Assessment of aneuploidy concordance between clinical trophectoderm biopsy and blastocyst
Human Reproduction, 2018 STUDY QUESTION Is a clinical trophectoderm (TE) biopsy a suitable predictor of chromosomal aneuploidy in blastocysts? SUMMARY ANSWER In the analyzed group of blastocysts, a clinical TE biopsy was an excellent representative of blastocyst karyotype in ...

Reproductive Biology and Endocrinology, 2019 Background Blastomere movement (BMov) occurs after the first cell division in human embryos. This movement has been suggested as a prognostic parameter for pregnancy outcome prediction following cleavage-stage embryo transfer. However, the effect of BMov

How to make a blastocyst [PDF]
Biochemistry and Cell Biology, 1992 Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the ...

Frontiers in Cell and Developmental Biology, 2021 Preimplantation genetic testing for aneuploidy (PGT-A) is widely used to select embryos having normal ploidy for transfer, but they require an invasive embryo biopsy procedure that may cause harm to the embryos and offspring.

Journal of Human Reproductive Sciences, 2013 Objectives: The literature regarding clinical outcomes following day 5/6 vitrified warmed blastocysts transfer has been conflicting. We decided to evaluate and compare the clinical outcomes following vitrified warmed day 5/6 blastocyst transfer using a ...

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]
, 2020 In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.
