Doppler analysis of the uterine arteries and ovarian stroma was performed b
y transvaginal ultrasound in 24 patients with polycystic ovary syndrome (PC
OS) and 22 ovulatory women. Vascularization of the ovarian stroma was more
abundant in patients with PCOS than in control women, but no significant di
fference 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). Th
e mean PI of the uterine arteries was significantly higher in the PCOS grou
p (PI = 3.7 +/- 0.8) than in the control group (PI = 2.9 +/- 0.4). In the p
atients with PCOS, no correlation was observed between PI and luteinizing h
ormone, testosterone or androstenedione levels. Obesity had no effect on ut
erine artery Pl, with no significant differences in this index when the 3 g
roups were subdivided into obese and non-obese groups. Copyright (C) 2001 S
