Aneuploidy in the human blastocyst.
Published 2011“…Here we discuss the latest data from the comprehensive cytogenetic analysis of blastocysts. These findings indicate that the majority of selection against chromosome abnormalities does not occur until the time of implantation or shortly after, with aneuploidy typically affecting more than 50% of blastocysts. …”

Why Euploid Blastocysts Fail
Published 2022-09-01“…Preimplantation genetic testing for aneuploidy improves implantation and reduces miscarriage rates, but still about 30 to 35% of euploid blastocysts fail to implant and 10 to 13% of pregnancies following euploid blastocyst transfer miscarry. …”

Theoretical exploration of blastocyst morphogenesis.
Published 2009“…A theoretical exploration of cell distribution on the mouse blastocyst is conducted. A model ball of cells represents the morula which develops into a 32-cell model blastocyst that is enclosed in a spherical surface with a hemispherical cavity at one end. …”

#66 : Degree of Re-Expansion of Biopsied Blastocysts at Vitrification Affects the Developmental Competence of Blastocyst After Trophectoderm Biopsy
Published 2023-12-01“…Background and Aims: In recent years, preimplantation genetic testing (PGT) has frequently involved a trophectoderm (TE) biopsy at the blastocyst stage, followed by vitrification. However, the factors influencing the viability of biopsied blastocysts after warming are unknown. …”

Re-Biopsy and Biopsy of Post-vitrified Blastocyst
Published 2023-12-01“…However, such an intervention has limited role with poor quality blastocysts. Pre-caution needs to be exercised with vitrified-warmed embryos as the trophectoderm tissue gets very stick at biopsy and there is a chance of complete embryo hatching from zona-pellucida if excessive pressure is applied in the biopsy pipette. …”
