RESUMEN
Krause's corpuscles are typical of cutaneous mucous epithelia, like the lip vermillion or the glans clitoridis, and are associated with rapidly adapting low-threshold mechanoreceptors involved in gentle touch or vibration. PIEZO1 and PIEZO2 are transmembrane mechano-gated proteins that form a part of the cationic ion channels required for mechanosensitivity in mammalian cells. They are involved in somatosensitivity, especially in the different qualities of touch, but also in pain and proprioception. In the present study, immunohistochemistry and immunofluorescence were used to analyze the occurrence and cellular location of PIEZO1 and PIEZO2 in human clitoral Krause's corpuscles. Both PIEZO1 and PIEZO2 were detected in Krause's corpuscles in both the axon and the terminal glial cells. The presence of PIEZOs in the terminal glial cells of Kraus's corpuscles is reported here for the first time. Based on the distribution of PIEZO1 and PIEZO2, it may be assumed they could be involved in mechanical stimuli, sexual behavior, and sexual pleasure.

The glans clitoris has a corona; however, unlike the corona of the glans penis, the corona of the glans clitoris is practically "nonexistent" as evidenced by the noteworthy absence of its mention and depiction in anatomical and clinical sciences. Accordingly, the corona of the glans clitoris has been neglected in anatomical education and clinical practice. This report details the history regarding the anatomical terminology of the glans and identifies that descriptions of the glans penis, corona of the glans penis, and other penile structures have preceded descriptions of the homologous anatomy of the clitoris by at least a century. Today, recognition of the corona of the glans clitoris, as well as the coronal sulcus and neck of the clitoris should be commonplace. Henceforth, the corona of the glans clitoris and its related anatomy including the sulcus of the glans clitoris and neck of the clitoris should be incorporated into anatomical and clinical language, illustrations, textbooks, education, and practice. Likewise, efforts should be made to propagate knowledge regarding the corona of the glans clitoris, coronal sulcus, and neck of the clitoris to the general public. Giving names to the anatomical structures of the clitoris will undoubtedly increase the awareness of their existence which, in turn, will encourage their clinical assessment and result in decreased morbidity and mortality. Likewise, improved self-awareness of clitoral anatomy will promote self-care which is important in the prevention of disease and the promotion of optimal sexual health.

Krause corpuscles, which were discovered in the 1850s, are specialized sensory structures found within the genitalia and other mucocutaneous tissues1-4. The physiological properties and functions of Krause corpuscles have remained unclear since their discovery. Here we report the anatomical and physiological properties of Krause corpuscles of the mouse clitoris and penis and their roles in sexual behaviour. We observed a high density of Krause corpuscles in the clitoris compared with the penis. Using mouse genetic tools, we identified two distinct somatosensory neuron subtypes that innervate Krause corpuscles of both the clitoris and penis and project to a unique sensory terminal region of the spinal cord. In vivo electrophysiology and calcium imaging experiments showed that both Krause corpuscle afferent types are A-fibre rapid-adapting low-threshold mechanoreceptors, optimally tuned to dynamic, light-touch and mechanical vibrations (40-80 Hz) applied to the clitoris or penis. Functionally, selective optogenetic activation of Krause corpuscle afferent terminals evoked penile erection in male mice and vaginal contraction in female mice, while genetic ablation of Krause corpuscles impaired intromission and ejaculation of males and reduced sexual receptivity of females. Thus, Krause corpuscles of the clitoris and penis are highly sensitive mechanical vibration detectors that mediate sexually dimorphic mating behaviours.

