Abstract
AIMS: To evaluate the electrical activity of the pelvic floor muscles (PFM) in women with polycystic ovary syndrome. METHODS: Forty-two women with polycystic ovary syndrome (PCOS group) and 13 premenopausal women (control group) were recruited in this cross-sectional study. Total testosterone and estradiol were measured and muscle tone and maximum voluntary contraction (MVC) of PFM were determined by surface electromyography. RESULTS: There was a difference in muscle tone (PCOS = 59.9 µV and Control group = 25.5 µV; P < 0.0001) and MVC (PCOS = 159.7 µV and Control group = 63.7 µV; P < 0.0002) between groups. The concentration of estradiol and testosterone showed a strong correlation with tone (r = 0.9, r = 0.8 respectively) and MVC (r = 0.9, r = 0.9 respectively) in women with PCOS. The control group exhibited a strong correlation between testosterone and muscle tone (r = 0.9) and MVC (r = 0.9). CONCLUSION: Women with PCOS display higher electromyographic values than those in premenopause. Moreover, electrical activity showed a positive relation with estradiol and testosterone concentrations. Although PCOS is a heterogeneous disorder affecting young women, it is suggested that the hyperandrogenic state associated with PCOS is a protective factor for PFM. Neurourol.
