RESUMO

This article analyses the conceptual histories of words associated with female genital parts to explore how they may affect the lived experience of people with these parts and the quality of gynaecological care they receive. Specifically, we examine the implications of using the word 'vagina' to replace the word 'vulva', or indeed to indicate the entire female genitalia. This article does so through an analysis of existing scholarly work and through text mining methods such as word frequencies, most distinctive word collocates and word-embeddings drawn from literary and women's magazine corpora. We find that words indicating specific female genital parts are very infrequently mentioned in our corpora, which shows that there is a troubling lack of exposure and education in our socio-cultural context when it comes to the female genital anatomy. When they are mentioned, their usage reflects historical and patriarchal associations that have been primarily attached to the word 'vagina'. When it comes to the 'vagina' and 'vulva', the penis is the most prevalent association by far; whereas the most commonly occurring female genital parts are parts to do with reproduction-reinforcing a long-standing and disproportionate emphasis on the female genitalia's reproductive function. Our research also reveals a concerning emphasis on non-evidence-based female hygiene products, thus perpetuating the damaging stereotype of the dirty vagina. These findings may explain many negative patient outcomes such as stigma attached to seeking out timely gynaecological care, lack of informed medical consent and non-evidence-based practices exacerbated by problematic cultural depictions of the female genitalia. They can also explain the neglect of female sexual agency, pleasure and well-being. Understanding historical and contemporary usages of words for the female genitalia has important implications for the quality of patient care today and is a critical component of gender and reproductive justice.

RESUMO

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.

RESUMO

BACKGROUND: The purpose of this study is to determine women's perceptions of the vulva with the criteria defined in the literature for the ideal vulva and determine their relationship with anatomical measurements to determine the extent to which women's perceptions of normal align with our aesthetic standards of normality. METHODS: First of all, a questionnaire was given to all participants. The items of the data collection form included personal information, obstetric and gynecological information, their perceptions of their external genitalia and any physical, sexual, psychological, and hygiene problems they experience. Then examination and measurements of the external genitalia were performed. RESULTS: The majority of participants considered their genitalia normal (n = 101, 89.4%), while 12 participants (10.6%) considered them abnormal. Statistical analyses showed that women's perception of their genitalia as normal in appearance and size was associated with labia minora asymmetry (p = 0.023 and p = 0.006, respectively) and hyperpigmentation (p = 0.010 and p = 0.047, respectively) but not with labia minora measurements or protrusion (p > 0.05). CONCLUSIONS: Although there is a tendency in the field of aesthetic surgery to define ideals and aesthetic standards for all parts of the body, our definitions of normality do not always coincide with those of the individual. The appearance of the genitalia is as personal as the face, and an individual's self-perception is more important than our ideal. LEVEL IV: Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.

RESUMO

BACKGROUND: Although recent studies have enhanced our understanding of the anatomy of the clitoris and its somatic innervation, less emphasis has been placed on the anatomic relationships of the clitoris to its surrounding structures. OBJECTIVE: This study aimed to further characterize the gross and histologic relationships of the clitoris, vestibular bulbs, and urethra. STUDY DESIGN: Detailed dissections were performed in 30 unembalmed female cadavers. In 23 specimens, gross dissections were performed, and relationships of the clitoris, vestibular bulbs, and urethra were annotated. Histologic evaluation was performed in 7 specimens, in which tissues were harvested within 24 hours from death. Descriptive statistics were used for data analyses. RESULTS: The clitoral body consisted of 2 components, the proximal body and the distal body. The distal body was oriented ≤90° from the proximal body, forming an outer and inner angle at the inflection point. A "septumlike" arrangement of fibroconnective and vascular tissues was noted between the inner angle of the clitoral body and the urethra. Neurovascular bundles coursed laterally along the clitoral body and the surfaces of the crura and vestibular bulbs. The vestibular bulbs approached each other over the ventral surface of the urethra, at the commissure of the vestibular bulbs. Each bulb was separated by fibrous tissue and did not merge along the midline. The vestibular bulbs approximated the clitoral body, but the erectile tissue of the vestibular bulbs was separated from the corpora cavernosa of the clitoral body by the tunica albuginea. The erectile tissue of the vestibular bulbs abutted the ventrolateral walls of the urethra but was separated from the urethral mucosa by an indiscrete layer of erectilelike tissue with dense stroma. CONCLUSION: This study provided gross and histological confirmation of the relationships of the clitoris, vestibular bulbs, and urethra. Detailed knowledge of the anatomy of the clitoris is crucial for reducing surgical complications associated with periclitoral and distal urethral procedures, which may adversely affect sexual arousal and sexual function.