INTRODUCTION AND HYPOTHESIS: Knowledge of clitoral neuroanatomy is critical to vulvar surgery. We sought to characterize the density and distribution of autonomic and somatic nerves supplying the clitoris. METHODS: Pelvic tissue harvested from female cadavers was sectioned axially at three anatomic levels: the proximal aspect of the clitoral body (CB), the distal CB, and the glans. The CB, glans, and the surrounding connective tissue (dorsal, lateral, and ventral) were outlined microscopically. An area containing large nerve bundles dorsal to the CB, referred to as the dorsal nerve subregion, was analyzed separately. Double-immunofluorescent staining for beta III tubulin (ßIIIT), a global axonal marker, and myelin basic protein (MBP), a myelinated nerve marker, was performed. Threshold-based automatic image-segmentation distinguished stained areas. Autonomic and somatic density were calculated as percentage of tissue stained with ßIIIT alone, and ßIIIT and MBP respectively. Comparisons were made using nonparametric Friedman tests. RESULTS: Seven cadavers, aged 22-81, were examined. Somatic (mean 4.42%, SD ± 1.97) and autonomic (2.14% ± 2.42) nerve density was highest in the dorsal nerve subregion and dorsal region at the distal CB level. Compared with the CB, somatic density was higher in proximal (0.05% ± 0.03 vs 1.27% ± 0.69, p = 0.03) and distal (0.29% ± 0.25 vs 1.09% ± 0.41, p = 0.05) dorsal regions. Somatic density was greater in the glans than in the surrounding lateral (0.78% ± 0.47 vs 0.43% ± 0.23, p = 0.03) and ventral (0.78% ± 0.47 vs 0.52% ± 0.2, p = 0.03) regions. Autonomic density was greater than somatic in all areas, except for the dorsal nerve subregion. CONCLUSIONS: Somatic and autonomic nerve density were greatest in a well-defined region dorsal to the CB. Surgical preservation of this region is critical for maintaining nerve supply to the clitoris.

BACKGROUND: Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency (21HD) can affect the in utero development of the genital anatomy of people with the 46XX karyotype. Health professionals engage parents in decision-making regarding managing genitals with this difference, including genital surgery options and patient communication. AIM: We sought to investigate parental communication with their daughters regarding clitoral size variation related to neonatal CAH. METHODS: Semistructured in-person interviews of 24 parents of chromosomal XX children with clitoral size variation attributable to a neonatal CAH diagnosis comprised 3 management categories: (1) clitoral reduction surgery (RS) (7 parents, 9 children), (2) clitoral concealment surgery (CS) (8 parents, 8 children), and no surgery on or around the clitoris (NS) (9 parents, 7 children). OUTCOMES: Four representative themes, Obvious Choice, Still Different, Parental Burden, and Ignorance Is Bliss, were common across all 3 treatment groups. RESULTS: For most parents, none of the 3 options of genital appearance alteration via clitoral reduction, clitoral concealment surgery, or avoidance of clitoral surgery ameliorated concerns, with most parents expressing an aversion to educating their child on the topic of genital differences, past treatment, or future function. CLINICAL IMPLICATIONS: Reliance on surgical treatment pathways to manage this psychosocial concern is ineffective in alleviating parental uncertainty without the application of psychosocial interventions. STRENGTHS AND LIMITATIONS: This was a qualitative study but was limited to parents of children with a specific genital difference, without direct exploration of parental values regarding the clitoris or the application of adequate psychosocial care. CONCLUSION: Healthcare services must have an impact on parental ability to engage in essential communication with their children in cases such as clitoral size variation related to neonatal CAH. Improved communication skills allow parents to engage in more genuine decision-making and adapt to enduring genital reality, including possible future sexual challenges for their adult child, without resorting to burdensome strategies focused on attempts to perpetuate a benevolent ignorance.

BACKGROUND: Keratin pearls are foci of central keratinization within concentric layers of squamous cells that can form under the clitoral prepuce and cause pain (clitorodynia); in-office removal of keratin pearls may reduce clitoral pain and improve sexual function. AIM: This study aims to investigate clitoral pain and sexual function in women with partial clitoral phimosis and keratin pearls before and after in-office lysis of clitoral adhesions with keratin pearl excision (LCA-KPE). METHODS: A pre-post interventional study evaluated patients who underwent LCA-KPE between January 2017 and February 2023 in 2 metropolitan gynecology clinics specializing in vulvar pain. Patients presenting with keratin pearls and partial clitoral phimosis identified through retrospective chart review were asked to complete postprocedure questionnaires and provide subjective responses on clitoral discomfort, sexual function, sexual distress, and their experience with in-office LCA-KPE. Bivariate analyses with paired t tests were conducted to determine the effect of LCA-KPE. Qualitative data were analyzed with thematic coding. OUTCOMES: An 11-point pain visual analog scale was utilized to determine pre- and postprocedure clitoral discomfort and difficulty with orgasm. Female sexual dysfunction was measured with the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised. RESULTS: A total of 32 of 74 patients who met inclusion criteria completed postprocedure surveys (43% response rate). Mean clitoral pain for respondents was 6.91 at baseline and 2.50 after LCA-KPE (P < .001). Mean difficulty with orgasm was significantly decreased from 5.45 at baseline to 3.13 after LCA-KPE (P < .001). Participants had a mean FSFI total score of 17.68 after treatment compared with a mean total baseline FSFI of 12.12 (P = .017). The mean FSFI score for pain was 2.43 at follow-up compared with 1.37 at baseline (P = .049). There was no significant difference in the mean Female Sexual Distress Scale-Revised score before vs after the procedure (P = .27). Qualitative themes described the procedure as painful but worthwhile, with 77% of participants reporting the overall experience as positive. Recurrence rate overall was 28%, with a median of 2 repeat procedures. CLINICAL IMPLICATIONS: Recognizing keratin pearls as a structural cause of clitoral pain and offering in-office treatment is an important tool in addressing clitorodynia and improving sexual function. STRENGTHS AND LIMITATIONS: This is the largest study to date documenting the occurrence, identifying associated pain conditions, and evaluating procedural outcomes for clitoral keratin pearls. This study was limited by a relatively small sample size. CONCLUSION: In-office LCA-KPE significantly reduced clitoral discomfort and difficulty with orgasm.

