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.
