“…Our results are in agreement with Applebaum [2]. In the studies conducted by Chien et al [13] and Maugey-Laulon et al [15], absent endometrial vascularization was associated with significantly lower pregnancy rate. It has been postulated that a better endometrial and subendometrial vascularity can lead to a better placental development during pregnancy which is associated with a lower risk of miscarriage and a higher chance of live birth following ART [10].…”

About the Author AbstractPurpose To detect whether ultrasonographic parameters and Doppler analysis of uterine blood flow can be of value in the prediction of endometrial receptivity in infertile female patients undergoing embryo transfer. Methods In this study, a total of 200 women with primary infertility undergoing embryo transfer were analyzed. Transvaginal ultrasonography was done on the 10th day of the menstrual cycle. To assess the uterine receptivity, we analyzed all the ultrasonographic and Doppler parameters. The slightly modified version of Applebaum Uterine Scoring System was used. This uterine scoring system included all the following parameters: endometrial thickness, endometrial morphology, endometrial blood flow within zone 3, myometrial echogenecity, uterine artery pulsatility index (PI), end diastolic blood flow, and myometrial blood flow internal to the arcuate vessels seen on gray-scale examination. Results The pregnancy rates were higher in women with thick, distinct five-line endometrium and multifocal endometrial vascularity within zone 3. Absent endometrial flow, despite highest values for the other parameters, was associated with no conception. In our study, no pregnancy occurred with uterine PI values of more than 2.8. Absence or reversal of end diastolic blood flow was associated with no conception. A maximum score of 20 was associated with the pregnancy rate of 97.4 %, whereas scores of 13 or less resulted in no pregnancies. 123Conclusion Uterine scoring system will help to perform embryo transfers in only favorable uteri and postpone or cancel those cycles in which poor uterine score is demonstrated.

“…This suggests that the endometrium may exert effects on pregnancy rates. It may be speculated that the reduction in endometrial thickness is due to a reduction of endometrial and subendometrial blood flow [22][23][24].…”

“…Poor uterine perfusion can be one of the important reasons behind the cases of unexplained infertility [8]. Chien et al observed a significantly higher pregnancy and implantation rates in patients with increased vascularity as compared to the patients in which there was no detectable blood flow on Doppler [12]. Similar observation was made in the present study, where the total 5 patients who subsequently conceived, 4 (30.76%) belonged to the patient group of 13 patients with good vascularity i.e.…”

Background: A good blood flow towards the endometrium is an essential prerequisite for its development and differentiation, for the implantation of blastocyst and continuation of pregnancy. Diminished endometrial perfusion may be the one of the important reason behind the patients with unexplained infertility. The present study was carried out to estimate the cut-off of microvascular density determinative of good endometrial receptivity.
