Objectives: To assess the correlation between hormonal status and PF muscle strength. Methods: 140 continent women were prospectively evaluated, and divided into four groups according to age: G1 (n = 34) 30-40 years, G2 (n = 38) 41-50 years, G3 (n = 35) 51-60, and G4 (n = 33) older than 60 years. The following parameters were evaluated: demographic data using clinical questionnaire; hypermobility of the bladder neck using the swab test; vaginal trophism by gynecological examination; hormonal status of the vagina by cytology; muscle strength of the PF using perineometer and electromyography (EMG). Results: There was no statistical difference between PF muscle strength, demographic characteristics, vaginal trophism, and hypermobility of the bladder neck in the different groups (p > 0.05). There was a larger number of atrophic women among those over 60 years of age. Vaginal trophism assessed by physical examination was highly consistent with the findings of colpocytology (Kappa = 0.888). We found, however, that women with hypermobility by EMG had less muscle strength as compared to those with no hypermobility. Conclusion: Although vaginal atrophy is more intense in women older than 60 years, no difference was found in muscle strength of the PF during the physiological aging process. As a consequence, it is not possible to state that trophism is the only factor related to PF muscular strength, thus precluding the selection of women who should be referred to prophylaxis.
