What Is a Neovagina? Surgical Techniques and Care

A neovagina is a surgically or non-surgically created vaginal canal in someone who was born without one or whose anatomy does not include one. The two largest groups who undergo neovaginal creation are women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a congenital condition in which the vagina and uterus fail to develop, and transgender women seeking gender-affirming surgery. The techniques range from gradual self-dilation with no surgery at all to complex operations using penile skin, intestinal segments, or peritoneal tissue, and outcomes across most approaches are broadly positive, though each comes with distinct trade-offs in recovery, maintenance, and long-term biology.

Who Needs a Neovagina and Why

The most common medical reason for neovaginal creation is MRKH syndrome, which affects roughly 1 in 4,000 to 5,000 women. These individuals typically have functioning ovaries and external genitalia but are born with an absent or severely shortened vagina and, in most cases, an absent uterus. Outside MRKH, some women with complete androgen insensitivity syndrome (CAIS) also have a shortened vaginal canal. In all of these cases, the goal of creating a neovagina is to allow penetrative sexual activity and, in a broader sense, to improve quality of life and body image. Transgender women who undergo gender-affirming vaginoplasty represent a second major group; penile and scrotal tissue is repurposed to construct both the external vulva and the internal canal.¹ Although the clinical populations differ, the underlying surgical and biological challenges overlap considerably, and techniques developed for one group have often been adapted for the other.

Non-Surgical Dilation

For women with MRKH or CAIS, doctors often recommend non-surgical dilation as the first step. The principle is simple: progressively larger dilators are pressed against the vaginal dimple for set periods each day, gradually stretching the tissue to form a functional canal. A well-studied version of this approach, called Ingram’s method, uses a bicycle-seat-like stool so the patient’s own body weight provides the pressure, reducing the effort needed during each session.² A systematic review covering over 1,500 women with MRKH found that vaginal dilation is a viable first-line treatment, with multiple studies reporting functional success.³

In one program treating women with both MRKH and CAIS, about 81% of participants who completed dilation became sexually active without reported difficulties, and vaginal length increased from an average of 4.0 cm to 8.5 cm.⁴ The advantages of dilation are that it avoids surgical risk, does not leave scars, and produces a lining that more closely resembles natural vaginal tissue. The disadvantages are that it requires significant time commitment and motivation, and it does not work for everyone. When dilation fails or when the patient prefers surgical creation, a range of operative techniques are available.

Penile Inversion Vaginoplasty

For transgender women, penile inversion vaginoplasty (PIV) is the most widely performed approach. The surgeon uses the skin of the penis, sometimes supplemented with scrotal skin, to line the walls of a newly created vaginal canal. The glans penis is reshaped into a neoclitoris, and the urethra is shortened and repositioned.⁵ Contemporary techniques also address the construction of the vulvar labia and careful placement of the urethral opening to reduce the risk of spraying during urination.⁶

One of the main limitations of PIV is that the available penile skin determines how deep the canal can be. Patients who underwent hormonal suppression before puberty or who simply have less genital tissue may not have enough skin to achieve the desired depth. In those cases, surgeons sometimes use skin grafts from other body sites to supplement the lining. This is one reason newer alternatives, including peritoneal flap techniques, have gained traction.

Bowel and Peritoneal Flap Techniques

Intestinal vaginoplasty uses a segment of the patient’s bowel to line the neovaginal canal. The sigmoid colon is the preferred segment because its diameter closely matches a vagina’s, its walls are thick enough to resist trauma, and it produces mucus that acts as natural lubrication without being excessively wet. Ileal (small-bowel) segments were tried earlier but fell out of favor because they produced too much mucus and had a shorter tissue stalk, making surgical placement more difficult.⁷ A systematic review of bowel vaginoplasty across multiple patient populations confirmed that it provides a self-lubricating canal with low failure rates and typically does not require ongoing dilation.⁸ That said, sigmoid vaginoplasty is a more invasive abdominal surgery, carries risks related to bowel anastomosis, and can sometimes produce a persistent, mildly unpleasant mucus discharge that bothers some patients.

