Relationship between changes in vulvar-vaginal atrophy and changes in sexual functioning

Sexual health and contraception in the menopause journey

Women may experience changes in sexuality across menopause, because at this step in life hormone deficiency interacts with several determinants in a bio-psycho-social perspective. Healthcare providers should inform women about menopause impact on sexuality and be proactive during consultation in disclosing sexual concerns that would require a targeted assessment. Sexual symptoms become more frequent as women age, but they do not always translate into sexual dysfunction diagnosis, for which distress is required. It is important to recognize conditions that may increase the risk of dysfunctional response to menopause challenges in order to promote sexual longevity through counselling and specific management. In this review, we report key elements for a comprehensive assessment of sexual health around menopause, with a focus on genitourinary syndrome of menopause (GSM) and hypoactive sexual desire disorder (HSDD), representing well identified clinical conditions affecting sexuality at midlife and beyond. We also address the issue of contraception across the menopausal transition, highlighting risks and benefits, and possible implications on sexual function.

Effects of preoperative intravaginal estrogen on pelvic floor disorder symptoms in postmenopausal women with pelvic organ prolapse

BACKGROUND

Menopause and the decline in systemic estrogen are associated with the development of pelvic floor disorders, such as prolapse, urinary incontinence, overactive bladder, and vulvovaginal atrophy symptoms. Past evidence suggests that postmenopausal women with symptomatic prolapse gain benefit from the preoperative application of intravaginal estrogen, but it is unknown whether they would experience improvement in other pelvic floor symptoms when treated with intravaginal estrogen.

OBJECTIVE

This study aimed to determine the effects of intravaginal estrogen (compared with placebo) on stress and urgency urinary incontinence, urinary frequency, sexual function and dyspareunia, and vaginal atrophy symptoms and signs in postmenopausal women with symptomatic prolapse.

STUDY DESIGN

This was a planned ancillary analysis of a randomized, double-blind trial, "Investigation to Minimize Prolapse Recurrence Of the Vagina using Estrogen," which included participants with ≥stage 2 apical and/or anterior prolapse scheduled for transvaginal native tissue apical repair at 3 US sites. The intervention was 1 g conjugated estrogen intravaginal cream (0.625 mg/g) or identical placebo (1:1), inserted nightly for 2 weeks and then twice weekly for ≥5 weeks total before surgery and continued twice weekly for 1 year postoperatively. For this analysis, question responses were compared from participants' baseline and preoperative visits: lower urinary tract symptoms (Urogenital Distress Inventory-6 Questionnaire); sexual health questions, including dyspareunia (Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire-IUGA-Revised); and atrophy-related symptoms (dryness, soreness, dyspareunia, discharge, and itching; each scored 1-4, 4 being quite a bit bothersome). Masked examiners assessed vaginal color, dryness, and petechiae (each scored 1-3, total range 3-9, with 9 being the most estrogenized appearing). Data were analyzed by intent to treat and "per protocol" (ie, those adherent with ≥50% of expected intravaginal cream use, per objective tube before and after weights).

RESULTS

Of 199 participants randomized (mean age of 65 years) and contributing baseline data, 191 had preoperative data. The characteristics were similar between groups. Total Urogenital Distress Inventory-6 Questionnaire scores showed minimal change during this median time of 7 weeks between baseline and preoperative visits, but for those with at least moderately bothersome baseline stress urinary incontinence (32 in the estrogen group and 21 in the placebo group), 16 (50%) in the estrogen group and 9 (43%) in the placebo group showed improvement (P=.78). In addition, 43% of participants in the estrogen group and 31% of participants in the placebo group showed improvement in urgency urinary incontinence (P=.41), and 41% of participants in the estrogen group and 26% of participants in the placebo group showed improvement in urinary frequency (P=.18). There was minimal change in the Pelvic Organ Prolapse/Incontinence Sexual Function Questionnaire-IUGA-Revised scores among sexually active women; dyspareunia rates did not differ between intravaginal estrogen and placebo at the preoperative assessment: 42% and 48%, respectively (P=.49). The maximum score for most bothersome atrophy symptom (among those with baseline symptoms and adherent to study cream) improved slightly more with intravaginal estrogen (adjusted mean difference, -0.33 points; 95% confidence interval, -0.98 to 0.31), but this was not statistically significant (P=.19). However, on examination, among adherent participants, objective signs of atrophy were more improved with intravaginal estrogen treatment (+1.54 vs +0.69; mean difference, 0.85; 95% confidence interval, 0.05-1.65; P=.01).

