Simulated pregnancy, also known as factitious pregnancy, is a rare psychiatric condition classified as a factitious disorder imposed on self, in which an individual consciously and intentionally pretends to be pregnant despite knowing they are not, typically to gain attention, sympathy, or emotional care from others.[1][2] Unlike pseudocyesis (false pregnancy), which involves a genuine belief in pregnancy accompanied by physical symptoms such as amenorrhea, abdominal distension, and galactorrhea due to neuroendocrine changes, simulated pregnancy lacks these somatic manifestations and is driven by deliberate deception.[1][3]This condition is distinguished from related phenomena like delusion of pregnancy, a fixed false belief rooted in psychosis without intentional fabrication, and pseudopregnancy caused by organic factors such as hypothalamic tumors.[2][4] Simulated pregnancy can manifest in both women and men, often as part of broader factitious disorder patterns where the primary motivation is to assume the sick role, though external incentives like avoiding responsibilities or manipulating relationships may also play a role.[2] Case reports document instances in males, where psychoanalytic interpretations link the behavior to deep-seated identifications or unresolved conflicts, such as with maternal figures. The disorder is uncommon, with limited epidemiological data, but it poses diagnostic challenges as it may follow episodes of pseudocyesis or occur in individuals with histories of trauma, personality disorders, or prior factitious behaviors.[1]Diagnosis requires careful assessment to rule out genuine pregnancy, delusions, or malingering (feigning for external gain like financial benefit), often involving psychiatric evaluation and confrontation of the deception in a supportive manner.[2][4] Treatment typically focuses on psychotherapy to address underlying psychological needs, with multidisciplinary approaches including mental health professionals to build trust and prevent recurrence, though outcomes vary due to the deceptive nature of the condition.[1]
Overview and Definitions
Definition
A simulated pregnancy is an intentional effort by an individual to mimic the physical, behavioral, or social signs of pregnancy without an actual gestation occurring.[2] This deliberate act involves conscious deception or representation, where the person is fully aware of the absence of pregnancy and seeks to create an illusion through various means.[3] Unlike involuntary conditions such as pseudocyesis, simulated pregnancy emphasizes voluntariness and the absence of genuine physiological changes driven by psychological delusion.[5]The core elements of simulated pregnancy include the purposeful imitation of pregnancy indicators, such as altered body appearance, reported symptoms, or adherence to a fabricated timeline, all without underlying fetal development.[6] It is often classified as a factitious disorder imposed on self in psychiatric contexts, particularly when the simulation persists for external gains like attention or avoidance of consequences.[1] This intentionality distinguishes it from medical or hormonal mimics of pregnancy.
Distinction from Pseudocyesis
Simulated pregnancy differs fundamentally from pseudocyesis in terms of intentionality and psychological basis. In simulated pregnancy, individuals consciously and deliberately feign pregnancy, often using props such as prosthetic bellies or fabricated medical documentation, while fully aware that no actual pregnancy exists; this behavior is classified as a factitious disorder imposed on self, where the deception serves personal or external motivations without the presence of genuine delusion.[3][4] In contrast, pseudocyesis involves a sincere, non-delusional belief in pregnancy accompanied by psychosomatic symptoms like abdominal distension, cessation of menstruation, perceived fetal movements, nausea, breast engorgement, and even galactorrhea or labor-like pains, despite the absence of a fetus or placental tissue, as defined in the DSM-5.[3][7]This distinction highlights the absence of objective physical signs rooted in psychological distress in simulated cases, unlike pseudocyesis, where neuroendocrine and hormonal changes—such as elevated prolactin or cortisol levels—may mimic true pregnancy physiology.[3] Simulated pregnancy aligns more closely with broader factitious disorders, including Munchausen syndrome, where fabricated medical claims extend beyond pregnancy to induce sympathy, attention, or avoidance of responsibilities, often involving elaborate deceptions like altering ultrasound images or simulating complications.[1] However, it contrasts with involuntary phenomena like Couvade syndrome, in which male partners of pregnant women experience genuine sympathetic symptoms—such as weight gain, nausea, or back pain—without any intent to deceive, reflecting empathic identification rather than simulation.[8][9]Diagnostically, simulated pregnancy is identified through inconsistencies in reported history, negative pregnancy tests, or voluntary confession upon confrontation, lacking the need for extensive psychiatric intervention unless underlying personality disorders are present.[4] Pseudocyesis, however, typically requires multidisciplinary evaluation, including psychiatric assessment to rule out somatic delusions and medical imaging to confirm the absence of gestation, with treatment focusing on psychotherapy to address grief, desire for motherhood, or hormonal imbalances.[3][7] These criteria ensure that simulated cases are not misattributed to pseudocyesis, preventing inappropriate medical interventions.
