old-fashioned way for the first time in centuries. When a female character takes exception, her husband reminds her that technology has advanced far enough to allow him to do all the hard work. Although the incubator issue is resolved, the book ends with him giving birth to their daughter.
- In the William Schoell sci-fi/horror novel Dragon, several workers helping to uncover an ancient temple become sick and are taken to the local hospital. After doing exams, the stunned doctor declares that somehow, they're pregnant. It turns out this is one stage of the temple's secretly super-advanced defense system. The men are "pregnant" with hideous monstrosities which, like in Alien, burst out of them and proceed to kill everyone in the hospital.
- In a variant, the Thomas Disch short story "Emancipation" featured a man who gets surgically altered so he can breast-feed his child, in a future where gestation routinely occurs in People Jars. Counts as bad research since hormone treatments would be all that was necessary.
- In the Prince Roger series, the "women" of Marduk are by the strictest definition male. The "men" of the species have an organ which resembles human male genitalia, but it's actually an ovipositor. When a Mardukan man ovulates, he implants the ova into a woman, who fertilizes the egg and carries it to term.
- Stanley Pottinger's "The Fourth Procedure" features a VERY pro-life Strawman Politician being impregnated (very much against his will) by a VERY pro-choice surgeon.
- Mentioned in Lucian's True History. The people of the moon are a One-Gender Race (all males) and their sons grow inside the calves of the men.
- In Isaac Asimov's The Gods Themselves, the aliens have three sexes: Rationals, Emotionals and Parentals. While only the Emotionals are referred to as 'she', it's the Parentals, consistently referred to as 'he', that actually bear the children.
- Metaphorically present in Frankenstein. The process of creating each new artificial life takes the titular doctor the better part of a year, with the hardest labor coming near the end and leaving him mentally and physically exhausted. Does This Remind You of Anything?
- Stephen Colbert explains the seahorse in I Am America (And So Can You!) in his chapter on sex.
- Monkey, a comedic adaptation of the (very old) Chinese novel Journey to the West, has an episode where two of the main characters Zhu Bajie and Xuanzang unknowingly drink magical pregnancy inducing river water flowing through a town filled with nothing but women and Sun Wukong has to retrieve an antidote.
- Lister in Red Dwarf, through having sex with his counterpart from a gender-reversed Alternate Universe.
- In Alien Nation, Newcomer males have their children transferred into their bodies before they fully come to term, in a more literal seahorse-like way. While Tenctonese females incubate the pod until it is time for transfer, the males experience the majority of the pregnancy, including massive hormone changes, mood swings, sensitive nipples, nursing the pod, carrying the extra weight, and (the reeeeally fun part) the actual act of giving birth.
- Similarly seahorse-like, in Babylon 5, all Narn males have a pouch like that of an opossum or other marsupial, in which newborn babies are placed until they are old enough to go out into the world. Although this biological tidbit never factors into the plot of the series, G'Kar has been known to reference his own body part in unusual euphemisms and refers to some naďve Narns as pouchlings.
- Merton in Big Wolf on Campus after an alien abduction. He himself references Junior as part of his Once per Episode movie-buff routine, and then there's this shout out to Alien...
Merton: So, how do you think the baby will make its way into the world, my anatomy being a little different from the average child-bearer?
Alien: Are you familiar with the film Alien?
Merton: Are you kidding? The 1979 Ridley Scott classic, featuring Signourney Weaver in a career-defining role?
Merton: Oh! Remember the part where the alien bursts out of John Hurt's stomach? That was disgusting...you mean?
- Capt. Jack Harkness has a throwaway line in the first episode ("Everything Changes") of Torchwood "Oh well, at least I won't get pregnant, I'm never doing that again." Harkness' home era is the 51st century.
