The Relationship Between Pelvic Floor Function and Sexual Function in Perimenopausal Women

INTRODUCTION: Perimenopausal women with pelvic floor dysfunction have worse sexual function than women with functional pelvic floor muscle (PFM), especially in terms of libido, orgasm, sexual satisfaction, and total Female Sexual Function Index (FSFI) scores. AIM: To explore the relationship between pelvic floor muscle function, hormone levels and sexual function in perimenopausal women. METHODS: An analytical cross-sectional study was conducted in 252 women aged 40–55 without pelvic floor disease with FSFI, pelvic floor muscle strength and the hormone levels. MAIN OUTCOME MEASURE: The principle aim was to determine the relationships between sexual dysfunction, PFM strength, and hormone levels. RESULTS: In the functional PFM group, the proportion of menopausal hormone therapy was higher. The proportion of overweight in the dysfunctional PFM group was higher, and had more sexual desire disorder, more orgasm disorder, lower sexual satisfaction, and poor FSFI scores. The correlation between PFM strength, sexual function and female sex hormones suggested that PFM strength and libido, sexual satisfaction and FSFI score are significantly positively correlated, while PFM strength and sexual arousal disorder and vaginal lubricity had a positive correlation. In the multivariate analysis of the risk of sexual dysfunction among perimenopausal women, the higher the PFM strength, the lower the risk of sexual dysfunction. CONCLUSIONS: Perimenopausal women with pelvic floor dysfunction have worse sexual function than women with functional PFM, especially in obese women, those with central adiposity, and not using hormone replacement therapy. The PFM strength was weakly positively correlated with sexual arousal, orgasm, sexual satisfaction, and FSFI score. Zhuo Z, Wang C, Yu H, et al.