RESUMO

Cosmetic labiaplasty is a form of Female Genital Cosmetic Surgery (FGCS) that is performed with the deliberate intent to alter the appearance and morphology of the external genitalia in the absence of medical concerns. Over the last decade, there is an increasing demand for FGCS and the industry behind it is constantly growing. Adolescents comprise an extremely vulnerable population, with labiaplasties in this particular age group having also increased. However, labiaplasty has been widely contested due to the irrevocable alteration of a psychosexually significant body part on minors too young to consent. Besides, the changes that occur during pubertal development in the genital area can significantly alter pediatric surgical results. Genital anatomy is more diverse than we previously thought and there is evidence to suggest that the labia minora with their rich innervation play an important role in sexual arousal and pleasure. Education regarding the wide range of normal genital appearance suffices in most cases to dissolve concerns regarding body self-image. Mental health issues should always be explored and, if identified, the girl should be referred to an experienced professional for their resolution. Postponing labiaplasty until adulthood is strongly recommended to help adolescents achieve a well-informed decision regarding an irreversible procedure with possible adverse esthetic and functional outcomes.

RESUMO

O'Connell et al. proposed that the vestibular bulbs be renamed the "clitoral bulbs" because of their consistent relationship to the clitoris and inconsistent relationship to the vestibule. Normally such proposed esoteric changes in anatomical nomenclature would get little notice by anatomists, yet alone the general public; however, many subsequent articles and books placed this change in the context of centuries of male anatomists and physicians downplaying female sexual anatomy and sexuality. Most prominent is a 2022 book by Rachel Gross, Vagina Obscura: An Anatomical Voyage. Here we review this "Anatomical Voyage" and find author bias in omitting/including erroneous facts in this book. We also present a critique of a 1995 article that appeared in Feminist Studies; Graphical Representations in Anatomy Texts, c1900-1991. This article, which has been repeatedly cited in the clinical literature, asserts that between circa 1950-1980 anatomy textbooks purposely eliminated depicting/labeling the clitoris in illustrations because the authors of the textbooks were reflecting societal norms that de-emphasized the importance of the clitoris. Unfortunately, the methods used by Moore and Clarke are not replicable; and further, their conclusions were not justified because of clear bias in their description and depiction of the anatomy sources they review.

RESUMO

What exactly is a vulva? The question remains unresolved. Some sources consider the clitoris, labia, mons pubis, perineum, or vagina to be components of the vulva, while other sources do not. Indeed, disagreement exists among international anatomical and clinical societies with regard to what precise structures form the human vulva. The obfuscation regarding the anatomy of the vulva and, likewise, inconsistencies in vulva-related anatomical terminology have adversely affected communication, research, and healthcare. Therefore, this review was undertaken to provide a comprehensive and critical analysis regarding the past, present, and potential future of vulvar anatomy and vulva-related anatomical terminology. The review reveals that confusion regarding the specific gross anatomical structures that form the vulva has persisted for thousands of years. The review provides novel information regarding the etymology of vulva, contributes important historical context regarding vulva, and gives details regarding related anatomical terminology including clitoris, hymen, labia majora, labia minora, mons pubis, pudendum, pudendum femininum/muliebre, uterus, vagina, et cetera. The review highlights disagreement regarding what specific structures comprise a vulva, identifies sexual bias in anatomical terminology and among noteworthy anatomical resources, and offers novel perspectives regarding anatomical terminology-especially anatomical terminology that relates to the external genitalia. What specific anatomical structures comprise the vulva? This review provides a comprehensive and critical analysis regarding the past, present, and potential future of vulvar anatomy and vulva-related anatomical terminology.

