Comparison of promestriene with vaginal fractional CO2 laser and radiofrequency treatments of genitourinary syndrome of menopause. Maturitas 2024; 186:108008. [PMID: 38714422 DOI: 10.1016/j.maturitas.2024.108008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 04/09/2024] [Accepted: 04/21/2024] [Indexed: 05/09/2024]
Abstract
OBJECTIVE To compare the effects of fractional CO2 laser and microablative fractional radiofrequency treatment with promestriene topical estrogen on sexual function and genitourinary syndrome of menopause symptoms. METHODS This was a prospective randomized open-label clinical trial conducted with 62 postmenopausal women assigned to three intervention groups: a) topical promestriene for 90 days (n = 17); b) fractional CO2 laser treatment (n = 24); and c) microablative fractional radiofrequency treatment (n = 21). Each of the latter two groups underwent three treatment sessions at 4-week intervals. At baseline and at the end of the study, all participants had a gynecological examination that included vaginal pH measurement, and the completion of the Vaginal Symptom Score, the Vaginal Health Index, and the Female Sexual Function Index. For the energy treatment groups, adverse effects were evaluated after each session. Group homogeneity was assessed at baseline, and results were evaluated over time (from baseline to the end of treatment) and between groups over time. RESULTS All baseline parameters were similar among studied groups. At the end of the study, all 3 treatments had produced similar effects: a reduction of vaginal pH, and an improvement of vulvovaginal symptoms (Vaginal Symptom Score and Vaginal Health Index scores) as well as sexual function (higher total Female Sexual Function Index scores, and in the desire, arousal, lubrication and pain domain scores), with no differences observed between groups. Side-effects were slight for both energy treatment groups, mainly represented by vaginal discharge. CONCLUSION The present study suggests that the two energy treatments were efficient along with promestriene at improving postmenopausal genitourinary and sexuality symptoms. Clinical trial identification numberNCT04717245.

Genitourinary syndrome of lactation: a new perspective on postpartum and lactation-related genitourinary symptoms. Sex Med Rev 2024; 12:279-287. [PMID: 38757214 DOI: 10.1093/sxmrev/qeae034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/16/2024] [Accepted: 04/25/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND The genitourinary syndrome of menopause (GSM) is a well-documented condition characterized by a range of genitourinary symptoms in peri- and postmenopausal women. As with GSM, postpartum lactating women experience reduced estrogen and androgen levels. However, there is limited research on the impact of symptoms during the postpartum breastfeeding period. OBJECTIVES The aim was to review the literature for genitourinary health in the postpartum breastfeeding population and summarize key findings and potential treatments. METHODS We performed a comprehensive literature review in PubMed, Google Scholar, and Scopus from inception of database to November 2023 using the following keywords individually and in combination: "physiology of postpartum" or "physiology of lactogenesis" or "vulvovaginal health" or "vaginal atrophy" or "vaginal dryness" or "dyspareunia" or "urinary incontinence" or "lactation" or "breastfeeding" or "vaginal estrogen." All identified articles published in English were considered. Relevant studies were extracted, evaluated, and analyzed. The work presented in this article represents a summative review of the identified literature. RESULTS During lactation, high levels of prolactin inhibit estrogen and androgen secretion via negative feedback, which leads to an increased prevalence of vulvovaginal atrophy, vaginal dryness, dyspareunia, and urinary incontinence in lactating postpartum women. Despite these highly prevalent and potentially devastating symptoms, there is a lack of consistent screening at postpartum visits and no treatment guidelines available to health care providers. CONCLUSION Postpartum breastfeeding women experience similar physiology and symptoms to the postmenopausal phase, as seen in GSM. We propose the introduction of a novel term to describe the genitourinary changes seen in postpartum breastfeeding individuals: genitourinary syndrome of lactation. The diagnostic use of genitourinary syndrome of lactation will equip health care providers with an all-encompassing term to bring awareness to the symptoms experienced by postpartum breastfeeding individuals and lead to improved screening and treatment for the high numbers of individuals experiencing these genitourinary changes.