- In Star Trek: Enterprise, a particularly irresponsible Green-Skinned Space Babe assumes that the mpreg-inducing Green Rocks used by her people won't work on a human, and invites chief engineer Trip Tucker to play with their mind-linking capabilities. Her assumption proves wrong, and Hilarity Ensues. The Klingons were especially amused
- T'Pol later notes that Trip is the first Earthling male to get pregnant. He wasn't very happy. Considering how Earth governments probably banned all research into human augmentation and assisted reproduction in the post-Khan era, that's probably justified, despite Enterprise-era medical advances. When Trip later gets friendly with another alien babe, T'Pol is quick to bring this up once more.
- In the episode of Quantum Leap titled "8˝ Months", Sam leaps into a pregnant woman. Billie Jean Crockett is a pregnant teenager who will make the second biggest mistake of her life - giving her baby up for adoption - unless Sam, as Billie Jean, can convince someone to help her raise her child... before he goes into labor. Here's the specifics of how Sam becoming someone else works: Sam is always in his own body, and the person he swaps places with ends up back in the Waiting Room, though both people inhabit an outward aura of the other. After one leap where Al got droolingly distracted by Sam as a blonde bombshell, Project QL tweaked Al's "tuning" so that he would see through Sam's appearances from that point on. Hence why Al argues that Sam can't be pregnant — Sam is still technically in a man's body. Yet, Sam experiences several physical symptoms of pregnancy, including sudden nausea, cravings, backaches, swelling feet, hot flashes, frequent urination, bouts of sleepiness, and mood swings. He also insists that he felt the baby kick. When Sam goes into labor, the infant mysteriously vanishes from Billie Jean's womb in the future, while in the past the doctor is somehow able to see "a head of curls" and encourages Billie Jean to push. All the while, Sam is begging Al for help and screaming to "Get... it... out!"
- On The Cosby Show, Cliff once went through a pregnancy along with every other man in the cast — except Grandpa Huxtable, obviously, as he's old enough to have gone through man-o-pause — apparently due to some odd contamination in the water supply. The women were very sympathetic. Clair was wheeling him into the delivery room and Bill stopped to ask another man how it had gone - and, specifically, how much pain it had been. The description almost made Bill find the strength to run away. The show ended with Cliff delivering a six-foot sub sandwich and a two-litre bottle of coke; Denise's husband Martin delivered a toy sailboat. Theo, the unwed father, delivered a red convertible. Guess it was All Just a Dream.
- In an extremely short-lived NBC comedy from 1979 called Turnabout, Sharon Gless and John Schuck are a married couple whose bodies are switched (ŕ la Freaky Friday). In one episode, the husband, who is in the wife's body, thinks the body is pregnant. She/he isn't, but John Schuck gets to deliver some of the worst dialog in TV history when he rambles on about how she (remember, he's the wife) can't wait to feel their child growing inside him.
- Also used in an episode of Charmed when Piper and Leo have their powers magically switched while Piper is pregnant. Leo also somehow got all of Piper's symptoms. And again in the Sandman episode in which Leo ended up pregnant with Piper's baby until he felt the baby kick.
- In Mork and Mindy, Mork gets pregnant and lays an egg bigger than he is, due to Bizarre Alien Biology. It eventually hatches to reveal Mearth, played by 56-year old Jonathan Winters.
- (deadpan) "Look at that poor man, he's been screwed by a giant eyeball and now he's giving birth."
- The Pregnant Man was one of the recurring characters on the Australian sketch comedy programme Australia Youre Standing In It.
- In the Round the Twist episode "The Big Burp", Pete becomes pregnant by holding hands with and then kissing a dryad after peeing on her tree. This is apparently how dryads always reproduce. Making things even more stressful are the fact the pregnancy only takes about a day or two, and the "father" insists on hanging around him and badgering him about taking care of her daughter whilst remaining invisible and inaudible to everyone else. He then proceeds to experience an Express Delivery... by, as the title suggests, belching up the baby. Well, if that's how she made him pregnant in the first place...
- Used as a one-off joke in one of Scrubs' many fantasy sequences. Carla is asked what she would do if she won the lottery, and she imagines Turk being pregnant instead of her.
