RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

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

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.

RESUMO

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.

RESUMO

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.

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

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.

RESUMO

Despite some efforts to enhance clitoral knowledge to increase women's sexual pleasure, a gendered orgasm gap persists. We aimed to provide contemporary data on people's knowledge about the clitoris and investigate its association with the experience of sexual pleasure. Heterosexual participants (n = 573; 64.2% women) took a quiz on clitoral knowledge and answered sexuality-related questions. Participants answered only 50% of the nine quiz items correctly. Clitoral knowledge predicted sexual pleasure and orgasm in women, mediated via reduced endorsement of gendered sexual scripts. Our results highlight the importance of clitoral knowledge and its interplay with societal barriers for the experience of pleasure.

RESUMO

STUDY OBJECTIVE: To present and evaluate the feasibility of a new technique of lead-electrode stimulation to the genital nerves using a 2-step, double-passage retropubic/retrograde approach. DESIGN: Prospective observational study. INTERVENTIONS: The procedure was initiated in the retropubic passage by placing the electrode from below through a paravulvar/testicular small incision toward the urogenital diaphragm, guided through the retropubic space along the backside of the pubic bone. Through a second passage along the frontside of the pubic bone, the lead-electrode was placed finally at the genital nerves. SETTING: Department of Anatomy, University Bern, Bern, Switzerland PARTICIPANTS: The study was performed in 5 cadavers (bilaterally) and tested by 10 obstetrics and gynecology surgeons. MEASUREMENTS AND MAIN RESULTS: Positions and courses of the lead electrode in relation to the dorsal nerve of the clitoris/penis were evaluated by dissection of the genitals and showed an optimal parallel course of the lead electrodes to the dorsal nerve from the perforation of the urogenital diaphragm to the crura of the clitoris, with area of the dorsal nerve of the clitoris/penis to the electrode never exceeding 2 mm. Participant surgeons self-evaluated reproducibility and difficulty of the procedure by using a score from 1 to 10 (1, easy/safe; 10, extremely difficult/dangerous). Both reproducibility and difficulty achieved a score of 1 by all participants. CONCLUSIONS: The double-passage genital nerve stimulation procedure is a new peripheral nerve stimulation technique that had a high self-evaluated rate of ease and reproducibility for surgeon participants.

RESUMO

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.

RESUMO

The anatomy and physiology of the female orgasm are often neglected. The female orgasm is a normal psychophysiological function to all women, and some even can achieve ejaculation as part of the normal physiological response at the height of sexual arousal. The complexity of female sexuality requires a deep understanding of genital anatomy. The clitoris is the principal organ for female pleasure. The vaginal stimulation of the anterior vaginal wall led women to orgasm due to the stimulation of the clitourethrovaginal complex and not due to stimulation of a particular organ called the G spot in the anterior distal vaginal wall. Female ejaculation follows orgasm. It consists of the orgasmic expulsion of a smaller quantity of whitish fluid produced by the female prostate. Squirting can be differentiated from female ejaculation because it is the orgasmic transurethral expulsion of a substantial amount of diluted urine during sexual activity, and it is not considered pathological. The female orgasm is influenced by many aspects such as communication, emotional intimacy, long-standing relationship, adequate body image and self-esteem, proper touching and knowledge of the female body, regular masturbation, male sexual performance, male and female fertility, chronic pain, and capacity to engage in new sexual acts. Stronger orgasms could be achieved when clitoral stimulation, anterior vaginal wall stimulation, and oral sex is involved in the same sexual act.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Postoperative healing after clitoral reconstruction (CR) for female genital mutilation/cutting can be long and painful due to prolonged clitoral re-epithelialization time (up to 3 months). Autologous platelet-rich plasma (A-PRP) might reduce postoperative clitoral epithelialization time and pain. OBJECTIVES: The authors assessed postoperative clitoral re-epithelialization time and pain after intraoperative clitoral administration of A-PRP. METHODS: Five consecutive women underwent CR (Foldès technique) followed by the administration of A-PRP Regen Lab SA (Le Mont-sur-Lausanne, Switzerland) plasma and glue, injected inside and applied above the re-exposed clitoris, respectively. We recorded surgical complications, postoperative clitoral pain (visual analogue scale), painkiller intake, time to complete re-epithelialization, and the experienced subjective changes in sexual response and perception of their own body image referred by women. RESULTS: Sexual distress/dysfunction as well as the desire to be physically and symbolically "repaired" were the reasons behind women's requests for surgery. None of the women suffered from chronic vulvar or non-vulvar pain. All women achieved complete clitoral epithelialization by day 80, 3 women between day 54 and 70, and only 1 woman was still taking 1 g of paracetamol twice a day at 2 months postoperative. She had stopped it before the 3-month control. There were no short- or long-term complications. All women described easier access and stimulation of their clitoris as well as improved sexual arousal, lubrication, and pleasure and claimed to be satisfied with their restored body image. CONCLUSIONS: A-PRP could expedite postoperative clitoral epithelialization and reduce postoperative pain after CR after female genital mutilation/cutting.

RESUMO

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.

RESUMO

OBJECTIVE OF THE STUDY: The present work aims to observe the clitoris' extracellular matrix in young and old women with a scanning electron microscope. MATERIALS AND METHODS: After approval of the local research ethics committee, samples of the clitoris body were obtained from cadavers of women between 20 and 40 old (G1) and from cadavers over the age of 60 (G2). The samples were decellularized with NaOH to maintain the extracellular matrix framework, submitted to silver sputter coating, and observed under a scanning electron microscope. RESULTS: The mean age of the cadavers in G1 was 28 years old and 75±6 years old in G2. The groups were composed of 10 cadavers each. It was observed that the collagen was arranged in a disorganized fashion in the samples from the G2 in several regions. There was also a decrease in elastic fibers that anchored the collagen in these samples. The concentration of collagen showed an increase in the older samples in comparison to the G1 samples. Conclusions Female sexual dysfunction is a condition prevalent in a significantly large portion of women and it is more common in elderly women. It is known that the tumescence mechanism requires integrity of the extracellular matrix. The changes observed herein may alter the function of the organ and are similar to observations in studies of men with erectile dysfunction.