Abstract
The human microbiome contains genetic information that regulates metabolic processes in response to host health and disease. While acidic vaginal pH is maintained in normal conditions, the pH level increases in infectious vaginitis. We propose that this change in the vaginal environment triggers the biosynthesis of anti-vaginitis metabolites. Gene expression levels of Chryseobacterium gleum, a vaginal symbiotic bacterium, were found to be affected by pH changes. The distinctive difference in the metabolic profiles between two C. gleum cultures incubated under acidic and neutral pH conditions was suggested to be an anti-vaginitis molecule, which was identified as phenylacetic acid (PAA) by spectroscopic data analysis. The antimicrobial activity of PAA was evaluated in vitro, showing greater toxicity toward Gardnerella vaginalis and Candida albicans, two major vaginal pathogens, relative to commensal Lactobacillus spp. The activation of myeloperoxidase, prostaglandin E2, and nuclear factor-κB, and the expression of cyclooxygenase-2 were reduced by an intravaginal administration of PAA in the vaginitis mouse model. In addition, PAA displayed the downregulation of mast cell activation. Therefore, PAA was suggested to be a messenger molecule that mediates interactions between the human microbiome and vaginal health.

Abstract
This review summarizes our current understanding of associations of the postmenopausal vaginal microbiome with genitourinary syndrome of menopause. We review the normal postmenopausal microbiota, examine the association of the microbiome with vulvovaginal symptoms, describe microbial communities associated with physical and laboratory findings, and report the impact of different treatments for genitourinary syndrome of menopause on microbiota and symptom improvement. Postmenopausal vaginal symptoms have an underlying pathophysiology that has not been fully elucidated. Estrogen treatment may not be sufficient to relieve symptoms of vaginal discomfort in all postmenopausal individuals. In addition, other interventions targeted at changing the microbiota or pH do not consistently improve symptom severity.

Abstract
BACKGROUND Cervical cancer is the fourth most common cancer among women, with persistent high-risk human papillomavirus (HPV) infection being responsible for its progression. In healthy, pre-menopausal women, the vaginal pH value is maintained at 3.8-4.5, but various factors can affect it. Previous studies have suggested the relationship between vaginal pH value and HPV infection. In this study, we aimed to explore the relationship between vaginal pH and susceptibility of HPV infection. METHODS In our study, we retrospectively collected medical information from women who underwent leukorrhea examination at our hospital. We excluded women with infectious diseases or cancer, those who were pregnant or within 6 months post-delivery, and those without HPV test results within 6 months. The association between percentage of HPV infection and vaginal pH value was analyzed. Furthermore, we prepared HPV pseudovirus (PsVs) by co-transfecting structure plasmids and report plasmids in 293FT cells. In vitro, we changed the pH value of cell culture medium to investigate its influence on HPV PsVs infection. In vivo, we changed mouse's vaginal pH value to investigate its influence on HPV PsVs infection. RESULTS Our retrospective study included 3115 women aged 20-78, including 2531 women with HPV negative and 584 women with HPV positive. The percentages of both HPV infection and high-risk HPV infection were higher in women with a vaginal pH value ≥5.0 compared to those with a pH value < 5.0. In vitro, HPV PsVs infection rate was higher in cell culture medium of higher pH value, dominantly due to the influence of pH value on the stage of HPV PsVs adhering to cell surface. Neither of the cell surface HPV receptors Syndecan-1 nor integrin α6 was found to be changed obviously in different pH values. In vivo, more HPV PsVs were adhered to the mouse's vaginal epithelial cells with the increase of the vaginal pH value. CONCLUSIONS Our study suggests a possible association between vaginal pH value and HPV infection. The pH value can influence the susceptibility of HPV PsVs infection by affecting the adhering of HPV PsVs to cells in vivo and in vitro. Additionally, the cell surface HPV receptors Syndecan-1 and Integrin α6 do not seem to be affected by pH value, and the specific mechanism needs to be further explored.

