abstract
We evaluated the associations between pelvic floor muscle strength and tone with sexual activity and sexual function in women with pelvic floor disorders.This was a secondary analysis of a multicenter study of women with pelvic floor disorders from the USA and UK performed to validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR). Participants were surveyed about whether they were sexually active and completed the PISQ-IR and the Female Sexual Function Index (FSFI) questionnaires to assess sexual function. Physical examinations included assessment of pelvic floor strength by the Oxford Grading Scale, and assessment of pelvic floor tone as per ICS guidelines.The cohort of 585 women was middle-aged (mean age 54.9 ± 12.1) with 395 (67.5 %) reporting sexual activity. Women with a strong pelvic floor (n = 275) were more likely to report sexual activity than women with weak strength (n = 280; 75.3 vs 61.8 %, p < 0.001), but normal or hypoactive pelvic floor tone was not associated with sexual activity (68.8 vs 60.2 %, normal vs hypoactive, p = 0.08). After multivariable analysis, a strong pelvic floor remained predictive of sexual activity (OR 1.89, CI 1.18-3.03, p < 0.01). Among sexually active women (n = 370), a strong pelvic floor was associated with higher scores on the PISQ-IR domain of condition impact (parameter estimate 0.20± 0.09, p = 0.04), and the FSFI orgasm domain (PE 0.51 ± 0.17, p = 0.004).A strong pelvic floor is associated with higher rates of sexual activity as well as higher sexual function scores on the condition impact domain of the PISQ-IR and the orgasm domain of the FSFI.
