Abstract
ObjectiveTo evaluate uterine artery blood flow using pulsed Doppler, and endometrial and subendometrial microvascularization using three-dimensional (3D) power Doppler, in women with unexplained infertility. Study designIn a prospective clinical trial at a university teaching hospital, 40 women with unexplained infertility were compared to 40 fertile parous controls. In the mid-luteal (peri-implantation) phase, the endometrial thickness and volume, uterine artery pulsatility index (PI) and resistance index (RI), endometrial and subendometrial 3D power Doppler vascularization index (VI), flow index (FI), and vascularization flow index (VFI), and serum estradiol and progesterone levels were measured in both groups. ResultsThe uterine artery PI (P=0.003) and RI (P=0.007) were significantly increased and the endometrial VI (P=0.029), FI (P=0.031), and VFI (P=0.001) and subendometrial VI (P=0.032), FI (P=0.040), and VFI (P=0.005) were significantly decreased in the unexplained infertility group. The endometrial thickness and volume and serum estradiol and progesterone levels, however, were not significantly different between the two groups. ConclusionPeri-implantation endometrial perfusion is impaired in women with unexplained infertility: Doppler study of uterine hemodynamics should therefore be considered in infertility work-up.
