Inter-group comparison analyses of primary conditions, pregnancy outcomes and neonatal outcomes were then performed. <h4>Results</h4> Group A had the highest embryo implantation rate (67.38%), significantly different from the implantaPeerJhttps://www.ebi.ac.uk/biostudies/studies/S-EPMC9703987biostudies-literatureComparison of frozen-thawed embryo transfer strategies for the treatment of infertility in young women: a retrospective studyPMC9703987C20170007Ma LLu XFu YZhao JWu YfalseComparison of frozen-thawed embryo transfer strategies for the treatment of infertility in young women: a retrospective study<h4>Objective</h4> To investigate transfer strategies in the frozen-thawed embryo transfer (FET) cycle. <h4>Methods</h4> The clinical data of 1,652 FET patients were divided into five groups according to the number and quality of the transferred blastocyst: high-quality single blastocyst group (group A, n = 558), high-quality plus poor-quality double blastocyst group (group B, n = 435), poor-quality double blastocyst group (group C, n = 241), high-quality double blastocyst group (group D, n = 298), and poor-quality single blastocyst group (group E, n = 120).
