| Abstract | AIM: An appropriate endometrial condition and vascular supply are usually considered essential for implantation of an embryo. This study was performed to assess the role of endometrial and uterine vascularity status measurement in predicting pregnancy outcome during frozen-thawed embryo transfer cycles. MATERIAL AND METHODS: A total of 70 infertile women were recruited with controlled ovarian stimulation followed by oocyte retrieval. After in vitro fertilization or intracytoplasmic sperm injection, embryos were cultured to blastocysts and blastocysts with good quality were selected for cryopreservation. After endometrial preparation, vitrified blastocysts were thawed and assisted hatching by zona dissection was performed. On the day of embryo transfer, endometrial thickness (EMT), resistance index (RI) and pulsatility index (PI) of sub-endometrial artery (SEA) and uterine artery (UA) were obtained by transvaginal sonography. The women were divided into the pregnant and non-pregnant groups, and these variables were compared between the two groups. RESULTS: Patients' general demographic characteristics were not statistically different between the pregnant and non-pregnant groups. The overall implantation rate, clinical pregnancy rate, and ongoing pregnancy rate were 31.1%, 41.4% and 28.6%, respectively. Twenty-nine patients who conceived had average EMT, RI of SEA, PI of SEA, RI of UA, and PI of UA values of 9.15 mm, 0.91, 2.42, 0.95, and 3.37, respectively. Forty-one patients who did not conceive had average EMT, RI of SEA, PI of SEA, RI of UA, and PI of UA values of 9.31 mm, 1.01, 2.56, 0.94, and 3.00, respectively. In the two groups, none of the variables was statistically different (P > 0.05). CONCLUSIONS: EMT and blood flow index of endometrium and uterus measured by transvaginal sonography are not an effective predictor of pregnancy outcome in frozen-thawed embryo transfer cycles. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
