Correlating the Endometrial Thickness and Assisted Reproductive Technology Outcome in Women Who Underwent Frozen-thawed Embryo Transfer after Endometrial Preparation Using Hormone Replacement: A Retrospective Cohort Study
Abstract
Aim and background: Synchronized endometrial thickness and embryonic development is a requisite for successful assisted reproductive technology (ART) outcome.This study aimed to correlate endometrial thickness on the day of progesterone initiation with ART outcomes in women undergoing frozen-thawed transfer of good quality cleavage-stage (day 3) and blastocyst-stage (day 5) embryos after hormone-replaced endometrial preparation. Materials and methods:This retrospective analysis included records of 252 patients who satisfied the inclusion criteria.The cohort was divided into day 3 frozen-thawed embryo transfer (FET) cycles (n = 171) and day 5 FET cycles (n = 81).Within each category, patients were grouped by endometrial thickness: Group I (
