Immunohistochemical staining with CD117 and PGP9.5 of excised vestibular tissue from patients with neuroproliferative vestibulodynia.

BACKGROUND: Neuroproliferative vestibulodynia (NPV), a provoked genital pain characterized by severe allodynia and hyperalgesia, is confirmed in excised vestibular tissue by immunohistochemical staining (>8 CD117-positive immunostained cells/100× microscopic field) rather than by hematoxylin and eosin staining. AIM: In this study we sought to assess immunostaining of tissue samples obtained during vestibulectomy surgery and to correlate results with patient outcomes. METHODS: Patients (n = 65) meeting criteria for NPV who underwent vestibulectomy during the period from June 2019 through December 2022 formed the study cohort. We performed assessment of pathology of vestibular tissues by use of immunohistochemical staining, including quantitation of mast cells by CD117 (mast cell marker) and nerve fibers by protein gene product (PGP) 9.5 (neuronal marker). We analyzed 725 photomicrographs of immunostained tissue sections (100× and 200×) by manual counting and computer-assisted histometry and correlated these data to clinical assessments. OUTCOMES: Outcomes included density of CD117 and PGP9.5 immunostaining in the 1:00-11:00 o'clock and 12:00 o'clock vestibular regions, and patient-reported outcomes assessing sexual function, pain, distress, and symptom improvement. RESULTS: All 65 NPV patients (median age 26 years), 45 with lifelong and 20 with acquired NPV, had severe pain documented by PROs and vulvoscopy and had >8 CD117-immunopositive cells/100× microscopic field. Median cell count values were similar in the 1:00-11:00 o'clock and 12:00 vestibular regions (28.5 and 29.5/100× field, respectively). Likewise, the marker) and nerve fibers by protein gene product (PGP) 9.5 (neuronal marker). We analyzed 725 photomicrographs of immunostained tissue sections (100× and 200×) by manual counting and computer-assisted histometry and correlated these data to clinical assessments. OUTCOMES: Outcomes included density of CD117 and PGP9.5 immunostaining in the 1:00-11:00 o'clock and 12:00 o'clock vestibular regions, and patient-reported outcomes assessing sexual function, pain, distress, and symptom improvement. RESULTS: All 65 NPV patients (median age 26 years), 45 with lifelong and 20 with acquired NPV, had severe pain documented by PROs and vulvoscopy and had >8 CD117-immunopositive cells/100× microscopic field. Median cell count values were similar in the 1:00-11:00 o'clock and 12:00 vestibular regions (28.5 and 29.5/100× field, respectively). Likewise, the median area of CD117 immunostaining was similar in both regions (0.69% and 0.73%). The median area of PGP9.5 immunostaining was 0.47% and 0.31% in these same regions. Pain scores determined with cotton-tipped swab testing were nominally higher in lifelong vs acquired NPV patients, reaching statistical significance in the 1:00-11:00 o'clock region (P < .001). The median score for the McGill Pain Questionnaire affective subscale dimension was also significantly higher in lifelong vs acquired NPV patients (P = .011). No correlations were observed between hematoxylin and eosin results and density of mast cells or neuronal markers. Of note, 63% of the patient cohort reported having additional conditions associated with aberrant mast cell activity. CLINICAL IMPLICATIONS: The pathology of NPV is primarily localized to the vestibular epithelial basement membrane and subepithelial stroma with no visible vulvoscopic findings, making clinical diagnosis challenging. STRENGTHS AND LIMITATIONS: Strengths of this study include the large number of tissues examined with what is to our knowledge the first-ever assessment of the 12:00 vestibule. Major limitations are specimens from a single timepoint within the disease state and lack of control tissues. CONCLUSIONS: Performing immunohistochemical staining of excised vestibular tissue with CD117 and PGP9.5 led to histometric confirmation of NPV, indications that NPV is a field disease involving all vestibular regions, validation for patients whose pain had been ignored and who had experienced negative psychosocial impact, and appreciation that such staining can advance knowledge.

Safety and efficacy of fractional CO2 laser treatment to the vestibule: a randomized, double-blind, sham-controlled, prospective 3-site clinical study in women with vestibular pain.

