CO2 laser and the genitourinary syndrome of menopause: a randomized sham-controlled trial

European Board and College of Obstetrics and Gynaecology (EBCOG) position statement on the use of laser vaginal devices for treatment of genitourinary syndrome of menopause, vaginal laxity, pelvic organ prolapse and stress urinary incontinence

One in three women will experience pelvic floor disorders in her lifetime and nearly 60 percent of postmenopausal women are affected by vaginal dryness. Conservative management is recommended as first line treatment for pelvic organ prolapse and stress urinary incontinence. Also, vaginal estrogens are often prescribed for symptomatic vaginal atrophy. Lasers have been used in cosmetic industry for connective tissue remodeling and repair of skin. Their use in the last decade for treating genitourinary symptoms of menopause, pelvic organ prolapse and stress urinary incontinence has gained popularity but there is lack of robust evidence to support its use in routine practice. The European Board and College of Obstetrics and Gynaecology calls for high quality evidence with patient related outcome measures before adopting to routine clinical practice.

Lasers in Gynecology

The first published reports on the use of laser for cervical pathology date back to 1973. Technical advancements in flexible and rigid laser fibers revolutionized video laser laparoscopy in the 1990s. Fractionated lasers have been used to treat vulvovaginal symptoms associated with genitourinary syndrome of menopause, lichen sclerosus, and urinary incontinence. Review of available data suggests that fractionated lasers can improve both subjective and objective signs of vaginal atrophy and lichen sclerosus, but the evidence is weak because most of the trials are underpowered, are at risk for bias, and lack long-term follow-up. There is no strong evidence to support fractionated laser therapy for urinary incontinence or low-level laser therapy for chronic pelvic pain. Although short-term, single-arm trials suggest benefit of fractionated laser therapy for genitourinary syndrome of menopause, lichen sclerosus, and urinary incontinence, additional adequately powered, prospective, randomized, and longer-term comparative trials are needed before lasers can be recommended for these specific conditions. The purpose of this Clinical Expert Series is to review basic laser biophysics and the mechanism of action for modern fractionated lasers as relevant to the gynecologist. We also summarize safety and effectiveness data for lasers used for some of the most commonly studied gynecologic conditions: the vulvovaginal atrophy component of genitourinary syndrome of menopause, lichen sclerosus, and urinary incontinence.

Multifaceted Impact of CO2 Laser Therapy on Genitourinary Syndrome of Menopause, Vulvovaginal Atrophy and Sexual Function

Genitourinary syndrome of menopause (GSM) encompasses a range of distressing symptoms in the vulvovaginal and/or bladder-urethral regions related to menopause changes, negatively influencing woman's quality of life and sexual activity. Fractional micro-ablative CO2 laser therapy has shown the potential to reinstate the vaginal epithelium to a condition akin to the premenopausal state, thereby ameliorating the subjective symptoms associated with GSM. We conducted a prospective, pilot study in 73 sexually active postmenopausal women treated with CO2 laser for their GSM symptoms, while assessing Vaginal Health Index Score (VHIS) and sexual function through the Female Sexual Function Index (FSFI) Questionnaire. The laser treatment resulted in a decrease in VHIS and patient-reported vulvovaginal atrophy (VVA) symptoms, with a significantly lower prevalence of vaginal itching, dryness, and burning (p < 0.001), as well as dyspareunia (p = 0.002). The occurrence of urinary incontinence, urgency, and vaginal heaviness significantly reduced, with an improvement in the staging of cystocele, either to Stage 1 or complete resolution (p < 0.001). FSFI total and domain scores were significantly higher after the treatment, indicating better sexual function, with a post-treatment score median of 25 (p < 0.001). Therefore, using a three-cycle fractional CO2 laser was an effective choice for reducing urogenital discomfort related to GSM in postmenopausal women.

Physical energies for the management of genitourinary syndrome of menopause: An overview of a systematic review and network meta-analysis

BACKGROUND

Energy-based devices (laser and radiofrequency) have been used to treat genitourinary syndrome of menopause (GSM).

OBJECTIVES

To evaluate the efficacy and safety of physical energy use in managing GSM symptoms.

SEARCH STRATEGY

Five databases were searched from inception to December 2022. Language restrictions were not imposed.

SELECTION CRITERIA

We included all Cochrane and non-Cochrane systematic reviews with or without meta-analyses that described postmenopausal women with symptoms of GSM treated with physical energy.

DATA COLLECTION AND ANALYSIS

We performed a network meta-analysis using frequentist methods to calculate standardized mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). Methodological and reporting quality were assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2).

MAIN RESULTS

Nine reviews were included in the overview, six of which were meta-analyses. Four randomized controlled trials, representing 218 participants and nine different study arms, met the criteria for inclusion in our component network meta-analysis. Confidence in review findings was low in six reviews and critically low in three. Our network meta-analysis results showed that premarin (SMD 2.60, 95% CI 7.76-3.43), conjugated estrogens (SMD 2.13, 95% CI 1.34-2.91), carbon dioxide laser (SMD 1.71, 95% CI 1.10-2.31), promestriene (SMD 1.41, 95% CI 0.59-2.24), and vaginal lubricant (SMD 1.37, 95% CI 0.54-2.20) were more effective than sham for reducing sexual dysfunction, with a consequent increase in Female Sexual Function Index (FSFI). Two studies showed a high risk of bias, owing to a lack of blinding.

CONCLUSION

Several gaps in the use of physical energy for managing GSM still need to be addressed. The small number of blind clinical trials made the results fragile.

Safety and efficacy of non-ablative CO2 laser treatment of vulvo-vaginal atrophy in women with history of breast cancer

PURPOSE

Breast cancer survivors (BCS) suffer severe vulvo-vaginal atrophy (VVA) and some of the most effective therapies are contraindicated. In literature we have no data about the non-ablative CO2 laser on these women. The aim of this study was to examine its efficacy, safety and acceptability in BCS.

