This complex reconstructive surgery involves the removal of the penis, testicles, and scrotum. The existing tissue from the genital area is then carefully rearranged to form a vaginal canal, also known as a neovagina, and external female genitalia, referred to as the neovulva, which includes the labia and clitoris. The goal of this surgery is to create genitalia that are congruent with the individual's gender identity. It is important to note that a related procedure called vulvoplasty exists, which focuses on creating the external female genitalia with a shallow or absent vaginal canal. This option is suitable for individuals who do not desire penetrative intercourse. The consistent emphasis across medical literature on the creation of both internal and external female genitalia highlights the comprehensive reconstructive nature of vaginoplasty. Furthermore, the distinct availability of vaginoplasty with a canal versus vulvoplasty without one indicates that surgical approaches can be tailored to meet the diverse needs and desires of individuals seeking gender affirmation. There are three primary surgical techniques employed to perform vaginoplasty for individuals assigned male at birth: penile inversion, peritoneal pull-down (PPT), and colo-vaginoplasty. Penile inversion is a technique that utilizes the skin of the penis and scrotum to construct the neovagina. Peritoneal pull-down (PPT) vaginoplasty involves using the peritoneum, which is the lining of the abdominal cavity, to form part or all of the neovaginal canal. Finally, colo-vaginoplasty utilizes a segment of the colon, or large intestine, to create the neovagina. The existence of these three distinct techniques suggests that the surgical approach is often tailored to the individual's specific anatomy, desired outcomes, and other factors. ## **Penile Inversion Vaginoplasty** ### **Surgical Technique** Penile inversion vaginoplasty is widely recognized as the gold standard technique for vaginoplasty in gender affirmation surgery. The procedure creates a vaginal vault between the rectum and urethra. Inverted penile skin primarily lines this newly formed vaginal canal, while scrotal skin typically forms the labia majora. The clitoris is constructed from the penis glans, preserving nerve endings for tactile sensation. During the procedure, erectile tissue is removed to prevent unwanted narrowing of the vaginal opening or protrusion during arousal. The urethra is shortened and repositioned to a typical female anatomical location. When penile skin is insufficient for adequate vaginal depth, surgeons may use skin grafts from the scrotum, abdomen, thigh, or hip. To prevent hair growth inside the neovagina, pre-operative hair removal using electrolysis or laser is strongly recommended for the scrotum and perineum, though some modified techniques may reduce this requirement. The surgery typically takes two to five hours. Post-operatively, a vaginal stent or packing remains inside the neovagina for five to seven days to maintain shape and promote healing. Regular vaginal dilation is crucial for maintaining depth and width and preventing stenosis. Some individuals may require a secondary labiaplasty procedure to refine the appearance of the labia. The complexity of penile inversion vaginoplasty, with its various steps and potential modifications, centers on utilizing existing genital skin. Pre-operative hair removal and diligent post-operative dilation are essential for successful outcomes, while secondary procedures may be necessary to achieve optimal aesthetic results. ### **Benefits** Penile inversion vaginoplasty offers several potential benefits for individuals assigned male at birth seeking gender affirmation. A significant advantage is the utilization of existing tissue from the penis and scrotum, contributing to a more natural appearance and feel of the neovagina. This technique allows for natural-feeling sensation in the neoclitoris through careful preservation of the neurovascular bundle during surgery. For many individuals, this procedure enables receptive vaginal intercourse and is typically performed as a single-stage surgery, addressing all primary components in one operation. Penile inversion vaginoplasty is well-researched, with extensive literature documenting outcomes and potential complications. Studies report high patient satisfaction regarding functionality, aesthetic appearance, and ability to achieve orgasm. The procedure can significantly alleviate gender dysphoria, leading to increased self-esteem and confidence. Typical vaginal depth achieved ranges from approximately 5 to 7 inches (12 to 18 centimeters), generally sufficient for penetrative sexual activity. Compared to techniques using non-genital skin grafts, this method may have a lower tendency for neovaginal contraction over time