Mục tiêu chính của nghiên cứu này là đánh giá kết quả chuyển phôi được xếp loại phôi tốt ở giai đoạn phôi phân chia (ngày 3) và giai đoạn phôi nang (ngày 5) bằng phương pháp nghiên cứu hồi cứu dựa trên các tiêu chí về chất lượng phôi chuyển, kết quả beta HCG sau chuyển phôi, tỷ lệ thai lâm sàng, thai sinh hóa, thai diễn tiến. | TNU Journal of Science and Technology 227 05 308 - 317 THE RESULT IN BLASTOCYST AND CLEAVAGE-STAGE EMBRYO TRANSFER IN ASSITED REPRODUCTIVE TECHNOLOGY Hua Minh Tuan1 Duong Thi Nhan1 Le Thi Thanh Huong2 Ha Hai Bang1 Nguyen Phu Hung2 1A Thai Nguyen Hospital 2TNU - University of Sciences ARTICLE INFO ABSTRACT Received 15 02 2022 Selecting the high developmental potential embryos to transfer and achieving a healthy live birth is the goal of assisted reproduction. At Revised 29 4 2022 other Assisted Reproductive Centers and at the Department of assisted Published 29 4 2022 reproductive technology - A Thai Nguyen hospital day 3 and day 5 embryo transfers are still carried out in parallel and depend on the KEYWORDS characteristics of each patient. The objective of this study was to evaluate the result of embryo transfer which was good at the cleavage Embryo transfer embryo stage day 3 and blastocyst stage day 5 with using a In vitro fertilization retrospective study method based on the criteria of embryo transfer quality beta HCG results after embryo transfer clinical pregnancy rate Fresh transfer biochemical pregnancy progressed pregnancy. Our study showed that Cleaveage embryo transfer the rate of beta positive is the rate of a clinical pregnancy is Blastocyst embryotransfer the rate of ongoing pregnancy is . In addition the rate of Frozen-thawed embryo transfer ongoing pregnancy was significantly lower in the group of patients undergoing day 3 embryo transfer compared with day 5 embryo transfer vs but the rate of multiple pregnancies at day 5 embryo transfer was higher than that of day 3 embryo transfer vs . Curently embryo transfer at blastocyst stage has an advantage over cleavage embryo transfer which was evaluated in our study.
