Er:YAG Laser Combined With Vaginal Estriol for Genitourinary Syndrome of Menopause

Chronic hypoestrogenism in postmenopausal women significantly impacts the urogenital epithelium, leading to Genitourinary Syndrome of Menopause (GSM) and increasing susceptibility to gynecological infections due to vaginal pH elevation. Therapies using the Erbium:YAG (Er:YAG) 2940nm laser and low dose topical estrogen have demonstrated efficacy in improving vaginal trophism and restoring microbiota balance. This randomised, double-blind clinical study aims to assess the effects of combining Er: YAG laser therapy with vaginal estriol compared with estriol therapy alone in postmenopausal women with GSM. Sixty patients will be recruited and randomly assigned to two groups. All participants will receive low-dose topical estrogen therapy (estriol cream ) for 14 days, followed by twice-weekly applications until completing three laser sessions at four-week intervals. Group 1 (Sham) will receive the laser with minimal fluence (0.5J/cm²) applied to maintain blinding (auditory cues) below the threshold for biological tissue, while Group 2 , will undergo active laser treatment. Inclusion criteria include age 45-70 years, vaginal pH ≥5, absence of hormone therapy or energy-based intimate treatments for 180 days, and moderate vaginal atrophy symptoms (SCORE \>4). Exclusion criteria include abnormal cervicalvaginal cytology in the last six months, corticosteroid therapy within 90 days, and BMI ≥35kg/m². Assessments will occur at Baseline, 30 days after each laser session and 4 months af…
