Are endometrial parameters by three-dimensional ultrasound and power Doppler angiography related to in vitro fertilization/embryo transfer outcome?

Predictive value of subendometrial - endometrial blood flow assessment by transvaginal 3D power doppler on the day of HCG on clinical outcome of IVF cycles

“…15,18 This is based on the reports of increased impedance of uterine arteries after HCG Injection and its influence on the predictive value of Ultrasonography. 19 So, we selected the day of HCG for 3D-Power Doppler assessment in our study.…”

Three-dimensional ultrasound as a predictor of pregnancy in patients undergoing ART

“…a) The first studies reported a good correlation between endometrial volume and pregnancy (31)(32)(33). Although it has been shown that the endometrium must attain at least 2.0-2.5 ml to achieve a pregnancy, recent studies did not confirm the relation between endometrial volume and pregnancy outcome (33)(34)(35)(36)(37). In our study, the area under the receiver operating characteristic (ROC) curve was statistically significant for endometrial volume when no grade 1 embryos or only one were transferred but not significant when two or three grade 1 embryos were transferred (34).…”

“…Successful implantation depends on the interaction between the blastocyst and the endometrium. Thickness of endometrium and a good blood supply are considered to favour pregnancy (7)(8)(9). Increased endometrial and subendometrial vascularity have been found to be higher in patients with live births following Assisted Reproductive Technology (ART) than in those who have suffered a miscarriage (10).…”

Prediction of pregnancy in artificial reproductive techniques through evaluation of thickness, morphology and vascularity of endometrium

“…A good blood supply to the endometrium is an essential requirement for implantation and assessment of endometrial blood flow in IVF treatment has attracted a lot of attention in recent years. 1 Doppler study of uterine arteries does not reflect the actual blood flow to the endometrium. Endometrial and sub endometrial blood flows can be more objectively and reliably measured with three-dimensional power Doppler ultrasound.…”
