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

Different effects of CO2 laser and estrogen treatment on vaginal mucosa microbiota and function in genitourinary syndrome of menopause patients

AIM

To characterize the effects of CO2 laser treatment and estrogen treatment on vaginal microbiota in patients with genitourinary syndrome of menopause (GSM).

METHODS

Sixty-four patients with genitourinary syndrome were divided into the estrogen group, the CO2 laser group, and the control group. The control group did not receive any treatment. Vaginal mucosa was collected after 3 and 12 months of treatment. The former was used for 16S rRNA sequencing, and the latter was used for pathological evaluation. Vaginal health and voiding function were assessed using the vaginal health index (VHI) scale and the UDI-6 scale at 3 and 12 months after treatment.

RESULTS

The results showed that both treatments reduced alpha diversity in the vaginal flora. Additionally, the abundance of 65 genera differed significantly between the treatment and control groups, with an increase in potentially beneficial bacteria such as Lactobacillus, IheB3_7, Mycoplasma urealyticum, and Streptococcus. In addition, the VHI and UDI-6 scores improved in both treatment groups compared to the control group after 3 months. Whereas VHI and UDI-6 scores were close to baseline in the estrogen group, and remained significantly improved in the CO2 laser group after 12 months. Pathological results showed that both methods improved the vaginal health status of patients with GSM after 12 months of treatment. However, the CO2 group exhibited a more significant increase in type III collagen.

CONCLUSIONS

Both CO2 laser and estrogen therapies can regulate the vaginal flora imbalance of GSM and improve the corresponding symptoms. However, the long-term efficacy of CO2 laser therapy is superior compared to estrogen therapy.

Lower Urinary Tract Symptoms in Greek Women After Menopause: The LADY Study

INTRODUCTION AND HYPOTHESIS

The genitourinary syndrome of menopause (GSM), apart from symptoms related to vulvovaginal atrophy (VVA), also consists of lower urinary tract symptoms (LUTS). Based on the common embryological origin of the genital and lower urinary system, the presence of estrogen receptors, and the high prevalence of VVA and LUTS in the menopausal population, the two conditions can coexist. This study is aimed at investigating the prevalence and risk factors of LUTS in a sample of Greek peri- and postmenopausal women.

METHODS

Four hundred and fifty (450) women, aged 40-70 years, attending three outpatient gynecology clinics for routine examination, completed a structured interview and responded to a validated questionnaire (International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms, ICIQ-FLUTS).

RESULTS

Urinary urgency or frequency affected 51.6% and dysuria 43.6% of the participants. Mild urgency or frequency was described by 25.6%, moderate by 14.4%, and severe by 11.6% of the women. Mild dysuria was reported by 26.26%, moderate by 5.8%, and severe by 11.6%. Age, weight, BMI, and number of pregnancies and abortions correlated with a higher ICIQ-FLUTS score. Women with moderate/severe symptoms of VVA, such as irritation, a burning sensation, and pruritus of the vulva or vagina, had a higher ICIQ-FLUTS score than women without such symptoms (beta coefficient 2.42, CI 1.204, 3.635, p < 0.001).

CONCLUSIONS

Lower urinary tract symptoms are very common among peri- and postmenopausal women and are linked to symptoms of VVA. Our data support the need for prompt evaluation of women transitioning to menopause, as these symptoms compromise the quality of life.

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.

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.

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.

Information and oncosexological management in breast cancer patients

OBJECTIVES

Breast cancer treatment is a particularly high-risk situation for the deterioration of sexual health, leading to an alteration in body image and physical deteriorations such as vaginal trophicity. The aim of this study was to evaluate the information received by patients concerning this alteration of their sexual health in relation to their treatment, and to identify their expectations and needs in terms of oncosexual management.

STUDY DESIGN

A bicentric qualitative retrospective study was conducted, involving women aged 18 to 80, treated for breast cancer by total or partial mastectomy after 2014 and having had a follow-up consultation between July and December 2019. Data were collected using medical files and a de-identified questionnaire sent by post or e-mail after obtaining consent. The main outcome measures were the proportion of patients who received informations about oncosexology and those who felt impact on their sexual health.

RESULTS

Of the 274 patients included in the study, 60% said they had received no information about the sexological side effects of their disease or treatment. Of these, 62.5% dared not talk about it during consultation. Patients were keen to receive oncosexological advice or treatment from a specialized nurse or doctor. In 76.1% of cases, patients declared that they had been sexually active in the year prior to their cancer diagnosis, compared with 54.94% after treatment. They reported a loss of femininity in 24% of cases, and 40.5% had no sexual desire.