CONCLUSION

Despite objective changes in the vaginal epithelium consistent with increased estrogenization among drug-adherent participants, the results were inconclusive regarding whether 7 weeks of preoperative intravaginal estrogen cream in postmenopausal women with symptomatic pelvic organ prolapse was associated with improved urinary function, sexual function, dyspareunia symptoms, and other symptoms commonly attributed to atrophy. Additional study is needed.

Quality of life analysis measured with the Cervantes 16 scale in treated menopausal women with genitourinary syndrome

Aim: To assess the quality of life of menopausal women with genitourinary syndrome receiving local drugs (prasterone, estriol or promestriene). Methods: Prospective, longitudinal, randomized study in which quality of life was assessed using the 16-item Cervantes scale (EC16) before and after treatment. Results: A total of 45 women were assessed (35.6% received prasterone, 33.3% estriol and 31.1% promestriene). After treatment, statistically significant mean score differences were observed in EC16, mainly with prasterone. Improvement in EC16 score only shows a statistically significant relationship with age and drug use. Conclusion: The EC16 is an affordable and quick-to-apply tool that allows physicians and patients to know patients' self-perceived quality of life. Local treatment has been shown to improve the quality of life of menopausal patients with genitourinary syndrome.

Bazedoxifene plus conjugated estrogens improve menopausal symptoms in postmenopausal women: a systematic review and meta-analysis

Our aim is to evaluate the efficacy of bazedoxifene (BZA) plus conjugated estrogens (CE) on menopausal symptoms in postmenopausal women. A series of databases including PubMed, EMBASE, Medline, Web of science, China national knowledge internet and Wanfang database up to 31 October 2021 were searched, and randomized controlled trials (RCTs) of BZA/CE for menopausal symptoms were included. Seven RCTs involving 5431 patients were included in this study. Compared with placebo group, there were significantly reduce in daily number of hot flushes, daily number of moderate or severe hot flushes, the percentages of parabasal cells and the time to fall sleep when patients treated with BZA/CE. Besides, there were significant improvement in sleep disturbance and total MENQOL. However, no significant improvements in sleep adequacy were observed in the three groups. Furthermore, BZA 20 mg/CE 0.625 mg was more effective than BZA 20 mg/CE 0.45 mg in improving the menopausal symptoms. Therefore, both bazedoxifene 20 mg plus conjugated estrogens 0.45 mg and bazedoxifene 20 mg plus conjugated estrogens 0.625 mg could significantly improve the menopause-related symptoms and MENQOL in postmenopausal women, and the curative effects of BZA 20 mg/CE 0.625 mg were better than that of BZA 20 mg/CE 0.45 mg. These findings need to be further confirmed by more high-quality RCTs.

Where does postmenopausal dyspareunia hurt? A cross-sectional report

OBJECTIVE

A common symptom of genitourinary syndrome of menopause (GSM) is dyspareunia, attributed to vulvovaginal atrophy. Our objective was to systematically describe the pain characteristics and anatomic locations of tenderness in a cohort with moderate/severe dyspareunia likely due to GSM.

METHODS

This cross-sectional study reports the baseline data of postmenopausal women with dyspareunia screened for an intervention trial of topical estrogen. Postmenopausal women not using hormone therapy who had moderate or severe dyspareunia were eligible if estrogen was not contraindicated. Biopsychosocial assessments were performed using the Vulvar Pain Assessment Questionnaire, and participants underwent a systematic vulvovaginal examination that included a visual assessment and cotton swab testing for tenderness rated using the Numerical Rating Scale (0-10). Vaginal pH and mucosal sensitivity were assessed; pelvic floor muscles and pelvic viscera were palpated for tenderness.