BACKGROUND: Data are limited regarding fractional CO2 laser as a nonhormonal treatment for vestibular pain. AIM: We sought to perform what is, to our knowledge, the first multisite prospective randomized, double-blind, sham-controlled clinical trial to assess the safety and efficacy of fractional CO2 laser treatment to the vestibule in women with vestibular pain. METHODS: Subjects (n = 70) meeting inclusion/exclusion criteria at each of 3 sites were randomized 2:1 to active or sham (zero energy) fractional CO2 laser treatment using the vestibular probe (SmartXide2 V2LR - MonaLisa Touch, DEKA, Florence, Italy). Subjects in each treatment arm received 3 treatments 4 weeks apart. At the initial follow-up (week 12), subjects were unblinded and those initially assigned to sham started active treatment. OUTCOMES: Outcome measures included changes from baseline in sexual activity diaries and scores for the Vulvoscopic Genital Tissue Appearance Scale (VGTA), vestibular cotton-tipped swab testing, McGill Pain Questionnaire, Female Sexual Function Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), and the O'Leary-Sant voiding and pain indices, the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI). RESULTS: After active treatment, VGTA scores significantly improved in 5 parameters. Pain associated with cotton-tipped swab testing was significantly reduced at weeks 4 through 16 (mean change from baseline -0.64 [95% CI, -0.79 to -0.50] and -1.31 [95% CI, -1.46 to -1.16], respectively). FSFI pain domain scores improved significantly at weeks 12 and 16 (mean change from baseline 0.925 [95% CI, 0.10-1.75] and 1.22 [95% CI, 0.40-2.05], respectively). FSFI total scores increased significantly at weeks 12 and 16 (mean change from baseline 6.24 [95% CI, 2.64-9.85] and 4.96 [95% CI, 1.36-8.57], respectively). FSDS-R scores decreased significantly at weeks 12 and 16 (mean change from baseline -5.84 [95% CI, -8.80 to -2.87] and -9.15 [95% CI, -12.11 to -6.18], respectively). ICSI scores decreased significantly at weeks 12 and 16 (mean change from baseline -0.91 [95% CI, -1.65 to -0.18] and -0.754 [95% CI, -1.49 to -0.02], respectively). ICPI scores decreased significantly at week 16 (mean change from baseline -0.99 [95% CI, -1.63 to -0.34]). In contrast, there were no significant changes in outcomes in the sham arm. No serious adverse events occurred. CLINICAL IMPLICATIONS: Fractional CO2 laser treatment in women with vestibular pain resulted in improvement from baseline in multiple key outcome measures of vestibular health. STRENGTHS AND LIMITATIONS: Strengths of the study were that it was a multisite prospective randomized double-blind, sham-controlled clinical trial that included multiple measures related to vestibular pain and sexual function. Limitations were the nonvalidated primary outcome measure and limited study cohort. CONCLUSION: Fractional CO2 laser therapy is a safe and effective nonhormonal treatment for vestibular pain.

Lumbar endoscopic spine surgery for persistent genital arousal disorder/genitopelvic dysesthesia resulting from lumbosacral annular tear-induced sacral radiculopathy.

BACKGROUND: Persistent genital arousal disorder/genitopelvic dysesthesia (PGAD/GPD) is characterized by distressing, abnormal genitopelvic sensations, especially unwanted arousal. In a subgroup of patients with PGAD/GPD, cauda equina Tarlov cyst-induced sacral radiculopathy has been reported to trigger the disorder. In our evaluation of lumbosacral magnetic resonance images in patients with PGAD/GPD and suspected sacral radiculopathy, some had no Tarlov cysts but showed lumbosacral disc annular tear pathology. AIM: The aims were 2-fold: (1) to utilize a novel multidisciplinary step-care management algorithm designed to identify a subgroup of patients with PGAD/GPD and lumbosacral annular tear-induced sacral radiculopathy who could benefit from lumbar endoscopic spine surgery (LESS) and (2) to evaluate long-term safety and efficacy of LESS. METHODS: Clinical data were collected on patients with PGAD/GPD who underwent LESS between 2016 and 2020 with at least 1-year follow-up. LESS was indicated because all had lumbosacral annular tear-induced sacral radiculopathy confirmed by our multidisciplinary management algorithm that included the following: step A, a detailed psychosocial and medical history; step B, noninvasive assessments for sacral radiculopathy; step C, targeted diagnostic transforaminal epidural spinal injections resulting in a temporary, clinically significant reduction of PGAD/GPD symptoms; and step D, surgical intervention with LESS and postoperative follow-up. OUTCOMES: Treatment outcome was based on the validated Patient Global Impression of Improvement, measured at postoperative intervals. RESULTS: Our cohort included 15 cisgendered women and 5 cisgendered men (mean ± SD age, 40.3 ± 16.8 years) with PGAD/GPD who fulfilled the criteria of lumbosacral annular tear-induced sacral radiculopathy based on our multidisciplinary management algorithm. Patients were followed for an average of 20 months (range, 12-37) post-LESS. Lumbosacral annular tear pathology was identified at multiple levels, the most common being L4-L5 and L5-S1. Twenty-two LESS procedures were performed in 20 patients. Overall, 80% (16/20) reported improvement on the Patient Global Impression of Improvement; 65% (13/20) reported improvement as much better or very much better. All patients were discharged the same day. There were no surgical complications. CLINICAL IMPLICATIONS: Among the many recognized triggers for PGAD/GPD, this subgroup exhibited lumbosacral annular tear-induced sacral radiculopathy and experienced long-term alleviation of symptoms by LESS. STRENGTHS AND LIMITATIONS: Strengths include long-term post-surgical follow-up and demonstration that LESS effectively treats patients with PGAD/GPD who have lumbosacral annular tear-induced sacral radiculopathy, as established by a multidisciplinary step-care management algorithm. Limitations include the small study cohort and the unavailability of a clinical measure specific for PGAD/GPD. CONCLUSION: LESS is safe and effective in treating patients with PGAD/GPD who are diagnosed with lumbosacral annular tear-induced sacral radiculopathy.

The prostate in women: an updated histological and immunohistochemical profile of the female periurethral glands and their relationship to an implanted midurethral sling.