The human penile and clitoral development begins from a morphologically indifferent genital tubercle. Under the influence of androgen, the genital tubercle forms the penis by forming a tubular urethra within the penile shaft. Without the effect of the androgen, the genital tubercle differentiates into the clitoris, and a lack of formation of the urethra within the clitoris is observed. Even though there are similarities during the development of the glans penis and glans clitoris, the complex canalization occurring along the penile shaft eventually leads to a morphological difference between the penis and clitoris. Based on the morphological differences, the main goal of this study was to define the vascular and neuronal anatomy of the developing penis and clitoris between 8 and 12 weeks of gestation using laser scanning confocal microscopy. Our results demonstrated there is a co-expression of CD31, which is an endothelial cell marker, and PGP9.5, which is a neuronal marker in the penis where the fusion is actively occurring at the ventral shaft. We also identified a unique anatomical structure for the first time, the clitoral ridge, which is a fetal structure running along the clitoral shaft in the vestibular groove. Contrary to previous anatomical findings which indicate that the neurovascular distribution in the developing penis and clitoris is similar, in this study, laser scanning confocal microscopy enabled us to demonstrate finer differences in the neurovascular anatomy between the penis and clitoris.

BACKGROUND: Lichen sclerosus (LS) is a chronic inflammatory disorder, presenting with pruritis and hypopigmentation of the vulvar and anogenital skin. LS presenting as a peri-clitoral mass has not been previously described. CASE: A 5-year-old patient with vulvar pruritis and ultrasound showing a homogenous mass was referred for suspected clitoromegaly with normal labs. Examination demonstrated a prepubertal patient with a mobile, soft, peri-clitoral mass and surrounding hypopigmentation consistent with LS. The cyst was excised surgically; pathology revealed an epidermal inclusion cyst. Postoperatively, she began using topical steroids for LS with symptom resolution. CONCLUSION: Thorough workup of clitoromegaly negative for hormonal causes requires further investigation to determine an alternative etiology of the mass. We suspect that inflammatory changes of LS and pruritus resulted in the peri-clitoral inclusion cyst.

OBJECTIVE: To compare the collagen, elastic fibers, and smooth muscle content of the clitoris and the glans penis in young adults. MATERIALS AND METHODS: The clitoris and the glans penis of six women and six men (mean age 25±3) who died as a result of accidents were excised. The samples were placed under a formaldehyde solution and histologically processed. Masson's trichrome and Weigert's resorcin-fuchsin stain was used to highlight the elastic fibers, smooth muscle, and collagen. Stereological analysis was conducted in 5 random fields of 5 slides for each sample. For statistical analysis, the unpaired t-test was used to compare values between groups, and a value of P<0.05 was considered as significant for all analyses. RESULTS: Stereology revealed a mean smooth muscle content of 35.84±6.46% and 31.64±4.74% for the clitoris and glans penis, respectively, while it also revealed collagen content of 26.11±7.41% and 28.44±3.55% and elastic fibers content of 24.12±4.34% and 30.97±6.13% for the clitoris and glans penis, respectively. The statistical analysis showed no significant differences between them. CONCLUSION: Regardless of anatomical differences, the volumetric density of collagen, elastic fibers, and smooth muscle were similar for the clitoris and glans penis in young adults, a feature possibly explained by their embryology.