CONCLUSION

Women treated for breast cancer report a lasting alteration in their body image and sexual activity. Information on the impact of the disease and its treatment on sexual health is inadequate, even though patients are keen to receive specialized care with professional sexology consultations. The impact of breast cancer on sexual health should systematically explained to the patients, especially as treatment options exist and can be offered.

A practical guide to managing genitourinary syndrome of menopause in primary care

ABSTRACT

Females spend a third to half of their life in menopause, and the number of US females in menopause is growing. A high percentage of postmenopausal females experience bothersome, sometimes debilitating genitourinary symptoms, which can affect quality of life. The genitourinary syndrome of menopause (GSM) describes the condition previously referred to as vulvovaginal atrophy, atrophic vaginitis, or urogenital atrophy. Of concern, many patients with symptoms of GSM have never been asked about nor have they initiated conversations about these concerns with a healthcare provider. This article addresses the need to improve screening, identification, and patient-centered management in primary care of females with GSM.

Effects of Non-Ablative Solid-State Vaginal Laser (SSVL) for the Treatment of Vulvovaginal Atrophy in Breast Cancer Survivors after Adjuvant Aromatase Inhibitor Therapy: Preliminary Results

BACKGROUND

One of the side effects of anti-estrogen treatments in breast cancer survivors (BCSs), especially with aromatase inhibitor (AI) treatment, is the frequent appearance of vulvo-vaginal atrophy (VVA). We aim to evaluate the efficacy, safety and feasibility of a new type of non-ablative Solid-State Vaginal Laser (SSVL) treatment in BCSs with VVA.

METHODS

A total of 30 BCSs with a history of AI use and symptoms of VVA were treated with a non-ablative SSVL (LASEmaR 1500™-EUFOTON)in this non-randomized pilot study. The effects of the laser have been evaluated at baseline, 10 wk and 24 wk using a visual analogue scale (VAS), the Vaginal Health Index (VHI), the Vulvar Health Index (VuHI), the Female Sexual Function Index (FSFI), the EORTC QLQ-BR23, the Vaginal Maturation Index (VMI) and vaginal pH.

RESULTS

At 10-week follow-up vs. baseline there were no statistically significant differences in FSFI, lubrication and EORTC QLQ-BR23. In all the subjective (dyspareunia, VHI, VuHI, FSFI, QLQ) and objective parameters (VMI and pH) there was a statistically significant improvement at the 6-month follow-up. Satisfaction was very high (4.7 out of 5), with 95.7% of patients being satisfied, more than or very satisfied.

CONCLUSIONS

Preliminary results of SSVL treatment of VVA and dyspareunia in BCSs after AI treatment suggest clinical improvement, without relevant side effects and with a high degree of satisfaction.

Genitourinary Syndrome of Menopause in Breast Cancer Survivors: Current Perspectives on the Role of Laser Therapy

Genitourinary syndrome of menopause (GSM) is a frequent consequence of iatrogenic menopause or anti-estrogenic adjuvant therapies in breast cancer survivors (BCSs). GSM may profoundly affect sexual health and quality of life, and a multidimensional unique model of care is needed to address the burden of this chronic heterogeneous condition. Severe symptoms may be insufficiently managed with non-hormonal traditional treatments, such as moisturizers and lubricants, recommended as the first-line approach by current guidelines, because concerns exist around the use of vaginal estrogens, particularly in women on aromatase inhibitors (AIs). Vaginal laser therapy has emerged as a promising alternative in women with GSM who are not suitable or do not respond to hormonal management, or are not willing to use pharmacological strategies. We aim to systematically review current evidence about vaginal laser efficacy and safety in BCSs and to highlight gaps in the literature. We analyzed results from 20 studies, including over 700 BCSs treated with either CO2 or erbium laser, with quite heterogeneous primary outcomes and duration of follow up (4 weeks-24 months). Although evidence for laser efficacy in BCSs comes mostly from single-arm prospective studies, with only one randomized double-blind sham-controlled trial for CO2 laser and one randomized comparative trial of erbium laser and hyaluronic acid, available data are reassuring in the short term and indicate effectiveness of both CO2 and erbium lasers on the most common GSM symptoms. However, further studies are mandatory to establish long-term efficacy and safety in menopausal women, including BCSs.