MATERIALS AND METHODS

The enrolled women underwent 3 sessions of laser therapy (t0, t1, t2) and a one-month follow up examination (t3). At each time point we measured objective signs of VVA via VHI (Vaginal Health Index) and VuHI (Vulvar Health Index) and subjective parameters (Dryness, Burning, Itching, Dysuria) via visual analog scales (VAS). In sexually active women we evaluated the sexual function with FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Score) scores and MENQOL (menopause quality of life questionnaire).

RESULTS

We enrolled 26 BCS. The mean VHI, VuVHI, dryness and burning VAS scores improved significantly and this improvement was not influenced by the initial VVA grade. MENQOL sexual domain, Lubrication, Orgasm and Pain domains and FSFI total score improved significantly, while Desire, Arousal and Satisfaction domains of FSFI and FSDS did not. At t0 women using Aromatase Inhibitors suffered more severe vaginal dryness than women using Tamoxifen or no therapy, but the three subgroups improved without differences. No adverse event and minimum discomfort were reported.

CONCLUSIONS

The non-ablative CO2 laser is a safe and effective treatment of VVA and has positive effects on sexual function in BCS regardless the use of adjuvant therapies and the initial grade of VVA.

Randomized trial: treatment of genitourinary syndrome of menopause using radiofrequency

OBJECTIVE

A randomized controlled study was conducted to evaluate the safety and efficacy of radiofrequency treatment in postmenopausal women not willing to use or presenting a contraindication for menopause hormone therapy (MHT) and suffering from genitourinary syndrome of menopause (GSM).

METHODS

A prospective randomized open study evaluated the effect of radiofrequency treatment versus a gel (control group) in postmenopausal women suffering from GSM. Patients were assessed at baseline and after 10-12 weeks of treatment for severity of vulvovaginal atrophy, dyspareunia, pH, vaginal smear maturation index, Vaginal Health Index and Female Sexual Function Index. The difference at baseline and after 10-12 weeks of treatment and the difference in improvement were tested between groups by a two-sample t-test and the Mann-Whitney test.

RESULTS

Due to the COVID-19 pandemic, we were only able to treat 48 patients (24 patients using radiofrequency and 24 patients using a gel). Globally, at the end of the study, there were no differences in changes of the measured outcomes between the group of women treated with radiofrequency and the control group.

CONCLUSION

Radiofrequency treatment was found to be safe, but was not superior to a gel, although the study lacked power. The study was registered at ClinicalTrials.gov (NCT03857893).

Sexual Dysfunction and Dyspareunia in the Setting of the Genitourinary Syndrome of Menopause

Sexual dysfunction is a common consequence of the genitourinary syndrome of menopause (GSM). In this book chapter, we discuss the pathophysiology, prevalence, evaluation, and evidence-based management of sexual dysfunction in patients affected by GSM. Additionally, we present an algorithm to guide clinicians in the management and treatment of sexual dysfunction in this setting based on available evidence and best practices.

Vaginal erbium laser treatment for stress urinary incontinence: A multicenter randomized sham-controlled clinical trial

OBJECTIVE

To evaluate the efficacy and safety of non-ablative vaginal Er:YAG laser device in stress urinary incontinence (SUI) treatment.

METHODS

We conducted a multicenter blinded randomized sham-controlled trial in which women with urodynamic SUI were randomization to active arm using Er:YAG laser therapy, and sham arm using sham handpiece. Patients received two treatments 1 month apart. The primary outcomes measure was 1 h pad weight test measured at 6 months. Secondary outcomes were durability of treatment success at 12 months, and questionnaires for assessment of SUI severity (ICIQ-UI SF), sexual function (PISQ-12) and HRQoL (KHQ), and incidence and severity of device related adverse events and pain (VAS).

RESULTS

A total of 110 participants with SUI were recruited; 73 in the active arm and 37 in the sham arm. Two participants were excluded; one was assigned the wrong treatment and one withdrew their consent. Treatment success was observed in 36% of the sham arm and 59% of the active arm; in the latter, odds of achieving treatment success were more than three-fold higher (OR 3.63, 95% CI: 1.3-11.2, P = 0.02). HRQoL by KHQ showed significant improvement in the active versus the sham arm (OR 0.36, 95% CI: 0.15-0.87, P = 0.003). Similarly, subjective patient assessment of general and sexual function improvement with PISQ-12 and PGI-I showed superior effect over sham (OR 2.8, 95% CI: 1.2-7.0, P = 0.02 and OR 0.13, 95% CI: 0.05-0.36, P < 0.001, respectively).

CONCLUSION

Non-ablative vaginal Er:YAG laser therapy significantly improves SUI symptoms versus sham treatment. Er:YAG laser therapy should be considered as a non-surgical treatment option for SUI patients.

Fractional CO2 laser for genitourinary syndrome of menopause: evaluating the evidence

The fractionated CO2 laser has been marketed to women for a variety of gynecologic symptoms and conditions, including the genitourinary syndrome of menopause (GSM). The evidence has been limited, precluding conclusions regarding the efficacy and safety of the therapy. However, data from randomized, controlled trials evaluating this technology for GSM are now available. This Practice Pearl addresses the latest data concerning the use of the fractionated CO2 laser for the treatment of GSM.

Clinical Practice Guidelines for Managing Genitourinary Symptoms Associated With Menopause

Genitourinary syndrome of menopause encompasses the group of urogenital signs and symptoms resultant from hypoestrogenism, including genital dryness, burning or irritation, sexual discomfort, pain or dysfunction, and urinary urgency, dysuria, and recurrent urinary tract infections. Genitourinary syndrome of menopause can have a profound impact on well-being, functioning, and quality of life in postmenopausal women. Treatment includes vaginal moisturizers and lubricants geared towards providing symptomatic relief; hormonal treatments which promote epithelial thickening and production of vaginal secretions; and pelvic floor physical therapy along with behavioral therapies that address pelvic floor hypertonicity and psychosocial factors.