Turk: Stupid lotto.
- My Hero:
- One episode revolved around extraterrestrial George Sunday carrying an alien baby, and hilarity ensued when Dr. Piers Crispin saw the ultrasounds and thought it was Janet's father. (Just to make it a little crackier, the baby is revealed to be a gorilla. Yes.)
- Subverted in another episode, where he decided to give "sympathetic pregnancy" a go by inflating his stomach. Janet was pleased at first, but quickly got sick of it. "I've heard of sympathetic pregnancy, but not with stretch marks."
- In the infamous "Funny Aneurysm" Moment of a season in Married... with Children where Peggy and Marcy get pregnant at the same time, in one episode, Jefferson has a "sympathetic pregnancy".
Jefferson: My ovaries hurt!
Peggy: Wow, he is really good!
- Subverted in The Young Ones – Vyvyan’s pregnancy turns out to be the BIGGEST CASE of trapped wind on record.
- In the Farscape movie, "The Peacekeeper Wars", Rigel locates and ingests the remains of John and Aeryn so that their bodies can be reintegrated(don't ask). The process works, but Rigel discovers that he's carrying John and Aeryn's baby. The fetus is transplanted back into the mother so she can deliver the child normally. Or as normal as things get on Farscape...
- Grey's Anatomy has a episode with a pregnant man that Izzie, Christina, and Meredith steal from the psych ward. He has the bump and all the symptoms, even a positive pregnancy test. Turns out that he had a tumor-with teeth and hair, no less-growing inside him that produced the pregnancy hormone, thus the positive pregnancy test result. It was removed in surgery
- An episode of iCarly features a scene with Carly and Sam offering a picture of a pregnant man, along with a steaknife and BF Wangs gift certificate, for anyone who can find Sasha Striker.
- In the House episode "Skin Deep," a subplot involved a man dealing with couvade syndrome, to the point of experiencing labor pains along with his wife. House was amused, though the couple were not. Incidentally, it triggered a clue to the main story's problem. Also, see couvade in the Other category.
- In Eureka Sheriff Carter experiences couvade syndrome because of some technology that still needed some tweaking, not related to the main crisis of the week.
- Dans une galaxie prčs de chez vous had an episode where Brad became pregnant with an alien. After it was born, he became very over protective of his offspring, but it all ended with a Crowning Moment of Sadness when the alien baby vanished from existence at the end of its life, making Brad teary eyed of his lost "child".
- Continuing after an episode of when Carmen runs away, one scene of George Lopez shows Carmen (his daughter) returning home, but with a twist — she is pregnant! After this, George then realizes not only his daughter is pregnant, but also is his wife and his mother. Then, his son Max walks into the room with a large belly as well. After asking his father, "Where is this going to come out?", George abruptly wakes up and responds aloud, "If you are lucky, your bellybutton!" I suppose it was All Just a Dream induced from all the stress of worrying to where Carmen ran away.
- Rembrandt Brown from Sliders suffered this when the team went into a world where a global epidemic made women unable to carry to full term so men were fitted with vaguely marsupial artificial wombs to ensure the child is fully developed.
- Jake from The Troop gets bitten by a Snark and impregnated. Afterwards, he has to raise the baby snark briefly, making him miss out on the b-plot and providing a thinly veiled Aesop on the issues of teen pregnancy.
- Aside from the time(s) Colin got stuck with this— what with all of those female roles he ends up playing— there's at least one Irish Drinking Song from Whose Line Is It Anyway? that invokes this... which is promptly forgotten, next verse.
When I got home that night
My ovaries did swell
I puffed up like Jiffy Pop
I'm a dude— what the hell!?
