Beyond the tip of the iceberg: A meta-analysis of the anatomy of the clitoris.

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.

A long-term complication of clitoral cyst after female genital mutilation.

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.

No clitting! We need to talk about clitoris transplantation.

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.

Clitoral preputial edema can be mistaken for clitoromegaly: a clinical analysis of ten cases.

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.

Construction of Sensitive Labia Minora-Clitoris-Clitoral Hood Complex in Sex Reassignment Surgery in Circumcised Populations: Butterfly Flap.

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.

Neurological Considerations for "Nerve-Sparing" Cosmetic Genital Surgeries Performed on Children with XX Chromosomes Diagnosed with 21-Hydroxylase Congenital Adrenal Hyperplasia and Clitoromegaly.

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.

Adherencias del capuchón del clítoris al glande: una condición poco estudiada y poco examinada / Clitoral hood adhesions to the glans penis: an understudied and under-examined condition

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.

Standardized Photography of Female Genitalia and Anatomical Evaluations.

BACKGROUND: Standardized photographic recording and anatomic evaluation are crucial to refined and comprehensive preoperative design and enhanced aesthetic effect of female genital cosmetic surgery. OBJECTIVES: The authors aim to propose a standard photographic scheme and physical examination form for the anatomical assessment of patients undergoing female genital surgery. METHODS: The scheme containing 2 positions (standing and lithotomy positions) and 11 views (1 frontal and 2 oblique views from standing position; 6 frontal views with labia minora open and closed, pulled to the opposite side, clitoral hood pushed up, posterior fourchette stretched; 2 oblique views from lithotomy position) (2P11V) is applied to record pre- and postoperative appearance of the vulva. The evaluation form is utilized to record characteristics of different anatomical subunits during photography. RESULTS: Two hundred forty-five patients who underwent female genital surgery were enrolled in the research from October 2018 to October 2022. All the patients received preoperative and postoperative 2P11V photography with about 5-minutes' shooting time. Various anatomical variations containing hypertrophy and prolapse of mons pubis, redundant types of labia minora and clitoral hood, incremental exposure of clitoral glans, hypo- to hypertrophy of labia majora, disappearance of interlabial groove, hypertrophy of posterior fourchette, and relation of subunits were accurately documented. CONCLUSIONS: 2P11V photographic scheme displays the isolated features of each organ and proportion relation among different parts of vulva. The standard photographic record and physical examination form offer detailed anatomical structure to surgeons and facilitate surgeons to carry out an accurate surgical design, which deserve to be promoted and applied.

Gender Affirming Graft Only Vaginoplasty.

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.

Abdominoplasty and Clitoris Evaluation: A Prospective Study on Sexual Pleasure in Women Undergoing Abdominoplasty.

INTRODUCTION: Being one of the most practiced procedures in plastic surgery, it is important to foster a better understanding of the effect of anatomical changes in the pubic area after abdominoplasty on sexuality in women. Since to date no study has been performed with this purpose, our aim is to evaluate the impact of the abdominoplasty on sexual pleasure and to perform an objective evaluation of changes in clitoral position and prepubic fat area after this procedure. MATERIALS AND METHODS: A prospective study has been performed in 50 women who expressed a desire to undergo abdominoplasty from January 2021 to December 2021. The primary endpoint was Sexual pleasure assessed by the "Sexuality Assessment Scale" before and 6 months after abdominoplasty in all patients. Furthermore, we evaluated the physical changes of the clitoris (clito-pubic distance, CP distance) and the prepubic fat area on magnetic resonance imaging before and 3 months after abdominoplasty. RESULTS: Patients mean age was of 42 ± 9 years, and mean body mass index of 26 ± 2 kg/m2. A significant difference (P < 0.0001) between sexual satisfaction before and 6 months after abdominoplasty (mean difference +7.4 ± 6.452) was found. Though there was no significant difference between the clito-pubic distance before and after abdominoplasty (mean difference -3.200 ± 2.499 mm; p= 0.0832), a significant difference was found in the size of the prepubic fat area before compared to after abdominoplasty (mean difference -1.714 ± 1.010 cm2; p = 0.0426). However, no significant relationship between these anatomical changes and sexual satisfaction was found. CONCLUSION: Our results show that abdominoplasty is associated with an increase in sexual satisfaction. The changes in the post-operative position of the clitoris were not statistically significant, contrarily to the size of the prepubic fat area, which was significantly modified and could partially explain the improved sexual pleasure. Authors were unable to statistically demonstrate a correlation between those anatomical modifications and sexual pleasure.