Carbon dioxide laser therapy for the management of genitourinary syndrome of menopause: A meta‑analysis of randomized controlled trials

Genitourinary symptoms of menopause (GSM) affect ~50% of women after menopause. Recently, CO2 laser therapy has been used for managing GSM but without high quality evidence. The present review assessed the effectiveness of CO2 laser therapy in the management of GSM. PubMed, Embase, Web of Science, CENTRAL and Scopus databases were searched for randomized controlled trials (RCTs), published up to June 30, 2023, comparing CO2 laser and sham laser treatments for GSM management. The outcomes of interest included Female Sexual Function Index (FSFI), Vaginal Health Index (VHI) and visual analog scale (VAS) for dyspareunia, dryness, burning, itching and dysuria. A total of seven RCTs were included in the review and meta-analysis, with 6/7 studies using three sessions of laser therapy, 4-8 weeks apart. Meta-analysis demonstrated no statistically significant difference in FSFI [mean difference (MD), -1.48; 95% CI, -5.85, 2.89; I2=45%] and VHI scores (MD, -0.18; 95% CI, -1.66, 1.31; I2 =72%) between laser and control groups. Meta-analysis also demonstrated no statistically significant difference in VAS scores for dyspareunia (MD, -1.63; 95% CI; -4.06, 0.80; I2=91%), dryness (MD, -1.30; 95% CI, -3.14, 0.53; I2=75%), burning (MD, -0.76; 95% CI, -2.03; 0.51 I2=56%), itching (MD, -0.28; 95% CI, -0.95, 0.38; I2=0%) and dysuria (MD, 0.15; 95% CI, -0.37, 0.67; I2=23%) between the groups. The included RCTs had low risk of bias. In conclusion, meta-analyses of high-quality sham-controlled RCTs indicated that CO2 may not have any beneficial effect on GSM. Limited data and high heterogeneity in meta-analyses in this area of research are important limitations that need to be addressed by future RCTs.

CO2 Laser versus Sham Control for the Management of Genitourinary Syndrome of Menopause: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

In the context of the menopausal transition, genitourinary syndrome of menopause (GSM) refers to a range of genitourinary symptoms, from vaginal dryness to dysuria and urinary urgency. While hormonal treatments are standard, their associated side effects have driven the exploration of alternatives like vaginal CO2 laser. We aimed to evaluate the randomized controlled trials (RCTs) comparing vaginal CO2 laser treatment for GSM to sham controls. This systematic review sourced four electronic databases until June 2023. The analysis incorporated seven RCTs with 407 women. The CO2 laser and sham control were comparable for most parameters, including the female sexual function index (FSFI) and visual analogue scale (VAS) for dyspareunia, vaginal health index, pH, and patient satisfaction. However, the CO2 laser group showed significant improvement in the vaginal assessment scale for GSM symptoms. Sensitivity analyses revealed that parameters like FSFI showed significant differences in favor of CO2 laser group upon the exclusion of specific studies. In conclusion, vaginal CO2 laser therapy emerges as a promising alternative for GSM management, especially for most bothersome GSM symptoms; however, the need for further well-designed RCTs remains to validate its broad safety and efficacy.

Vaginal Laser Treatment for the Genitourinary Syndrome of Menopause in Breast Cancer Survivors: A Narrative Review

Vulvovaginal atrophy (VVA) is a chronic condition resulting from reduced estrogen levels during menopause. The North American Menopause Society and the International Society for the Study of Women's Sexual Health suggested the term "genitourinary syndrome of menopause" (GSM) to indicate the broader aspects of VVA. Breast cancer treatments, such as chemotherapy and endocrine therapy, can induce early and abrupt menopausal symptoms, including GSM, which negatively affects sexual function and the quality of life of the survivors. Vaginal laser therapy has emerged as a safe and effective option for the management of GSM in breast cancer survivors (BCSs). Two main types of lasers, the non-ablative erbium:YAG laser and fractional microablative CO2 vaginal laser, have been evaluated for GSM treatment. While there are few randomized controlled trials (RCTs) on the subject of BCSs, a wealth of prospective and retrospective studies have highlighted the beneficial effects of vaginal laser therapy on the symptoms of VVA, vaginal health, sexual function, and overall quality of life. More comprehensive research is essential to confirm its enduring effectiveness and safety, with a focus on conducting standardized and meticulously controlled investigations. This study is a narrative review that summarizes clinical trials ranging from the earliest to the most recent ones on laser treatment for GSM in BCSs.

Efficacy and safety of carbon dioxide laser therapy compared with sham for genitourinary syndrome of menopause management: a meta-analysis of randomized clinical trials

IMPORTANCE

Data on whether the carbon dioxide (CO 2 ) laser is useful for treatment of genitourinary syndrome of menopause (GSM) are inconsistent.

OBJECTIVE

This meta-analysis evaluated the benefits and safety of CO 2 laser compared with sham treatment of GSM.

EVIDENCE REVIEW

A relevant literature search of Europe PMC, MEDLINE, Scopus, and ClinicalTrials.gov databases using specific keywords was conducted. The results of continuous variables were pooled into the standardized mean difference (SMD), whereas dichotomous variables were pooled into odds ratio with 95% confidence intervals (95% CI) using random-effects models. A funnel plot was used to assess for the presence of publication bias.

FINDINGS

A total of six randomized clinical trials were included. Pooled analysis revealed that CO 2 laser therapy was associated with a higher reduction in the Vaginal Assessment Scale (SMD, -0.81 [95% CI, -1.59 to -0.04]; P = 0.04; I2 = 88%) and Urinary Distress Inventory short form (SMD, -0.45 [95% CI, -0.84 to -0.06]; P = 0.02; I2 = 0%), and greater patient satisfaction rate (odds ratio, 5.46 [95% CI, 2.23 to 13.37]; P = 0.0002; I2 = 0%) when compared with sham-only treatment. Meanwhile, the Female Sexual Function Index, Vaginal Health Index, and Patient Global Impression Improvement did not differ significantly between groups. Adverse events were only mild with no serious adverse events reported.

CONCLUSIONS AND RELEVANCE

CO 2 laser therapy may improve the overall treatment of GSM with a relatively good safety profile. However, further randomized clinical trials with larger sample sizes are still needed to confirm the results of this study.