Peritoneal flap vaginoplasty is a newer alternative that uses the peritoneum, the thin membrane lining the abdominal cavity, to create the canal. In the gender-affirming context, robotic-assisted peritoneal flap techniques have been developed as a way to achieve good vaginal depth even when penile skin is limited. Early experience comparing the da Vinci Single Port and Xi robotic systems has shown this approach to be a safe alternative to traditional PIV.⁹ In MRKH patients, a related approach called the Davydov procedure pulls peritoneum down laparoscopically to line the canal. A series of four MRKH patients treated with a modified version achieved functional canals averaging 8 cm in length, and all who attempted intercourse were successful.¹⁰

How the Body Adapts to a Neovagina

One of the more fascinating aspects of neovaginal biology is what happens to the transplanted tissue over time. When skin grafts are used, as in the McIndoe procedure for MRKH patients, the grafted skin gradually changes. Biopsies have shown that skin grafts partially adapt to resemble vaginal mucosa by about six months and fully adapt by about twelve months after surgery.¹¹ However, this adaptation does not appear to happen with penile and scrotal skin flaps used in transgender vaginoplasty, where the tissue retains its original histological characteristics long term.¹²

Peritoneal flap neovaginas tell a different story. Biopsies from patients who received robotic-assisted peritoneal flap vaginoplasty have shown that the peritoneal lining undergoes metaplasia, transforming from the flat mesothelial cells that normally line the abdomen into stratified squamous epithelium, the same cell type found in a natal vagina. In one investigation, all five biopsied patients showed this transformation, with no residual mesothelial cells remaining.¹³ This finding is medically encouraging, but the same study noted that a majority of the biopsies also showed features resembling low-grade dysplasia, a detail whose clinical significance remains unclear and likely warrants long-term monitoring.

The microbial community inside a neovagina also differs from that of a natal vagina. In natal vaginas, Lactobacillus species typically dominate. In penile-inversion neovaginas, the bacterial mix more closely resembles the profile seen in natal vaginas with bacterial vaginosis, with higher diversity and different dominant species such as Porphyromonas, Prevotella, and Mobiluncus.¹⁴ Intestinal neovaginas, unsurprisingly, harbor a microbiome more like the colorectum.¹⁵ Whether these microbial differences have meaningful health consequences, such as increased susceptibility to infections, is still being studied, but they do mean that standard vaginal probiotics designed to promote Lactobacillus are unlikely to behave the same way in a neovagina.

Complications and Their Management

No surgical creation of a neovagina is without risk, though serious complications are relatively uncommon. A large meta-analysis covering over 3,700 vaginoplasty cases in transgender women found stenosis (narrowing of the canal) in about 14% of cases, fistula formation in about 2%, tissue necrosis in about 1%, and prolapse of the neovagina in about 4%.¹⁶ Stenosis is the most common long-term issue across all neovaginal techniques and is the primary reason patients are instructed to dilate regularly after surgery. One review cited the stenosis rate at around 19%.¹⁷

Rectovaginal fistula, an abnormal connection between the neovagina and the rectum, is rarer but more serious. A systematic review of fistula repair after transgender vaginoplasty identified multiple repair strategies, from conservative management to reconstructive flap surgery. Recurrence after repair was reported in about 15% of cases, suggesting that while repair is possible, it sometimes requires more than one attempt.¹⁸ Prolapse, where the neovaginal canal telescopes outward, can be mitigated during the initial surgery by anchoring the canal to the sacrospinous ligament, a technique that has been shown to significantly reduce the risk.¹⁹

Sexual Function and Patient Satisfaction

For many patients, the ability to have satisfying sexual activity is the central goal of neovaginal creation. The evidence here is largely encouraging. In transgender women, the neoclitoris fashioned from the glans penis retains long-term erogenous sensation, and the vast majority of patients report being able to achieve orgasm.²⁰ The same large meta-analysis mentioned earlier found that about 70% of patients reported orgasm capability, satisfaction with overall results was about 93%, and the regret rate was around 1%.²¹

Among women with MRKH treated surgically, about 79% reported that the procedure improved their quality of life, and 55% reported improved self-image.²² A study measuring well-being in women with vaginal agenesis found that their quality-of-life scores were comparable to the general population’s, though vaginismus (involuntary tightening of the pelvic floor muscles during penetration) remained an issue for some.²³

When comparing sigmoid vaginoplasty to penile inversion in transgender women, a recent study found no significant difference in satisfaction scores, genital self-image, or sexual well-being between the two approaches. Both groups rated their satisfaction with the surgical result at about 7 out of 10.²⁴ This is useful for patients deciding between techniques: the sigmoid approach offers self-lubrication and less dependence on dilation, while PIV is less invasive and avoids abdominal surgery, yet long-term satisfaction appears comparable.

