A RANDOMIZED CONTROLLED TRIAL COMPARING LIVE BIRTH FROM SINGLE EUPLOID FROZEN BLASTOCYST TRANSFER USING STANDARDIZED TIMING VERSUS TIMING BY ENDOMETRIAL RECEPTIVITY ANALYSIS

To compare live birth (LB) from single euploid frozen blastocyst transfer (FBT) according to Endometrial Receptivity Analysis (ERA) vs. standardized timing This was a single-center, assessor-blind, parallel-group RCT with 1:1 randomization. Recurrent pregnancy loss and recurrent implantation failure were excluded. All subjects underwent IVF-ICSI, PGTA, and ERA; those with PGTA-normal blastocyst(s) and an informative ERA were randomized.
