PRELIMINARY EVALUATION OF BLASTOCYST TRANSFER OUTCOMES FOLLOWING TWO BIOPSY METHODS: MR ATHUR 2005 AND CAPALBO 2014
Main Article Content
Abstract
Objectives: To compare the clinical outcomes of blastocyst transfers following two biopsy methods: MR Athur 2005 and Capalbo 2014. Methods: A cross-sectional descriptive study was conducted on 172 blastocysts biopsied at 16A Ha Dong General Hospital between 2023 and 2024. Results: A total of 172 blastocysts were included and divided into two groups based on the biopsy method used: Group 1 included 105 blastocysts (61%) biopsied using the MR Athur 2005 method, and Group 2 included 67 blastocysts (39%) biopsied using the Capalbo 2014 method. Good-quality blastocysts accounted for over 50% in both groups. The proportion of average-quality embryos was low (< 1/4 in both groups). No statistically significant differences were found between the two groups in terms of embryo quality distribution (p = 0.2), implantation rate (53.3% vs. 44.8%, p = 0.2), clinical pregnancy rate (48.6% vs. 44.8%, p = 0.6), or live birth rate (47.6% vs. 36.4%, p = 0.1). Conclusion: The MR Athur 2005 and Capalbo 2014 biopsy techniques yield comparable outcomes in terms of embryo quality, implantation, clinical pregnancy, and survival rates.
