Comparison of pregnancy outcomes between 4th day morula and 5th day blastocyst after embryo transfer:a retrospective cohort study

2024-01-15

Abstract excerpt

<h4>Background: </h4> This study was designed to evaluate pregnancy outcomes between morulae transferred on day 4 (D4) and blastocysts transferred on day 5 (D5). Methods From September 2017 to September 2020, 1963 fresh transfer cycles that underwent early follicular phase extra-long protocol for assisted conception in our fertility center were divided into D4 (324 cases) and D5 (1639 cases) groups based on the n...