The effect of CO2 laser therapy on vaginal microcirculatory parameters in an animal model for genitourinary syndrome of menopause

BACKGROUND

Vaginal laser therapy for the treatment of genitourinary syndrome of menopause (GSM) has been introduced to the market with limited (pre)clinical and experimental evidence supporting its efficacy. It is suggested that vaginal laser therapy increases epithelial thickness and improves vascularization, but the underlying biological working mechanism has not been substantiated yet.

OBJECTIVE

To evaluate the effects of CO₂ laser therapy on vaginal atrophy using noninvasive incident dark field (IDF) imaging in a large animal model for GSM.

DESIGN, SETTING, AND PARTICIPANTS

An animal study was conducted between 2018 and 2019 and included 25 Dohne Merino ewes, of which 20 underwent bilateral ovariectomy (OVX) to induce iatrogenic menopause, and 5 did not. The total study duration was 10 months.

INTERVENTIONS

Five months after OVX, ovariectomized ewes received monthly applications of CO₂ laser (n = 7), vaginal estrogen (n = 7), or no treatment (n = 6) for 3 months. IDF imaging was performed monthly in all animals.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary outcome was the proportion of image sequences containing capillary loops (angioarchitecture). Secondary outcomes included focal depth (epithelial thickness), and quantitative measures of vessel density and perfusion. Treatment effects were evaluated using ANCOVA and binary logistic regression.

RESULTS AND LIMITATIONS

Compared to OVX-only, ewes treated with estrogen demonstrated a higher capillary loops proportion (4% vs. 75%, p < 0.01), and higher focal depth (60 (IQR 60-80) vs. 80 (IQR 80-80) p < 0.05). CO₂ laser therapy did not change microcirculatory parameters. As the ewes' vaginal epithelium is thinner than that of humans, it may demand different laser settings.

CONCLUSIONS

In a large animal model for GSM, CO₂ laser therapy does not affect microcirculatory outcomes related to GSM, whereas vaginal estrogen treatment does. Until more homogeneous and objective evidence about its efficacy is available, CO₂ laser therapy should not be adopted into widespread practice for treating GSM.

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.

Superficial dyspareunia treatment with hyperstacking of erbium:yttrium-aluminum-garnet SMOOTH laser: a short-term, pilot study in breast cancer survivors

OBJECTIVE

This prospective pilot study aimed to evaluate the effects of a modified vaginal erbium laser (VEL) protocol, using the hyperstack mode on the vaginal vestibulum and introitus to treat superficial dyspareunia in postmenopausal breast cancer survivors suffering from the genitourinary syndrome of menopause.

METHODS

In this pilot, prospective, randomized study, two groups of postmenopausal women suffering from superficial dyspareunia were included: 34 women (VEL group) were treated with erbium laser crystal yttrium-aluminum-garnet (XS Fotona SMOOTH; Fotona, Ljubljana, Slovenia) with a wavelength of 2,940 nm; for the other 34 (hyperstack group), a modified second step of the VEL protocol for the treatment of vestibulum and introitus was used, with hyperstacked (repeating a number of) subablative, long pulses with very low fluences. For each group, three laser applications at 30-day intervals were performed. Symptoms were assessed before, after each application, and after 1 and 3 months from the last laser application, using the visual analog scale score for superficial dyspareunia.

RESULTS

Superficial dyspareunia improved in both groups over time (P < 0.001), regardless of age and years since menopause status. The reduction in visual analog scale score after the third laser application was 58% in VEL versus 73.5% in hyperstack. The hyperstack group, since the first laser application, showed a greater (P < 0.001) and persistent improvement of superficial dyspareunia.

CONCLUSIONS

The hyperstack treatment of the introitus and vestibulum in breast cancer survivors leads to a more significant improvement in superficial dyspareunia than the VEL alone.

[High-intensity laser therapy in clinical medicine: scientometric analysis of evidence of effectiveness]

INTRODUCTION

High-intensity laser technologies are widely used in modern restorative medicine, and indications for their use are expanding annually. These technologies are effective, potentially safe methods of treating many diseases. with pronounced therapeutic effects.

PURPOSE OF RESEARCH

Analysis of scientific evidence of the effectiveness and safety of high-intensity laser therapy in patients with various diseases.

MATERIAL AND METHODS

A comprehensive scientometric analysis of evidence-based studies of the effectiveness and safety of high-intensity laser therapy methods was carried out according to electronic databases (Google scholar, PEDro, PubMed, Cochrane DATABASE) for the period from 2006 to 2021.

