Genital reconstruction surgery encompasses a wide range of procedures that reshape or create genital structures, whether for gender affirmation, repair of congenital differences, or restoration after injury or cancer. The field has evolved rapidly, with techniques refined over more than a century and outcomes steadily improving. Satisfaction rates across modern gender-affirming genital surgeries run above 90%, and pooled regret rates sit around 1%, though the procedures remain among the most technically demanding in surgery and carry meaningful complication risks that anyone considering them should understand in detail.
What the Term Actually Covers
Genital reconstruction is not a single operation. It is an umbrella that shelters dozens of distinct surgical approaches, chosen based on the patient’s anatomy, goals, and medical history. The largest and fastest-growing category is gender-affirming genital surgery, which includes feminizing procedures like vaginoplasty and vulvoplasty, and masculinizing procedures like phalloplasty and metoidioplasty. But the same reconstructive principles also apply to children born with differences of sex development such as congenital adrenal hyperplasia, adults who have lost genital tissue to cancer or trauma, and people with congenital absence of the vagina. Surgical techniques developed in one context frequently cross-pollinate into another, and the surgeons who perform this work often train across multiple subspecialties.
Feminizing Genital Surgery
The most established feminizing procedure is penile inversion vaginoplasty, in which penile and scrotal skin is used to line a surgically created vaginal canal between the bladder and rectum. A neoclitoris is fashioned from the glans penis, preserving its nerve supply, and the external appearance of the vulva is sculpted from remaining tissue. This technique has been refined since the mid-twentieth century and remains the most widely performed worldwide. One limitation is lubrication: penile and scrotal skin have no inherent ability to self-lubricate, though when urethral tissue is incorporated and lubricating accessory glands are retained, some sexually responsive secretory fluid can result.1Sexual Medicine Reviews.

Peritoneal flap vaginoplasty has gained traction as an alternative, particularly with the adoption of robotic-assisted surgery. In this approach, a graft harvested from the peritoneum, the membrane lining the abdominal cavity, is used to line the vaginal canal. A comparative study found that peritoneal flap vaginoplasty yielded greater vaginal depth at both one and six months compared to penile inversion, with no rectal injuries in the peritoneal group versus three in the penile inversion group, and less blood loss overall.2Andrology. Robot‐Assisted Peritoneal Flap Vaginoplasty Versus Penile Inversion Vaginoplasty for Gender Affirming Surgery Operating time, hospital stay, and rates of vaginal stenosis were similar between the two.
One intriguing biological finding involves what happens to peritoneal tissue after it is placed in the vaginal canal. Biopsies of peritoneal neovaginas have shown that the tissue undergoes metaplasia, transforming from the thin mesothelial lining of the peritoneum into stratified squamous epithelium, the same type of tissue that lines a natal vagina. No residual mesothelial cells remained in any of the sampled biopsies, though some showed features that could mimic low-grade dysplasia on pathology slides, requiring careful interpretation to avoid unnecessary alarm.3PubMed.

Both peritoneal and colonic tissue have secretory capacity, which is sometimes marketed as “self-lubrication.” The reality is more nuanced: fluid production from these tissues is continuous rather than responsive to sexual arousal, and the volume may be excessive or inadequate for a given patient’s expectations.4PubMed. Vaginal self-lubrication following peritoneal, penile inversion, and colonic gender-affirming vaginoplasty: a physiologic, anatomic, and histologic review No current technique perfectly replicates the arousal-linked lubrication of a natal vagina, and most patients will use supplemental lubricant regardless of surgical method.
Masculinizing Genital Surgery
Two principal options exist for creating a penis: phalloplasty and metoidioplasty. They differ fundamentally in ambition and trade-offs, and choosing between them is one of the most consequential decisions in transmasculine surgical care.