RESUMO

OBJECTIVE: To measure the anatomical dimensions of the vulva in adult Indian women. To analyze their correlations with age, body mass index (BMI), parity, and mode of delivery. METHODS: This cross-sectional study was conducted in a tertiary care university hospital in India, among 400 women aged 18 years and above. Various vulval measurements were taken, and Pearson's correction was applied to variables like age, BMI, parity, and mode of delivery. RESULTS: Mean length of glans of clitoris was 5.2 ± 1.43 mm, the labia minora width was 2.6 ± 0.74 cm, length of introitus was 1.3 ± 0.59 cm, and perineal body length was 2.3 ± 0.60 cm. The range of some measurements was extensive, for example labia minora width ranged from 0.7 to 4.9 cm. Normal centile curves were constructed for vulval measurements according to age groups. Statistically significant positive correlations of age, BMI, and obstetrical history were seen with labia minora width (r = 0.165, P = 0.001; r = 0.284, P < 0.001; r = 0.246, P < 0.001, respectively). CONCLUSION: The centile curves can be used as a reference for the Indian population of different ages. These can be used when counseling women coming for female genital cosmetic surgery.

RESUMO

BACKGROUND: Worldwide, 200 million girls and women have been subjected to female genital mutilation. To restore the clitoral function and vulvar anatomy, clitoral repair has been performed since the 2000s. Nevertheless, there is a lack of precise and comprehensive data on the clitoral anatomy during surgical repair. This study aimed to precisely describe the terminal anatomies of the dorsal nerve and artery of the clitoris, and the clitoral neurovascular flap advancement for reconstruction in patients with female genital mutilation. METHODS: This study was performed on seven fresh female cadavers. The site of origin, diameter, length, and trajectory of each nerve and artery were recorded. The clitoral neurovascular flap advancement was measured after a midline transection of the suspensory ligament was performed and after extensive liberation of the dorsal bundles at their emergence from the pubic rami. RESULTS: At the distal point of the clitoral body, the width of the dorsal nerve and artery was 1.9 ± 0.3 mm and 0.9 ± 0.2 mm, respectively. The total length of the dorsal bundles was 6.6 cm (± 0.4). The midpart of the suspensory ligament was sectioned, which allowed a mean anteroposterior mobility of 2.7 cm (± 0.2). Extensive dissection of the neurovascular bundles up to their point of emergence from the suspensory ligament allowed a mean mobility of 3.4 ± 0.2 cm. CONCLUSION: We described the anatomical characteristics of the dorsal nerve and artery of the clitoris and the mobility of the clitoral neurovascular flap for reconstruction post clitoridectomy. This was done to restore the anatomic position of the glans clitoris while preserving and potentially restoring clitoral function in patients with female genital mutilation.

RESUMO

Regional variation in pelvic morphology and childbirth has long occurred alongside traditional labour support and an understanding of possible normal courses of childbirth for each population. The process of migration and globalization has broken down these links, while a European model of 'normal' labour has become widespread. The description of 'normal' childbirth provided within obstetrics and midwifery textbooks, in fact, is modelled on a specific pelvic morphology that is common in European women. There is mounting evidence, however, that this model is not representative of women's diversity, especially for women of non-white ethnicities. The human birth canal is very variable in shape, both within and among human populations, and differences in pelvic shapes have been associated with differences in the mechanism of labour. Normalizing a white-centred model of female anatomy and of childbirth can disadvantage women of non-European ancestry. Because they are less likely to fit within this model, pelvic shape and labour pattern in non-white women are more likely to be considered 'abnormal', potentially leading to increased rates of labour intervention. To ensure that maternal care is inclusive and as safe as possible for all women, obstetric and midwifery training need to incorporate women's diversity. This article is part of the theme issue 'Multidisciplinary perspectives on social support and maternal-child health'.

