Aerobic exercise in women with polycystic ovary syndrome improves ovarian morphology independent of changes in body composition

In a prospective study, eight women with polycystic ovary syndrome completed 16 weeks of individualized aerobic exercise training. Independent of changes in body weight and adiposity there was a statistically significant increase in aerobic fitness and insulin sensitivity and a statistically significant decrease in the total number of follicles measured by magnetic resonance imaging.