RESULTS

Fifty-five eligible women were examined between July 2017 and August 2019. Mean age was 59.5 ± 6.8 years, and duration of dyspareunia was 6.2 ± 4.3 years. The mean intercourse pain score was 7.3 ± 1.8, most often described as "burning" and "raw." Ninety-eight percent had physical findings of vulvovaginal atrophy. Median pain scores from swab touch at the vulvar vestibule (just outside the hymen) were 4 to 5/10, and topical lidocaine extinguished pain. Median vaginal mucosal pain was zero.

CONCLUSIONS

Participants described their pain as "burning" and "dry." Tenderness was most severe and most consistently located at the vulvar vestibule. Correlating the symptom of dyspareunia with genital examination findings may further our understanding of treatment outcomes for GSM.

The role of hormone therapy in urogenital health after menopause

Menopause represents an endocrine challenge to urogenital health, as oestrogens deprivation and androgens decline significantly contributes to age-related involution of vulvovaginal tissues and lower urinary tract. Genitourinary syndrome of menopause (GSM) is a clinical entity including the chronic and progressive condition of vulvovaginal atrophy (VVA) and encompassing both anatomical and functional consequences of menopause. The term GSM describes genital, sexual and urinary symptoms with a detrimental impact on quality of life (QOL). Several treatment options are available, but many barriers are still present to adequately diagnose and treat GSM. This review aims to present current evidences about epidemiology, aetiology, diagnosis and treatment of GSM, with a focus on prescription medications [low-dose local oestrogen therapy (LET), prasterone (DHEA) and the SERM ospemifene] for urogenital symptoms in healthy postmenopausal women and in special populations, including women with premature ovarian insufficiency (POI) and breast cancer survivors (BCS).

Association between postmenopausal vulvovaginal discomfort, vaginal microbiota, and mucosal inflammation

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.

[Genitourinary menopause syndrome. Postmenopausal women management: CNGOF and GEMVi clinical practice guidelines]

INTRODUCTION

Genitourinary menopause syndrome (SGUM) is defined as a set of symptoms associated with a decrease of estrogen and other sexual steroids during menopause. The main symptoms are vulvovaginal (dryness, burning, itching), sexual (dyspareunia), and urinary (urinary infections, pollakiuria, nycturia, pain, urinary incontinence by urgenturia). SGUM leads to an alteration of the quality of life, and affects especially women's sexuality.

OBJECTIVE

The objective of this review was to elaborate guidelines for clinical practice regarding the management of SGUM in postmenopausal women, and in particular, in women with a history of breast cancer, treated or not with hormone therapy.

MATERIALS AND METHODS

A systematic review of the literature on SGUM management was conducted on Pubmed, Medline and Cochrane Library. Recommendations from international scholarly societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, The North American Menopause Society (NAMS) https://www.menopause.org, Canadian Menopause Society https://www.sigmamenopause.com, European Menopause and Andropause Society (EMAS) https://www.emas-online.org, International Society for the Study of Women's Sexual Health (ISSWSH) https://www.isswsh.org.

RESULTS

Vaginal use of lubricants, moisturizers and hyaluronic acid improves the symptoms of SGUM and may be offered to all patients. For postmenopausal women, local estrogen will be preferred to the oral route because of their safety and efficacy on all symptoms of SGUM during low-dose use. Prasterone is a local treatment that can be proposed as an effective alternative for the management of dyspareunia and sexual function disorder. Current data on oral testosterone, tibolone, oral or transdermal DHEA and herbal medicine are currently limited. Ospemifène, which has shown a significant improvement in sexual symptoms, is not currently marketed in France. In the particular case of women with a history of breast cancer, non-hormonal regimens are a first-line therapy. Current data on the risk of breast cancer recurrence when administering low-dose local estrogen are reassuring but do not support a conclusion that this treatment is safe.

CONCLUSION

SGUM is a common symptom that can affect the quality of life of postmenopausal women. A treatment should be systematically proposed. Local non-hormonal treatment may be offered in all women. Local low-dose estrogen therapy and Prasterone has shown an interest in the management of symptoms. In women before a history of breast cancer, local non-hormonal treatment should be offered first-line. The safety of low-dose local estrogen therapy and Prasterone cannot be established at this time. Other alternatives exist but are not currently recommended in France due to lack of data.