Motivations and Contexts
Deceptive and Personal Motivations
Simulated pregnancy has been employed for deceptive purposes aimed at securing financial benefits, such as fraudulently obtaining maternity leave or related payments. In one notable case, a Georgia state employee named Robin Folsom was indicted in 2022 for wearing a prosthetic belly and fabricating medical documentation to claim paid family leave on three separate occasions, resulting in unauthorized paid family leave benefits.[10] Similarly, in Italy, Barbara Ioele was sentenced to prison in 2024 after confessing to simulating 17 pregnancies and miscarriages over several years, using stolen documents to collect approximately €110,000 in maternity allowances from the national social security system.[11] These instances illustrate how simulated pregnancy can exploit welfare systems designed to support genuine parental needs.Deception through simulated pregnancy also occurs to manipulate personal relationships, often to elicit commitment or emotional investment from partners. For example, in 2025, Libby Vernon from Staffordshire, UK, was jailed for 6 months after using fake ultrasound scans and a prosthetic bump to convince her partner of twin pregnancies, aiming to deepen their bond during a period of relational strain.[12] Another case involved Laura Owens, who in 2021 falsely claimed pregnancy with former Bachelor contestant Clayton Echard, fabricating medical records to pressure him into a relationship and support, leading to her indictment on fraud charges in 2025.[13] Such tactics can avoid social obligations, like ending a relationship, by leveraging the perceived gravity of impending parenthood to maintain ties.On a personal level, individuals may simulate pregnancy to fulfill psychological needs, including seeking attention or sympathy in private settings. Leslie Wilfred, diagnosed with Munchausen syndrome (a factitious disorder), faked a twin pregnancy and their stillbirth in 2008, presenting urns to her family to garner emotional support and concern during personal hardships.[14] In cases tied to role-playing, simulations occur in intimate contexts to explore identity or relational dynamics without broader disclosure, though documented examples remain limited due to their private nature. Factitious disorders, as classified in the DSM-5, underlie some instances where deception stems from an unmet need for care, distinct from delusional conditions like pseudocyesis.[3]Simulated pregnancy can also serve as a maladaptive coping mechanism for grief related to infertility, allowing temporary fulfillment of parental desires in non-public spheres. Historical precedents include the 1726hoax by Mary Toft in England, who simulated giving birth to rabbits to attract medical and public attention amid personal dissatisfaction, though her motives blended curiosity with a desire for notoriety in her community.[15] Case reports also document instances in males, such as a 2015 report of a man simulating pregnancy to gain sympathy from family during emotional distress, linked to underlying factitious disorder patterns.[2] These personal motivations highlight how simulation addresses internal voids but often escalates into broader relational harm.While such deceptions may provide short-term emotional relief, they frequently lead to legal consequences and erode trust in personal networks, raising ethical questions about consent and authenticity in intimate relationships.
