Ultrasound and Electromyography Evaluation of the Pelvic Floor Muscle in Hyperandrogenic Women

Hypothesis / aims of study Androgens and anabolic steroids increase muscle mass and strength in general [1]. Due to the characteristics of hyperandrogenism in PCOS, it is plausible that women with PCOS may have increased muscle mass compared with controls [1]. The hyperandrogenism may lead to improve muscle function including pelvic floor muscle (PFM). In a recent study we found that women with PCOS presented less complaints of urinary incontinence than controls, however no difference was found in relation to pelvic floor muscle strength measured by perineometry [2]. There is no single method able to evaluate all functions of PFM. The sum of more than one method can gather more precise information about PFM function [3]. The aim of this secondary analysis was to compare PFM activity and thickness between women with and without PCOS.
