title: Doppler study of the uterine arteries and ovarian stroma in patients with polycystic ovary syndrome.
abstract: Doppler analysis of the uterine arteries and ovarian stroma was performed by transvaginal ultrasound in 24 patients with polycystic ovary syndrome (PCOS) and 22 ovulatory women. Vascularization of the ovarian stroma was more abundant in patients with PCOS than in control women, but no significant difference in the mean pulsatility index (PI) was observed between groups (1.14 +/- 0.28 for the PCOS group and 1.05 +/- 0.19 for the control group). The mean PI of the uterine arteries was significantly higher in the PCOS group (PI = 3.7 +/- 0.8) than in the control group (PI = 2.9 +/- 0.4). In the patients with PCOS, no correlation was observed between PI and luteinizing hormone, testosterone or androstenedione levels. Obesity had no effect on uterine artery PI, with no significant differences in this index when the 3 groups were subdivided into obese and non-obese groups.