Performative and Cultural Contexts
In performative contexts, simulated pregnancy serves as a tool for artistic expression and character portrayal in theater, film, and cosplay. Actors frequently employ silicone prosthetics or padded costumes to mimic pregnancy stages, allowing for realistic depictions without altering production timelines. For instance, in the 2012 film What to Expect When You're Expecting, Cameron Diaz wore adjustable fake baby bumps to portray a fitness instructor navigating pregnancy, progressing from small to larger sizes to reflect the character's timeline.[16] Similarly, in the 2024 comedy Babes, Ilana Glazer utilized a premade silicone prosthetic belly, airbrushed to match her skin tone and customized with details like a linea nigra for authenticity during exposed scenes.[17] In television, Gina Rodriguez donned multiple prosthetic bumps across Season 1 of Jane the Virgin (2014) to depict her character's unexpected pregnancy arc.[16]Mandy Moore also relied on four pairs of custom prosthetic breasts in This Is Us (2016–2022) to simulate Rebecca Pearson's triplet pregnancy, evolving from seed-filled prototypes to highly realistic silicone versions for accuracy across episodes.[18] In theater, productions like The Snapper (2018) at Dublin's Gate Theatre incorporated Moonbump silicone prosthetics for actors to embody pregnant roles convincingly on stage.[19]Cosplay communities extend this practice, using affordable foam or silicone bumps from vendors like Etsy to recreate pregnant characters from media, enhancing immersive role-playing at conventions.[20]Cultural contexts of simulated pregnancy often intertwine with rituals, traditions, and contemporary social expressions, highlighting societal values around fertility, motherhood, and identity. In 18th-century Europe, particularly amid the French Revolution's pronatalist fervor and English wartime patriotism, women adopted "The Pad"—a fashionable false belly worn under loose muslin gowns to simulate pregnancy as a statement of natural motherhood and national pride; satirical cartoons from 1793, such as Isaac Cruikshank's The Cestina Warehouse or Belly Piece Shop, depicted boutiques selling these props in varying sizes for different "gestational" stages.[21] Among the Kikuyu people of Kenya, traditional pregnancy rituals emphasize communal preparation for fertility and family continuity, including dietary practices and midwife involvement, without male presence during birth.[22] In modern settings, social media has popularized simulated pregnancy through prank announcements and photoshoots, often for humorous or aspirational purposes; for example, in China since the early 2020s, single women have embraced "pre-set maternity photoshoots" with fake bumps to capture idealized pregnancy imagery, reflecting cultural pressures around marriage and motherhood amid delayed family planning.[23] Such trends, including April Fools' pranks with prosthetic bumps, have sparked commercial growth but also criticism for trivializing infertility struggles.[24]Within transgender and non-binary communities, voluntary simulated pregnancy has emerged in the 2020s as a means of gender exploration and addressing maternal dysphoria through personal experimentation with prosthetics. Documented narratives describe individuals using fake bumps to embody pregnancy sensations, aiding empathy-building and identity affirmation in private or shared stories.[25]
Methods and Techniques
Physical Simulation Techniques
In simulated pregnancy as a factitious disorder, individuals may employ various deceptive tactics to mimic pregnancy, though specific physical methods are infrequently detailed in clinical literature due to the rarity of the condition. Reported approaches often involve behavioral adjustments and occasional use of simple props to fabricate visible signs, rather than sophisticated equipment.[26]Individuals might use everyday items like padding or rolled fabrics under clothing to simulate abdominal distension, progressing from subtle additions to more pronounced bulks to mimic trimester advancement. Such props can be secured with clothing or tape to maintain the illusion during interactions. Behavioral mimicry includes adopting pregnancy-like postures, such as increased lumbar lordosis or a waddling gait, to reinforce the deception without additional aids. In some cases, self-induced symptoms—such as using medications to halt menstruation or induce nausea—may be used to support claims, though these carry health risks and overlap with broader factitious behaviors.[3]Commercial prosthetics, like fake belly suits, could theoretically be adapted for prolonged deception, but there are no documented cases of their use in psychiatric simulated pregnancy; they are more commonly associated with costumes or training. Diagnosis often reveals such tactics through inconsistencies during medical examinations.
Digital and Technological Aids
Digital tools have facilitated new forms of deception in factitious disorders, including simulated pregnancy, particularly through online platforms where individuals can fabricate narratives without physical evidence. "Munchausen by Internet" involves posting false accounts of perinatal crises or pregnancy progress on social media to garner sympathy.[27]Photo editing software and AI generators enable the creation of misleading images, such as adding simulated baby bumps to photographs for social media announcements or hoaxes. As of 2025, platforms like Fotor's AI Pregnant Filter have been used to produce realistic maternity visuals from user photos, occasionally in deceptive contexts like false personal claims or viral rumors. Falsifying digital medical records, such as editing ultrasound images or prenatal reports, has also been reported in related factitious cases to simulate complications like fetal growth restriction.[28][29]Mobile apps designed for educational ultrasound simulation are not typically used for deception, but accessible technology lowers barriers to creating convincing digital fabrications. These methods highlight the evolving challenges in detecting factitious disorders in the digital age.