Hair Removal Before Surgery

A practical concern unique to transgender vaginoplasty is that penile and scrotal skin often bears hair follicles. If those follicles are not addressed before surgery, hair can grow inside the neovagina, causing irritation, odor, and in some cases contributing to infections or stone-like concretions called bezoars. Preoperative hair removal is therefore considered a standard step. A comparison of laser hair removal and electrolysis in patients preparing for vaginoplasty found that laser treatment was faster, required fewer sessions, caused less pain, and cost less overall. For patients with dark genital hair, laser is now recommended as first-line treatment.²⁵ Combining preoperative hair removal with intraoperative cauterization of remaining follicles has been shown to reduce infections and calculus formation afterward.²⁶

HPV and Cancer Screening

Whether a neovagina needs cancer screening the way a cervix does is a question that has only recently begun to receive serious attention. Penile and scrotal skin can harbor human papillomavirus (HPV) before it is ever used in surgery, and sexual activity after surgery introduces further exposure. A study of transgender women in Thailand found that about two-thirds had some HPV type in their neovagina, and about 41% had high-risk strains associated with cancer. Inconsistent condom use and prior syphilis exposure were both associated with higher infection rates.²⁷

There have also been reported cases of HPV-related squamous cell carcinoma arising in a neovagina. These are rare, but the fact that they occur at all has prompted calls for formalized screening guidelines. Some researchers have suggested that HPV testing rather than cytology (the equivalent of a Pap smear) might be more appropriate for neovaginal tissue, since it is unclear how well standard cytologic interpretation applies to what is, after all, transplanted skin rather than cervical tissue. Preoperative screening of the genital skin that will be used in surgery has also been proposed as a way to identify patients who may need closer follow-up.²⁸ No universal screening protocol exists yet, but HPV vaccination remains relevant for anyone with a neovagina who is sexually active.

Tissue Engineering and the Frontier of Lab-Grown Organs

Perhaps the most ambitious work in this field involves growing vaginal tissue from the patient’s own cells and implanting it. A pilot study published in The Lancet reported on tissue-engineered vaginal organs implanted in patients with a congenital abnormality. The engineered organs showed normal structure and function, with follow-up extending up to eight years.²⁹ This approach uses a biodegradable scaffold seeded with the patient’s own muscle and epithelial cells, which is then shaped and surgically implanted. Because the tissue is autologous, the risk of rejection is theoretically eliminated. The technique remains experimental and has not entered routine clinical practice, but it represents a potential path toward neovaginas that more closely replicate native tissue from the start.

Fertility and the Possibility of Pregnancy

For women with MRKH syndrome, who typically lack a uterus, the creation of a neovagina does not itself enable pregnancy. However, the existence of a functional neovagina becomes relevant if a uterus transplant is ever pursued. Research into uterine transplantation has explored which methods of neovagina creation leave the best anatomical conditions for a subsequent transplant. Key criteria include sufficient vaginal length, a natural vaginal axis, absence of major prior abdominal surgery, and a mucosal lining rather than skin. Based on these criteria, the Vecchietti technique (a form of traction-based dilation assisted laparoscopically) has been identified as providing ideal conditions, with non-surgical self-dilation also considered potentially suitable.³⁰

The concept of uterine transplantation in transgender women has also been discussed, though it remains entirely theoretical at this point. The anatomical and immunological challenges are considerable, but researchers have noted that small numbers of live births have occurred in cisgender women with skin neovaginas who received uterine transplants, proving that pregnancy is at least biologically possible in the presence of a non-native vaginal canal.³¹

Timing of Surgery in Younger Patients

Both MRKH patients and transgender adolescents raise the question of when neovaginal creation should happen. For girls born with differences of sex development such as congenital adrenal hyperplasia (CAH), a trend in recent decades has moved away from early childhood genital surgery and toward waiting until adolescence or young adulthood. Research has confirmed that vaginoplasty after menarche in CAH patients is technically feasible, and families are now increasingly advised to keep an open mind about delaying surgical corrections.³² The rationale is that the patient can then participate in informed consent, the tissues are more mature, and the psychological context is better understood.

For transgender adolescents, professional guidelines have historically set a minimum age of 18 for irreversible genital surgery. Reports have documented cases where vaginoplasty was performed on minors in the United States, raising ethical debates about consent, the permanence of the procedure, and the adequacy of psychological evaluation in younger patients.³³ The tension here is genuine: on one hand, earlier puberty suppression with hormone analogs can limit the amount of genital tissue available for PIV, creating a surgical argument for acting before full growth is curtailed. On the other hand, the irreversibility of the surgery, combined with the evolving nature of gender identity in adolescence, argues for caution. Clinical practice varies by country and institution, and this remains one of the more actively debated areas in the field.