and reduced risk of vaginal prolapse. The benefits largely stem from using the individual's own genital tissue, contributing to natural outcomes in sensation, appearance, and function. High patient satisfaction rates and extensive research support make penile inversion vaginoplasty a frequently chosen option for gender affirmation surgery. ### **Physical Costs and Risks** While penile inversion vaginoplasty is generally considered a safe and effective procedure, it is associated with potential physical costs and risks. Complications may include bleeding, infection at the surgical site, tissue death (necrosis) of the skin or clitoris, and rupture of the incision sutures. Patients might experience urinary retention, vaginal prolapse, or the formation of fistulas—abnormal connections between the neovagina and other organs such as the rectum or bladder. Wound healing complications can include dehiscence (separation of the surgical wound edges) and hypergranulation (excessive growth of healing tissue). A significant risk associated with this procedure is vaginal stenosis—narrowing of the vaginal canal—which requires consistent, long-term dilation to maintain adequate depth and width. Some patients may find that achieving desired vaginal depth is limited by the amount of available penile and scrotal skin, occasionally necessitating skin grafts from other body areas. Urinary complications can also occur, including spraying urine stream, post-urination dribbling, narrowing of the urethral opening, urinary incontinence, and urethral strictures. Aesthetic concerns such as labial asymmetry may require additional revision surgery. Insufficient pre-operative hair removal from the scrotum and perineum can result in hair growth inside the neovagina, causing discomfort and hygiene issues. Other potential complications include nerve damage leading to altered sensation or chronic pain, hematoma formation, vaginal discharge, and bleeding during initial recovery. Though rare, rectal injury during surgery is also a risk. While generally safe, penile inversion vaginoplasty carries both typical surgical risks and technique-specific complications, highlighting the importance of diligent post-operative care—particularly adherence to the dilation schedule—to help mitigate certain complications. ## **Peritoneal Pull-Down (PPT) Vaginoplasty** ### **Surgical Technique** Peritoneal pull-down (PPT) vaginoplasty represents a more recent approach in the field of gender affirmation surgery for individuals assigned male at birth. While relatively new in this context, the technique has its origins in gynecological procedures, specifically the Davydov procedure, which has been used to create vaginas for individuals born with congenital vaginal agenesis. The core of the PPT technique involves utilizing the peritoneum, a thin membrane that lines the abdominal cavity, to construct the neovaginal canal. This procedure is frequently performed using laparoscopic techniques, which involve inserting a laparoscope and specialized surgical instruments through small incisions in the abdomen. In some instances, robotic assistance may be employed to enhance precision and visualization during the procedure. During the surgery, the peritoneum is carefully dissected and pulled down into the space located between the rectum and the urethra or prostate gland. Similar to the penile inversion technique, the external genitalia, including the labia and clitoris, are typically formed using the existing skin from the penis and scrotum. To ensure the neovagina is separate from the abdominal cavity, the top of the newly created canal is closed off by suturing the peritoneal lining. In some cases, surgeons may utilize a combination of the PPT technique with elements of penile inversion, creating a hybrid approach. One potential advantage of PPT vaginoplasty is that it may require less extensive pre-operative hair removal for the lining of the vaginal canal, as the peritoneum itself is hairless. However, pre-operative hair removal is still generally necessary for the tissues used to construct the external vulvar structures. The duration of a primary PPT vaginoplasty surgery is typically around 5 hours, and the hospital stay can range from 2 to 5 days. Post-operative vaginal dilation is still a crucial part of the recovery process to maintain the depth and width of the neovagina, although some sources suggest that the frequency of dilation might be less compared to penile inversion. The adoption of PPT vaginoplasty in gender affirmation surgery reflects a move towards exploring alternative tissue sources that may offer unique benefits, and the use of minimally invasive techniques like laparoscopy underscores the ongoing advancements in surgical approaches. The relative novelty of this technique in the context of gender