Abstract
The aim of this study is to evaluate changes in vaginal pH and epithelium maturation after erbium-doped yttrium aluminum garnet (Er-YAG) laser treatment, and to assess its safety and efficacy on the symptoms of genitourinary syndrome of menopause (GSM). This was a retrospective study conducted between November 2019 and April 2022 and included 32 women diagnosed with GSM who had not benefitted from lubrication treatment and could not or would not use estrogen. Patients received three sessions of Er- YAG laser. All patient data before and after treatment were obtained from computer records. Vaginal maturation index (VMI), maturation value (MV) and vaginal pH values of the patients before and after laser treatment were compared. We also evaluated post-procedural complications and symptoms. Mean age was 59.72 ± 5.66 years. After laser therapy, there was a significant decrease in vaginal pH (p < 0.001) and the proportion of parabasal cells in VMI (p < 0.001), while there was a significant increase in MV (p < 0.001) and the proportion of superficial cells in VMI (p < 0.001). In 84.4% of the patients, GSM-related symptoms regressed completely or decreased to a tolerable level. Patients in which symptoms disappeared completely had significantly lower mean age (p = 0.002) and duration of menopause (p = 0.009). The laser procedure resulted in complications including mucosal injury in 5 (15.6%) patients (all recovered spontaneously) and vaginal burning sensation in 2 (6.3%) patients. Vaginal Er-YAG laser treatment may be a safe and effective alternative treatment method in a population of women with GSM who do not want to or cannot use estrogen therapy.

Abstract
OBJECTIVE A phase 2 study showed that 15 mg estetrol (E4) alleviates vasomotor symptoms (VMS). Here, we present the effects of E4 15 mg on vaginal cytology, genitourinary syndrome of menopause, and health-related quality of life. METHODS In a double-blind, placebo-controlled study, postmenopausal participants (n = 257, 40-65 y) were randomized to receive E4 2.5, 5, 10, or 15 mg or placebo once daily for 12 weeks. Outcomes were the vaginal maturation index and maturation value, genitourinary syndrome of menopause score, and the Menopause Rating Scale to assess health-related quality of life. We focused on E4 15 mg, the dose studied in ongoing phase 3 trials, and tested its effect versus placebo at 12 weeks using analysis of covariance. RESULTS Least square (LS) mean percentages of parabasal and intermediate cells decreased, whereas superficial cells increased across E4 doses; for E4 15 mg, the respective changes were -10.81% ( P = 0.0017), -20.96% ( P = 0.0037), and +34.17% ( P < 0.0001). E4 15 mg decreased LS mean intensity score for vaginal dryness and dyspareunia (-0.40, P = 0.03, and -0.47, P = 0.0006, respectively); symptom reporting decreased by 41% and 50%, respectively, and shifted to milder intensity categories. The overall Menopause Rating Scale score decreased with E4 15 mg (LS mean, -3.1; P = 0.069) and across doses was associated with a decreasing frequency and severity of VMS ( r = 0.34 and r = 0.31, P < 0.001). CONCLUSIONS E4 demonstrated estrogenic effects in the vagina and decreased signs of atrophy. E4 15 mg is a promising treatment option also for important menopausal symptoms other than VMS.

Abstract
Epithelial surfaces protect exposed tissues in the body against intrusion of foreign materials, including xenobiotics, pollen and microbiota. The relative permeability of the various epithelia reflects their extent of exposure to the external environment and is in the ranking: intestinal≈ nasal ≥ bronchial ≥ tracheal > vaginal ≥ rectal > blood-perilymph barrier (otic), corneal > buccal > skin. Each epithelium also varies in their morphology, biochemistry, physiology, immunology and external fluid in line with their function. Each epithelium is also used as drug delivery sites to treat local conditions and, in some cases, for systemic delivery. The associated delivery systems have had to evolve to enable the delivery of larger drugs and biologicals, such as peptides, proteins, antibodies and biologicals and now include a range of physical, chemical, electrical, light, sound and other enhancement technologies. In addition, the quality-by-design approach to product regulation and the growth of generic products have also fostered advancement in epithelial drug delivery systems.