Historical and Psychological Aspects
Historical Examples
One of the earliest documented cases of simulated pregnancy occurred in 1726 in Godalming, Surrey, England, involving Mary Toft, a 25-year-old peasant woman who claimed to have given birth to rabbits after a miscarriage. Toft, assisted by her family, inserted dissected rabbit parts into her body to deceive local surgeons and even prominent physicians, including the court anatomist Nathaniel St. André, who initially believed her claims and presented the "births" to King George I's court. The hoax unraveled when Toft confessed under interrogation, leading to her brief imprisonment for fraud, though she was released due to public sympathy and lack of strong evidence against her accomplices.[30]In 1793, during the French Revolution, playwright and feminist Olympe de Gouges simulated pregnancy while imprisoned at the Conciergerie to postpone her execution by guillotine, as French law at the time delayed the execution of pregnant women until after delivery. At age 45, de Gouges, who had been sentenced to death for her political writings criticizing the revolutionary government, convinced initial examiners of her condition, but subsequent medical opinions deemed it improbable due to her age and lack of corroborating evidence. She was executed on November 3, 1793, without the delay.[31]A notable 19th-century instance unfolded in 1878 in England with Lady Annie Gooch, wife of baronet Sir Henry Cubitt Gooch, who was accused of fraudulently simulating pregnancy to secure an heir and preserve family inheritance. Lady Gooch, with alleged accomplices, attempted to pass off a substituted infant as her own biological child born in secret, using darkened rooms and false medical testimonies to deceive observers. The plot was exposed through investigations revealing inconsistencies in the birth narrative, leading to charges of conspiracy, though the case ended without conviction due to insufficient proof of her direct involvement.[32]The 21st century has seen simulated pregnancies proliferate through social media, often for attention or experimentation. In 2012, 17-year-old high school student Gaby Rodriguez in Washington state faked a pregnancy for five months as a sociology project to study societal reactions to teen pregnancy, using a prosthetic belly and staging an elaborate reveal with a doll. The hoax sparked national controversy when revealed, prompting discussions on bullying and stigma, but Rodriguez's intent was educational rather than deceptive for personal gain.[33]More recently, in 2025, 22-year-old Kira Cousins from Scotland admitted to faking an entire pregnancy on social media, complete with ultrasound images, a gender reveal party, and posts featuring a realistic silicone reborn doll as her "newborn." Cousins, who used a prosthetic bump throughout, deceived family and followers for months before confessing amid growing suspicions, citing personal motivations but facing backlash for emotional manipulation and online harassment that prompted police involvement. These digital-era cases reflect a shift toward performative simulations amplified by viral platforms, contrasting earlier frauds tied to personal or financial stakes.[34]
Psychological Underpinnings
Simulated pregnancy, as a deliberate deception, is classified as a factitious disorder imposed on self (FDIS) within the DSM-5's somatic symptom and related disorders category, where individuals fabricate pregnancy signs to gain medical attention or assume the sick role without external incentives.[3]The core psychological drivers of such simulations often stem from unresolved childhood trauma, including physical, emotional, or sexual abuse, which fosters a profound need for nurturing and emotional support that the individual seeks to elicit through feigned illness.[35] This behavior may represent a maladaptive coping mechanism rooted in attachment disruptions, where insecure or disorganized attachment styles—commonly linked to early neglect—manifest as a compulsion to secure care and validation via deception.[35] In clinical contexts, these simulations can function as a form of dissociative role-playing, allowing temporary escape into an idealized identity of vulnerability and dependency, particularly among those with comorbid personality disturbances that impair self-concept stability.[26]Such motivations highlight broader identity exploration challenges, where the simulated pregnancy serves as a symbolic enactment of unmet relational needs or trauma responses, enabling the individual to externalize internal conflicts through the assumed role of expectant parent.[35] Historical cases, such as those involving serial deceptions during pregnancy, illustrate how these underpinnings can escalate, intertwining personal trauma with repeated behavioral patterns.[36] Therapeutic interventions targeting these roots, including trauma-focused psychotherapy, aim to address the underlying attachment wounds and reduce reliance on factitious behaviors.[35]
Implications and Considerations
Ethical and Legal Issues
