About this study

Official title: Efficacy of Non-Ablative Radiofrequency on Vaginal and Sexual Health in Postmenopausal Women: a Randomized Clinical Trial

This study will test if non-ablative monopolar radiofrequency can help improve vaginal tissue and reduce symptoms of Genitourinary Syndrome of Menopause (GSM) in postmenopausal women. The study is a randomized, sham-controlled clinical trial in which participants and outcome assessors were masked to treatment allocation. The study will examine the impact of the treatment on sexual function, vaginal health, and quality of life over an extended period. There will be two groups in the study: one will receive the non-ablative monopolar radiofrequency treatment, and the other will receive the placebo treatment. Participants will have six treatment sessions and will be checked at the start, end, and three months post-treatment.

Read the detailed description

The purpose of this study is to evaluate the efficacy of non-ablative monopolar radiofrequency (RF) treatment in improving vaginal tissue regeneration and alleviating symptoms of Genitourinary Syndrome of Menopause (GSM) in postmenopausal women. This randomized clinical trial will include two groups: one receiving the active RF treatment and the other receiving a placebo treatment. The study will include six treatment sessions for each participant, with evaluations conducted at baseline, at the end of the treatment period, and three months post-treatment.

The sample size was calculated to detect a between-group difference of 4.5 points in the total FSFI score, with a two-sided α of 0.05, 80% power, and an assumed standard deviation of 6. Allowing for an anticipated 10% attrition rate, 31 participants per group were required (total N = 62).

Participants will be postmenopausal women who have experienced more than one year of amenorrhea and exhibit symptoms of GSM, such as vaginal dryness, irritation, and sexual dysfunction.

The primary outcome measures will include improvements in vaginal health assessed through clinical examination and patient-reported outcomes related to sexual function.

Secondary outcome measures will involve the analysis of vaginal pH, the maturation index of vaginal epithelial cells, and any adverse events reported during the study. The intervention involves the use of a non-ablative monopolar RF device applied intracavitarily. The placebo group will undergo the same procedure without the active RF component.

The study is conducted in accordance with ethical standards and has been reviewed and approved by the Ethics Committee for Clinical Research with Medicines of the City of Toledo. Data will be collected and analyzed to determine the effectiveness of the treatment in comparison to the placebo, and results will contribute to the understanding of non-ablative RF treatments in menopausal health.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Non-ablative monopolar radiofrequency treatmentDevice

    Protocol for the experimental group:

    Tissue preparation phase: 5 minutes with the circular resistive monopolar electrode, applying slow circular or semicircular movements in the perineal area. The temperature will be gradually increased based on the patient's temperature perception, ensuring it remains comfortable (approximately 5 out of 10).

    Main phase: 10 minutes using the intracavitary capacitive electrode connected to the PLUMA handle, lightly resting it on the tissues and continuously moving the electrode. The intravaginal temperature was maintained at 41-43°C throughout the 10-minute intracavitary application.

    Final phase: 5 minutes with the circular resistive monopolar electrode, applying it similarly to the preparatory phase, with a subthermal effect, reaching a self-reported thermal sensation of 3 to 4 out of 10.

    Participants in this group will receive the same treatment protocol, but with radiofrequency energy disabled.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Female Sexual Function Index (FSFI)

    Multidimensional questionnaire evaluates sexual function over the past 4 weeks. The total score ranges from 2.0 (severe dysfunction) to 36.0 (no dysfunction). Sexual dysfunction was defined as a score equal to or below 26.55

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

  2. Change in Vaginal Health Index (VHI)

    A tool that evaluates five parameters: vaginal elasticity, vaginal secretion (type and consistency), pH, mucosal epithelial integrity, and vaginal moisture. Each parameter was scored on a scale from 1 (most unfavorable condition) to 5 (optimal condition), with a maximum possible score of 25 points. In cases where the score was below 15, the vagina was considered atrophic.

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

Secondary outcomes (17)

    Assessed by Female Sexual Function Index in individual domain of sexual desire. Score from 1,2 (worst) to 6 (best)

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

  2. Change in sexual arousal

    Assessed by Female Sexual Function Index in individual domain of sexual arousal. Score from 0 (worst) to 6 (best)

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

  3. Change in sexual lubrication

    Assessed by Female Sexual Function Index in individual domain of sexual lubrication. Score from 1,2 (worst) to 6 (best)

    Assessed by Female Sexual Function Index in individual domain of sexual orgasm. Score from 0 (worst) to 6 (best)

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

  5. Change in sexual satisfaction

    Assessed by Female Sexual Function Index in individual domain of sexual satisfaction. Score from 0.8 (worst) to 6 (best)

    Measured: Baseline, end of treatment period (6 weeks), and three months post-treatment.

  6. Change in sexual pain

    Assessed by Female Sexual Function Index in individual domain of sexual pain. Score from 0 (the worst possible pain) to 6 (no pain).

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Female Sexual Function Index (FSFI) (time frame: Baseline, end of treatment period (6 weeks), and three months post-treatment.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06925139, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2026.
