Introduction and hypothesis: This study aims to evaluate the association between pelvic floor muscle (PFM) strength and sexual functioning.
Methods: Retrospective chart review of consecutive all women who were referred with a primary complaint of sexual dysfunction. Women underwent standardized clinical evaluation including pelvic muscle strength which was ranked from 0 (weak) to 2 (strong). The duration of pelvic muscle contraction was also recorded in seconds. Sexual function was evaluated by using a validated questionnaire, the Female Sexual Function Index (FSFI).
Results: One hundred seventy-six women with a mean age of 37 +/- 11 years were included. Women with strong or moderate PFM scored significantly higher on the FSFI orgasmic and arousal domains than women with weak PFM (5.4 +/- 0.8 vs. 2.8 +/- 0.8, and 3.9 +/- 0.5 vs. 1.7 +/- 0.24, respectively; P < 0.001). The duration of PFM contraction was correlated with FSFI orgasmic domain and sexual arousal (r = 0.26, P < 0.001; r = 0.32, P < 0.0001, respectively).
Conclusions: Our findings suggest that both the orgasm and arousal function are related to better PFM function.