affirmation means that the long-term outcomes are still being studied. ### **Benefits** Peritoneal pull-down (PPT) vaginoplasty offers several potential benefits for individuals seeking gender affirmation surgery. One notable advantage is the potential for achieving greater vaginal depth compared to the penile inversion technique, particularly in individuals who may have limited penile skin available. The peritoneal lining itself may provide some degree of natural lubrication to the neovagina. However, it is important to note that some medical professionals indicate that this natural lubrication might not be sufficient for all individuals, and the use of additional lubricants may still be necessary for dilation and sexual activity. A significant benefit of the PPT technique is that the peritoneal lining is naturally hairless, eliminating the risk of hair growth inside the neovagina, a potential concern with penile inversion. PPT vaginoplasty can be a particularly suitable option for individuals who have insufficient penile skin due to prior surgeries or the use of puberty blockers during adolescence. Some sources suggest that there may be less need for post-operative douching compared to other vaginoplasty techniques. Additionally, PPT vaginoplasty may carry a lower risk of complications compared to colo-vaginoplasty, another alternative technique. This procedure can be utilized for both primary vaginoplasty and as a revision surgery to increase the depth of a previously created neovagina. The fact that PPT vaginoplasty is often performed laparoscopically, a minimally invasive approach, can lead to smaller surgical scars and potentially a faster recovery period for patients. The peritoneal lining also possesses some degree of natural elasticity, which may contribute to the functionality and comfort of the neovagina. The key advantages of PPT vaginoplasty appear to be the potential for increased vaginal depth, the possibility of some natural lubrication, and the absence of hair growth within the neovagina, addressing some of the limitations associated with penile inversion. However, the extent of self-lubrication provided by the peritoneal lining seems to vary among individuals. ### **Physical Costs and Risks** While peritoneal pull-down (PPT) vaginoplasty offers several advantages, it also carries potential physical costs and risks that individuals considering this procedure should be aware of. These include all the risks typically associated with penile inversion vaginoplasty. Additionally, because PPT vaginoplasty often involves a laparoscopic approach to access the abdomen, further risks include potential injury to intra-abdominal organs, development of ileus (a temporary lack of bowel movement), herniation at incision sites, and other complications related to abdominal surgery. The procedure also carries risks of flap failure, where the peritoneal flap does not heal properly, and potential stenosis (narrowing) of the neovagina. Specific intra-abdominal complications reported following PPT vaginoplasty include hematomas (blood collections), abscesses (pus collections), small bowel obstruction, and internal hernias. Given that PPT vaginoplasty is a relatively newer technique in gender affirmation surgery, there is limited long-term data regarding outcomes and potential complications. Some individuals experience bothersome vaginal discharge from the peritoneal lining, necessitating the use of panty liners. As with other vaginoplasty techniques, there is risk of injury to adjacent pelvic organs during surgery, including the urethra, bladder, or rectum. Additional potential complications include pelvic abscess, recurrent small bowel obstruction, and incarcerated internal hernias at either the peritoneal flap closure site or harvest site. While offering significant benefits, PPT vaginoplasty introduces risks inherent to abdominal surgery, and the limited long-term data available necessitates careful consideration and thorough discussion with an experienced surgeon. ## **Colo-Vaginoplasty** ### **Surgical Technique** Colo-vaginoplasty is a surgical technique that uses a segment of the colon, typically the sigmoid colon, to create a neovagina for individuals assigned male at birth seeking gender affirmation. This method is often considered when penile inversion vaginoplasty isn't feasible due to insufficient penile skin. The procedure typically involves two surgical stages: first, creating a tunnel in the perineal area to form the space for the neovagina, and second, harvesting a segment of the colon which is then grafted into this space. However, some surgeons perform the entire procedure in a single stage. Accessing and removing the necessary colon segment requires an abdominal incision. Some centers use laparoscopic techniques, which involve smaller incisions and