RESUMO

BACKGROUND: Anatomic terminology in both written and verbal forms has been shown to be inaccurate and imprecise. OBJECTIVE: Here, we aimed to (1) review published anatomic terminology as it relates to the posterior female pelvis, posterior vagina, and vulva; (2) compare these terms to "Terminologia Anatomica," the internationally standardized terminology; and (3) compile standardized anatomic terms for improved communication and understanding. STUDY DESIGN: From inception of the study to April 6, 2018, MEDLINE database was used to search for 40 terms relevant to the posterior female pelvis and vulvar anatomy. Furthermore, 11 investigators reviewed identified abstracts and selected those reporting on posterior female pelvic and vulvar anatomy for full-text review. In addition, 11 textbook chapters were included in the study. Definitions of all pertinent anatomic terms were extracted for review. RESULTS: Overall, 486 anatomic terms were identified describing the vulva and posterior female pelvic anatomy, including the posterior vagina. "Terminologia Anatomica" has previously accepted 186 of these terms. Based on this literature review, we proposed the adoption of 11 new standardized anatomic terms, including 6 regional terms (anal sphincter complex, anorectum, genital-crural fold, interlabial sulcus, posterior vaginal compartment, and sacrospinous-coccygeus complex), 4 structural terms (greater vestibular duct, anal cushions, nerve to the levator ani, and labial fat pad), and 1 anatomic space (deep postanal space). In addition, the currently accepted term rectovaginal fascia or septum was identified as controversial and requires further research and definition before continued acceptance or rejection in medical communication. CONCLUSION: This study highlighted the variability in the anatomic nomenclature used in describing the posterior female pelvis and vulva. Therefore, we recommended the use of standardized terminology to improve communication and education across medical and anatomic disciplines.

RESUMO

OBJECTIVE: The aim of the study was to investigate the knowledge of vulvar anatomy and vulvar self-examination (VSE) in a sample of Italian women attending a gynecology clinic. METHODS: For this original research from May to July 2019, 512 women attending the Lower Genital Tract Clinic at the Department of Surgical Sciences of the University of Torino were invited to participate in a 29-question survey about vulvar anatomy, VSE, and sociodemographic details. Data were analyzed using descriptive statistics. RESULTS: Of 512 patients, 500 completed the questionnaire (98% response rate). The mean age of respondents was 41 years (range = 17-77 years). Education level was evenly distributed between elementary, high school, and university graduates. Only 15% of interviewed women were able correctly sketching vulvar anatomy. Seventy-six percent of the women had not heard about VSE, and 61% of the women approach their genitalia with feelings of shame and embarrassment. Only 23% of the women would seek medical advice after identification of possible abnormalities during VSE. A majority (69%) of the women would like to have more information about VSE and vulvar health through educational videos and social media. CONCLUSIONS: Education about VSE may lead to earlier diagnosis of vulvar cancers and other pathologies. Further efforts are needed to disperse information about normal external female genital anatomy and VSE to achieve self-confidence among women.

RESUMO

INTRODUCTION: Surgical and other procedures to alter the shape of the female external genitalia, especially the labia minora, are increasingly popular and controversial worldwide. OBJECTIVES: This article aims to delineate and complicate the medical and moral controversy around these vulvoplasty procedures, by describing how female genital aesthetics, their interpretation, and alteration vary over time, space, and culture. METHODS: The history of the Hottentot Venus is used as a pivot about which to consider current biomedical, anthropological, and ethical literatures regarding female genital appearance and its manipulation. Intersectionality describes how different systems influence each other to affect the agency of certain individuals or groups, and is therefore an ideal analytic method for biopsychosocial concerns of sex and informed consent. RESULTS: The 19th century anatomic study and display of Sarah "Saartjie" Baartman, the Hottentot Venus, defined a European vulvar ideal by demonstrating its opposite. Today, the ideal appearance of the labia minora is variable across cultures and nationalities, and various mechanical and surgical manipulations are sought or imposed upon women to bring their bodies into conformity with these ideals. CONCLUSION: For European audiences, Baartman exemplified a stereotypical association between genital appearance, sexual availability, and accessibility as a biomedical subject. These logical linkages were a by-product of sexist, racist, and colonial ideologies that have since fallen out of favor. However, their genital effects continue to influence bioethical considerations of genitoplasty into the present day. Chubak B. Historical and Ethical Perspectives on Vulvoplasty.