BACKGROUND: There is evidence of glandular tissue in the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) that has similar morphology and immunohistochemistry to the prostate in men. Surgical injury to this tissue has been suggested as a potential cause of sexual dysfunction following midurethral sling (MUS) procedures. However, the anatomy and embryology of these glands have not been fully resolved. This has led to difficulties in classifying this tissue as a prostate and defining its clinical significance related to MUS procedures. AIM: To describe the histological and immunohistochemical characteristics of the female periurethral glands using markers of prostate tissue and innervation and to examine their anatomical relationships to an implanted MUS. METHODS: Using gross and fine dissection, the AVW-FPT was dissected from 9 cadavers. Prior to dissection, 2 cadavers underwent simulation of the MUS procedure by a urogynecologist. Samples were paraffin embedded and serially sectioned. Immunohistochemistry was performed using markers of prostate tissue and innervation. OUTCOMES: Immunohistochemical localization of markers for prostatic tissue and innervation of the glandular tissue of the AVW-FPT, including the region of MUS implantation. RESULTS: Female periurethral glands were immunoreactive for markers of male prostatic tissue, including prostate-specific antigen, androgen receptor, HOXB13, and NKX3.1. Markers of innervation (protein gene product 9.5, choline acetyl transferase, and vasoactive intestinal polypeptide) also localized to certain regions of the glandular tissue and associated blood supply. Surgical simulation of the MUS procedure demonstrated that some periurethral glands are located in close proximity to an implanted sling. CLINICAL TRANSLATION: The AVW-FPT contains glandular tissue in the surgical field of MUS implantation. Iatrogenic damage to the female periurethral glands and the associated innervation during surgery could explain the negative impacts on sexual dysfunction reported following MUS procedures. STRENGTHS AND LIMITATIONS: This is the first study to characterize the female periurethral glands using markers of prostatic tissue in concert with markers of general and autonomic innervation and characterize their anatomical relationships within the surgical field of MUS implantation. The small sample size is a limitation of this study. CONCLUSION: We provide further evidence that the AVW-FPT contains innervated glands that are phenotypically similar to the male prostate and may share a common embryonic origin. The microscopic and immunohistochemical features of the periurethral glands may be indicative of their functional capacity in sexual responses. The location of these glands in the surgical field of MUS procedures underscores the clinical significance of this tissue.

Patient and provider perspectives on LEEP/LLETZ treatment and outcomes: an interview study.

BACKGROUND: The loop electrosurgical excision procedure (LEEP) and large loop excision of the transformation zone (LLETZ) effectively treat cervical dysplasia, though some women have reported negative outcomes postoperatively (e.g., sexual dysfunction, psychosexual sequalae). There is insufficient understanding of patient experiences with these symptoms and perspectives from the providers who perform LEEP/LLETZ. AIM: To characterize the perceptions and experiences of LEEP/LLETZ treatment from providers and patients, including whether there is a characteristic symptom profile of women who report negative outcomes. METHODS: Patients who had LEEP/LLETZ treatment and reported negative outcomes and providers who perform LEEP/LLETZ completed semistructured interviews about their perceptions and experiences, which were coded through thematic analysis (NVivo 12; QSR International). Patients also completed an online survey assessing demographics, medical history, and sexual function. OUTCOMES: Outcomes included perspectives generated from patient and provider interviews regarding LEEP/LLETZ procedural outcomes, including symptoms and experiences related to sexual functioning. RESULTS: Perspectives and experiences gathered from patient and provider interviews revealed misaligned narratives surrounding LEEP/LLETZ outcomes and treatment. We identified 4 overarching themes encapsulating provider and patient responses: Expectations for Preoperative Consultation; Procedure Experiences; Attitudes; and Resources. Patients reported a unique symptom profile and negative outcome experiences, namely surrounding domains of sexual functioning: decreased physical sensations, orgasm response, and vaginal discharge, as well as loss of arousal, interest, and desire. Patients described changes to overall quality of life, with impacts to interpersonal relationships. Patients discussed preferring open-ended and directed questions to comprehensively elucidate negative outcomes. Provider narratives outlined the current process of care, emphasizing limited experiences with adverse outcomes (e.g., sexual issues) and the use of open-ended questions during counseling. Providers described an evolving intention to create comfortable clinical spaces. Regarding pre- and postoperative resources, patients described seeking support from online patient groups, and providers disclosed limitations to providing resources. CLINICAL IMPLICATIONS: Evidence of discordance between patient and provider perspectives of LEEP/LLETZ reveals a need to reassess clinical practices surrounding this procedure at the level of discussions regarding informed consent, sexual function, and available resources. STRENGTHS AND LIMITATIONS: This study is the first to examine patient and provider perspectives on LEEP/LLETZ treatment. Only patients who self-report negative outcomes were recruited, to elicit narratives from this specific subpopulation. CONCLUSION: Results indicate a characteristic symptom profile of women who undergo LEEP/LLETZ and report negative outcomes and that the perceptions of patients and providers differ regarding several aspects of the treatment experience, supporting the need for directed open conversation and comprehensive pre- and postoperative sexual counseling.

The contribution of the cervix to sexual response: an online survey study.

BACKGROUND: The role of the cervix in sexual response has been poorly studied, despite previous research indicating that some women experience pleasurable sexual sensations from cervical stimulation; given previous reports of sexual issues after cervix electrocautery, it is possible that cervical injury may compromise the role of the cervix in sexual functioning. AIM: The aims of this study were to examine locations of pleasurable sexual sensations, to identify sexual communication barriers, and to investigate if cervical procedures are associated with negative impacts on sexual function. METHODS: Women with (n = 72) and without (n = 235) a history of a gynecological procedure completed an online survey assessing demographics, medical history, sexual function (including locations of sexual pleasure and pain on diagrams), and barriers. The procedure group was divided into subgroups of those who had experienced a cervical (n = 47) or noncervical (n = 25) procedure. Chi-square analyses and t tests were conducted. OUTCOMES: Outcomes included locations and ratings of pleasurable and painful sexual stimulation, as well as sexual function. RESULTS: Over 16% of participants reported experiencing some pleasurable sexual sensations from the cervix. The gynecological procedure group (n = 72) reported significantly higher pain in the vagina and lower rates of pleasure in their external genitals, vagina, deep vagina, anterior and posterior vaginal walls, and clitoris vs the non-gynecological procedure (n = 235) group. The gynecological procedure group and the cervical procedure subgroup (n = 47) reported significant decreases in desire, arousal, and lubrication and increased avoidance of sexual activity due to vaginal dryness. The gynecological procedure group reported significant pain with vaginal stimulation, whereas the cervical subgroup identified significant pain with cervical and clitoral stimulation. CLINICAL IMPLICATIONS: Cervical stimulation elicits some pleasurable sexual sensations for many women, and gynecological procedures that affect the cervix are associated with pain and sexual issues; thus, health care providers should counsel patients about the possibility of related sexual concerns. STRENGTHS AND LIMITATIONS: This study is the first to examine locations of pleasure and pain and experiences of sexual pleasure and function in participants who underwent a gynecological procedure. A hybrid measure was used to assess sexual issues, including symptoms of dysfunction. CONCLUSION: Results indicate an association between cervical procedures and sexual issues, supporting the need to inform patients of this possibility following cervical procedures.

