Embryo response to aneuploidy through self-correction mechanism: a literature review

Middle East Fertility Society Journal
Background Meiotic and mitotic errors often lead to aneuploidy and mosaicism. In this context, the self-correction mechanism enables the embryo to preferentially retain and preserve euploid cells through processes such as apoptosis, necrosis, or ...

Whole genome amplification for PGD and PND; molecular and a-CGH diagnosis

, 2009
Whole genome amplification amplifies the entire genome in a few hours from samples of minimal DNA quantities, even from single cells. This may have many applications, especially in prenatal diagnosis, PGD and PGS. The hypothesis for chapter 3 was: Can

Preimplantation genetic testing for aneuploidy

, 2019
This review summarises the current knowledge on preimplantation genetic testing for aneuploidy (PGT-A). Selection and transfer of euploid embryos aim to improve live birth rate (LBR) per embryo transfer, but fluorescence in situ hybridisation-based PGT-A

Preimplantation Genetic Screening in In Vitro Fertilization (IVF): A Comprehensive Review of Ethical, Clinical, and Technological Developments [PDF]

Journal of Medical and Life Science
Preimplantation Genetic Testing for Aneuploidy (PGT-A) and Preimplantation Genetic Screening (PGS) have become indispensable tools in In Vitro Fertilization (IVF) to increase pregnancy rates and enhance embryo choice.

Clinical impact of preimplantation genetic testing for aneuploidy in patients with recurrent implantation failure in Vitro fertilization cycles. A retrospective study.

, 2022
Hypothesis and aims We hypothesize that adverse reproductive history such as infertile couple with RIF associated with low embryo euploidy rate and hence poor outcome in IVF treatment compared to infertile couples with non-RIF and fertile couples with a ...

ChromInst: a multicentre evaluation of robustness in aneuploidy and structural rearrangement testing

Journal of Translational Medicine
Background Preimplantation genetic testing for aneuploidy and for chromosomal structural rearrangement (PGT-A/-SR) can improve clinical pregnancy rates and live birth rates, and shorten the time to pregnancy.

Second-generation preimplantation genetic testing for aneuploidy in assisted reproduction: a SWOT analysis

Second-generation preimplantation genetic testing for aneuploidy (PGT-A 2.0) in patients with an unfavourable reproductive and IVF prognosis is becoming common practice, with the aim of improving reproductive outcomes.