Hormone-dependent sexual responses of female mice in response to manual genital stimulation.

Although copulatory behavior is thought to have a strong innate basis in mice, there is also clear evidence that sexual experience shapes its expression. Reinforcement of behavior through rewarding genital tactile stimulation is a primary candidate mechanism for this modification. In rats, manual tactile clitoral stimulation is rewarding only when it is temporally distributed, which is hypothesized to result from an innate preference for species-typical copulatory patterning. Here we test this hypothesis using mice, which have a temporal copulatory pattern which is distinctly less temporally distributed than that of rats. Female mice received manual clitoral stimulation which was either temporally continuous every second, or stimulation which was temporally distributed, occurring every 5 s, This pattern of stimulation was paired with environmental cues in a conditioned place preference apparatus to assess reward. Neural activation in response to this stimulation was evaluated by measuring FOS immunoreactivity. Results indicated that both temporal patterns of clitoral stimulation were rewarding, but that continuous stimulation better reproduced brain activation associated with sexual reward. Furthermore, continuous, but not distributed stimulation elicited a lordosis response in some females, and this response increased within and across days. Sexual reward, neural activation and lordosis resulting from tactile genital stimulation were eliminated by ovariectomy and restored with combined 17ß-estradiol and progesterone treatment but not 17ß-estradiol treatment alone. These observations are consistent with the hypothesis that sexual reward resulting from species-typical genital tactile stimulation has a permissive effect on copulatory behavior of female mice.

How many nerve fibers innervate the human glans clitoris: a histomorphometric evaluation of the dorsal nerve of the clitoris.

INTRODUCTION: It is frequently quoted in mainstream media that the clitoris has "8000 nerve endings." However, no study has yet quantified the number of nerve fibers (axons) innervating the human clitoris. The dorsal nerves of the clitoris (DNCs) are the primary source of sensation and somatic clitoral innervation. Therefore, reporting the number of axons in the DNCs is an important step in our understanding of clitoral innervation and sexual response with implications for many fields of medical practice. The purpose of this study is to quantify the mean number of axons in the human DNCs and to report the approximate mean number of nerve fibers that innervate the human glans clitoris. METHODS: DNC samples were obtained from 7 transmasculine patients undergoing gender-affirming phalloplasty surgery. At the time of nerve coaptation, a small excess of the DNC (5 mm) was collected for analysis at the proximal level of the clitoral body, just distal of the emergence of the DNCs from underneath the pubic symphysis. Samples were placed into 3% glutaraldehyde fixative, postfixed in 1% osmium tetroxide, and serially dehydrated in ethanol and toluene. Samples were then embedded in araldite, sectioned on an ultramicrotome into 1-µm cross sections, and counterstained with 1% toluidine blue. Histomorphometric evaluation was performed at 1000x magnification with a Leitz Laborlux S microscope and image analysis software (Clemex Vision Professional) to obtain an axon counts. Descriptive statistics were performed to yield a mean and standard deviation of the number of axons in the DNCs. Assuming anatomic symmetry between bilateral DNCs, mean total number of somatic nerve fibers innervating the human glans clitoris was obtained by doubling the mean count of the DNCs. RESULTS: Seven sample DNCs were collected. Of those, 5 were analyzed as 2 did not have sufficient nerve tissue present. The mean number of nerve fibers in the human DNCs was 5140 (SD = 218.4). The mean number of myelinated nerve fibers innervating the human clitoris was 10,281 (SD = 436.8). CONCLUSION: This study is the first to report the number of axons in the human DNC, at a mean 5140. Given the bilateral nature of clitoral innervation and symmetry of anatomic structures, the approximate mean number of myelinated axons that innervate the human glans clitoris is 10,280. When the uncaptured unmyelinated fibers and contributions from the cavernosal innervation are accounted for, it is clear that far Moree than 8000 axons innervate the human clitoris.

Gendered genital modifications in critical anthropology: from discourses on FGM/C to new technologies in the sex/gender system.