Characterizing the innervation of the vulvar vestibule and the immunohistochemical features of neuroproliferative vestibulodynia.

BACKGROUND: Provoked vestibulodynia (PVD) is a chronic pain condition characterized by allodynia localized to the vulvar vestibule. The finding of increased densities of nerve fibers in the vestibular mucosa of patients with PVD has led to the identification of a neuroproliferative subtype. The etiology of PVD, including neuroproliferative vestibulodynia (NPV), is not fully understood. The gross and microscopic innervation of the vulvar vestibule remains incompletely described, despite the preliminary data supporting the role of peripheral innervation in PVD. AIM: To characterize the gross anatomic and microscopic innervation of the vulvar vestibule through cadaveric dissection and immunohistochemistry. METHODS: The pudendal nerve and inferior hypogastric plexus (IHP) were dissected using 6 cadaveric donors. Histology and immunohistochemistry were used to confirm patterns of innervation identified gross anatomically. Immunohistochemistry was performed on vestibulectomy specimens obtained from 6 patients diagnosed with NPV and compared with cadaveric vestibular tissues. OUTCOMES: Outcomes included (1) dissection of pelvic innervation and (2) immunohistochemical localization of markers for the following: general innervation protein gene product 9.5 (PGP9.5), sensory innervation (calcitonin gene-related peptide), autonomic innervation (vasoactive intestinal polypeptide, tyrosine hydroxylase), neuroproliferation (nerve growth factor [NGF]), and immune activation (C-kit). RESULTS: Perineal (pudendal) nerve branches were traced to the external wall of the vulvar vestibule. Some anatomic heterogeneity was observed in perineal nerve-branching patterns. Fibers from the IHP were identified in close proximity to the vulvar vestibule. Autonomic and sensory nerve fibers were identified in both patient and cadaveric vulvar vestibule samples. Patient samples were characterized by the proliferation of PGP9.5-positive nerve fibers and C-kit-positive mast cells, which were in proximity to neve bundles and showed coexpression with putative NGF-positive cells. NGF expression was localized to a subset of nerves, including those that demonstrated co-expression of sensory and autonomic nerve markers. Increased densities of autonomic fibers positive for vasoactive intestinal polypeptide and tyrosine hydroxylase were observed in 1 patient sample. CLINICAL TRANSLATION: Heterogeneity in gross and microscopic patterns of innervation could explain variability in clinical response to treatment and should be used to inform future therapeutic interventions. STRENGTHS AND LIMITATIONS: This study used a combination of approaches to elucidate the innervation of the vulvar vestibule, including in NPV. The small sample size is a limitation. CONCLUSION: The vulvar vestibule contains both sensory and autonomic innervation, which may originate from the pudendal nerve and IHP. Our results support the existence of a neuroproliferative subtype that is characterized by the proliferation of sensory and autonomic nerve fibers and neuroimmune interactions.

Immunohistochemical Investigation of Autonomic and Sensory Innervation of Anterior Vaginal Wall Female Periurethral Tissue: A Study of the Surgical Field of Mid-Urethral Sling Surgery Using Cadaveric Simulation.

BACKGROUND: Female sexual dysfunction, including female orgasm disorder, has been reported following mid-urethral sling (MUS) surgery to treat bothersome stress urinary incontinence. Anterior vaginal wall-female periurethral tissue (AVW-FPT) likely contains autonomic and sensory innervation involved in the female sexual response, and injury to these nerves may result from MUS implantation. AIM: To characterize, using fresh cadaveric tissue, autonomic and sensory nerves in AVW- FPT using immunohistochemistry (IHC), and to assess their proximity to an implanted MUS. METHODS: AVW-FPT was excised following careful dissection from four fresh cadavers. Prior to dissection, one cadaver underwent simulation of the MUS procedure by a urogynegologist, using a fascial sling. All samples were paraffin embedded, sectioned, and stained with hematoxylin. Serial sectioning and IHC were performed to identify nerves. IHC markers were used to characterize the sensory and autonomic innervation. OUTCOMES: IHC localization of autonomic and sensory nerve markers consistent with neural tissue within the region of MUS implantation. RESULTS: IHC of AVW-FPT using protein gene product 9.5 (PGP9.5), a general nerve stain, revealed innervation throughout the region targeted by the MUS implantation. More specifically, immunoreactivity for both autonomic (tyrosine hydroxylase, TH) and sensory (Nav1.8 and S100ß) nerves were found in close proximity (<1 mm) to the implanted MUS. In addition, a subset of S100ß positive nerves also showed immunoreactivity for calcitonin gene-related peptide (CGRP). Combining the IHC findings with the surgical simulation of the MUS implantation revealed the potential for damage to both autonomic and sensory nerves as a direct result of the MUS procedure. CLINICAL TRANSLATION: The identified autonomic and sensory nerves of the AVW-FPT may contribute to the female sexual response, and yet are potentially negatively impacted by MUS procedures. Given that surgeries performed on male genital tissue, including the prostate, may cause sexual dysfunction secondary to nerve damage, and that urologists routinely provide informed consent regarding this possibility, urogynaecologists are encouraged to obtain appropriate informed consent from prospective patients undergoing the MUS procedure. STRENGTHS & LIMITATIONS: This is the first study to characterize the sensory and autonomic innervation within the surgical field of MUS implantation and demonstrate its relationship to an implanted MUS. The small sample size is a limitation of this study. CONCLUSION: The present study provides evidence of potential injury to autonomic and sensory innervation of AVW-FPT as a consequence of MUS implantation, which may help explain the underlying mechanisms involved in the reported post-operative female sexual dysfunction in some women.

