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

To explore the therapeutic effect of the temperature-controlled radiofrequency technology in female sexual dysfunction (FSD).

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.

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).

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.