specialized instruments. Once the colon segment is harvested with its blood supply intact, it's moved to the perineal area and connected to the previously created vaginal tunnel. To maintain normal digestive function, the remaining portions of the colon are reconnected through anastomosis. The external genitalia, including the labia and clitoris, are constructed using remaining skin from the penis and scrotum, similar to the penile inversion technique. Before undergoing colo-vaginoplasty, patients typically require bowel preparation to thoroughly cleanse the colon. The hospital stay following this procedure is generally longer compared to other vaginoplasty techniques, often lasting around 7 days or more for adequate monitoring and recovery. The overall recovery period can extend over several months, and patients may need to follow specific dietary restrictions during the initial post-operative phase as the digestive system heals. Post-operative vaginal dilation maintains the depth and width of the neovagina, though some sources suggest it might be less extensive or required for a shorter duration compared to penile inversion. Colo-vaginoplasty is a more involved procedure requiring major abdominal surgery, making it typically a secondary option when other techniques aren't suitable or when achieving significant vaginal depth is a primary goal. The bowel preparation requirement and extended recovery period are important considerations for individuals exploring this surgical approach. ### **Benefits** Colo-vaginoplasty offers several potential benefits for individuals assigned male at birth seeking gender affirmation surgery. One of the primary advantages of this technique is the ability to achieve significant vaginal depth, often exceeding that of penile inversion, with reported depths of 8 to 10 inches or even more. The lining of the colon naturally produces mucus, resulting in self-lubrication of the neovagina, which can enhance comfort and functionality. Colo-vaginoplasty can be particularly beneficial for patients who have limited penile tissue available or who have undergone previous vaginoplasty procedures that were not successful in achieving adequate depth. Some medical literature suggests that there may be less need for extensive long-term vaginal dilation following colo-vaginoplasty compared to the penile inversion technique. This procedure can provide a durable and functional neovagina, capable of withstanding sexual activity. Patient satisfaction rates with colo-vaginoplasty are reported to be high, particularly in terms of the functionality and aesthetic appearance of the neovagina. Unlike penile inversion, colo-vaginoplasty does not typically require pre-operative electrolysis of the colon segment that will be used to create the neovagina. Due to the thick-walled nature and larger diameter of the colon segment used in this procedure, there may be a lower risk of bleeding after sexual intercourse compared to techniques utilizing thinner skin grafts. The primary advantages of colo-vaginoplasty lie in its ability to provide significant vaginal depth and natural lubrication, making it a valuable option for individuals who prioritize these aspects or for whom other techniques may not be suitable. Its utility in revision surgeries further underscores its importance in the spectrum of vaginoplasty techniques. ### **Physical Costs and Risks** While colo-vaginoplasty offers significant benefits, it also carries a higher risk of major complications compared to penile inversion vaginoplasty, primarily due to its involvement of the digestive system. One of the most serious potential risks is a bowel anastomotic leak, where the connection between the remaining parts of the colon fails, leading to infection and potentially requiring a temporary stoma (an opening in the abdomen to divert stool). There is also a risk of developing an intra-abdominal infection or abscess following the surgery. Patients undergoing colo-vaginoplasty typically experience a longer recovery period and a more extended hospital stay compared to other vaginoplasty techniques. A common issue reported by individuals with a neovagina created from colon tissue is excessive mucus discharge, which can sometimes have an odor and may necessitate the consistent use of absorbent pads. There is also a potential risk of diversion colitis, which is inflammation of the remaining portion of the colon that is no longer in the normal flow of stool. Neovaginal stenosis (narrowing) or prolapse (descent) are also possible complications. As with any surgical procedure in the pelvic area, there is a risk of injury to adjacent organs such as the urethra, bladder, or rectum during the surgery. The development of a fistula, an abnormal connection between the neovagina and another organ, is also a potential