International Society for the Study of Women's Sexual Health Clinical Practice Guideline for the Use of Systemic Testosterone for Hypoactive Sexual Desire Disorder in Women.

BACKGROUND: The Global Consensus Position Statement on the Use of Testosterone Therapy for Women (Global Position Statement) recommended testosterone therapy for postmenopausal women with hypoactive sexual desire disorder (HSDD). AIM: To provide a clinical practice guideline for the use of testosterone including identification of patients, laboratory testing, dosing, post-treatment monitoring, and follow-up care in women with HSDD. METHODS: The International Society for the Study of Women's Sexual Health appointed a multidisciplinary panel of experts who performed a literature review of original research, meta-analyses, review papers, and consensus guidelines regarding testosterone use in women. Consensus was reached using a modified Delphi method. OUTCOMES: A clinically useful guideline following a biopsychosocial assessment and treatment approach for the safe and efficacious use of testosterone in women with HSDD was developed including measurement, indications, formulations, prescribing, dosing, monitoring, and follow-up. RESULTS: Although the Global Position Statement endorses testosterone therapy for only postmenopausal women, limited data also support the use in late reproductive age premenopausal women, consistent with the International Society for the Study of Women's Sexual Health Process of Care for the Management of HSDD. Systemic transdermal testosterone is recommended for women with HSDD not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. Current available research supports a moderate therapeutic benefit. Safety data show no serious adverse events with physiologic testosterone use, but long-term safety has not been established. Before initiation of therapy, clinicians should provide an informed consent. Shared decision-making involves a comprehensive discussion of off-label use, as well as benefits and risks. A total testosterone level should not be used to diagnose HSDD, but as a baseline for monitoring. Government-approved transdermal male formulations can be used cautiously with dosing appropriate for women. Patients should be assessed for signs of androgen excess and total testosterone levels monitored to maintain concentrations in the physiologic premenopausal range. Compounded products cannot be recommended because of the lack of efficacy and safety data. CLINICAL IMPLICATIONS: This clinical practice guideline provides standards for safely prescribing testosterone to women with HSDD, including identification of appropriate patients, dosing, and monitoring. STRENGTHS & LIMITATIONS: This evidence-based guideline builds on a recently published comprehensive meta-analysis and the Global Position Statement endorsed by numerous societies. The limitation is that testosterone therapy is not approved for women by most regulatory agencies, thereby making prescribing and proper dosing challenging. CONCLUSION: Despite substantial evidence regarding safety, efficacy, and clinical use, access to testosterone therapy for the treatment of HSDD in women remains a significant unmet need.

International Society for the Study of Women's Sexual Health (ISSWSH) Review of Epidemiology and Pathophysiology, and a Consensus Nomenclature and Process of Care for the Management of Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD).

BACKGROUND: Persistent genital arousal disorder (PGAD), a condition of unwanted, unremitting sensations of genital arousal, is associated with a significant, negative psychosocial impact that may include emotional lability, catastrophization, and suicidal ideation. Despite being first reported in 2001, PGAD remains poorly understood. AIM: To characterize this complex condition more accurately, review the epidemiology and pathophysiology, and provide new nomenclature and guidance for evidence-based management. METHODS: A panel of experts reviewed pertinent literature, discussed research and clinical experience, and used a modified Delphi method to reach consensus concerning nomenclature, etiology, and associated factors. Levels of evidence and grades of recommendation were assigned for diagnosis and treatment. OUTCOMES: The nomenclature of PGAD was broadened to include genito-pelvic dysesthesia (GPD), and a new biopsychosocial diagnostic and treatment algorithm for PGAD/GPD was developed. RESULTS: The panel recognized that the term PGAD does not fully characterize the constellation of GPD symptoms experienced by patients. Therefore, the more inclusive term PGAD/GPD was adopted, which maintains the primacy of the distressing arousal symptoms and acknowledges associated bothersome GPD. While there are diverse biopsychosocial contributors, there is a common underlying neurologic basis attributable to spontaneous intense activity of the genito-pelvic region represented in the somatosensory cortex and its projections. A process of care diagnostic and treatment strategy was developed to guide the clinician, whenever possible, by localizing the symptoms as originating in any of five regions: (i) end organ, (ii) pelvis/perineum, (iii) cauda equina, (iv) spinal cord, and (v) brain. Psychological treatment strategies were considered critical and should be performed in conjunction with medical strategies. Pharmaceutical interventions may be used based on their site and mechanism of action to reduce patients' symptoms and the associated bother and distress. CLINICAL IMPLICATIONS: The process of care for PGAD/GPD uses a personalized, biopsychosocial approach for diagnosis and treatment. STRENGTHS AND LIMITATIONS: Strengths and Limitations: Strengths include characterization of the condition by consensus, analysis, and recommendation of a new nomenclature and a rational basis for diagnosis and treatment. Future investigations into etiology and treatment outcomes are recommended. The main limitations are the dearth of knowledge concerning this condition and that the current literature consists primarily of case reports and expert opinion. CONCLUSION: We provide, for the first time, an expert consensus review of the epidemiology and pathophysiology and the development of a new nomenclature and rational algorithm for management of this extremely distressing sexual health condition that may be more prevalent than previously recognized.