Since the late 19th century, genital modifications (female and male) have been an important research subject in anthropology. According to a comparative and constructivist perspective, they were first interpreted as rites of passage, then as rites of institutions. In a complex dialogue with feminist movements, 20th-century scholars recognised that the cultural meanings of these modifications are multiple and changing in time and space. Conversely, according to WHO, since the 1950s, Female Genital Mutilation or Cutting (FGM/C) has been considered a form of Violence Against Women and Girls (VAWG). Interpreted as VAWG, FGM/C has progressively been isolated from its complementary male rite, selected for special condemnation, and banned. An order of discourse has been built by WHO and other international organisations. This article provides a genealogic deconstruction of the order of discourse lexicon, highlighting dislocations between anthropology and the human rights agenda. Today, genital modifications encompass FGM/C, male circumcision, clitoral reconstruction after FGM/C, gender reassignment surgery, and intersex and 'cosmetic' genital surgery. I propose to call these procedures Gendered Genital Modifications (GGMo). GGMo implicates public health, well-being, potential harm, sexuality, moral and social norms, gender empowerment, gender violence, and prohibitive and permissive policies and laws. The selective production of knowledge on FGM/C has reinforced the social and political polarisation between practices labelled as barbaric and others considered modern, accessible, and empowering. I suggest an anthropological interpretation for the socio-cultural meanings of health, sexuality, purity and beauty. I propose future interdisciplinary studies of how consent, bodily integrity and personal autonomy bear on concepts of agency and subjectivity in the sex/gender system.

Clitoral reconstruction: challenges and new directions.

Clitoral reconstruction (CR) has been the subject of several studies in recent years, mainly in the medical field. Women with female genital mutilation or cutting (FGM/C) seek clitoral reconstructive surgery to improve their sexual well-being, but also because they are affected by poor self- and body image. CR is supposed to help women with FGM/C reconstruct their sense of self, but the benefits and risks of this surgery have not been sufficiently explored. There are currently no recommendations supporting CR from mainstream medical bodies, and there have been very few ethical studies of the procedure. This article critically discusses the principal studies produced in the medical field and available reflections produced in the social sciences. Through the theoretical frameworks of postcolonial and feminist studies, the article discusses sexuality and pleasure, gender and identity, and race and positionality, with the aim of promoting collaborative work on CR between researchers and social and health professionals.

Sexual function analysis and clitoral vascularization in postmenopausal women with genitourinary syndrome treated with ospemifene.

BACKGROUND: The aim of this study was to evaluate the efficacy of ospemifene in the Vaginal Health Index (VHI), in the vulvovaginal vascular perfusion, and to assess its impact on quality of life and sexual function. METHODS: Among 52 eligible patients, 43 consecutive postmenopausal patients affected by vulvo-vaginal atrophy (VVA), or genitourinary syndrome (GSM) were evaluated. VVA evaluation and ultrasound of the vulvo-vaginal vascularization by sampling the Pulsatility Index (PI) of clitoris dorsal artery were performed before and after 3 months-treatment with ospemifene. The 36-Item Short Form Survey (SF-36) for the quality-of-life assessment before and after 3 months were available for all women; instead, Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires for the sexual function evaluation were performed for sexually active women in the study. The Patient Impression of Global Improvement (PGI-I) after 3 months of treatment was also calculated. RESULTS: The number of sexually active women significantly increased after 3 months (26 [60.46%] vs. 35 [81.39%]; P=0.01). The mean number of intercourses during the treatment increased (12.87±3.43 vs. 15.79±3.12, P=0.03). The PI of clitoris dorsal artery has significantly changed before and after treatment respectively (PI [1.69±0.42 vs. 1.28±0.45, P=0.001] RI [0.74±0.11 vs. 0.54±0.15, P=0.001]). The FSFI, FSDS and SF-36 Questionnaires scores showed a significant improvement after 3 months. VHI and PI were the independent factors of a lower FSFI after 3 months of treatment at multivariate analysis. CONCLUSIONS: Ospemifene improve the VHI and vulvovaginal vascular perfusion demonstrating a positive impact on sexual function and quality of life.

Why do parents recommend clitoral surgery? Parental perception of the necessity, benefit, and cost of early childhood clitoral surgery for congenital adrenal hyperplasia (CAH).

Historically, medical management of Congenital Adrenal Hyperplasia (CAH) in girls typically involved feminising surgery, which meant reducing the size and/or visibility of the enlarged clitoris. This practice may have become less routine but remains a common response to genital differences associated with CAH. Parents typically give permission for the child to undergo surgery in early childhood and recommend other parents facing a similar situation do the same. The current report is based on a qualitative content analysis of interviews with sixteen parents whose daughters with CAH had undergone one of two forms of clitoral surgery. We observed that: (i) some parents were initially unconcerned about their child's genital presentation; (ii) in general, clitoral surgery was considered as a readily available and natural response to the child's bodily difference; (iii) the parents acknowledged that there would be some risk but anticipated various benefits; and (iv) there was an absence of ethical considerations when the parents evaluated the various effects of surgery afterwards. We conclude from our analysis that parents of girls with CAH may not receive psychologically and ethically informed counselling to encourage critical reflections prior to authorizing genital surgery.