RESUMO

The conventional anatomical study of specimens requires cutting processes which destruct the limited specimens. A non-destructive method, namely an ultrasonography, can be used to assess the anatomical organ information of those specimens. The aim of this research is to analyse the macroanatomy of the female reproductive organ in the Sunda porcupine (Hystrix javanica), using ultrasonographical imaging. In this study, four formaldehyde-fixed reproductive organ specimens of the Sunda porcupine were used. A 10-12 MHz linear ultrasound transducer was utilized to provide an imaging format of both longitudinal and transversal views. Photographic images were then used as comparison with a sonographic image. The results show that the ultrasound image of the Sunda porcupine reproductive organ soft tissue was hypoechoic, the lumen and antrum follicles were anechoic, while atretic follicles and the mons pubis were hyperechoic. Generally, the size of the organ was not significantly different between photographical and ultrasonographical imaging (p > .05). In conclusion, ultrasound images can be utilized for anatomical studies of the Sunda porcupine reproductive organs without destructing the specimen.

RESUMO

It was hypothesized that Brahman cows have greater in vitro embryo production than Simmental cows, and that regardless of breed, antral follicle count (AFC) and vulvar width (VW) are positively associated with oocyte quality, embryo number and pregnancy rate. Brahman (Bos taurus indicus, n = 184) and Simmental (Bos taurus taurus, n = 99) cows were classified as having a large AFC (Brahman: ≥50, Simmental: ≥25); intermediate AFC (Brahman: >30 and ≤49; Simmental: >16 and <24) and small AFC (Brahman: <30, Simmental: ≤15). The VW was considered to be large (Brahman: >123 mm, Simmental: >80 mm); intermediate (Brahman: >102 mm and ≤123 mm; Simmental: >65 mm and ≤80 mm) and small (Brahman: ≤102 mm and Simmental: ≤65 mm). For each group of cows, ovum pick up, oocyte in vitro maturation, fertilization and embryo culture were performed. Embryo transfers were subsequently performed and pregnancy rate was evaluated. Brahman cows had a larger number of viable oocytes, greater efficiency of embryo production and greater pregnancy rate (P < 0.05) than Simmental cows. Pregnancy percentages in Simmental cows with a small AFC were greater than those cows with an intermediate and large AFC. With the Brahman cows, there was no difference in pregnancy rate among the cows with different AFC classifications. In contrast to Simmental cows, Brahman cows with an intermediate VW had a greater pregnancy percentage than those with a small and large AFC. In conclusion, Brahman cows have a larger AFC, number of viable oocytes, and pregnancy rate than Simmental cows.

RESUMO

Background In genital anomalies, measurement of total testosterone is required but is expensive and technically difficult to assay. Therefore, the measurement of anogenital distance, which is non-invasive and cheap, could be used to estimate total serum testosterone in neonates. The objective if this study is to determine the relationship between total serum testosterone and anogenital distance and estimate total serum testosterone levels in term neonates using measurements of anogenital distance. Methods This was a prospective cross-sectional study. Consecutive healthy term neonates were recruited in the first 72 h of postnatal life. Anogenital distance was measured with a digital vernier calliper. Total serum testosterone was determined using enzyme linked immunoassay. Results A total of 240 term neonates comprising 124 (51.7%) males and 116 (48.3%) females were studied. The overall mean anogenital distance was 19.7 (7.7) mm and 26.5 (3.7) mm for males which was more than twice 12.4 (2.3) mm for females (t = 35.3, p < 0.001, 95% confidence interval [CI], 13-14). The overall mean total serum testosterone level was 267.1 (204.8) ng/dL; and 357.4 (241.7) ng/dL in males which was more than twice of 170.6 (80.7) ng/dL for females (t = 7.9, p < 0.001, 95% CI, 144-221). There was positive correlation between total serum testosterone and anogenital distance (r = 0.425, p < 0.001). The correlation was stronger in males than in females. The linear regression equation was as follows: total serum testosterone (ng/dL) = 44.3 + 11.3*AGD (mm) with 95% CI, 8-14. Conclusions The known value of anogenital distance could be used to estimate total serum testosterone levels in term neonates.