complication. Patients may also be at risk of developing blood clots, such as deep vein thrombosis or pulmonary embolism, following this type of major surgery. Bowel-related issues like constipation or other changes in bowel habits can also occur. In rare cases, there has been a reported long-term risk of colon carcinoma developing in the segment of colon used to create the neovagina. The risks associated with colo-vaginoplasty are primarily linked to the involvement of the bowel, and while the procedure offers significant benefits in terms of depth and lubrication, the potential for serious complications underscores the importance of careful patient selection and a thorough understanding of these risks. ## **Comparative Analysis: Penile Inversion vs. PPT vs. Colo-Vaginoplasty** The three main types of vaginoplasty for individuals assigned male at birth offer distinct advantages and disadvantages. The following table provides a summary of the key features, benefits, and risks associated with each technique: | | | | | |---|---|---|---| |**Feature**|**Penile Inversion**|**PPT Vaginoplasty**|**Colo-Vaginoplasty**| |Primary Tissue Source|Penile and scrotal skin|Peritoneum (abdominal lining)|Sigmoid colon (large intestine)| |Typical Vaginal Depth|5-7 inches (12-18 cm)|Potentially greater than penile inversion|8-10 inches or more (20+ cm)| |Natural Lubrication|No|Potential for some|Yes| |Need for Pre-op Hair Removal (canal)|Highly recommended|Less extensive|No| |Major Benefits|Natural feel, sensation, well-researched|Greater depth potential, no hair growth in canal|Significant depth, natural lubrication| |Key Physical Costs/Risks|Stenosis, depth limitations, hair growth|Abdominal surgery risks, unknown long-term outcomes|Bowel complications, longer recovery, mucus discharge| |Typical Surgical Time|2-5 hours|~5 hours (primary)|5-6 hours| |Typical Hospital Stay|3-5 days|2-5 days|7+ days| |Need for Dilation|Crucial and long-term|Required, potentially less frequent|May be less extensive| |Suitability for Limited Penile Skin|May require skin grafts from other areas|Good option|Good option| Understanding the trade-offs between vaginoplasty techniques is essential when making this important decision. Penile inversion, the most established method, utilizes familiar genital tissue that typically provides excellent sensation and aesthetic results. Its limitations include potential restrictions in vaginal depth and the requirement for rigorous post-operative dilation to prevent narrowing. Peritoneal pull-down (PPT) vaginoplasty offers an alternative approach using the peritoneum, potentially achieving greater depth while eliminating the risk of unwanted hair growth within the neovagina. However, as a relatively recent technique in gender-affirming care, comprehensive long-term outcome data remains limited, and patients must consider the inherent risks of abdominal surgery. Colo-vaginoplasty distinguishes itself by creating the most substantial vaginal depth and providing natural lubrication, significantly enhancing both functionality and comfort. This benefit comes with important considerations: the procedure requires more invasive abdominal surgery, carries elevated risks of bowel-related complications, involves a lengthier recovery period, and may result in excessive mucus discharge. ## **Conclusion** Vaginoplasty for individuals assigned male at birth offers three main surgical approaches, each with distinct characteristics. Penile inversion, the established standard, creates functional and aesthetically pleasing results using existing genital tissue. The newer peritoneal pull-down technique utilizes abdominal lining to potentially achieve greater depth with some natural lubrication. Colo-vaginoplasty employs colon tissue to create significant depth and self-lubrication. The optimal technique for any individual depends on their unique anatomy, surgical goals, risk tolerance, and medical guidance. Prospective patients should engage in comprehensive consultations with experienced surgeons to thoroughly understand each option and determine which approach best aligns with their specific needs. The field of gender-affirming surgery continues to advance, with ongoing refinements in surgical techniques and improved understanding of long-term outcomes. These developments expand options and enhance results for transgender individuals seeking genital confirmation surgery. ### References 1. www.hopkinsmedicine.org, accessed April 30, 2025, [https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/vaginoplasty-for-gender-affirmation#:~:text=What%20is%20vaginoplasty%3F,genitalia)%2C%20including%20the%20labia.](https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/vaginoplasty-for-gender-affirmation#:~:text=What%20is%20vaginoplasty%3F,genitalia\)%2C%20including%20the%20labia.) 2.
