Background: Fibromyalgia (FM) is characterized by chronic and widespread pain, sleep disturbances, fatigue, psychological distress and morning stiffness. These patients also present symptoms such as depression, sexual dysfunctions and reproductive problems. Sexuality involves several aspects, including pelvic floor functionality, and one question is whether the sexual performance of women with fibromyalgia is associated with pelvic floor function or other characteristics of the disease.

Objective: The aim of this study was to gauge the association between perineal function and sexual performance in women with and without fibromyalgia.

Methods: We performed a cross-sectional study with 109 sexually active women from 19 to 65 years of age, either suffering from fibromyalgia (FM group, n = 51) or free from fibromyalgia (non-FM group, n = 58). Perineal function was measured with the use of perineometry and digital vaginal palpation (PERFECT Scheme), while sexual performance was assessed by the Sexual Quotient Female questionnaire (QS-F).

Results: Patients with fibromyalgia presented poor sexual performance compared to those without fibromyalgia (QS-F score 58 (32-66) vs. 66 (56-70); p = 0.002) as well as lower pelvic floor muscle strength measured by perineometry (32.5 (18.2-40.5) vs. 37.9 (23.4- 57.3); p = 0.03). Patients without fibromyalgia presented a positive correlation between perineometry and QS-F (r = 0.22; p = 0.038), while those with fibromyalgia presented no correlation between those two variables (r = 0.22; p = 0.12). The regression model showed an association between sexual performance and the presence of fibromyalgia, pelvic floor muscle strength (perineometry) and age, according to the following equation: sexual performance = 48.52 + (9.5 * non-FM group) + (0.23 * perineometry)-(0.4 * age), with adjusted R = 0.19.

Conclusion: Women with FM present poor sexual performance and lower pelvic floor muscle strength compared to those without FM. However, the correlation between these variables among women without FM was not observed in women with FM. Sexual performance showed a positive association with absence of fibromyalgia and higher pelvic floor muscle strength, and a negative association with age.