Phalloplasty constructs a full-sized neophallus using a flap of tissue transferred from another part of the body. The two most common donor sites are the forearm (radial forearm flap) and the outer thigh (anterolateral thigh flap). A large analysis comparing these two approaches across over 400 cases found no significant differences in rates of fistulas requiring surgery, stricture rates, flap revision rates, or prosthesis-related complications.5PubMed Central. Comparison of Radial Forearm Flap and Antero-Lateral Thigh Flap Phalloplasty: Analysis of 413 Cases The forearm flap tends to produce better sensation, however, because the forearm skin is thinner and more richly innervated. In a smaller series, sensitivity in the radial forearm flap was judged superior to the anterolateral thigh flap, and the forearm flap remains the preferred choice at many centers unless a free flap is medically inadvisable or the patient prefers a less visible donor site.6Advances in Urology. Reconstructive Surgery for Severe Penile Inadequacy: Phalloplasty with a Free Radial Forearm Flap or a Pedicled Anterolateral Thigh Flap
Metoidioplasty takes a different approach entirely. Rather than building a phallus from distant tissue, it works with what testosterone therapy has already done. Testosterone enlarges the clitoris over time, and metoidioplasty releases the clitoral shaft from its surrounding ligaments and suspensory structures to maximize its projecting length. The resulting neophallus is smaller than what phalloplasty produces, but it retains full erogenous sensation and typically does not require a prosthesis to achieve erection. The Belgrade technique, one of the most refined versions of the procedure, adds urethral lengthening using buccal mucosa grafts and labia minora flaps, and some protocols incorporate preoperative topical dihydrotestosterone gel and a vacuum device to further enhance clitoral size before surgery.7Sexual Medicine. Is Clitoral Release Another Term for Metoidioplasty? A Systematic Review and Meta-Analysis of Metoidioplasty Surgical Technique and Outcomes
One common assumption is that longer testosterone use before metoidioplasty will produce a longer result. A study measuring neophallus length after metoidioplasty found that time on testosterone did not significantly correlate with either stretched clitoral length or final exposed neophallus length.8PubMed Central. Assessment of neophallus length following metoidioplasty There appears to be a ceiling effect: once the clitoris has responded to testosterone over the first year or two, additional years of therapy do not reliably add more growth.
The Urethral Lengthening Problem
If there is one area where genital reconstruction surgery still struggles, it is building a functional urethra. In masculinizing procedures, creating a urethra that allows standing urination requires extending the native urethra through newly constructed tissue, a process called urethral lengthening. This step is the single largest driver of complications. A systematic review found that urethral complications, primarily strictures and fistulas, require additional surgeries in roughly 30 to 50% of patients.9international journal of impotence research. Systematic review of the outcomes of urethroplasty following urethral lengthening in transgender men
One study reported stricture formation in about 63% of phalloplasty cases and fistula formation in about 27%.10PubMed. Functional Outcomes and Urological Complications after Genital Gender Affirming Surgery with Urethral Lengthening in Transgender Men These numbers sound alarming, and they are high, but context matters: many strictures and fistulas are correctable with secondary procedures, and the field is actively working to reduce these rates. Staged urethroplasty approaches, where the repair is done in two separate operations rather than all at once, have shown the lowest recurrence rates, ranging from 0 to 25%, while single-stage repairs without tissue augmentation carry recurrence rates around 50%.11international journal of impotence research. Systematic review of the outcomes of urethroplasty following urethral lengthening in transgender men
Procedures that skip urethral lengthening altogether have markedly lower complication rates without clear differences in patient-reported satisfaction, a finding that has led some surgeons to suggest that standing urination should be framed as an optional add-on rather than a default component of masculinizing surgery.12PubMed.

