Background In assisted reproductive treatments, embryos remaining after fresh embryo
transfer are usually selected for cryopreservation based on traditional morphology …

OBJECTIVE: To assess the benefit of selecting blastocysts for cryotransfer based upon prior
comparative genomic hybridization (CGH) karyotyping of blastomeres derived from their …

Background Single embryo transfer (SET) remains underutilized as a strategy to reduce
multiple gestation risk in IVF, and its overall lower pregnancy rate underscores the need for …

Purpose To determine which blastocyst assessment variables predict clinical implantations
in single blastocyst frozen embryo transfers (FET) of freeze-only-IVF cycles, following …

Objective To determine whether blastocyst grading can predict pregnancy outcomes in the
frozen-thawed embryo transfer (FET) of euploid blastocysts. Design Retrospective cohort …

Trophectoderm biopsy with comprehensive chromosome screening (CCS) has been shown
to increase implantation and pregnancy rates. Some patients desire CCS on previously …

Purpose Preimplantation genetic screening (PGS) and diagnosis (PGD) with euploid
embryo transfer is associated with improved implantation and live birth rates as compared to …

BACKGROUND: The purpose of this study was to evaluate the respective influences of
blastomere survival and resumption of mitosis on the outcome of frozen–thawed embryos …

Purpose Whether there are differences in the pregnancy outcomes of blastocysts
cryopreserved during different developmental stages remains under debate because the …

Surplus embryos available for cryopreservation in fresh cycles are considered as having
good potential for future use. However, the optimal stage of embryo cryopreservation …