- Choujuu Sentai Liveman Episode 31: "Mama! The Parasitic Monster's Cries": Junichi got impregnated by a Brainbeast, and out of it came a Cute Monster named Vega Baby, who sees Junichi as the mom. However, when the little monster sacrifices itself to save him, Junichi got a newfound respect for mothers (and the Brainbeast got very dead). It went from the wackiest Liveman episode ever to one of the saddest at lightning speed, although the last bit of the episode manages to insert one snarky humorous line. Also, looks like Junichi is going to have a hard time about making this event not get mentioned when fans talk about him.
- In one Sex-Ed PSA after two teenagers get magically transported to a gameshow style realm. After declaring that pregnancy is solely a girl's responsibility among other creeds, they temporarily made him pregnant to teach him some respect. It was certainly one of the more bizarre Sex-Ed videos out there.
- Max Sweeney in The L Word plays this trope for Drama. In a story ripped from the headlines, Max, a transgender man becomes pregnant after having sex with a cisgender man, Tom. Just because it's not fanfic, doesn't mean it works particularly well (although the article is clean, the site may be considered NSFW).
- Misfits combined this with Gender Bender and A Date with Rosie Palms. Unfortunately it only lasted one episode.
- In Mahou Sentai Magiranger/Power Rangers Mystic Force, Toad/Hekatoid seeds the clouds with his poisonous tadpoles.
- A promo image for The New Normal features a pregnant Bryan next to his boyfriend and their actual surrogate mother.
- In an episode of Sir Arthur Conan Doyles The Lost World, Malone becomes one to a water nymph, whose young gestates inside the father, and is then returned to the mother after a short time.
- Played for Laughs in 2point4 Children. Bill buys a pregnancy test but, when she goes to take it, realises one of the tester sticks is missing. It turns out that Ben has taken and used it and now believes he's pregnant.
- In Red vs. Blue, Tucker is impregnated (well, infected parasitically) by an alien as part of a prophecy. Tucker gives birth at the end of season four, although we do not see the birth take place (thankfully). This also means that we have absolutely no idea which orifice the baby emerged from (again, thankfully).
- The video for Will Young's single, Hopes and Fears. Pass the Brain Bleach.
- The Decemberists' The Tain LP, based on Táin Bó Cuailnge, presumably makes reference to the Curse of Macha (see Mythology below).
Chaplain: and now stricken with pangs
that tear at our backs like thistle down
the mirror's soft silver tain
reflects our last and birthing hour
- The theme song for Bill Nye the Science Guy is sometimes parodied like this:
"Bill Nye, his mom's a guy!"
- In the video for Chromeo's "When the Night Falls," the singer manages to impregnate a multitude of female fans via the Power of Rock. He later does this to himself, accidently, while looking in a mirror, before its revealed to be All Just a Dream.
- Jonathan Coulton takes this trope literally with his song "Seahorse", which describes the feelings of a male seahorse looking for a loyal bride.
- Done by Zeus with both Athena and Dionysus, if a fully grown and armored warrior woman bursting out of your skull after eating her mother AND stitching your pre-term half-mortal son into your thigh after you accidentally fry his mortal mom respectively counts.
- Also done by Loki (if transforming yourself into a mare in order to distract a horse so that the Ćsir will not have to pay its owner for his work and the giving birth to eight-legged steed Sleipnir counts). An alternate version of the legend claims that the woman involved was the giantess and witch on whom Loki fathered the Fenrir Wolf and the Midgard Serpent, and also that the result of Loki's pregnancy was Hel, Queen of the Dead.
- There's also a mostly lost myth that alludes to Loki turning into a human woman, marrying a farmer, and raising a family with him for a few years. It wasn't uncommon for Norse orphans to claim that Loki was their mother and their human fathers abandoned them in disgust at Loki's ruse.
- Another example is the Welsh text the Mabinogion, in which two brothers, Gwydion and Gilfaethwy, are successively turned into a stag and a hind, a boar and a sow, and a pair of wolves. They are in these forms long enough to bear an offspring from each transformation. After the brothers are turned back into redeemed humans, their animal offspring are then turned into humans and baptized.
