Journal of Translational Medicine, 2022 Background This study aimed to analyze the clinical outcomes of blastocyst which undergo the preimplantation genetic testing (PGT) transplantation from frozen-thawed D5 and D6. In addition, the effect of blastocyst grade on clinical and neonatal outcomes

Scientific Reports, 2023 Blastocyst selection is primarily based on morphological scoring systems and morphokinetic data. These methods involve subjective grading and time-consuming techniques. Artificial intelligence allows for objective and quick blastocyst selection.

Fertility & Reproduction, 2023 Background and aims: Is there any chance for an embryo having one of these types of abnormal cleavage including direct cleavage (DC), reverse cleavage (RC) or multinucleation can result in a healthy baby?

Journal of Ovarian Research, 2021 Background Laser-assisted hatching (LAH) has been widely applied to facilitate blastocyst hatching in IVF-ET treatment, however, the effect of LAH on subsequent development and clinical outcomes of the lower grade cleavage stage embryos (LGCE) remains ...

p38 MAPK regulates cavitation and tight junction function in the mouse blastocyst. [PDF]
PLoS ONE, 2013 Blastocyst formation is essential for implantation and maintenance of pregnancy and is dependent on the expression and coordinated function of a series of proteins involved in establishing and maintaining the trans-trophectoderm ion gradient that enables

Morphogenesis of the mammalian blastocyst [PDF]
Molecular and Cellular Endocrinology, 2008 The first 4 days of mouse pre-implantation development are characterized by a period of segmentation, including morphogenetic events that are required for the divergence of embryonic and extra-embryonic lineages. These extra-embryonic tissues are essential for the implantation into the maternal uterus and for the development of the foetus.

Estrogen-dependent uterine secretion of osteopontin activates blastocyst adhesion competence. [PDF]
PLoS ONE, 2012 Embryo implantation is a highly orchestrated process that involves blastocyst-uterine interactions. This process is confined to a defined interval during gestation referred to as the "window of embryo implantation receptivity".

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]
, 2014 Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Frozen blastocysts: Assessing the importance of day 5/day 6 blastocysts or blastocyst quality
Experimental and Therapeutic Medicine, 2022 The aim of the present study was to analyze the high-quality blastocyst (HB) rate in all embryo frozen cycles and investigate the pregnancy outcomes for day 5/day 6 (D5/D6) blastocysts with respect to the blastocyst quality in programmed single vitrified-warmed blastocyst transfer (SVBT).

Image Segmentation of Zona-Ablated Human Blastocysts [PDF]
IEEE 13th International Conference on Nano/Molecular Medicine &
Engineering (NANOMED), Gwangju, Korea (South), 2019, pp. 208-213, 2020 Automating human preimplantation embryo grading offers the potential for higher success rates with in vitro fertilization (IVF) by providing new quantitative and objective measures of embryo quality. Current IVF procedures typically use only qualitative manual grading, which is limited in the identification of genetically abnormal embryos.
