Đánh giá mối liên quan giữa hình thái phôi nang với tỉ lệ làm tổ ở nhóm bệnh nhân làm thụ tinh ống nghiệm chuyển đơn phôi nang đông lạnh

Evaluating the association between blastocyst morphology and implantation rate in single blastocyst transfer of invitro fertilization patients. Subjects and methods: In this cross-sectional study performed at Center of IVF and Tissue engineering - Hanoi Medical University Hospital, the blastocyst morphology and implantaion outcomes of 384 single vitrified embryo transfer cycles were evaluated. Results: The overall implantation rate was 54.9%. The implantation rates of very good and good morphological blastocyst groups (72.2% and 61.8%) were significantly higher than that of average morphological group (54.4%) and poor morphological group (25.3%). All 3 criteria of blastocyst morphology (expansion, inner cell mass and trophectoderm) associated with implantation rate. However, after performing logistic regression, adjusting for maternal age, times of embryo transfers, blastocyst expansion, only quality of inner cell mass and trophectoderm were significantlly associated with implantation outcome after single vitrified blastocyst transfer.