Abstract
IMPORTANCE More information is needed about the efficacy and safety of compounded bioidentical hormone therapy (cBHT) in the published literature. A thorough synthesis of existing data is not currently available. OBJECTIVE To provide a systematic review and meta-analysis of the existing evidence related to the safety and efficacy of commonly prescribed cBHT preparations in perimenopausal and postmenopausal women. EVIDENCE REVIEW PubMed, ClinicalTrials.gov, and The Cochrane Central Register of Controlled Trials were searched. Randomized controlled trials (RCTs) comparing cBHT with a placebo or FDA-approved products in perimenopausal or postmenopausal women were eligible. The risk of bias was assessed by the Cochrane risk of bias tool. The primary safety outcome was changes in lipid profile and glucose metabolism, and the primary efficacy outcome was the change of vaginal atrophy symptoms. The secondary outcomes included the change of endometrial thickness, risk of adverse events, vasomotor symptoms, change of serum hormone levels, and change of bone mineral density. FINDINGS A total of 29 RCTs reported in 40 articles containing 1,808 perimenopausal and postmenopausal women were included. Two risk factors of cardiovascular disease, lipid profile, and glucose metabolism, were evaluated with cBHT. The results showed that compounded androgen was not associated with change of lipid profile or glucose metabolism. There was no change in endometrial thickness or serious adverse events. There were more androgenic side effects with compounded dehydroepiandrosterone compared with placebo as expected. Other safety measures including clinical cardiovascular events, endometrial biopsy, and risk of breast cancer were not studied. cBHT in the form of compounded vaginal androgen was found to significantly improve vaginal atrophy symptoms (SMD -0.66 [95% CI, -1.28 to -0.04]; I2 = 86.70%). This finding was supported by the association between compounded vaginal androgen and improved female sexual function scores. The changes of serum hormone levels were also evaluated. Despite the variations in absorption from different types of compounded hormones, routes, and strengths, the trends were consistent with published data from FDA-approved products. CONCLUSIONS AND RELEVANCE This review found that cBHT used in primarily short-term RCTs is not associated with adverse changes in lipid profile or glucose metabolism. cBHT in the form of vaginal androgens appears beneficial for vaginal atrophy symptoms. There are insufficient RCTs of cBHT to assess clinical risk of breast cancer, endometrial cancer, or cardiovascular disease. Long-term studies with clinical endpoints are needed.

Abstract
BACKGROUND Half of all postmenopausal women report symptoms of vulvar, vaginal, or urinary discomfort with substantial impact on sexual function and quality of life; underlying mechanisms leading to symptoms are poorly understood. OBJECTIVE To examine the possibility that the vaginal microbiota and/or mucosal immune response contributes to the severity of bothersome vaginal symptoms, we conducted a substudy of samples from a randomized trial of vaginal treatment for genitourinary syndrome of menopause to compare these features between women whose symptoms improved and women whose symptoms did not improve. STUDY DESIGN This is a secondary analysis of samples collected in a 12-week randomized trial of treatment with vaginal estradiol or moisturizer vs placebo for moderate-severe postmenopausal symptoms of vaginal discomfort. We randomly selected 20 women in each arm with ≥2-point decrease in most bothersome symptom severity (responders) and 20 matched controls with ≤1-point decrease (nonresponders). At 0, 4, and 12 weeks, we characterized vaginal microbiota (16S ribosomal RNA gene sequencing), vaginal fluid metabolites (broad-based metabolomic profiling), vaginal fluid-soluble immune markers (Meso Scale Discovery), pH, and vaginal maturation index. We compared responders with nonresponders at baseline and across all visits using linear mixed models to evaluate associations with microbiota, metabolites, and immune markers, incorporating visit and participant-specific random effects while controlling for treatment arm. RESULTS Here, the mean age of women was 61 years (n=120), and most women (92%) were White. At enrollment, no significant differences were observed between responders and nonresponders in age, most bothersome symptom type or severity, microbiota composition or diversity, Lactobacillus dominance, metabolome, or immune markers. There was a significant decrease in diversity of the vaginal microbiota in both responders and nonresponders (P<.001) over 12 weeks. Although this change did not differ by responder status, diversity was associated with treatment arm: more women in the estradiol arm (63%) had Lactobacillus-dominant, lower diversity bacterial communities than women in the moisturizer (35%) or dual placebo (23%) arms (P=.001) at 12 weeks. The metabolome, vaginal maturation index, and measured immune markers were not associated with responder status over the 12 weeks but varied by treatment arm. CONCLUSION Postmenopausal vaginal symptom severity was not significantly associated with vaginal microbiota or mucosal inflammatory markers in this small study. Women receiving vaginal estradiol experienced greater abundance of lactobacilli and lower vaginal pH at end of treatment.