BACKGROUND: The clitoris has long been ignored in medical literature and teaching, with the first paper describing its anatomy only published in 1993. It is essential that those working in women's health understand the anatomy of this important female sexual organ. AIMS: The aim of this study was to assess the level of knowledge of the anatomy of the clitoris across five cohorts in a busy teaching maternity hospital in Ireland. MATERIALS AND METHODS: A questionnaire was devised, asking ten consultants, ten non-consultant hospital doctors (NCHDs), ten midwives, ten midwifery students and ten medical students to name the anatomical parts of a 3D model of the clitoris. RESULTS: None of the 50 respondents could name all five labelled parts of the clitoris, and 38 of respondents could not correctly name one anatomical part. CONCLUSIONS: It is evident that there is a lack of knowledge of the anatomical parts of the clitoris among the medical staff included in this study. This reflects a lack of adequate teaching in this area in both past and recent years. Despite this, we acknowledge that women's health and sexual health awareness is improving all of the time, and we hope that this study can highlight the need for reformed teaching in this area.

An understanding of ranges in clitoral anatomy is important for clinicians caring for patients including those who have had female genital mutilation, women seeking genital cosmetic surgery, or trans women seeking reconstructive surgery. The aim of this meta-analysis is to investigate the ranges in clitoral measurements within the literature. A meta-analysis was performed on Ovid Medline and Embase databases following the PRISMA protocol. Measurements of clitoral structures from magnetic imaging resonance, ultrasound, cadaveric, and living women were extracted and analyzed. Twenty-one studies met the inclusion criteria. The range in addition to the average length and width of the glans (6.40 mm; 5.14 mm), body (25.46 mm; 9.00 mm), crura (52.41 mm; 8.71 mm), bulb (52.00 mm; 10.33 mm), and prepuce (23.19 mm) was calculated. Furthermore, the range and average distance from the clitoris to the external urethral meatus (22.27 mm), vagina (43.14 mm), and anus (76.30 mm) was documented. All erectile and non-erectile structures of the clitoris present with substantial range. It is imperative to expand the literature on clitoral measurements and disseminate the new results to healthcare professionals and the public to reduce the sense of inadequacy and the chances of iatrogenic damage during surgery.

Female genital mutilation (FGM) was seen in 30 countries, especially in Africa and also in Asia and the Middle East. According to WHO data, Somalia is where FGM is performed most frequently. Our study aimed to evaluate the recordings of patients with FGM who were diagnosed with a traumatic clitoral cyst. We identified the clitoral cyst cases between February 2015 and August 2020. We collected clinical, surgical, sociodemographic, and histopathological details such as age, marital status, patient resume, age at which FGM was performed, complaints, size of the cyst consultation reasons, FGM procedural long-term complications, sexual function, husband polygamic relationship status, and histological findings. A total of 21 patients diagnosed with clitoral cysts were included in the study. The technique was easily applied in every patient, and the cysts were removed intact, except in 2 patients. There were no intraoperative complications; only minimal bleeding was seen. Except for one patient, all had unilocular cysts, and the final pathological examination revealed an epidermal inclusion cyst. We observed a neuroma developed due to genital trauma due to FGM in one of our patients. Female circumcision and its consequences are not familiar to many healthcare professionals in the developed world. We want to increase awareness of female circumcision and its long-term complication of clitoral cysts among healthcare professionals worldwide.

In the last two decades, genital transplants have emerged as another type of quality-of-life transplants. Successful allogenic transplantations of the uterus, ovary, testicle, and penis have all been reported. Yet, there is no discussion of clitoris transplantation in the medical literature, mass media, and everywhere else I searched. This surgery could be used for cisgender women who have a clitoral injury or disease or who have undergone female genital cutting. I examine the gender norms regarding sexuality and reproduction to show how they shape surgical advancements. My point in this paper is not to take a normative position on status of current genital transplantations. Rather, I highlight that their existence is due, at least in part, because they align with dominant gender norms: penis and testicle transplantations reinforce the importance of men's virility and the existence of "normal" male genitalia, whereas uterus and ovary transplantations uphold the conflation of women and reproduction and the strong valuing of women's fertility. That medical advances reflect cultural values is not a new claim. What is new in this paper is the discussion of how sexism norms-regarding the invisibility of the clitoris and the devaluing of women's sexual pleasure- has engendered various types of genital transplants, but not clitoris transplantation.

