Effect of Single-Treatment, Surface-Cooled Radiofrequency Therapy on Vaginal Laxity and Female Sexual Function: The VIVEVE I Randomized Controlled Trial
Bibliographic record
Abstract
Abstract Introduction Vaginal laxity is a highly prevalent and undertreated medical condition. Aim To evaluate the efficacy and safety of surface-cooled, monopolar radiofrequency (RFc) therapy for the treatment of vaginal laxity in the VIVEVE I trial. Methods The VIVEVE I trial was a prospective, randomized, single-blinded, and sham-controlled study. Nine study centers in Canada, Italy, Spain, and Japan participated. Women presenting with vaginal laxity were screened and informed consent was obtained. Major study inclusion criteria were premenopausal status, age at least 18 years, at least one full-term vaginal delivery, and normal genito-pelvic examination results. Enrolled subjects were randomized (2:1) to receive RFc therapy (Active [90 J/cm2] vs Sham [1 J/cm2], respectively) delivered to the vaginal tissue. Main Outcome Measures The primary efficacy outcome was the proportion of randomized subjects reporting “no vaginal laxity” (Active vs Sham) at 6 months postintervention, which was assessed using the Vaginal Laxity Questionnaire. Treatment-emergent adverse events were evaluated in all treated subjects. Secondary efficacy end points included change on the Female Sexual Function Index (FSFI) and the revised Female Sexual Distress Scale (FSDS-R). Results No vaginal laxity was achieved by 43.5% and 19.6% (P = .002) in the Active and Sham groups, respectively. Differences in FSFI and FSDS-R total scores (Active vs Sham) were 1.8 (P = .031) and −2.42 (P = .056), respectively, in favor of Active treatment. Treatment-emergent adverse events were reported by 11.1% and 12.3% of subjects in the Active and Sham arms, respectively. Conclusion The VIVEVE I trial is the first randomized, controlled, blinded, clinical study of RFc for the treatment of vaginal laxity. A single treatment of RFc therapy was found to be safe and associated with both improved vaginal laxity and improved sexual function. The results from this trial support the use of a novel non-surgical therapy for vaginal laxity, a prevalent and undertreated condition.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
