Comparison of frozen-thawed embryo transfer strategies for the treatment of infertility in young women: a retrospective study [PDF]

PeerJ, 2022
Objective To investigate transfer strategies in the frozen-thawed embryo transfer (FET) cycle. Methods 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 ...

#176 : The Relationship Between Blastocyst Morphology and PGD Result

Fertility & Reproduction, 2023
Background and Aims: Blastocyst morphology has been clinically assessed during the selection of blastocyst for transfer and cryopreservation, and the morphological grading scheme has gained wide acceptance. Blastocyst grading according to Gardner et al. (

Comparison of clinical outcomes of frozen-thawed D5 and D6 blastocysts undergoing preimplantation genetic testing

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

An artificial intelligence algorithm for automated blastocyst morphometric parameters demonstrates a positive association with implantation potential

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.

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

Laser-assisted hatching in lower grade cleavage stage embryos improves blastocyst formation: results from a retrospective study

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 ...

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".

Pluripotent Stem Cells as a Model for Human Embryogenesis

Cells, 2023
Pluripotent stem cells (PSCs; embryonic stem cells and induced pluripotent stem cells) can recapitulate critical aspects of the early stages of embryonic development; therefore, they became a powerful tool for the in vitro study of molecular mechanisms ...

Placental deficiency of the (pro)renin receptor ((P)RR) reduces placental development and functional capacity

Frontiers in Cell and Developmental Biology, 2023
The (pro)renin receptor ((P)RR; also known as ATP6AP2) is a multifunctional receptor. The (P)RR activates the tissue renin-angiotensin system (RAS) and is also involved in regulating integral intracellular pathways such as V-ATPase and Wnt/β-catenin ...

EFFECT OF MORPHOLOGY AND BLASTOCYST DEVELOPMENT ON THE OUTCOME OF SINGLE-BLASTOCYST TRANSFER IN THE IN VITRO FERTILIZATION PROGRAMME

Zdravniški Vestnik, 2018
Background. Multiple pregnancy can be prevented by an elective single blastocyst transfer. The aim of this prospective study was to evaluate the effect of blastocyst development and morphology on the outcome of single blastocyst transfer. Methods.