Impact of Vulvovaginal Symptoms in Women Diagnosed with Cancer: A Psychometric Evaluation of the Day-to-Day Impact of Vaginal Aging Questionnaire

Background: Vulvovaginal symptoms (VVS), such as dyspareunia, dryness, and itching, are common following cancer treatment and can negatively impact sexual well-being, daily activities, mood, self-concept, and overall quality of life. Information about the impact of VVS after cancer treatment is scarce, mainly because of a dearth of validated measures. This study aimed to validate the Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire, which assesses impact of VVS on women's lives, in a sample of women with cancer. Methods: Women diagnosed with cancer (n = 202) completed a questionnaire package, including the DIVA and measures of VVS, sexual function, and sexual distress. Data were collected as part of study evaluating an educational workshop. Confirmatory factor analysis (CFA) was used to examine whether the factor structure of the DIVA in this population reflected that of the original validation study. Results: CFA showed that the DIVA assesses VVS impact on four domains: activities of daily living, sexual functioning, emotional well-being, and self-concept and body image. All subscales showed excellent internal consistency reliability; however, item analyses indicated that items in the activities of daily living subscale showed very low means. Correlations with sexual function and distress provided evidence that the DIVA assesses impact of VVS. Conclusions: This is the first study aimed at validating the DIVA in women treated for cancer. Results provide evidence of the DIVA's utility in assessing the impact of VVS on four relevant domains. Although issues with certain scale items need to be resolved in future research, the DIVA provides opportunity to understand the impact of VVS after cancer treatment, to address unmet needs of cancer survivors.

A critical appraisal of vasomotor symptom assessment tools used in clinical trials evaluating hormone therapy compared to placebo

OBJECTIVE

Vasomotor symptoms (VMS) have been consistently reported as the leading predictor of health-related quality of life (HRQOL) among menopausal women, and the strongest indication for treatment. The North American Menopause Society endorses the use of oral estrogen for the treatment of VMS based on a Cochrane meta-analysis. The Cochrane review concludes that oral hormone therapy reduces the frequency and severity of VMS. The objective of this review is to critically appraise the outcome measures used in these clinical trials to evaluate whether there is adequate evidence that oral hormone therapy improves HRQOL.

METHODS

Each trial in the 2004 Cochrane review of oral hormone therapy for the management of VMS was evaluated with respect to study design, outcome measures, and method of analysis.

RESULTS

Twenty-four randomized, double-blind, placebo-controlled clinical trials were appraised. Six trials were excluded from the Cochrane meta-analysis due to inadequate reporting of outcome measures. Of the remaining trials, 15 trials assessed only symptom frequency and/or severity. One trial used a subscale of the General Health Questionnaire. Two trials used the Greene Climacteric Scale, a validated outcome measure in menopausal women, to directly assess the impact of hormone therapy on HRQOL. Both studies showed an improvement in HRQOL in the hormone-treated group, although the sample size was small (n = 118) and the effect was modest.

CONCLUSION

Although oral hormone therapy improves VMS scores, there is a paucity of evidence on whether it improves HRQOL in menopausal women. Future studies using validated, patient-reported outcome measures that directly assess HRQOL are needed.

The impact of genitourinary syndrome of menopause on well-being, functioning, and quality of life in postmenopausal women

OBJECTIVE

Symptoms of genitourinary syndrome of menopause (GSM) are bothersome to middle-aged and older women, and affect their quality of life (QoL), sexuality, and daily activities. The objective of the study was to evaluate the impact of vaginal symptoms and GSM on the well-being, functioning, and QoL of postmenopausal women from Spain.

METHODS

This study involved 423 postmenopausal women participating in the GENISSE study (a multicenter, cross-sectional, descriptive, observational study) who presented at least 1 vaginal symptom. All women completed the "day-to-day impact of vaginal aging" (DIVA) questionnaire. Analysis of total scores and subdomains of the questionnaire were performed in women diagnosed with GSM and those without the condition.