Sensation and Sexual Function
A question that weighs heavily on anyone considering genital reconstruction is whether the result will have sensation and, more specifically, whether orgasm will still be possible. The evidence here is broadly encouraging. Following vaginoplasty, most patients report that the neoclitoris provides erogenous sensation, and the neovaginal canal develops vibratory and pressure sensation. A study found that 80% of participants who could orgasm before surgery reported orgasm afterward, and 29% of those who had not experienced orgasm preoperatively achieved it for the first time after surgery.13BJU International. Sexual satisfaction, sexual function, and orgasm after gender‐affirming vaginoplasty and vulvoplasty A systematic review across more than 2,300 patients found orgasm rates ranging widely by study, with a median of about 80%.14PubMed. Sexual health after vaginoplasty: A systematic review
After phalloplasty, sensory outcomes are more variable. The largest series in the literature report sensation in the neophallus that is slightly less than what is measured in control men, but erogenous sensation, including orgasm, is present in nearly all patients after several months of nerve recovery.15PubMed. Sensibility, Sensation, and Nerve Regeneration after Reconstructive Genital Surgery: Evolving Concepts in Neurobiology The European Society for Sexual Medicine’s position statement reported that every transmasculine individual in the reviewed data and 85% of transfeminine individuals could reach orgasm, either through masturbation or intercourse. Phalloplasty itself was not found to be a critical factor in reaching orgasm, but limited sensitivity and absence of erectile function without a prosthesis did reduce sexual satisfaction in some patients.16Sexual Medicine.

Complications and Recovery After Vaginoplasty
Aside from the urethral issues discussed above for masculinizing procedures, feminizing surgeries carry their own set of postoperative challenges. Neovaginal stenosis, the gradual narrowing or shortening of the vaginal canal, is one of the most common and requires a long-term commitment to dilation, typically with graduated dilators used daily for the first several months and then less frequently over time. Urinary incontinence, prolonged pelvic pain, and wound healing complications also occur.17Transgender Health. Indications for the Utilization of Pelvic Floor Physical Therapy for Transgender Women Following Gender-Affirming Vaginoplasty: A Narrative Review
Pelvic floor physical therapy has been promoted as a way to improve dilation ease, reduce pain, and manage urinary symptoms after vaginoplasty. Small retrospective studies showed promising results. However, a randomized trial comparing perioperative pelvic floor physical therapy to standard postoperative care found no differences in vaginal length, ease of dilation, pain with dilation, or pelvic floor symptoms at 12 weeks.18PubMed. A randomized trial comparing perioperative pelvic FLOor physical therapy to current standard of care in transgender Women undergoing vaginoplasty for gendER affirmation: the FLOWER Trial This does not mean pelvic floor therapy is useless for every patient, but it does suggest that routine referral may not improve outcomes above what a good standard dilation protocol already achieves.
Rare but serious complications include recto-neovaginal fistula, an abnormal connection between the rectum and the vaginal canal. Repairing such fistulas is more complicated than in cisgender anatomy because the perineal structures have been surgically altered. Techniques using the gracilis muscle from the inner thigh have been described to successfully close these defects.19PubMed Central.

Satisfaction, Regret, and Psychological Outcomes
Across the surgical literature, postoperative satisfaction rates for gender-affirming genital surgery consistently fall between 94 and 100%, depending on the specific procedure. A follow-up study reported that 6% of participants expressed dissatisfaction or regret, and those cases were associated with preoperative psychological symptoms or surgical complications. Patients who were satisfied scored similarly to the general population on quality-of-life measures, while those with regret scored markedly lower.20PubMed. Surgical Satisfaction, Quality of Life, and Their Association After Gender-Affirming Surgery: A Follow-up Study
A meta-analysis pooling nearly 8,000 patients across 27 studies found a regret prevalence of about 1%.21PubMed Central. Regret after Gender-affirmation Surgery: A Systematic Review and Meta-analysis of Prevalence When surgeons were surveyed directly, 57% had encountered at least one patient who expressed regret, but the total number across all surveyed surgeons was 62 patients, representing 0.2 to 0.3% of their combined caseloads. The reasons for regret were varied: about 42% involved a true change in gender identity or misdiagnosis, 37% stemmed from social factors like family rejection or alienation, and 8% were related to medical dissatisfaction with the surgical result itself.22PubMed Central. Guiding the conversation—types of regret after gender-affirming surgery and their associated etiologies The fact that social regret accounts for over a third of cases underscores that surgical outcomes do not exist in a vacuum; the environment a person returns to after surgery profoundly shapes their experience.