Toward a More Evidence-Based Nosology and Nomenclature for Female Sexual Dysfunctions-Part III.

INTRODUCTION: In 2016 the International Society for the Study of Women's Sexual Health (ISSWSH) published an expert consensus report on new nomenclature that addressed the need for comprehensive, evidence-based criteria for new diagnoses in desire, arousal, and orgasm, with the definition on arousal focusing exclusively on female genital arousal disorder (FGAD). AIM: A new expert panel solely focused on mechanisms of arousal disorders convened to revise the nomenclature to include female cognitive arousal disorder (FCAD) and FGAD. METHODS: The ISSWSH co-chairs identified experts on arousal disorders in women. The 10 participants included clinicians, researchers, and educators, representing a diverse, multidisciplinary group. Pre-meeting preparation included evidence-based literature review as the basis of presentations panelists made at the meeting on the current knowledge in cognitive arousal. Consensus was reached using a modified Delphi method. Writing assignments were made as a basis of manuscript development. MAIN OUTCOME MEASURES: The new definition of FCAD is characterized by distressing difficulty or inability to attain or maintain adequate mental excitement associated with sexual activity, as manifested by problems with feeling engaged and mentally turned on or sexually aroused for a minimum of 6 months. RESULTS: Female sexual arousal disorder encompasses both FGAD (revised definition) and FCAD (new definition). Recommendations regarding diagnosis include a clinical interview to assess for FCAD using targeted questions. Patient-reported outcomes that contain questions to assess FCAD are described, including limitations for differentiating between cognitive arousal, genital arousal, and sexual desire. Laboratory measures of cognitive and genital arousal are discussed, including the relationships between genital and cognitive arousal patterns. Biopsychosocial risk factors for FCAD and FGAD, as well as exclusionary conditions, are presented. CLINICAL IMPLICATIONS: The revision of the ISSWSH nomenclature regarding the criteria for the 2 arousal categories, FCAD and FGAD, and the recommended diagnostic strategies offers a framework for management of women with arousal disorders. STRENGTHS & LIMITATIONS: This nomenclature allows for basic science and clinical research in subtypes of arousal in order to develop better diagnostic and treatment options for use by clinicians, scientists, and regulatory agencies. There are limited validated measures of cognitive arousal, including the Female Sexual Function Index, the most commonly used measure, which does not effectively distinguish between cognitive excitement, genital sensations, and event-related desire. CONCLUSION: Future directions include the refinement of FCAD and FGAD and development and validation of patient-reported outcomes that distinguish between the cognitive processes and genital responses to enhance clinical care and research in this area.

Existing and Future Educational Needs in Graduate and Postgraduate Education.

INTRODUCTION: This review was designed to make recommendations on future educational needs, principles of curricular development, and how the International Society for Sexual Medicine (ISSM) should address the need to enhance and promote human sexuality education around the world. AIM: To explore the ways in which graduate and postgraduate medical education in human sexuality has evolved and is currently delivered. METHODS: We reviewed existing literature concerning sexuality education, curriculum development, learning strategies, educational formats, evaluation of programs, evaluation of students, and faculty development. We reviewed literature relating to four main areas: (i) the current status of the international regulation of training in sexual medicine; (ii) the current delivery of education and training in sexual medicine; (iii) resident and postgraduate education in sexual medicine surgery; and (iv) education and training for allied health professionals. RESULTS: The main findings in these four areas are as follows. Sexual medicine has grown considerably as a specialty during the past 20 years, with many drivers being identified. However, the regulatory aspects of training, assessment, and certification are currently in the early stages of development and are in many ways lagging behind the scientific and clinical knowledge in the field. However, there are examples of the development of curricula with accompanying assessments that have attempted to set standards of education and training that might underlie the delivery of high-quality care to patients in sexual medicine. The development of competence assessment has been applied to surgical training in sexual medicine, and there is increasing interest in simulation as a means of enhancing technical skills training. Although the focus of curriculum development has largely been the medical profession, there is early interest in the development of standards for training and education of allied health professionals. CONCLUSION: Organizations of professionals in sexual health, such as the ISSM, have an opportunity, and indeed a responsibility, to provide and disseminate learning opportunities, curricula, and standards of training for doctors and allied health professionals in sexual medicine.

Toward a More Evidence-Based Nosology and Nomenclature for Female Sexual Dysfunctions-Part II.