RESULTS

In these women, the highest mean scores on the DIVA questionnaire were found in the sexual functioning domain long version (mean 1.8; SD 1.0), followed by the sexual functioning domain short version (mean 1.7; SD 1.1), self-perception and body image (mean 1.4; SD 1.1), activities of daily living (mean 0.7; SD 0.8), and emotional well-being (mean 0.7; SD 0.8) scales. A total of 299 women (70.7%) had vaginal symptoms with a diagnosis of GSM, whereas 124 (29.3%) had no GSM diagnosis. Scores on the DIVA questionnaire were significantly higher in women with a diagnosis of GSM than in those without this condition.

CONCLUSIONS

Vaginal symptoms impact the well-being, functioning, and QoL of postmenopausal women, especially sexual function, self-perception, and body image. This impact is significantly higher in women with GSM. Identifying and treating patients affected by vaginal symptoms and GSM may be beneficial for improving their QoL.

The experience of genitourinary syndrome of menopause (GSM) among Thai postmenopausal women: the non-reporting issue

Genitourinary syndrome of menopause (GSM) is common among postmenopausal women, but, in general, not all of the patients seek medical advice as this sensitive issue can cause them embarrassment.

OBJECTIVES

To explore the prevalence of GSM among Thai postmenopausal women and their disclosure of and attitude towards GSM.

METHODS

A questionnaire was used to obtain information on GSM from 499 Thai postmenopausal women who attended the Menopause Clinic at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand, from November 2015 to August 2016.

RESULTS

The mean age of the 499 participants was 57.8 ± 7.2 years. It was notable that 87.2% of them had had GSM, and the prevalence increased with age. The most common symptoms were nocturia (77.7%) and vaginal dryness (51.7%). Among the symptomatic patients, 63.0% conveyed their problem to other people, i.e., friends and family, while 52.9% of them never reported to health care providers. The most common reason for not talking about their GSM was the acceptance of it being part of the natural aging process.

CONCLUSIONS

GSM is common among Thai postmenopausal women. The prevalence of non-reporting is high and underreported.

Treatment of genitourinary syndrome of menopause: the potential effects of intravaginal ultralow-concentration oestriol and intravaginal dehydroepiandrosterone on quality of life and sexual function

The climacteric is considered a natural phase in a woman's aging process and is defined as the period starting from the decline in ovarian activity until after the end of ovarian function. Genitourinary syndrome of menopause (GSM) is commonly observed in menopausal women and is characterised by a collection of symptoms resulting from changes to the internal and external genitalia as well as the lower urinary tract. Several studies have demonstrated the close association between sexual dysfunction and symptoms related to GSM. Many medications, at different doses, have been studied over the years for the treatment of the symptoms of GSM. More specifically, ultralow-dose intravaginal oestriol and intravaginal dehydroepiandrosterone (DHEA) are reported to improve symptoms, signs, and quality of life of women with GSM, and they are safe owing to their specific local effect. While the dosage and the administration of intravaginal DHEA are well defined, the literature on intravaginal oestriol is less uniform: different doses and times of administration are proposed with different possible combinations with other non-pharmacological therapies, although a more standardised treatment may be necessary. The aim of this review is to summarise the available data about the effects of ultralow-concentration oestriol and intravaginal DHEA on the menopause-related symptoms, quality of life, and sexual function of women affected by GSM.

Tissue-selective Estrogen Complex for Menopausal Hormone Therapy

The first approved tissue-selective estrogen complex is a pairing of conjugated estrogen combined with the selective estrogen-receptor modulator, bazedoxifene. Advantages include relief of menopausal symptoms without the increased chance of bleeding or breast tenderness unlike with traditional estrogen-progestin therapy, which is associated with both bleeding and breast tenderness. Tissue-selective estrogen complex effects on relief of vasomotor symptoms, prevention of bone loss, improvement in vaginal symptoms, lack of significant cardiovascular effects beyond the expected 2-fold increase in venous thrombosis, neutral effect on breast, and protective effects on the endometrium are discussed.

