Mpreg, short for male pregnancy, is a trope in fiction in which male characters become pregnant. Commonly found in fanfiction, particularly in slash fiction, mpreg explores themes of gender, identity, and societal norms. It has also appeared in mainstream media, where it is variously used for comedic, dramatic, or fantastical purposes.
Mpreg fiction frequently normalizes male pregnancy within its fictional worlds, allowing authors to focus on interpersonal relationships, domestic life, and emotional bonds rather than biological or societal conflicts. While the trope presents opportunities to challenge traditional gender roles, it has also been criticized for reinforcing traditional gender norms and overwriting female experiences. The trope intersects with broader discussions of gender and sexuality, though it is typically portrayed outside the context of transgender experiences.
Male pregnancy has been used in fiction for a long time, often with a comedic or monstrous presentation. [1] [2] For instance, the 1994 comedy film Junior followed a man who agreed to become pregnant as part of a scientific experiment. [3] [4] Additionally, the Alien franchise frames male pregnancy as a form of body horror, with the design of the Xenomorph species and its life cycle symbolizing rape and pregnancy. According to Alexandre O. Philippe, the depiction of male rape and pregnancy in Alien is a manifestation of widespread unspoken, unconscious patriarchal guilt that existed in the 1970s. [5]
The modern trope of mpreg originated in the 1980s, and became popular as an outgrowth of the Omegaverse in the Supernatural fandom in the 2000s and 2010s. [6] While not all mpreg fiction is fanfiction, even original fiction mpreg has its roots in the fandom trope. [3]
Mpreg fiction centers around the impregnation of a (typically cisgender [3] ) man by another man. [7] Mpreg tends to present male pregnancy as a positive and sometimes even unsurprising fact. [1] [6] The mechanism of the pregnancy varies depending on the work, from on-off magical interventions [1] to the biology of the Omegaverse. [6] The birthing process also varies, including c-section, special "birth canals", and birth through the anus or penis. [8] [3] Within the community, anal birth is typically looked down upon, often derisively referred to as "ass baby" stories. [9] Breastfeeding is commonly considered taboo in mpreg fiction and is rarely depicted. Many authors and readers view the inclusion of breastfeeding or pregnancy-enlarged breasts as compromising the masculinity of male characters, describing breastfeeding as a "squick" or a significant turn-off for much of the community, with one author expressly stating, "I have no desire to turn the male characters into females". [9] While some authors have chosen to include breastfeeding in their works, [3] these instances remain exceptional.
While not necessarily sexual, the stories are often partially pornographic. However, they can often simply focus on the romantic relationship between the central couple. [6] [8] [3] A survey of users of the primarily original fiction site "Mpreg Central" found that 57% preferred their stories to include sex, while 43% preferred it to be deemphasized or not included at all. [8] Mpreg fiction can also focus on the experience of pregnancy itself, including morning sickness, mood swings, and cravings, or its impact on a relationship. [10] Some mpreg does not focus on the pregnancy at all, choosing to write a romance in which a male pregnancy features but does not dominate the plot. Those authors may choose to focus on the domesticity of the couple or the romantic bond between them. [3] [1] [6]
Like most fanfiction, most mpreg fiction is written and consumed by women. [6] One original fiction author estimates that most of her audience is women in their 20s and above. [3] Other mpreg communities, like the forum Mpreg Central, are predominately gay men. They often want to be pregnant themselves or impregnate another man. [8] [11]
Reading and writing mpreg fiction is often stigmatized, including within the itself stigmatized world of slash fandom. [8] [12] [9] One author described other fans as opposing mpreg because it "turns the male characters into whiny, feminized versions of themselves". [12]
Mpreg also features as a niche genre of video pornography. [13] [14]
Within academia, Constance Penley was the first to write about mpreg in 1997, describing it as an subversive "extreme retooling of the male body". [15] [7] More recently, mpreg has both been criticized as reinforcing traditional gender roles and praised for subverting them. [10] [7] [1] Åström, in her analysis of mpreg fiction within the Supernatural fandom, describes some authors as pointedly asserting the character's masculinity, while others show the pregnant characters "expressing emotions stereotypically expected of women". Overall, she finds the stories "quite heteronormative", with "conventional stories set in a very unconventional universe". [1]
Some studies analyze the pregnant men in mpreg fiction as representations of women. [6] [1] [10]
A fandom is a subculture composed of fans characterized by a feeling of camaraderie with others who share a common interest. Fans typically are interested in even minor details of the objects of their fandom and spend a significant portion of their time and energy involved with their interest, often as a part of a social network with particular practices, differentiating fandom-affiliated people from those with only a casual interest.