INTRODUCTION: Current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) definitions of sexual dysfunction do not identify all sexual problems experienced clinically by women and are not necessarily applicable for biologic or biopsychosocial management of female sexual dysfunction. A unified nomenclature system enables clinicians, researchers, and regulatory agencies to use the same language and criteria for determining clinical end points, assessing research results, and managing patients. AIM: To develop nomenclature with classification systems for female sexual desire, arousal, and orgasm disorders with definitions pertinent to clinicians and researchers from multiple specialties who contribute to the field of sexual medicine. METHODS: Key national and international opinion leaders diverse in gender, geography, and areas of expertise met for 2 days to discuss and agree to definitions of female sexual desire, arousal, and orgasm disorders and persistent genital arousal disorder. The attendees consisted of 10 psychiatrists and psychologists; 12 health care providers in specialties such as gynecology, internal medicine, and sexual medicine; three basic scientists; and one sexuality educator, representing an array of societies working within the various areas of sexual function and dysfunction. MAIN OUTCOME MEASURE: A unified set of definitions was developed and accepted for use by the International Society for the Study of Women's Sexual Health (ISSWSH) and members of other stakeholder societies participating in the consensus meeting. RESULTS: Current DSM-5 definitions, in particular elimination of desire and arousal disorders as separate diagnoses and lack of definitions of other specific disorders, were adapted to create ISSWSH consensus nomenclature for distressing sexual dysfunctions. The ISSWSH definitions include hypoactive sexual desire disorder, female genital arousal disorder, persistent genital arousal disorder, female orgasmic disorder, pleasure dissociative orgasm disorder, and female orgasmic illness syndrome. CONCLUSION: Definitions for female sexual dysfunctions that reflect current science provide useful nomenclature for current and future management of women with sexual disorders and development of new therapies.

Correlation of question 15 of the FSDS-DAO with clinician evaluation of female orgasmic disorder.

INTRODUCTION: Female orgasmic disorder (FOD) is the second most frequently reported sexual dysfunction in women. According to the Diagnostic and Statistical Manual of Mental Disorders, the term "marked distress" is central to the diagnosis of FOD. AIM: Objectives of this study were to explore terminology used by women diagnosed with FOD to describe their associated feelings and establish a correlation between patient ratings of question 15, "How often do you feel frustrated by problems with orgasm" on the Female Sexual Distress Score/Desire Arousal Orgasm (FSDS-DAO) with clinician evaluations of FOD. METHODS: Research was performed at one sexual medicine facility. Recruited participants were patients diagnosed with FOD. Fifteen women meeting inclusion/exclusion criteria were enrolled, completed the FSDS-DAO and a structured interview to assess terminology associated with orgasm difficulties. MAIN OUTCOME MEASURE: Patient reported terminology for characterization of FOD, validity of question 15 of FSDS-DAO. RESULTS: When asked to describe their orgasm difficulties, 60% of participants said "frustrated." Other terms included disappointed, pariah, subhuman, desperate, and concerned. Fifty-three percent (53%) claimed their inability to orgasm affected day-to-day life. In participants where FOD did not affect day-to-day life, 57% actively suppressed thoughts about inability to orgasm. Responses to question 15 of the FSDS-DAO ranged from 2-4 (mean 3.6) indicating participants were very frustrated. CONCLUSIONS: To diagnose FOD, clinicians assess the level of associated distress through individualized patient interviews with no standardized tool. The term "distressed" is a medical construct and did not resonate with participants when describing their experience. participants used "frustrated" as an emotional descriptor to their sexual experience and scored high on question 15 of the FSDS-DAO. This study demonstrates the FSDS-DAO, specifically question 15, correlates well with the clinician diagnosis of marked distress and may be an appropriate tool for evaluating treatment benefit in the FOD population.

Vestibular tissue changes following administration of intravaginal prasterone: a vulvoscopic open-label pilot study in menopausal women with dyspareunia.

Background: Prasterone, an intravaginal dyspareunia treatment in menopausal women, improves vaginal health through intracellular conversion of dehydroepiandrosterone into androgens and estrogens. Phase 3 trials for prasterone showed significant improvement in vaginal tissue health and reduction of pain. Aim: To assess vestibular changes with daily use of intravaginal prasterone in menopausal women with moderate to severe dyspareunia. Methods: This open-label prospective pilot study was conducted over 20 weeks. It included 11 menopausal women (median age, 56 years) who were treated daily with intravaginal inserts of 6.5-mg prasterone and assessed monthly. During vulvoscopy, vestibular pain was assessed by cotton-tipped swab testing, and vestibular and vaginal health was independently assessed with the Visual Scale (VS). In addition, vulvoscopic photographs were obtained and assessed via the Vulvoscopic Genital Tissue Appearance (VGTA) scale to evaluate overall genital tissue health. Mean changes from baseline for genital tissue health and pain assessments were analyzed by repeated measures 1-way analysis of variance, followed by a Dunnett post hoc test. Sexual event diaries were completed and adverse events recorded. Outcomes: Outcomes included indices of genital tissue health: pain assessment by cotton-tipped swab testing, VS of the vestibule and vagina, VGTA, and sexual event diary. Results: Aggregate scores from the cotton-tipped swab test progressively improved, reaching statistical significance at week 16, which was maintained through week 20 (-7.27, P = .019). VS scores significantly improved from baseline by week 4 and were maintained through week 20 for the vestibule (-3.00, P = .004) and vagina (-4.00, P = .002). An overall 1607 vulvoscopic photographs were examined; all showed reduction in vestibular erythema and pallor at the end of the study. The mean change from baseline at week 20 for the VGTA score was -7.9 (P = .0016). Intercourse associated with pain was reduced from 81.3% of initiated events during the first month of the study to 8.3% during the last month. Sexual activities that were discontinued due to discomfort were reduced from 45.8% to 6.3%. No prasterone-related serious adverse events were reported. Clinical Implications: Prasterone, a safe and effective intravaginal hormone treatment, significantly improves vestibular health parameters. Strengths and Limitations: Strengths are the prospective study design and the use of multiple outcome measures to assess vestibular tissue health and pain associated with sexual activity. Limitations are the small study cohort and use of nonvalidated outcome measures. Conclusion: Our findings suggest that intravaginal prasterone exerts biologic activity on the androgenic endodermal vestibule, as the medication passes from vagina to vestibule, resulting in amelioration of pain associated with sexual activity.