Nonestrogen Therapies for Treatment of Genitourinary Syndrome of Menopause: A Systematic Review

OBJECTIVE

To systematically review the literature and provide clinical practice guidelines regarding various nonestrogen therapies for treatment of genitourinary syndrome of menopause (GSM).

DATA SOURCES

MEDLINE, EMBASE, ClinicalTrials.gov , and Cochrane databases were searched from inception to July 2021. We included comparative and noncomparative studies. Interventions and comparators were limited to seven products that are commercially available and currently in use (vaginal dehydroepiandrosterone [DHEA], ospemifene, laser or energy-based therapies, polycarbophil-based vaginal moisturizer, Tibolone, vaginal hyaluronic acid, testosterone). Topical estrogen, placebo, other nonestrogen products, as well as no treatment were considered as comparators.

METHODS OF STUDY SELECTION

We double-screened 9,131 abstracts and identified 136 studies that met our criteria. Studies were assessed for quality and strength of evidence by the systematic review group.

TABULATION, INTEGRATION, AND RESULTS

Information regarding the participants, details on the intervention and comparator and outcomes were extracted from the eligible studies. Alternative therapies were similar or superior to estrogen or placebo with minimal increase in adverse events. Dose response was noted with vaginal DHEA and testosterone. Vaginal DHEA, ospemifene, erbium and fractional carbon dioxide (CO 2 ) laser, polycarbophil-based vaginal moisturizer, tibolone, hyaluronic acid, and testosterone all improved subjective and objective signs of atrophy. Vaginal DHEA, ospemifene, tibolone, fractional CO 2 laser, polycarbophil-based vaginal moisturizer, and testosterone improved sexual function.

CONCLUSION

Most nonestrogen therapies are effective treatments for the various symptoms of GSM. There are insufficient data to compare nonestrogen options to each other.

Applicability of vaginal energy-based devices in urogynecology: evidence and controversy

OBJECTIVE

This study aimed to analyze the evidence and controversies about the use of vaginal energy-based devices (laser and radiofrequency) for treatment of genitourinary syndrome of menopause, recurrent urinary tract infection, urinary incontinence, and genital prolapse through a literature review.

METHODS

A search of literature databases (PubMed, Medline) was performed for publications in December 2022. Keywords included genitourinary syndrome of menopause, vaginal laxity, vaginal/vulvovaginal atrophy, urinary tract infection, urgency incontinence, frequency, urgency, stress urinary incontinence, genital prolapses AND energy-based devices, AND vaginal laser, AND vaginal radiofrequency, AND CO2 laser, AND Er:YAG laser. Publications in English from the last 7 years were reviewed and selected by the authors.

RESULTS

The literature regarding vaginal energy-based devices in the treatment of urogynecological conditions is primarily limited to prospective case series with small numbers and short-term follow-up. Most of these studies showed favorable results, improvement of symptoms with low risk, or no mention of serious adverse events. Consensus statement documents from major medical societies suggest caution in recommending these therapies in clinical practice until more relevant data from well-designed studies become available.

CONCLUSION

The potential of the vaginal laser and radiofrequency as a therapeutic arsenal for the evaluated urogynecological conditions is great, but qualified research must be done to prove their efficacy and long-term safety, define application protocols, and recommend the use of these technologies in clinical practice.

The yin and yang of GSM and low sexual desire

Numerous surveys have documented that sexuality and/or sexual activity is important to women at all stages of adulthood, including postmenopause. Genitourinary syndrome of menopause (GSM) and hypoactive sexual desire disorder (HSDD) are common disorders in postmenopausal women and may co-occur. Both are often undiagnosed due to a lack of knowledge of the disorder, health-care professional discomfort in discussing sexual problems or a lack of routine screening. It is incumbent upon health-care professionals to identify and differentiate these conditions in women through a biopsychosocial assessment, and may require a focused physical examination. Numerous treatments, both non-pharmacologic and pharmacologic, are available to address GSM and HSDD.

Vaginal laser therapy for GSM/VVA: where we stand now - a review by the EUGA Working Group on Laser

Vulvovaginal atrophy (VVA) is a chronic progressive condition that involves the genital and lower urinary tracts, related to the decrease of serum estrogenic levels when menopause occurs. The definition of genitourinary syndrome of menopause (GSM) is a medically more accurate, all-encompassing and publicly acceptable term than VVA. Due to the chronic progressive trend of GSM, symptoms tend to reappear after the cessation of therapy, and frequently long-term treatment is required. First-line therapies include vulvar and vaginal lubricant or moisturizers, and, in the case of failure, low-dose vaginal estrogens are the preferred pharmacological therapy. Populations of patients, such as breast cancer (BC) survivors, are affected by iatrogenic GSM symptoms with concerns about the use of hormonal therapies. The non-ablative erbium:YAG laser and the fractional microablative CO2 vaginal laser are the two main lasers evaluated for GSM treatment. The aim of this comprehensive review is to report the efficacy and safety of Er:YAG and CO2 vaginal lasers for GSM treatment. Vaginal laser therapy has been demonstrated to be effective in restoring vaginal health, improving VVA symptoms and sexual function. The data suggest that both Er:YAG and CO2 vaginal lasers are safe energy-based therapeutic options for management of VVA and/or GSM symptoms in postmenopausal women and BC survivors.

The efficacy of CO2 laser in the treatment of genitourinary syndrome of menopause: a systematic review and meta-analysis of randomized controlled trials

CO₂ laser has been proposed as a treatment strategy for genitourinary syndrome of menopause (GSM). In order to assess its efficacy for treating GSM, we conducted a systematic review and meta-analysis. To identify the current state of randomized controlled trials on CO₂ laser therapy for GSM, a literature review was conducted. We systematically searched the following databases: PUBMED, EMBASE and the Cochrane Controlled Trials Register. In addition, a review of the references in the retrieved studies was carried out. Of 562 identified studies, 9 were eligible and were included in our analysis, involving 523 patients in total. Based on our analysis, CO₂ laser has no statistical difference compared with estrogen in VHI (p = 0.87), FSFI total score (p = 0.19), FSFI-Arousal (p = 0.11), FSFI-Desire (p = 0.72), FSFI-Orgasm (p = 0.45) and FSFI-Satisfaction (p = 0.08). The meta-analysis also showed that CO₂ laser significantly improved FSFI-Lubrication scores compared with estrogen therapy (p = 0.0004). Furthermore, compared with the sham group, CO₂ laser group had statistically improved VHI scores (p = 0.003) and FSFI scores (p < 0.00001). CO₂ laser therapy may be an effective alternative to estrogen therapy for GSM both in cases where estrogen is not applicable because of comorbidities and in cases in which women do not desire to take estrogen.