RESULTS

High-intensity laser therapy has a wide range of significantly pronounced therapeutic effects. and it is an effective method of treating patients with various diseases. Various technologies and methods of its application are widely used in various fields of clinical medicine. Individually developed therapy protocols are needed, with optimal exposure parameters for each patient, intervals between procedures.

CONCLUSION

It is advisable to develop more reliable and standard evaluation criteria, regular generalization and analysis of existing evidence, careful planning and implementation of further large-scale randomized controlled trials to study the effects of high-intensity laser radiation both as a single effect and as part of combinations with other treatment methods. The effectiveness of combination therapy requires further analysis in the course of conducting new benign clinical trials.

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.

Comparison of Severity of Genitourinary Syndrome of Menopause Symptoms After Carbon Dioxide Laser vs Vaginal Estrogen Therapy: A Systematic Review and Meta-analysis

IMPORTANCE

Vaginal estrogen for genitourinary syndrome of menopause (GSM) should be used with caution in women with contraindications, highlighting the need for effective treatment alternatives.

OBJECTIVE

To compare the severity of GSM after vaginal laser vs estrogen therapy.

DATA SOURCES

The PubMed, Embase, and Cochrane Library databases were searched for articles published from database inception to April 8, 2022, with no language restrictions. Reference lists were also searched.

STUDY SELECTION

Randomized clinical trials (RCTs) that compared the use of lasers with vaginal estrogen in adults were selected.

DATA EXTRACTION AND SYNTHESIS

Two investigators independently extracted data from included studies. The Cochrane risk of bias tool for RCTs was used to assess risk of bias of each study. A random-effects model was used to pool mean differences (MDs) with 95% CIs.

MAIN OUTCOMES AND MEASURES

Primary outcomes were Vaginal Analog Scale (VAS; higher scores indicate severer symptoms), Vaginal Health Index (VHI; higher scores indicate better vaginal health), Vaginal Maturation Index (VMI; higher scores indicate higher estrogen effect on the vaginal epithelium), Female Sexual Function Index (FSFI; higher scores indicate better female sexual function), and Sexual Quotient-Female (SQ-F; higher scores indicate better female sexual function) questionnaire scores. Urinary symptoms were assessed as an additional outcome. Data analyses were performed from April 9 to 12, 2022.

RESULTS

A total of 6 RCTs with 270 women with GSM were included (135 were randomized to laser therapy and 135 to estrogen therapy; mean age ranged from 54.6 to 61.0 years). No significant differences were found between carbon dioxide laser and vaginal estrogen from baseline to the end of follow-up in overall VAS scores (MD, -0.16; 95% CI, -0.67 to 0.36; I2, 33.31%), VHI (MD, 0.20; 95% CI, -0.56 to 0.97; I2, 83.25%), VMI (MD, -0.56; 95% CI, -1.14 to 0.02; I2, 35.07%), FSFI (MD, -0.04; 95% CI, -0.45 to 0.36; I2, 41.60%), and SQ-F (P = .37 based on 1 study). Other questionnaire-based outcome measures demonstrated no difference between groups from baseline to the end of follow-up for changes in urinary symptoms.

CONCLUSIONS AND RELEVANCE

This systematic review and meta-analysis of RCTs found that vaginal laser treatment is associated with similar improvement in genitourinary symptoms as vaginal estrogen therapy. Further research is needed to test whether vaginal laser therapy could be a potential treatment option for women with contraindications to vaginal estrogen.

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.

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.

Menopause and female sexual dysfunctions (FSDs)

Biological and psycho-relational factors contribute equally to the development of sexual symptoms and associated distress, a key element to diagnose female sexual dysfunctions (FSDs) in menopausal women. Consultation at midlife represents an optimal time to discuss sexual life, and healthcare providers (HCPs) have to be proactive in rising the conversation, as patients may not report their sexual concerns spontaneously. An accurate sexual history is essential to characterize the primary symptom, determine the impact on patient's quality of life and identify risk and precipitating factors. Among FSDs, hypoactive sexual desire disorder (HSDD) is very frequent at midlife together with genitourinary syndrome of menopause (GSM), a chronic condition negatively affecting the full sexual response. A multidimensional approach targeted to the patient's characteristics, goals and expectations is mandatory and should start from educative counselling and correction of modifiable risk factors. When specific treatments are required, they should include non-pharmacological and pharmacological options, often prescribed in combination to address concomitantly the biological and psychosocial components of FSDs.