Simulated pregnancies, particularly when employed for deceptive purposes, raise profound ethical concerns regarding the erosion of trust in personal relationships and broader societal norms. Deception in intimate contexts, such as falsely claiming a pregnancy to manipulate a partner, can inflict severe emotional distress, including fabricated grief over miscarriages or infant deaths, leading to long-term psychological harm for victims and their families.[37][12] In performative scenarios like pranks or social media hoaxes, the lack of prior consent exacerbates these issues, as recipients may experience heightened anxiety, especially those with histories of infertility or pregnancy loss, underscoring debates about the moral boundaries of humor involving sensitive life events.[38]Legally, simulated pregnancies pursued for financial gain often constitute fraud, with consequences varying by jurisdiction. In the United States, individuals have faced felony charges under welfare fraud statutes for falsely claiming pregnancies to obtain benefits; for instance, a San Jose woman was sentenced to over three years in prison in 2007 after using stolen identities to secure $4,501 in cash aid and food stamps by simulating a pregnancy and birth.[39] Similarly, a Georgia state employee was indicted in 2022 on charges of false statements and identity fraud for faking multiple pregnancies to claim approximately seven weeks of paid leave, highlighting how such acts violate false pretenses laws and the False Claims Act, which imposes treble damages and civil penalties ranging from $14,024 to $28,056 per false claim (as adjusted for inflation in 2024; subject to annual updates).[40][41]In the United Kingdom, deceptive simulations to access maternity benefits fall under the Fraud Act 2006, prohibiting false representations for gain. As of April 2025, statutory maternity pay (SMP) is paid for up to 39 weeks: 90% of average weekly earnings for the first 6 weeks, and the lower of £187.18 per week or 90% of average weekly earnings for the next 33 weeks; misuse through faked pregnancies can lead to criminal prosecution, though specific cases more commonly involve relational deception charged as false communications causing harm, resulting in imprisonment and restraining orders.[42][43][37]Within professional contexts, ethical guidelines emphasize transparency to avoid misleading participants. For actors simulating pregnancy in theater or film—often using prosthetic aids—industry standards from unions like Actors' Equity Association require clear contextual framing as fiction, ensuring audiences understand the performative nature without real-world deception.[44] In therapeutic or medical training settings, simulated pregnancies via role-playing or standardized patients must adhere to informed consent protocols, as outlined in simulation-based education frameworks, to prevent any unintended psychological impact on trainees or patients while fostering ethical practice.[45]
Health and Social Impacts
Simulated pregnancies, often involving the use of weighted props or garments to mimic physical changes, can impose significant physical strain on the individual. Studies utilizing pregnancy simulators, such as weighted vests approximating third-trimester weight gain (around 8-10 kg), have demonstrated reduced balance and mobility; for instance, participants experienced shorter single-leg stance times (from 58.5 seconds to 53.8 seconds with eyes open) and decreased functional reach distances (from 32.5 cm to 27.3 cm), alongside slower gait speeds and shorter step lengths. These alterations increase the risk of falls and musculoskeletal discomfort, including potential back pain from prolonged weight distribution shifts, though direct pain metrics vary by duration of use. Additionally, constrictive elements like belly bands, if worn excessively, may impair blood flow to the abdomen, exacerbating fatigue or circulatory issues.[46][47][48]The psychological burden of sustaining a simulated pregnancy through deception often manifests as heightened anxiety and stress from the ongoing need to fabricate symptoms and evade scrutiny. Individuals engaging in such deceptions may align with factitious disorder patterns, where feigning illness leads to emotional exhaustion, guilt, or escalated mental health challenges like depression upon revelation. This toll is compounded by the cognitive load of maintaining consistency, potentially triggering paranoia or relational isolation as the deception persists.[26][49]Socially, discovery of a simulated pregnancy frequently erodes trust within personal relationships, leading to fractured partnerships, familial estrangement, or diminished social support networks. For example, partners or family members may experience profound betrayal, resulting in long-term relational strain and emotional distress for all involved. On a broader scale, the proliferation of pregnancy hoaxes in the 2020s, particularly via social media pranks like April Fools' announcements, has fostered societal skepticism toward genuine pregnancy reveals, diminishing communal joy and amplifying doubt in public sharing of reproductive milestones.[50][51][52]In controlled therapeutic contexts, however, simulated pregnancies offer positive outcomes, such as enhanced empathy among partners in infertility support settings. Programs employing empathy simulators have been shown to improve understanding of pregnancy's physical demands, with participants reporting greater compassion and positive attitudes toward expectant individuals (e.g., Jefferson Scale of Physician Empathy scores rising from 103.71 to 107.04). These interventions, adapted for couples navigating infertility, can strengthen relational bonds by fostering mutual insight and reducing isolation during treatment.[47][53]