Global Fund collusion with liquor giant is a clear conflict of interest.

Alcohol is the third leading contributor to death and disability in South Africa, where SABMiller is the major supplier of malt beer, the most popular beverage consumed. The Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund) has recently included SABMiller as a recipient of funding for an education intervention aimed at minimizing alcohol-related harm, including HIV prevention, among men in drinking establishments. Global Fund support for this initiative is cause for concern. It is debatable whether these men are the best target group for the intervention, whether a drinking establishment is the best location, and whether the educational intervention itself is effective. Our experience is that the liquor industry is inclined to support alcohol interventions that will not affect drinking rates at a population level. These interventions allow the industry to simultaneously fulfil social and legal obligations to address the harmful use of alcohol while ensuring that sales and profits are maintained. Providing funding for a highly profitable industry that could afford to fund its own interventions also reduces the funds available for less well-resourced organizations. Do we take it that the problem of "corporate capture" has now spread to one of the largest health funders in the world?

Should We Call It a Prostate? A Review of the Female Periurethral Glandular Tissue Morphology, Histochemistry, Nomenclature, and Role in Iatrogenic Sexual Dysfunction.

INTRODUCTION: There is evidence of glandular tissue within the region of the anterior vaginal wall-female periurethral tissue (AVW-FPT) having similar morphology and immunohistochemistry to the prostate in men and having physiological roles in the female sexual response (FSR). Whether this tissue should be called a prostate in women has been debated. Iatrogenic injury to structures of the AVW-FPT, including these glands and the associated neurovasculature, could be a cause of female sexual dysfunction (FSD). OBJECTIVES: To consolidate the current knowledge concerning the glandular tissue surrounding the urethra in women, evidence was reviewed to address whether: (i) these glands comprise the prostate in women, (ii) they have specific functions in the FSR, and (iii) injury to the AVW-FPT and prostate has sexual dysfunction as a likely outcome. METHODS: A literature review was conducted using keywords including female prostate, Skene's/paraurethral glands, periurethral tissue, Gräfenberg (G)-spot, female ejaculation, mid-urethral sling (MUS), and sexual dysfunction. RESULTS: Histological and immunohistochemical studies of the glandular tissue surrounding the urethra support the existence of prostate in women. Evidence suggests this tissue may have physiologically and clinically relevant autonomic and sensory innervation, and during sexual arousal may contribute to secretions involved in ejaculation and orgasm. Gaps in knowledge relating to the functional anatomy, physiological roles, and embryological origins of this tissue have impeded the acceptance of a prostate in women. Injury to the innervation, vasculature, and/or glandular tissue within the surgical field of MUS implantation suggests iatrogenic sexual dysfunction is plausible. CONCLUSIONS: Continuing to advance our understanding of the morphology, histochemistry, and physiologic capacity of this glandular tissue will clarify the characterization of this tissue as the "prostate" involved in the FSR, and its role in FSD following surgical injury.

International Society for the Study of Women's Sexual Health Clinical Practice Guideline for the Use of Systemic Testosterone for Hypoactive Sexual Desire Disorder in Women.

Background: The Global Consensus Position Statement on the Use of Testosterone Therapy for Women (Global Position Statement) recommended testosterone therapy for postmenopausal women with hypoactive sexual desire disorder (HSDD). Aim: To provide a clinical practice guideline for the use of testosterone including identification of patients, laboratory testing, dosing, post-treatment monitoring, and follow-up care in women with HSDD. Methods: The International Society for the Study of Women's Sexual Health appointed a multidisciplinary panel of experts who performed a literature review of original research, meta-analyses, review papers, and consensus guidelines regarding testosterone use in women. Consensus was reached using a modified Delphi method. Outcomes: A clinically useful guideline following a biopsychosocial assessment and treatment approach for the safe and efficacious use of testosterone in women with HSDD was developed including measurement, indications, formulations, prescribing, dosing, monitoring, and follow-up. Results: Although the Global Position Statement endorses testosterone therapy for only postmenopausal women, limited data also support the use in late reproductive age premenopausal women, consistent with the International Society for the Study of Women's Sexual Health Process of Care for the Management of HSDD. Systemic transdermal testosterone is recommended for women with HSDD not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. Current available research supports a moderate therapeutic benefit. Safety data show no serious adverse events with physiologic testosterone use, but long-term safety has not been established. Before initiation of therapy, clinicians should provide an informed consent. Shared decision-making involves a comprehensive discussion of off-label use, as well as benefits and risks. A total testosterone level should not be used to diagnose HSDD, but as a baseline for monitoring. Government-approved transdermal male formulations can be used cautiously with dosing appropriate for women. Patients should be assessed for signs of androgen excess and total testosterone levels monitored to maintain concentrations in the physiologic premenopausal range. Compounded products cannot be recommended because of the lack of efficacy and safety data. Clinical Implications: This clinical practice guideline provides standards for safely prescribing testosterone to women with HSDD, including identification of appropriate patients, dosing, and monitoring. Strengths & Limitations: This evidence-based guideline builds on a recently published comprehensive meta-analysis and the Global Position Statement endorsed by numerous societies. The limitation is that testosterone therapy is not approved for women by most regulatory agencies, thereby making prescribing and proper dosing challenging. Conclusion: Despite substantial evidence regarding safety, efficacy, and clinical use, access to testosterone therapy for the treatment of HSDD in women remains a significant unmet need.