Emulsion-Based Multicompartment Vaginal Drug Carriers: From Nanoemulsions to Nanoemulgels. Int J Mol Sci 2021; 22:ijms22126455. [PMID: 34208652 PMCID: PMC8233730 DOI: 10.3390/ijms22126455] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 06/10/2021] [Accepted: 06/11/2021] [Indexed: 01/05/2023] Open
Abstract
In order to overcome the limitations associated with vaginal administration of drugs, e.g., the short contact time of the drug form with the mucosa or continuous carrier wash-out, the development of new carriers for gynecological use is necessary. Furthermore, high individual anatomical and physiological variability resulting in unsatisfactory therapeutic efficacy of lipophilic active substances requires application of multicompartment drug delivery systems. This manuscript provides an up-to-date comprehensive review of the literature on emulsion-based vaginal dosage forms (EVDF) including macroemulsions, microemulsions, nanoemulsions, multiple emulsions and self-emulsifying drug delivery systems. The first part of the paper discusses (i) the influence of anatomical-physiological conditions on therapeutic efficacy of drug forms after local and systemic administration, (ii) characterization of EVDF components and the manufacturing techniques of these dosage forms and (iii) methods used to evaluate the physicochemical and pharmaceutical properties of emulsion-based vaginal dosage forms. The second part of the paper presents (iv) the results of biological and in vivo studies as well as (v) clinical evaluation of EVDF safety and therapeutic efficacy across different indications.

Variation in outcome reporting and measurement tools in clinical trials of treatments for genitourinary symptoms in peri- and postmenopausal women: a systematic review. ACTA ACUST UNITED AC 2021; 27:1070-1080.

Abstract
IMPORTANCE Genitourinary symptoms affect 40% to 60% of postmenopausal women. Evidence-based approaches to diagnosing and managing these symptoms are limited by inconsistencies in outcomes and measures used in clinical trials. OBJECTIVE The aim of the study was to systematically review all outcomes and measurement tools reported in randomized clinical trials of interventions for genitourinary symptoms associated with menopause. EVIDENCE REVIEW We searched PubMed, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) up to December 2018. Randomized controlled trials with a primary or secondary outcome of genitourinary symptoms associated with menopause, English language, and sample size of 20 or more women per study arm were included. Study characteristics, outcomes, and measurement methods were collected. FINDINGS The search yielded 3,478 articles of which 109 met inclusion criteria. Forty-eight different outcomes were reported with "atrophy" as the most common (56/109, 51%) followed by measures of sexual function (19/109, 17%). Almost all (108/109, 99%) trials included patient-reported measures, with 21 different measures and 39 symptom combinations. Clinician-reported scales of vulvovaginal appearance were used in 36 of 109 (33%) trials, with extensive variation in what was measured and reported. Cytological measures from the vaginal epithelium were the most commonly used objective tools (76/109, 70%). CONCLUSIONS AND RELEVANCE There is heterogeneity in reported outcomes and measures used in clinical trials of treatments for genitourinary symptoms at menopause and uncertainty as to which outcomes best reflect patient priorities and symptoms. The findings from this systematic review have informed an international survey of stakeholders to determine priorities for outcome selection and reporting. This survey will then inform the development of a Core Outcome Set for use in future clinical trials by the COMMA (Core OutcoMes in MenopAuse) consortium. : Video Summary:http://links.lww.com/MENO/A599.

Abstract
Genitourinary syndrome of menopause (GSM) may affect up to 90% of menopausal women, including vulvovaginal atrophy (VVA), burning, pain, bleeding, irritation, dyspareunia, anorgasmia, and urinary symptoms. Vaginal symptoms from lack of estrogens can have a significant impact on the sexual health and quality of life (QoL) in as many as 50% of postmenopausal women. Several therapeutic alternatives, both hormonal and non- hormonal, have been proposed. Microablative CO<inf>2</inf> laser is one of the three non-surgical energy-based therapies, with Erbium:YAG laser and temperature-controlled radiofrequency (RF). Microablative CO<inf>2</inf> laser induces morphological changes in vaginal tissues and results of several clinical trials suggest that this type of laser improves symptoms of GSM. Moreover, this treatment seems to be safe. Given the increasingly widespread use of laser CO<inf>2</inf> as a non-hormonal alternative treatment for GSM, the authors reviewed the current published literature evaluating this therapy, to compare efficacy and safety of different protocols.

Exogenous Reproductive Hormones nor Candida albicans Colonization Alter the Near Neutral Mouse Vaginal pH. Infect Immun 2021; 89:IAI.00550-20.