Diagnosis, causes, and treatment of dyspareunia in postmenopausal women

IMPORTANCE AND OBJECTIVES

Evaluation and treatment of dyspareunia remains a significant unmet need despite the availability of safe and effective treatments. The objectives of this review are to consider evaluation techniques, the medical causes, and treatment options for dyspareunia in postmenopausal women.

METHODS

This narrative review used PubMed to search for English-language articles related to postmenopausal dyspareunia. Search terms included, but were not limited to, dyspareunia, genitourinary syndrome of menopause, sexual dysfunction, postmenopausal dyspareunia, posthysterectomy dyspareunia, and postcancer dyspareunia.

FINDINGS

Many postmenopausal women with dyspareunia do not discuss their symptoms with their physicians. Healthcare clinicians should broach the topic of dyspareunia with their patients using oral or written questionnaires. In addition to a thorough medical history and physical examination, various tools can be used as further assessments, including vaginal pH, vaginal dilators, imaging, vulvar biopsy, vulvoscopy and photography, the cotton swab test, sexually transmitted infection screening, and vaginitis testing. Although dyspareunia in postmenopausal women is often due to the genitourinary syndrome of menopause, other conditions can also cause dyspareunia, including hypertonic pelvic floor, hysterectomy, cancer treatment, lichen conditions, vulvar cancer, vestibulodynia, and pelvic organ prolapse. Some of the treatments discussed include lubricants, moisturizers, vaginal estrogen, ospemifene, dehydroepiandrosterone, local testosterone therapy, cannabidiol, and fractional CO2 laser treatments. In some cases, dyspareunia may need to be specifically addressed by pelvic floor physical or sex therapists.

CONCLUSIONS

Dyspareunia is a common issue in postmenopausal women, which remains largely untreated. Women with dyspareunia require a thorough history, targeted physical examination, and coordination of multiple disciplines including medical clinicians, pelvic floor physical therapists, and sex therapists.

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.

Effect of Fractional Carbon Dioxide vs Sham Laser on Sexual Function in Survivors of Breast Cancer Receiving Aromatase Inhibitors for Genitourinary Syndrome of Menopause: The LIGHT Randomized Clinical Trial

IMPORTANCE

Survivors of breast cancer present more severe symptoms of genitourinary syndrome of menopause (GSM) than patients without history of breast cancer. Recently, new treatments, such as vaginal laser therapy, have appeared, but evidence of their efficacy remains scarce.

OBJECTIVE

To assess the safety and efficacy of carbon dioxide (CO2) vs sham vaginal laser therapy after 6 months of follow-up in survivors of breast cancer with GSM receiving aromatase inhibitors.

DESIGN, SETTING, AND PARTICIPANTS

This prospective double-blind sham-controlled randomized clinical trial with two parallel study groups was performed during October 2020 to March 2022 in a tertiary referral hospital. Survivors of breast cancer using aromatase inhibitors were assessed for eligibility, and eligible patients were randomized into the 2 treatment groups. Follow-up was conducted at 6 months. Data were analyzed in July 2022.

INTERVENTIONS

All patients from both groups were instructed to use the first-line treatment (FLT) based on nonhormonal moisturizers and vaginal vibrator stimulation. Patients for each group were allocated to 5 monthly sessions of fractional CO2 laser therapy (CLT) or sham laser therapy (SLT).

MAIN OUTCOMES AND MEASURES

The primary outcome was sexual function, evaluated through Female Sexual Function Index (FSFI) score. Other subjective measures of efficacy included a visual analog scale of dyspareunia, vaginal pH, a Vaginal Health Index, quality of life (assessed via Short-Form 12), and body image (assessed with the Spanish Body Image Scale). Objective measures of efficacy included vaginal maturation index, vaginal epithelial elasticity (measured in Pascals) and vaginal epithelial thickness (measured in millimeters). Measures were assessed before and after the intervention. Tolerance (measured on a Likert scale), adverse effects, and estradiol levels were recorded.

RESULTS

Among 211 survivors of breast cancer assessed, 84 women were deemed eligible and 72 women (mean [SD] age, 52.6 [8.3] years) were randomized to CLT (35 participants) or SLT (37 participants) and analyzed. There were no statistically significant differences between groups at baseline. At 6 months, both groups showed improvement in FSFI (mean [SD] score at baseline vs 6 months: CLT, 14.8 [8.8] points vs 20.0 [9.5] points; SLT, 15.6 [7.0] points vs 23.5 [6.5] points), but there was no significant difference between CLT and SLT groups in the improvement of sexual function evaluated through the FSFI test overall (mean [SD] difference, 5.2 [1.5] points vs 7.9 [1.2] points; P = .15) or after excluding women who were not sexually active (mean [SD] difference, 2.9 [1.4] points vs 5.5 [1.1] points; P = .15). There were also no differences between improvement of the 2 groups at 6 months of follow-up in the other assessed subjective outcomes, including dyspareunia (mean [SD] difference, -4.3 [3.4] vs -4.5 [2.3]; P = .73), Vaginal Health Index (mean [SD] difference, 3.3 [4.1] vs 5.0 [4.5]; P = .17), body image (mean [SD] difference, -3.7 [4.5] vs -2.7 [4.8]; P = .35), and quality of life (mean [SD] difference, -0.3 [3.6] vs -0.7 [3.2]; P = .39). Similarly, there were no differences in improvements in objective outcomes, including vaginal pH (mean [SD] difference, -0.6 [0.9] vs -0.8 [1.2]; P = .29), vaginal maturation index (mean [SD] difference, 10.2 [17.4] vs 14.4 [17.1]; P = .15), vaginal epithelial thickness (mean [SD] difference, 0.021 [0.014] mm vs 0.013 [0.012] mm; P = .30), vaginal epithelial elasticity (mean [SD] difference, -1373 [3197] Pascals vs -2103 [3771] Pascals; P = .64). There were significant improvements in the overall analysis regardless of group in many outcomes. The 2 interventions were well tolerated, but tolerance was significantly lower in the CLT group than the SLT group (mean [SD] Likert scale score, 3.3 [1.3] vs 4.1 [1.0]; P = .007). No differences were observed in complications or serum estradiol levels.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, vaginal laser treatment was found to be safe after 6 months of follow-up, but no statistically significant differences in efficacy were observed between CLT and SLT.