Boys' love, also known by its abbreviation BL, is a genre of fictional media originating in Japan that depicts homoerotic relationships between male characters. It is typically created by women for a female audience, distinguishing it from the equivalent genre of homoerotic media created by and for gay men, though BL does also attract a male audience and can be produced by male creators. BL spans a wide range of media, including manga, anime, drama CDs, novels, video games, television series, films, and fan works.
Slash fiction is a genre of fan fiction that focuses on romantic or sexual relationships between fictional characters of the same sex. While the term "slash" originally referred only to stories in which male characters are involved in an explicit sexual relationship as a primary plot element, it is now also used to refer to any fan story containing a romantic pairing between same-sex characters. Many fans distinguish slash with female characters as a separate genre, commonly referred to as femslash.
Speculative and science fiction writers have often addressed the social, political, technological, and biological consequences of pregnancy and reproduction through the exploration of possible futures or alternative realities.
Blaise Zabini is a fictional character in J. K. Rowling's Harry Potter series. A minor character, his gender was not revealed until Harry Potter and the Half-Blood Prince, which resulted in several fans initially believing him to be female and errors in the series' Dutch translation. Despite this, he is more popular in fan-fiction of the series, partially due to his status as one of the few characters in Harry Potter of African descent.
Shipping is the desire by followers of a fandom for two or more people, either real-life people or fictional characters, to be in a romantic relationship. Shipping often takes the form of unofficial creative works, including fanfiction and fan art.
Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes (ova) and males producing smaller gametes (sperm). In nearly all animal species, offspring are carried by the female until birth, but in fish of the family Syngnathidae, males perform that function.
A Mary Sue is a type of fictional character, usually a young woman, who is portrayed as free of weaknesses or character flaws. The character type has acquired a pejorative reputation in fan communities, with the label "Mary Sue" often applied to any heroine who is considered to be unrealistically capable.
Fan fiction or fanfiction, also known as fan fic, fanfic, fic or FF, is fiction typically written in an amateur capacity by fans as a form of fan labor, unauthorized by, but based on, an existing work of fiction. The author uses copyrighted characters, settings, or other intellectual properties from the original creator(s) as a basis for their writing and can retain the original characters and settings, add their own, or both. Fan fiction ranges in length from a few sentences to novel-length and can be based on fictional and non-fictional media, including novels, movies, comics, television shows, musical groups, cartoons, anime and manga, and video games.

Born of Hope: The Ring of Barahir is a 2009 British fantasy adventure fan film directed by Kate Madison and written by Paula DiSante based on the appendices of J. R. R. Tolkien's 1954–55 novel The Lord of the Rings. The film centres on the communities affected by Sauron's war; the Dúnedain bloodline; and the story of Arathorn II and his relationship with Gilraen as they would be the parents of Aragorn, who became a key leader against Sauron.
Fan activism is the efforts of a fan community to raise awareness of social concerns or otherwise support the ideals expressed by objects of the fandom. The rise of fan activism has been attributed to the emergence of new media. A 2012 quantitative study by Kahne, Feezell, and Lee suggests that there may be a statistically significant relationship between youths' participation in interest-driven activities online and their civic engagement later on in life.

Beginning in the mid-2010s, significant discourse emerged within fan spaces such as Tumblr and Archive of Our Own (AO3) regarding the ethical implications of portraying taboo and abusive sexual content within shipping fanfiction. "Shipping"—the depiction of a romantic or sexual relationship between fictional characters—has long been a staple within fanfiction. The lack of censorship emerging from spaces such as AO3 allowed for the portrayal of disturbing or taboo dynamics within fan works, including incest, abuse, rape, and pedophilia.
