The advent of high-resolution transvaginal ultrasound scanning introduced new research possibilities for patients with polycystic ovaries. The knowledge of the ovarian hemodynamics is a prerequisite for understanding the pathophysiological behaviour of polycystic ovaries. The authors consider the possibility of using color Doppler for a better definition of polycystic ovaries. The findings suggest that increased stromal blood vessels with low resistance and increased pulsatility index of the uterine arteries are to be new parameters to assist in the ultrasound diagnosis of polycystic ovary syndrome. This is a preliminary conclusion and further investigations are necessary to confirm this proposition.