Clinical Consensus Statement: Vaginal Energy-Based Devices

ABSTRACT

This clinical consensus statement on vaginal energy-based devices (EBDs) reflects an update by content experts from the American Urogynecologic Society's EBD writing group. In 2019, the American Urogynecologic Society's EBD writing group used a modified Delphi process to assess statements that were evaluated for consensus after a structured literature search. A total of 40 statements were assessed and divided into 5 categories: (1) patient criteria, (2) health care provider criteria, (3) efficacy, (4) safety, and (5) treatment considerations. Of the 40 statements that were assessed, 28 reached consensus and the remaining 12 did not. Lack of evidence was among the main reasons that vulvovaginal EBD treatment statements did not reach consensus. In March 2022, these statements were reassessed using the interim literature.

Laser treatment for genitourinary syndrome of menopause: Scientific Impact Paper No. 72 (July 2022): Scientific Impact Paper No. 72 (July 2022)

Genitourinary syndrome of menopause (GSM) is the term used to describe the group of symptoms including vaginal pain, vaginal dryness, itching, pain during sexual intercourse and fragile vaginal tissues as well as urinary symptoms including urinary frequency, urgency, incontinence, blood in the urine (haematuria) and recurrent urinary tract infections that occur due to a lack of the hormone estrogen. These symptoms can have a significant negative impact on psychosexual issues, sexual function and quality of life in postmenopausal women. Traditionally women have been treated with vaginal lubricants, vaginal moisturisers or low-dose vaginal estrogens. Lasers have been used in the cosmetic industry for collagen remodelling and repair of the skin. Therefore, it has been suggested that laser therapy may be used on the vagina as an alternative treatment for GSM. A review of all the published studies assessing the safety and efficacy of laser therapy for GSM have shown promising beneficial results. The majority of studies to date have been small, short-term, observational studies. However, there are randomised controlled trials underway. Laser treatment may be beneficial for the symptoms of GSM but until more robust evidence is available it should not be adopted into widespread practice, and should be used as part of a research study only.

The evidence behind the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus: A state-of-the-art review

In recent years, LASER has been introduced as a minimally invasive treatment for a broad range of vaginal and vulvar symptoms and diseases. However, the efficacy and safety of vaginal and vulvar LASER has continuously been questioned. The aim of this study is to create an overview of the current literature and discuss the controversies within the use of LASER for genitourinary syndrome of menopause, vulvovaginal atrophy, urinary incontinence and lichen sclerosus. A search string was built in PubMed. The search was commenced on August 25, 2021 and closed on October 27, 2021. Two authors screened the studies in Covidence for inclusion according to the eligibility criteria in the protocol. The data were extracted from the studies and are reported in both text and tables. This review included 114 papers, of which 15 were randomized controlled trials (RCTs). The effect of LASER as a vaginal treatment was investigated for genitourinary syndrome of menopause in 36 studies (six RCTs), vulvovaginal atrophy in 34 studies (four RCTs) and urinary incontinence in 30 studies (two RCTs). Ten studies (three RCTs) investigated the effect of vulvar treatment for lichen sclerosus. Half of the included RCTs, irrespective of indication, did not find a significant difference in improvement in women treated with vaginal CO₂ or Er:YAG LASER compared with their respective controls. However, most non-comparative studies reported significant improvement after exposure to vaginal or vulvar LASER across all indications. Included studies generally had a short follow-up period and only a single RCT followed their participants for more than 6 months post treatment. Adverse events were reported as mild and transient and 99 studies including 51 094 patients provided information of no serious adverse events. In conclusion, this review found that the effect of vaginal and vulvar LASER decreases with higher study quality where potential biases have been eliminated. We therefore stress that all patients who are treated with vaginal or vulvar LASER should be carefully monitored and that LASER for those indications as a treatment should be kept on a research level until further high-quality evidence is available.

Short-Term Efficacy and Safety of Non-Ablative Laser Treatment Alone or with Estriol or Moisturizers in Postmenopausal Women with Vulvovaginal Atrophy

BACKGROUND

Among treatments for vulvo-vaginal atrophy (VVA), there is a new kind of energy-based device, the non-ablative CO2 laser.

AIM

This study aimed to assess the efficacy and safety of the non-ablative CO2 laser in menopausal women with VVA as a monotherapy or in association with vaginal estriol or moisturizer.

METHODS

Seventy-five women with VVA received laser treatment (Laser group), laser plus estriol gel (Laser+E) or laser plus moisturizers (Laser+M). The study protocol consisted of 3 monthly laser sessions (t0, t1, t2) and a gynecological examination at baseline and 1 month after last laser treatment (t3). Objective measures included VHI (Vaginal Health Index) and VuHI (Vulvar Health Index); subjective symptoms of VVA (Dryness, Burning, Itching, Dysuria) evaluated via visual analog scales, sexual function evaluated by FSFI (Female Sexual Function Index), FSDS (Female Sexual Distress Score) and MENQOL (Mopause-specific Quality Of Life). Adverse events and discomfort encountered during the procedure were also assessed.

OUTCOMES

Primary outcomes were the evaluation of VHI and VuHI and secondary outcomes were changes in VVA symptoms (VAS), sexual function (MENQOL, FSFI, FSDS) and discomfort during the procedure.