RESUMO

BACKGROUND: Reproductive performance is critical for efficient swine production. Recent results indicated that vulva size (VS) may be predictive of reproductive performance in sows. Study objectives were to estimate genetic parameters, identify genomic regions associated, and estimate genomic prediction accuracies (GPA) for VS traits. RESULTS: Heritability estimates of VS traits, vulva area (VA), height (VH), and width (VW) measurements, were moderately to highly heritable in Yorkshire, with 0.46 ± 0.10, 0.55 ± 0.10, 0.31 ± 0.09, respectively, whereas these estimates were low to moderate in Landrace, with 0.16 ± 0.09, 0.24 ± 0.11, and 0.08 ± 0.06, respectively. Genetic correlations within VS traits were very high for both breeds, with the lowest of 0.67 ± 0.29 for VH and VW for Landrace. Genome-wide association studies (GWAS) for Landrace, reveled genomic region associated with VS traits on Sus scrofa chromosome (SSC) 2 (154-157 Mb), 7 (107-110 Mb), 8 (4-6 Mb), and 10 (8-19 Mb). For Yorkshire, genomic regions on SSC 1 (87-91 and 282-287 Mb) and 5 (67 Mb) were identified. All regions explained at least 3.4% of the genetic variance. Accuracies of genomic prediction were moderate in Landrace, ranging from 0.30 (VH) to 0.61 (VA), and lower for Yorkshire, with 0.07 (VW) to 0.11 (VH). Between-breed and multi-breed genomic prediction accuracies were low. CONCLUSIONS: Our findings suggest that VS traits are heritable in Landrace and Yorkshire gilts. Genomic analyses show that major QTL control these traits, and they differ between breed. Genomic information can be used to increase genetic gains for these traits in gilts. Additional research must be done to validate the GWAS and genomic prediction results reported in our study.

RESUMO

INTRODUCTION: Poor genital self-image is a common phenomenon leading to an increasing interest in female genital surgery over the last years. AIM: The aim was to correlate objective measurements of the labia minora with the individual subjective perception of the labial size. METHODS: In a cross-sectional study with 200 premenopausal women (median age 33.5 years) presenting for gynecological issues other than vulvar diseases, labial width and length were measured, and psychological and physical complaints were assessed. Multivariable logistic regression analyses were performed to identify factors that influenced self-reported complaints and subjective perception of labia size. MAIN OUTCOME MEASURE: The main outcome measure was labial appearance (width and length in mm, color), subjective perception of the labial size, and complaints. RESULTS: The median width of the labia minora was 19.0 mm (interquartile range = 12.6-27.5), and the median length was 35.5 mm (interquartile range = 27.8-48.9). The objective size of the labia was significantly associated with womens' subjective perception of the labial size, but not with self-reported complaints. Nearly one-third of the women (n = 53, 27%) reported complaints of their labia minora which were mainly physical (n = 41, 77%) or a combination of physical and psychological problems (n = 9, 17%), while only a small group reported experiencing only psychological complaints (n = 3, 6%). Predictors of complaints were previous cosmetic surgery and the subjective perception of the labia size. The latter was significantly associated with discomfort during intercourse and when visiting a sauna and by labia minora that protruded over the labia majora. CLINICAL IMPLICATIONS: Cutoff values to define labial hypertrophy and to justify labial reduction surgery should be avoided. STRENGTH & LIMITATIONS: This is a large sample of labial measurements in women not seeking labiaplasty. Standardized and validated questions regarding quality of life, sexuality, and body image could have provided more insight into psychological aspects. CONCLUSION: These data demonstrate the variability of labial anatomy and its perception. Widschwendter A, Riedl D, Freidhager K, et al.

RESUMO

Patients with vulvar dermatoses often delay seeking medical treatment because of anxiety and embarrassment. Moreover, women frequently self-treat with various home remedies and see multiple clinicians before presenting to a dermatologist. Despite serving as the primary providers for patients with vulvovaginal symptoms, gynecologists typically receive limited training in the causes and management of these conditions. Dermatologists are experts in the evaluation and management of cutaneous disease and should be the caretakers of all skin, including the genitalia. Vulvar disorders are underrecognized by dermatologists for numerous reasons: inadequate training, lack of comfort with both interview and examination techniques, and unfamiliarity with normal anatomic variations. The first article in this continuing medical education series on vulvar dermatoses reviews the fundamentals, approach, and techniques that can be used to ensure a successful visit for both patient and provider.
