Stereological comparison of smooth muscle, collagen, and elastic fibers of the clitoris and glans penis in young adults.

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.

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.

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.

Minimally Invasive Two-passage Electrical Genital Nerve Stimulation: A Human Cadaver Study of a New Technique.

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.

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.

Clitoral adhesions: a review of the literature.

INTRODUCTION: Clitoral adhesions occur when the prepuce adheres to the glans. These adhesions have been found in up to 22% of women seeking evaluation for sexual dysfunction. The etiology of clitoral adhesions remains largely unclear. Studies published to date on the presentation and management of clitoral adhesions are relatively recent and raise questions for future research. OBJECTIVES: We sought to provide a background of existing knowledge on the prevalence, presentation, etiology, associated conditions, and management of clitoral adhesions and to identify areas for future research. METHODS: A review of literature was performed for studies that investigate clitoral adhesions. RESULTS: Conditions associated with chronic clitoral scarring appear to have a role in the development of clitoral adhesions. Symptoms include clitoral pain (clitorodynia), discomfort, hypersensitivity, hyposensitivity, difficulty with arousal, and muted or absent orgasm. Complications include inflammation, infection, and the development of keratin pearls and smegmatic pseudocysts. There are surgical and nonsurgical interventions to manage clitoral adhesions. Additionally, topical agents can be included in conservative and/or postprocedural management. Although many studies on clitoral adhesions are limited to patients with lichen sclerosus (LS), clitoral adhesions are not confined to this population. CONCLUSION: Areas for future research include etiologies of clitoral adhesion; such knowledge is imperative to improve prevention and management. Also, in previous studies, patients were instructed to apply various topical agents and manually retract the prepuce for conservative management or postlysis care. However, the efficacy of these interventions has not been investigated. Surgical and nonsurgical lysis procedures have been described for the management of pain and difficulties with arousal and orgasm that are causes of the sexual dysfunction associated with clitoral adhesion. Although previous studies have assessed efficacy and patient satisfaction, many of these studies were limited to small sample sizes and focused solely on patients with LS. Future studies are needed to inform a standard of care for the management of clitoral adhesions.

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.

Anatomic relationships of the clitoral body, bulbs of the vestibule, and urethra.

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.