Reconstruction for Congenital Conditions
Gender-affirming surgery gets most of the public attention, but genital reconstruction also has deep roots in pediatric urology and the management of congenital conditions. Congenital adrenal hyperplasia, a condition where excess prenatal androgen exposure leads to virilization of the external genitalia in girls, has historically been one of the primary indications. Surgery can include clitoroplasty, vaginoplasty, or combined procedures, and the approach must be individualized based on the degree of virilization and the anatomic relationship between the vagina and urogenital sinus.23PubMed Central. Feminizing genital reconstruction in congenital adrenal hyperplasia
The timing of surgery in children with congenital adrenal hyperplasia has become increasingly contentious. A survey of academic medical centers found that among infants under 12 months referred between 2009 and 2011, as few as 18% proceeded to surgery within a one- to four-year follow-up period. Of those who did see a pediatric urologist, 46% went on to have surgery, with combined clitoroplasty and vaginoplasty being the most common approach for children treated before age two.24PubMed Central. Congenital adrenal hyperplasia: current surgical management at academic medical centers in the United States The declining rate of early surgery reflects a growing emphasis on deferring irreversible procedures until the child can participate in the decision, though the evidence base for comparing early versus late surgical timing remains observational rather than comparative.25The Journal of Clinical Endocrinology & Metabolism.

The Neovaginal Microbiome
An area of research that most patients probably do not think about before surgery is what microbial community will colonize the newly created vaginal canal. It turns out the technique used to construct the neovagina strongly shapes its microbiome. Neovaginas created using penile inversion host a bacterial community most similar to that of a natal vagina with bacterial vaginosis, while neovaginas created from intestinal tissue develop a microbiome that resembles the colorectum.26PubMed Central. The microbiome of the neovagina: a systematic review and comparison of surgical techniques This matters clinically because the microbiome influences odor, discharge, susceptibility to infection, and the types of hygiene practices that will be needed long-term. Patients and clinicians are still working out what “normal” looks like for a neovaginal environment, and screening and management guidelines are evolving.
Fertility Preservation
Genital reconstruction surgery is typically irreversible, and many procedures involve removal of the gonads. For gender-affirming surgery specifically, this means losing the ability to produce eggs or sperm. Fertility preservation, through sperm cryopreservation or egg retrieval, must be discussed before surgery if the patient has any interest in future biological parenthood. A systematic review emphasized that a multidisciplinary approach involving psychologists, endocrinologists, and reproductive specialists is essential to ensure proper counseling about fertility options, ideally well before the patient reaches the surgical planning stage.27PubMed Central. Systematic review of fertility preservation options in transgender patients: a guide for plastic surgeons In practice, not every patient chooses to preserve fertility, and some prioritize surgical transition over the possibility of future biological children. But the conversation needs to happen before it becomes moot.
Secondary Procedures and Aesthetic Refinement
First-stage genital reconstruction is often just the beginning. Most patients require or choose one or more follow-up procedures to refine the result. After phalloplasty, secondary procedures commonly include glansplasty to shape the head of the neophallus, scrotoplasty to create the scrotum, and insertion of penile and testicular prostheses. After vaginoplasty, revisions may address labia shape, clitoral hood position, scar tissue, or vaginal depth. These are not signs of failure. The complexity of genital reconstruction means that staging the work and revisiting the result is standard surgical planning, not a complication.
Tissue Engineering and Future Directions
The current generation of genital reconstruction relies on repurposing tissue from other parts of the body or from other organs. Tissue engineering aims to change that by growing functional tissue from a patient’s own cells on biodegradable scaffolds. Research is underway on engineered vaginal constructs, urethral grafts, and even penile tissue, though clinical applications remain early-stage.28PubMed Central. Tissue Engineering in Gynecology The basic concept involves creating a three-dimensional scaffold, either synthetic or derived from natural materials, that is seeded with cells and encouraged to develop into tissue that could replace what current surgery borrows from the forearm, thigh, peritoneum, or intestine.29PubMed Central. Genitourinary Tissue Engineering: Reconstruction and Research Models If engineered tissue can eventually produce a self-lubricating vaginal lining or a sensate urethral tube that resists stricture formation, it would address two of the biggest unresolved limitations in the field. That possibility remains years away from routine clinical use, but the trajectory of the research gives it a plausibility that earlier speculation about lab-grown organs lacked.