Addressing Vulvovaginal Atrophy (VVA)/Genitourinary Syndrome of Menopause (GSM) for Healthy Aging in Women

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.

What do TSECs provide in the menopausal hormone therapy?

Tissue-selective estrogen complex (TSEC) is projected as a progestogen-free option for the treatment of estrogen deficiency symptoms in postmenopausal, non-hysterectomized women. TSEC combines the benefits of estrogen with a selective estrogen receptor modulator (SERM), in this case bazedoxifene acetate (BZA), which has an antagonistic effect on the endometrium, thus avoiding the use of progestins. The authorized TSEC combination (conjugated estrogens [CE] 0.45 mg/BZA 20 mg) for the alleviation of vasomotor symptoms has been demonstrated in randomized clinical trials compared with placebo or menopausal hormone therapy (MHT). In addition, TSEC has shown improvements in quality of life and vaginal atrophy. In respect to MHT using progestins, the benefits of TSEC are found mainly in the bleeding pattern, amenorrhea rate, and reduction in mammary repercussion (i.e., breast tenderness and radiological density). The objective of this guide will be to analyze the efficacy and safety of TSEC consisting of CE/BZA in postmenopausal women.

Efficacy of Vaginal Estradiol or Vaginal Moisturizer vs Placebo for Treating Postmenopausal Vulvovaginal Symptoms: A Randomized Clinical Trial

IMPORTANCE

Nearly half of postmenopausal women report bothersome vulvovaginal symptoms, but few data support the efficacy of 2 commonly recommended treatments.

OBJECTIVE

To compare the efficacy of a low-dose vaginal estradiol tablet and a vaginal moisturizer, each vs placebo, for treatment of moderate-to-severe postmenopausal vulvovaginal symptoms.

DESIGN, SETTING, AND PARTICIPANTS

This 12-week multicenter randomized clinical trial enrolled postmenopausal women with moderate to severe symptoms of vulvovaginal itching, pain, dryness, irritation, or pain with penetration.

INTERVENTIONS

Vaginal 10-μg estradiol tablet (daily for 2 weeks, then twice weekly) plus placebo gel (3 times a week) (n = 102) vs placebo tablet plus vaginal moisturizer (n = 100) vs dual placebo (n = 100).

MAIN OUTCOMES AND MEASURES

The main outcome was decrease in severity (0-3) of most bothersome symptom (MBS) between enrollment and 12 weeks. Additional measures included a composite vaginal symptom score, Female Sexual Function Index (FSFI) score (2-36), modified Female Sexual Distress Score-Revised item 1, treatment satisfaction and meaningful benefit, Vaginal Maturation Index, and vaginal pH.

RESULTS

The 302 women had a mean (SD) age of 61 (4) years and were primarily white (267 [88%]), college educated (200 [66%]), and sexually active (245 [81%]). Most women (294 [97%]) provided data for the primary analysis. The most commonly reported MBS was pain with vaginal penetration (182 [60%]), followed by vulvovaginal dryness (63 [21%]). Mean baseline MBS severity was similar between treatment groups: estradiol, 2.4 (95% CI, 2.3 to 2.6); moisturizer, 2.5 (95% CI, 2.3 to 2.6); placebo, 2.5 (95% CI, 2.4 to 2.6). All treatment groups had similar mean reductions in MBS severity over 12 weeks: estradiol, -1.4 (95% CI, -1.6 to -1.2); moisturizer, -1.2 (95% CI, -1.4 to -1.0); and placebo, -1.3 (95% CI, -1.5 to -1.1). No significant differences were seen between estradiol (P = .25) or moisturizer (P = .31) compared with placebo. Mean total FSFI improvement was similar between estradiol (5.4; 95% CI, 4.0 to 6.9) and placebo (4.5; 95% CI, 2.8 to 6.1) (P = .64), and between moisturizer (3.1; 95% CI, 1.7 to 4.5) and placebo (P = .17).

CONCLUSIONS AND RELEVANCE

Our results suggest that neither prescribed vaginal estradiol tablet nor over-the-counter vaginal moisturizer provides additional benefit over placebo vaginal tablet and gel in reducing postmenopausal vulvovaginal symptoms.
