Comparison of promestriene with vaginal fractional CO2 laser and radiofrequency treatments of genitourinary syndrome of menopause

Abstract

ObjectiveTo compare the effects of fractional CO2 laser and microablative fractional radiofrequency treatment with promestriene topical estrogen on sexual function and genitourinary syndrome of menopause symptoms. MethodsThis was a prospective randomized open-label clinical trial conducted with 62 postmenopausal women assigned to three intervention groups: a) topical promestriene for 90 days (n = 17); b) fractional CO2 laser treatment (n = 24); and c) microablative fractional radiofrequency treatment (n = 21). Each of the latter two groups underwent three treatment sessions at 4-week intervals. At baseline and at the end of the study, all participants had a gynecological examination that included vaginal pH measurement, and the completion of the Vaginal Symptom Score, the Vaginal Health Index, and the Female Sexual Function Index. For the energy treatment groups, adverse effects were evaluated after each session. Group homogeneity was assessed at baseline, and results were evaluated over time (from baseline to the end of treatment) and between groups over time. ResultsAll baseline parameters were similar among studied groups. At the end of the study, all 3 treatments had produced similar effects: a reduction of vaginal pH, and an improvement of vulvovaginal symptoms (Vaginal Symptom Score and Vaginal Health Index scores) as well as sexual function (higher total Female Sexual Function Index scores, and in the desire, arousal, lubrication and pain domain scores), with no differences observed between groups. Side-effects were slight for both energy treatment groups, mainly represented by vaginal discharge. ConclusionThe present study suggests that the two energy treatments were efficient along with promestriene at improving postmenopausal genitourinary and sexuality symptoms.Clinical trial identification numberNCT04717245.
