Efficacy and safety of a device that combines multipolar radiofrequency with pulsed electromagnetic field for the treatment of vulvovaginal atrophy: a randomized, sham-controlled trial.

BACKGROUND: Vulvovaginal atrophy (VVA) negatively affects the sexual well-being and quality of life of postmenopausal women, yet it is underreported and undertreated.

AIM: The study sought to investigate the efficacy and safety of a nonablative, noncoagulative multipolar radiofrequency (RF) and pulsed electromagnetic field-based device (PEMF) in treatment of symptoms related to VVA.

METHODS: Seventy-six women ≥19 years of age with symptoms associated with VVA were enrolled into this prospective, randomized, sham-controlled, multicenter clinical study. Subjects were randomized to receive 3 RF + PEMF treatments (active group) or sham treatments (sham group) delivered to vaginal tissue at monthly intervals. The Vaginal Health Index (VHI), along with the Female Sexual Function Index (FSFI), subject sexual satisfaction and vaginal laxity (VL) score, treatment-associated pain, and adverse events were assessed at 4 follow-up (FU) visits between 1 and 12 months after treatment.

OUTCOMES: Changes from baseline VHI, pH, FSFI, VL, and sexual satisfaction scores between the active and sham groups were compared before and after treatment.

RESULTS: Mean VHI scores in the active group were significantly better compared with the sham group after treatment at all but the last FU visit (P < .001). A greater decrease in pH (active over sham) was seen at 1 and 4 months after treatment (P < .05). FSFI improvement was shown in the active group; however, it was not significantly better than sham improvement at all FU visits. Subject sexual satisfaction in the active group showed better improvement over sham at all FU visits (P < .05), while VL evaluations saw greater improvement in the active group at 4, 6, and 12 months posttreatment (P < .05). Treatment satisfaction was greater in the active group and pain was minimal in both groups. No serious adverse effects were reported.

CLINICAL IMPLICATIONS: As a noninvasive alternative to traditional surgical and topical procedures, 3 sessions of noninvasive combination RF/PEMF safely demonstrated improvement in symptoms related to VVA.

STRENGTHS AND LIMITATIONS: This study was strengthened by the randomized, sham-controlled design; large sample size; and extended FU period. The study assessments were decreased at later FU visits due to the global COVID pandemic, and this was a key limitation to the study.

CONCLUSION: Nonablative, noncoagulative multipolar RF/PEMF therapy was safe, improved symptoms associated with VVA, and improved female sexual function while yielding high subject satisfaction.