Background and objectives: We herein reported ten, female neonates with transient clitoral preputial edema, which was mistaken for clitoromegaly. Although it is well known that the clitoris is prominent in premature, female neonates, there are as of yet no reports of clitoral preputial edema in full-term neonates. The present study was conducted to clarify the clinical course of clitoral preputial edema. Methods: Seventeen, Japanese patients aged < 6 months with suspected clitoromegaly were enrolled, and their clinical course was analyzed retrospectively. Clitoral preputial edema was defined by 1) a normal clitoral glans despite edema; and 2) the absence of established differences of sexual development, such as 21-hydroxylase deficiency. Results: Ten of the 17 patients with suspected clitoromegaly had clitoral preputial edema; eight of the ten patients were full-term, and the remaining two were preterm neonates. The median age at the first visit was 8 days. Edema of the labia minora and labia majora, rugosity of the labia majora, and hymenal polyps often accompanied the clitoral preputial edema. Seven patients were examined at our division during the neonatal period, and three patients were examined in the post-neonatal period. Age at reduction of the clitoral width to < 7 mm ranged from 8 to 74 days in four of the seven neonatal patients. In the three post-neonatal patients, age to reduction in the clitoral width ranged from 107 to 243 days. Conclusions: Transient clitoral preputial edema is often mistaken for clitoromegaly. The key to diagnosing clitoral preputial edema lies in its characteristic appearance and improvement course.

INTRODUCTION: The construction of the labia minora from preputial tissues in uncircumcised patients and the preservation of the sensitivity of the labia minora are not new ideas. However, evidently, this technique is designed for uncircumcised cases.There is no preputial tissue in the circumcised population. However, this tissue, whose inner and outer layers have different structures and appearances, is critical in the construction of the labia minora. Instead, there is an area of reepithelialization and reinnervation that heals secondarily or is closed primarily, depending on the circumcision. Also, this new skin area is devoid of the natural oily secretions of the prepuce. In addition, the removal of preputial tissue in circumcised individuals may cause uncertainty in terms of vascularity or sensitivity. In this study, we share our clinical experience regarding large labia minora creation (with preserved flap circulation without vaginal reconstruction concerns) and the use of most of the urethra as a mesh graft in the circumcised population. MATERIALS AND METHODS: Between 2010 and 2022, 19 cases were operated on with this technique. All cases were primary interventions for male-to-female sex reassignment. Because this design of the sensitive inner surface of the labia minora, which ensured vascular safety, was not found in the literature, the design was named "butterfly flap" because of its shape. EVALUATION OF SENSATION: The area corresponding to both wings of the butterfly flap was evaluated with the Semmes Weinstein Monofilament test, with the patient's eyes closed, in the preoperative period. Likewise, the sensitivity of the inner surface of the labia minora in the first year of 10 patients who were able to attend follow-up clinical examination was evaluated with the same method. RESULTS: In our study, a clitoris and a labia minora with sensory innervation were obtained by elevating the superior 180-degree area of the neurovascular bundle surrounding the penis and using the butterfly flap we prepared in the area fed by this bundle. Fourteen cases stated that the sensation of the newly formed labia minora was erogenous and different from the tactile sensation on the body of the penis.

Congenital adrenal hyperplasia (CAH) is most often caused by adrenal deficiency of 21-hydroxylase (21-OH). The resulting increase in androgens can cause clitoromegaly in fetuses with XX chromosomes. 21-OH CAH is the most common reason for cosmetic clitoroplasty in childhood. "Nerve-sparing" (NS) clitoral reduction surgeries are described as offering optimal cosmesis, while sparing sensation and nerve function. The methods used to demonstrate NS surgery efficacy, however, such as electromyography and optical coherence tomography, do not evaluate the small-fiber axons that comprise the majority of axons in the clitoris and that transduce sexual pleasure. Although some data show sparing of a portion of the main dorsal nerve trunk of the clitoris, the overall neurobiological consequences of elective clitoral reductions have received little attention. NS surgeries remove dorsal nerve branches that transduce sexual sensation, as well as the corpora cavernosa and cavernous nerve, which provide clitoral autonomic function. While most outcome studies focus on surgeons' perceptions of cosmetic results, studies that assess small-fiber function indicate significant nervous system and sexual impairment. Studies assessing children's clitoral function after surgery with vibrational testing have been ethically condemned. Decades of advocacy against medically unnecessary childhood genital surgeries have highlighted the subsequent physical and psychological harm. Recent studies with CAH patients indicate gender diversity and a lower prevalence of female gender identification than is often cited to justify feminizing surgery. The most effective and ethical NS technique for CAH may be acceptance of gender, sexual, and genital diversity as the infant develops into childhood, adolescence, and adulthood.