Abstract
While human vaginal pH in childbearing-age women is conclusively acidic, the mouse vaginal pH is reported as being near neutral. However, this information appears to be somewhat anecdotal with respect to vulvovaginal candidiasis, as such claims in the literature frequently lack citations of studies that specifically address this physiological factor. Given the disparate pH between mice and humans, the role of exogenous hormones and colonization by the fungal pathogen Candida albicans in shaping vaginal pH was assessed. Use of a convenient modified vaginal lavage technique with the pH indicator dye phenol red demonstrated that indeed vaginal pH was near neutral (7.2 ± 0.24) and was not altered by delivery of progesterone or estrogen in C57BL/6 mice. These trends were conserved in DBA/2 and CD-1 mouse backgrounds, commonly used in the mouse model of vaginitis. It was also determined that vaginal colonization with C. albicans did not alter the globally neutral vaginal pH over the course of one week. Construction and validation of a C. albicans reporter strain expressing GFPy, driven by the pH-responsive PHR1 promoter, confirmed the murine vaginal pH to be at least ≥6.0. Collectively, our data convincingly demonstrate a stable and conserved near neutrality of the mouse vaginal pH during vulvovaginal candidiasis and should serve as a definitive source for future reference. Implications and rationale for disparate pH in this model system are also discussed.

Abstract
Introduction: Vulvovaginal atrophy (VVA), a component of the genitourinary syndrome of menopause, is a progressive condition due to decline in estrogen leading to vaginal and vulvar epithelial changes. Accompanying symptoms of dryness, irritation, burning, dysuria, and/or dyspareunia have a negative impact on quality of life. Ospemifene is a selective estrogen receptor modulator (SERM) approved by the FDA for moderate to severe dyspareunia and vaginal dryness due to postmenopausal VVA. Areas covered: PubMed was searched from inception to March 2019 with keywords ospemifene and vulvar vaginal atrophy to review preclinical and clinical data describing the safety and efficacy of ospemifene for vaginal dryness and dyspareunia due to VVA. Covered topics include efficacy of ospemifene on vaginal cell populations, vaginal pH, and most bothersome VVA symptoms; imaging studies of vulvar and vaginal tissues; effects on sexual function; and safety of ospemifene on endometrium, cardiovascular system, and breast. Expert opinion: Ospemifene is significantly more effective than placebo in all efficacy analyses studied, working through estrogen receptors and possibly androgen receptors. Safety as assessed by adverse events was generally comparable to that with placebo and to other SERMs, and/or adverse events were not clinically meaningful. No cases of endometrial or breast cancer were reported.

Addressing Vulvovaginal Atrophy (VVA)/Genitourinary Syndrome of Menopause (GSM) for Healthy Aging in Women. Front Endocrinol (Lausanne) 2019; 10:561.

Abstract
Vaginal health is an essential component of active and healthy aging in women at midlife and beyond. As a consequence of hormonal deprivation and senescence, the anatomy and function of urogenital tissues are significantly affected and vulvovaginal atrophy (VVA) may occur. In a high proportion of postmenopausal women, progressive and chronic VVA symptoms have a strong impact on sexual function and quality of life. The new definition of genitourinary syndrome of menopause (GSM) comprises genital symptoms (dryness, burning, itching, irritation, bleeding), sexual symptoms (dyspareunia and other sexual dysfunctions) and urinary symptoms (dysuria, frequency, urgency, recurrent urinary infections). Many variables (age, sexual activity and partnership status) influence the clinical impact VVA/GSM symptoms and attitudes of elderly women to consult for receiving effective treatments. Psychosocial factors play a critical role in sexual functioning, but the integrity of the urogenital system is as well important affecting many domains of postmenopausal women's health, including sexual function. Several international surveys have extensively documented the need to improve VVA/GSM management because of the strong impact on women's daily life and on couple's intimacy. Health care providers (HCPs) need to be proactive in the early recognition of VVA/GSM in order to preserve urogenital and sexual longevity, by using hormonal and non-hormonal strategies. The clinical diagnosis is based on genital examination to identify objective signs and on the use of subjective scales to rate most bothersome symptoms (MBS), especially vaginal dryness. Recent studies point to the importance of addressing VVA/GSM as a potential early marker of poor general health in analogy with vasomotor symptoms. Therefore, a standard of VVA/GSM care in elderly women is desirable to enhance physical, emotional and mental well-being.
