Laxity of the Vaginal Introitus After Childbirth: Nonsurgical Outpatient Procedure for Vaginal Tissue Restoration and Improved Sexual Satisfaction Using Low-Energy Radiofrequency Thermal Therapy

Abstract

Vaginal childbirth may result in vaginal introital laxity, altered genital sensation during sexual intercourse, and reduced sexual satisfaction. We report the long-term effectiveness of a single nonsurgical procedure with radiofrequency (RF) energy for laxity at the vaginal introitus. Prospective single-arm study of 30 premenopausal women (21-52 year) with one 30-minute office procedure using RF applied to the vaginal introitus; 12-month outcome assessments included the linguistic validated Japanese versions of the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R) and the Vaginal Laxity and Sexual Satisfaction Questionnaires. Sexual function improved significantly throughout 6 months (30 subjects); mean FSFI total score was 22.4±6.7 before treatment and then improved to mean 26.0±5.8 at month 6 (P=0.002), inclusive of improved scores in five of six FSFI domains except desire (P<0.001 -<0.01). In the 22 of 30 subjects remaining evaluable at 12 months, the mean was 26.0±5.2 (P=0.08). Distress related to sexual activity decreased significantly; baseline FSDS-R mean score of 15.8±11.7 improved to 9.8±8.0 at one month and was sustained throughout 12 months (P<0.001 - 0.002). Subjects reported decreased vaginal laxity within the first month after the procedure (P<0.001); responses peaked, and effectiveness was sustained through 12 months (P<0.001). A single nonsurgical office-based RF procedure for vaginal introital laxity achieved significant and sustainable 12-month effectiveness with respect to improved integrity at the vaginal introitus and improved sexual satisfaction. Treatment was well-tolerated with no adverse events.