RESULTS

Seventy-five women (25 in Laser, 25 in Laser+E and 25 in Laser+M group) completed the study. At t3, mean VHI, VuHI, dryness, burning and itching VAS scores improved significantly with no differences between the groups. The lubrication domain of FSFI improved significantly only in the Laser+M group, while the pain domain improved significantly in all women with no differences between the groups. FSFI and FSDS overall scores and MENQOL sexual domain improved in all women with no significant difference between the groups. The mean score of the pain during the procedure was low at t0 and did not change throughout the study.

CLINICAL IMPLICATIONS

This study extends knowledge concerning the effectiveness of a new non-ablative CO2 laser in post-menopausal women with VVA.

STRENGTHS & LIMITATIONS

This is one of the first studies on this kind of laser and is the first to compare the effectiveness of laser treatment alone or in combination with vaginal estriol or moisturizers. Parameters of VVA and sexual function were evaluated using validated tools. Study limitations include short follow-up time, the limited number of participants and the absence of a sham-controlled group.

CONCLUSION

Non-ablative CO2 laser seems to be an effective treatment for VVA in menopausal women. Our preliminary data shows that it can be effective as monotherapy or with adjuvant treatments.

Vulvovaginal atrophy management with a laser: the placebo effect or the conditioning Pavlov reflex

Postmenopausal vulvovaginal pain and atrophy require appropriate and sensitive outcomes that correlate with the genital discomfort, symptoms and expected changes. In some studies, hormone and laser treatments do not detect benefits due to the fact that appropriate measuring tools were not used. While some studies have demonstrated placebo effects for both therapeutic approaches, others support that sham-intervention could be a therapeutic by creating a conditioning reflex. However, obtained results are directly related with the quality of outcomes: you get what you measure. It is imperative to follow the Core Outcomes in Menopause global initiative.

Long-Term Follow-Up of Fractional CO2 Laser Therapy for Genitourinary Syndrome of Menopause in Breast Cancer Survivors

(1) Background: The objective of this study was to determine the long-term efficacy of fractional CO₂ laser therapy in breast cancer survivors. (2) Methods: This was a single-arm study of breast cancer survivors. Participants received three treatments of fractional CO₂ laser therapy and returned for a 4 week follow-up. Participants were contacted for follow-up at annual intervals. The Vaginal Assessment Scale (VAS), the Female Sexual Function Index (FSFI), the Female Sexual Distress Scare Revised (FSDS-R), the Urinary Distress Inventory (UDI), and adverse events were collected and reported for the two-year follow-up. The changes in scores were compared between the four-week and two-year and the one-year and two-year follow-ups using paired t-tests. (3) Results: In total, 67 BC survivors were enrolled, 59 completed treatments and the four week follow-up, 39 participated in the one-year follow-up, and 33 participated in the two-year follow-up. After initial improvement in the VAS from baseline to the four week follow-up, there was no statistically significant difference in the VAS score (mean Δ 0.23; 95% CI [−0.05, 0.51], p = 0.150) between the four week follow-up and the two-year follow-up. At the two-year follow-up, the FSFI and FSDS-R scores remained improved from baseline and there was no statistically significant change in the FSFI score (mean Δ −0.83; 95% CI [−3.07, 2.38] p = 0.794) or the FSDS-R score (mean Δ −2.85; 95% CI [−1.88, 7.59] p = 0.227) from the one to two-year follow-up. The UDI scores approached baseline at the two-year follow-up; however, the change between the one- and two-year follow-ups was not statistically significant (mean Δ 4.76; 95% CI [−1.89, 11.41], p = 0.15). (4) Conclusions: Breast cancer survivors treated with fractional CO₂ laser therapy have sustained improvement in sexual function two years after treatment completion, suggesting potential long-term benefit.

Treatment of Vulvovaginal Atrophy with Fractional CO2 Laser: Evaluating Real-World Data

Objective: We aimed to evaluate real-world data for the use of fractional CO₂ laser therapy for treating symptoms of vulvovaginal atrophy (VVA). Background: VVA is widespread and can reduce the patients' quality of life. There is a lack of data regarding its therapy with laser, especially for daily practice (i.e., real-world data). Methods: Thirty-six patients were treated in a single medical center. They consisted of pre- and postmenopausal women and received three fractional CO₂ laser therapy treatments with 3-6 weeks between each treatment. Each patient financed the treatment privately. The symptoms pain, pruritus, dyspareunia, burning, dryness, and dysuria were recorded with a visual analog scale (1-10) before the first, second, and third laser treatment. The data were examined retrospectively. Results: Pain was reduced from a mean of 2.5 points (minimum 0, maximum 9 points) to 1.1 (minimum 0, maximum 8 points) before the third laser treatment. Pruritus showed a mean score of 3.8 (minimum 0, maximum 10 points). This decreased to 1.4 (minimum 0, maximum 8 points). Dyspareunia scored a mean of 6.8 (minimum 0, maximum 10 points). After two laser therapies, the score was 3.3 (minimum 0, maximum 8 points). Burning showed 4.2 points (minimum 0, maximum 10 points). Having experienced two laser therapy sessions, the patients scored 1.5 (minimum 0, maximum 9 points) points. The severity of dryness dropped from 6.5 (minimum 0, maximum 10 points) to 3.3 (minimum 0, maximum 9 points). Dysuria was stated with 1.8 points (minimum 0, maximum 10 points) before the first and 0.5 points (minimum 0, maximum 6 points) before the third laser therapy. All changes showed statistical significance (p < 0.002). Conclusions: This real-world data propose fractional CO₂ laser to reduce VVA-associated genital discomfort, thus being a valuable therapy option for pre- and postmenopausal women.

Vaginal CO2 laser therapy versus sham for genitourinary syndrome of menopause management: a systematic review and meta-analysis of randomized controlled trials

IMPORTANCE

The research of new therapeutic modalities, especially with energy-based devices, has been increasing nowadays for genitourinary syndrome of menopause (GSM) management. Microablative fractional CO2 laser has been used for pelvic floor dysfunction management.

