Therapeutic effect of the temperature-controlled radio frequency technology in female sexual dysfunction

Abstract

Objectives: To explore the therapeutic effect of the temperature-controlled radiofrequency technology in female sexual dysfunction (FSD). Material and methods: From July 2020 to June 2021, patients with FSD who visited the Gynecology Clinic of Peking University Shenzhen Hospital were treated with the temperature-controlled radiofrequency technology once every two weeks, for a total of five times. The therapeutic effect was objectively evaluated with pelvic floor dysfunction (PFD) indicators (FSFI score, pelvic floor muscles surface electromyography, sexual function test). The pre- and post-treatment (2 weeks)/follow-up (3 months) results were compared to evaluate the feasibility of this technology for treating FSD, as well as using PFD-related indicators in objective evaluation of FSD patients. Results: Fifty patients completed treatment; 31 patients completed follow-up. The mean FSFI score for post-treatment/follow- up was significantly higher than pre-treatment (p < 0.05). There were no significant changes in the mean pelvic floor resting surface myoelectric potential and its variability and mean myoelectric potential of sexual function test between pre- and post-treatment/follow-up. The mean surface myoelectric potential of the patients’ type I and II muscle fibers of the pelvic floor for post-treatment/follow-up was significantly higher than pre-treatment (p < 0.05). The mean peak myoelectric potential for post-treatment was significantly higher than pre-treatment (p < 0.05). Conclusions: Temperature-controlled radiofrequency technology has a certain therapeutic effect on FSD. Pelvic floor surface electromyography and sexual function test can be used as an objective indicator for PFD in FSD patients. Subsequent studies may involve a larger size sample and evaluate the effect over a consecutive time-point, to develop a better therapeutic approach.