INTRODUCCIÓN: El clítoris es una de las estructuras vulvares menos examinadas, pese a su relevancia en la vida sexual y sus importantes relaciones anatómicas. Las adherencias del capuchón del clítoris han sido descritas y clasificadas según la exposición del glande, siendo relacionadas con trastornos del deseo sexual. La inervación del clítoris depende de raíces de S3-S4, siendo posible que síntomas frecuentes del piso pélvico tengan relación con esta condición. Realizamos un análisis retrospectivo de pacientes de policlínico de piso pélvico entre noviembre de 2021 y abril de 2022. Se incluyeron 100 pacientes con adherencias al ingreso. RESULTADOS: Promedio de edad 45,8 ± 15,5 años. Las adherencias fueron el 19% leves, el 62% moderadas y el 18% graves. Los principales síntomas eran mal vaciado vesical (38%), dolor (28%), disfunción sexual (39%) y síntomas irritativos vesicales (43%); solo una paciente fue asintomática. El área visible promedio del clítoris era de 20,7 ± 13,7 mm2. CONCLUSIONES: Las adherencias del capuchón del clítoris son un hallazgo común, muchas veces no diagnosticadas, por lo que su evaluación debe ser parte de la exploración física. Pueden asociarse a sintomatología de piso pélvico.
INTRODUCTION: The clitoris is one of the least examined vulvar structures despite its relevance in sexual life and important anatomical relationships. Clitoral hood adhesions have been described in the literature, classified based on glans exposure, and related to sexual desire disorders. The innervation of the clitoris depends on the roots of S3-S4, and frequent pelvic floor symptoms may be associated with this condition. We retrospectively analyzed the clinical record of patients admitted to a pelvic floor clinic between November 2021 and April 2022. One hundred patients with adhesions at the time of admission were registered. RESULTS: Average 45.8 ± 15.5 years. Clitoral hood adhesions were mild (19%), moderated (62%), or severe (18%). The main symptoms were voiding dysfunction symptoms (38%), pain (28%), sexual dysfunction (39%), and irritative bladder symptoms (43%); only one patient was asymptomatic. The visible area of the clitoris was 20.7 ± 13.7 mm2. CONCLUSIONS: Adhesions of the clitoral hood are often undiagnosed, and its analysis should be part of the physical exam. Clitoral hood adhesions could be associated with pelvic floor symptoms.

OBJECTIVE: To describe our technique for performing gender affirming graft only vaginoplasty. METHODS: In graft only vaginoplasty, penile skin is used only for the external genitals, and the entire vaginal canal is created from a full thickness skin graft. The inner scrotum is excised and used as a skin graft to line the vaginal canal. The outer scrotum is left in place then moved medially to form the labia majora. The penile skin and Dartos fascia are incised dorsally and ventrally then advanced to the posterior perineum to become the labia minora. The glans clitoris is constructed from a W-shaped dorsally-based portion of the glans penis, and the clitoral hood is constructed from the distal 2-3 cm of penile shaft skin. The posterior wall of the introitus is formed from a posterior perineal flap. RESULTS: The patient presented here is a 26-year-old transgender woman with marked and sustained gender incongruence. She is circumcised, has typical penile length, scrotal contents are normal, and all hair has been removed on the scrotum and perineum. She underwent graft only vaginoplasty, as shown in the accompanying video. CONCLUSION: Gender affirming graft only vaginoplasty allows for construction of the vaginal canal from a full thickness skin graft, and construction of external genitals from penile and scrotal skin. Advantages of this approach include availability of more tissue for construction of the external genitals and an external skin to graft anastomosis. The procedure is modified slightly when the patient has a small scrotum, short penis, or is uncircumcised.
