Aneuploidy in the human blastocyst. by Fragouli, E, Wells, D

“…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 by David KEEFE

“…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. by Shipley, R, Bonsall, M, Allwright, D, Graham, C

“…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 by Tetsuya Miki, Kenji Ezoe, Mariko Aruga, Mika Narisawa, Tadashi Okimura, Keiichi Kato

“…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 by Krishna Mantravadi

“…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. …”

Mapping of meiotic recombination in human preimplantation blastocysts by Yuanlin Ma, Jing Wang, Rong Li, Chenhui Ding, Yan Xu, Canquan Zhou, Yanwen Xu

“…In this study, 164 and 240 couples who underwent preimplantation genetic testing for monogenic diseases or segmental rearrangement were included in the analysis. Blastocysts and probands from couples who underwent preimplantation genetic testing for monogenic diseases by single nucleotide polymorphism array were included for recombination analysis. …”