- A variation occurs in Celtic myth. A wealthy landowner casually brags to Conor, King of Ulster about how his wife could outrun the King's best horses. Conor is less than pleased with this, and out of spite demands the woman compete in a race. If she fails, her husband will be killed on the spot. To make matters worse, the wife is heavily pregnant. She manages to win the race anyway, before collapsing on the ground and giving birth to a pair of twins. Enraged at how she was treated, she reveals that she is the goddess Macha. Before vanishing, she places a curse: whenever there is a threat to the city of Ulster, every adult male within will spontaneously go into labor for 9 days, leaving the city defenseless. Later on, Queen Maeve exploits this weakness when she goes after the Brown Bull of Cooley, leaving the hero Cuchulain to fight her armies singlehandedley.
- In Inuit religion, the first two humans were Aakulujjuusi and Uumarnituq, and were both males. Being the only two humans, they got lonely and decided to mate. Uumarnituq got pregnant, but obviously, he couldn't give birth. So a spell was put on to give him a vagina, and he became the first female.
- Older Than Dirt: In a Hittite legend, Kumarbi wants to overpower Anu, bites off his genitals, and becomes pregnant with his children. Kumarbi being male, they can't get out, so the gods have to cut Kumarbi open, or realize a magic ritual, Depending on the Writer. One text states the three new gods exited through Kumarbi's "good place."
- The Sumerian water god Enki once somehow impregnated himself.
- Rural folklore once claimed that yolkless chicken eggs (produced due hens' miss-timed reproductive process) were laid by roosters. Myths about basilisks and cockatrices sometimes claim these creatures hatch from such "cock's eggs".
- Parodied in Baby Blues. When watching a nature DVD which (correctly) explains male seahorse anatomy, Wanda simplifies it by telling Zoe that the male seahorse has the baby. Wanda then offhandedly asks if male seahorses do household chores as well.
- A Dilbert sequence involved Dogbert convincing Dilbert he had made him pregnant by giving him fertility drugs. Dilbert became visibly larger and greatly increased his eating to feed all the multiple babies he thought he had in their until Alice pointed out that a) it was impossible and b) the only evidence he had was his weight gain.
- In Safe Havens, mermen get pregnant.
- Played with in Zits. In one two-week arc, Jeremy, Hector and Pierce wear weighted vests that simulate the weight gain of pregnancy. The whole two weeks play out as if they actually are pregnant, with the first strip in the series featuring "pregnant" Jeremy, Hector and Pierce walking down the hallway, without any context as to why they're that way.
- In Exalted, Luna, the shapeshifting goddess of the moon and patron of the Lunar Exalted, has a form called the Two-Faced Bride, an aspect that apparently represents fertility and deceit and which usually appears as a pregnant human of any age and gender. Its apparent preferred form is a pregnant male youth, and it's mentioned that one city was actually visited by the Two-Faced Bride in the guise of a pregnant boy. The various bits of Shapeshifting Squick that are detailed for the Lunar Exalted implies that they, too, are capable of this.
- In Eberron, Changelings physically transform themselves due to doppelganger lineage. The transformation is so complete that females who take on male form can father children, and males who take on female form can become pregnant (but are apparently locked into female gender, if not necessarily the form they became pregnant in, until they give birth).
- Horribly, horribly deconstructed in Night Horrors: The Wicked Dead. A dhampyr can be produced regardless of gender, the only requirement being the parents must be a human-vampire couple, although either participant can get pregnant. Since this is a horror story, it does not end well.
- GURPS Technomancer (a world background where science and magic co-exist) has spells for transferring pregnancy, which includes the production of a magical "womb" for males. And the Bio-Tech supplement includes science and super-science for male pregnancy.
- Runequest Nandan, god of woman in a man body.
- Although rare, several erotic visual novels belonging to Otokonoko Genre has this as plot point. The technicalities are usually never discussed, and if it does, it's usually firmly in A Wizard Did It territory.
