Abstract Endometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity. The aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness and pattern in uterine receptivity in infertile women treated with assisted reproductive technologies (ART). A total of 40 women were recruited from our ART program from November 2012 to November 2014. In the first stage, down regulation was done using GnRH-a and then ovarian hyperstimulation was initiated with human menopausal gonadotrophin and intracutoplasmic sperm injection (ICSI) procedures were performed. After that the endometrial thickness and pattern was assessed at the HCG day injection. Then, the endometrial blood flow distribution pattern was determined by color Doppler ultrasonography and its characteristics were compared between pregnant (n = 11) and non-pregnant (n =29) women. There was significant association between implantation rate and endometrial thickness but no assotiationt found between the implantation and endometrial pattern. zone of vascular penetration. Among all women, fertility occurred in 56 (32.2%) women. Endometrial–subendometrial blood flow (according the findings of Doppler ultrasonography) in women undergoing ART could predict endometrial receptivity and ICSI outcome. Key words: Uterine blood flow, color Doppler sonography, uterine receptivity. |