OBJECTIVE

To conduct a systematic review and meta-analysis of randomized controlled trials to compare fractional CO2 laser therapy versus sham therapy for GSM management.

EVIDENCE REVIEW

We searched for the available randomized clinical trials in Cochrane Library, PubMed, ISI web of science, and Scopus during March 2021. We included randomized clinical trials that compared CO2 laser to sham among postmenopausal women with GSM diagnosis. We extracted the available data from included studies and pooled them in a meta-analysis model using RevMan software. Our main outcomes were total vaginal score assessment using the Vaginal Assessment Scale, sexual function using the Female Sexual Function Index, urinary symptoms using the Urogenital Distress Inventory-6, and satisfaction.

FINDINGS

Three studies met our inclusion criteria with a total number of 164 women. The CO2 laser was linked to a significant reduction in Vaginal Assessment Scale score when compared with the sham group (mean difference [MD] = -0.49, 95% CI [-0.75 to -0.22], P = 0.004). The CO2 laser was associated with a significant improvement in Female Sexual Function Index score in comparison with sham group (MD = 9.37, 95% CI [6.59-12.14], P < 0.001). In addition, a significant reduction in Urogenital Distress Inventory-6 score was reported among the CO2 laser group (MD = -6.95, 95% CI [-13.24 to -0.67], P = 0.03). More women were significantly satisfied among the CO2 laser group (risk ratio  = 1.98, 95% CI [1.36-2.89], P = 0.004).

CONCLUSIONS AND RELEVANCE

CO2 laser therapy is a promising alternative for GSM management. Further randomized trials with larger sample sizes are required to confirm our findings.

Management of postmenopausal vulvovaginal atrophy: recommendations of the International Society for the Study of Vulvovaginal Disease

OBJECTIVE

To develop a best practice document for the management of postmenopausal vulvovaginal atrophy (VVA).

METHOD

Literature review carried out using clinical terms, treatments or interventions and comorbidity related to VVA.

RESULTS

There is a wide variety of interventions that may produce temporal benefits for VVA. However, there are significant limitations in scientific publications concerning VVA and related issues, including variable outcome evaluations, variability in population age range, and small, often underpowered sample sizes. Therapeutic management of VVA should follow a sequential order, considering women's age, symptoms, general health as well as treatment preference. Beneficial options include lubricants, moisturizers, vaginal estrogens (estradiol, estriol, promestriene, conjugated estrogens), androgens, prasterone, and laser application. In women with general menopausal symptoms who are candidates for systemic hormone therapy, the lowest effective dose should be used. Oral ospemifene is an effective selective estrogen receptor modulator to treat VVA. Systemic androgens have a limited role. Although laser procedures are commonly used, at this moment the International Society for the Study of Vulvovaginal Disease does not endorse its use out of the setting of clinical trials. Pelvic floor muscle training improves blood flow and elasticity of the vulvovaginal tissue. In breast cancer survivors, moisturizers and lubricants are first line therapy. However, limited absorption of low/ultra-low doses of estrogens suggests safety, especially in women under treatment with aromatase inhibitors. As clinical practice and available preparations vary between countries this text should be adapted to local circumstances.

CONCLUSIONS

There is a wide range of therapeutic options to individualize VVA treatments.

Carbon Dioxide Laser Vulvovaginal Rejuvenation: A Systematic Review

Genitourinary syndrome of menopause (GSM) causes significant symptomatic aggravation that affects the quality of life (QoL). Vulvovaginal atrophy (VVA), the hallmark of GSM, is managed with topical non-hormonal therapy, including moisturizers and lubricants, and topical estrogen application. Patients not responding/being unsatisfied with previous local estrogen therapies are candidates for a noninvasive modality. Carbon dioxide (CO2) laser therapy, especially the fractionated type (FrCO2), has drawn considerable attention over the past two decades as a non-invasive treatment for GSM. This systematic review describes the accumulated evidence from 40 FrCO2 laser studies (3466 participants) in GSM/VVA. MEDLINE, Scopus and Cochrane databases were searched through April 2021. We analyze the effects of FrCO2 laser therapy on symptoms, sexual function, and QoL of patients with GSM/VVA. As shown in this review, FrCO2 laser therapy for GSM shows good efficacy and safety. This modality has the potential to advance female sexual wellness. Patient satisfaction was high in the studies included in this systematic review. However, there is a lack of level I evidence, and more randomized sham-controlled trials are required. Furthermore, several clinical questions, such as the number of sessions required that determine cost-effectiveness, should be addressed. Also, whether FrCO2 laser therapy may exert a synergistic effect with systemic and/or local hormonal/non-hormonal treatments, energy-based devices, and other modalities to treat GMS requires further investigation. Lastly, studies are required to compare FrCO2 laser therapy with other energy-based devices such as erbium:YAG laser and radiofrequency.

Vaginal laser therapy for genitourinary syndrome of menopause - systematic review

BACKGROUND

Genitourinary syndrome of menopause (GSM) can have a great impact on the quality of life (QOL), and affects between 53.8% and 90% of postmenopausal women. The literature suggests that vaginal laser therapy could be an effective treatment for GSM symptoms, but its efficacy and safety have not been established and international societies do not endorse its use. Despite that, there has been an increase in the use of vaginal laser therapy globally over the last decade.

OBJECTIVE

The objective of this review is to evaluate the literature which assesses the efficacy and safety of the vaginal laser therapy in the treatment of GSM.

METHODS

A comprehensive literature search was conducted electronically using Embase and PubMed to retrieve studies assessing evidence for the efficacy and safety of vaginal laser therapy for GSM or vulvovaginal atrophy up to June 2021.

RESULTS

A total of 64 studies were finally included in the review. There were 10 controlled intervention studies, 7 observational cohort and cross-sectional studies and 47 before-after studies without a control group.

CONCLUSION

Vaginal laser seems to improve scores on the Visual Analogue Scale (VAS), Female Sexual Function Index (FSFI) and Vaginal Health Index (VHI) in GSM over the short term. Safety outcomes are underreported and short-term. Further well-designed clinical trials with sham-laser control groups and evaluating objective variables are needed to provide the best evidence on efficacy.
