Preimplantation genetic testing for aneuploidy (PGT-A)—a single-center experience

Journal of Assisted Reproduction and Genetics, 2022
The aim of this study was to determine the prevalence and nature of human embryonic aneuploidy based on the preimplantation genetic testing for aneuploidy (PGT-A), the distribution of aneuploidy across the individual chromosomes, and their relationship to maternal age.This is a retrospective cohort study conducted at a single center. The study includes

Ugeskrift for laeger, 2020
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 and biopsy of cleavage stage embryos in the 2000s was a disappointment, as studies revealed a ...

The evolution of preimplantation genetic testing for aneuploidy

Reproductive BioMedicine Online, 2019
Abnormal chromosome number or aneuploidy has been recognised as a major contributor to implantation and pregnancy failure and miscarriage since the earliest years of IVF following the birth of Louise Brown forty years ago. Already in 1986, for example, Angell and colleagues, reported "Evidence was found of nondisjunction, resulting in trisomy, monosomy

Preimplantation Genetic Testing for Aneuploidy in Unexplained Recurrent Pregnancy Loss: A Systematic Review and Meta-Analysis

Fertility and Sterility
Importance: Preimplantation genetic testing for aneuploidy (PGT-A) to deselect aneuploid embryos in assisted reproductive technology (ART) treatment cycles may hold promise by augmenting pregnancy rates per transfer and reducing pregnancy loss rates for ...

A Review of Cost-Effectiveness of Preimplantation Genetic Testing for Aneuploidy

Obstetrical & Gynecological Survey
Importance Preimplantation genetic testing for aneuploidy (PGT-A) is an important focus area of reproductive medicine because of its potential to improve the odds of a live birth from in vitro fertilization (IVF) treatment.

The use of preimplantation genetic testing for aneuploidy: a committee opinion

Fertility and Sterility
The use of preimplantation genetic testing for aneuploidy (PGT-A) in the United States has been increasing steadily. Moreover, the underlying technology used for 24-chromosome analysis continues to evolve rapidly. The value of PGT-A as a routine screening test for all patients undergoing in vitro fertilization has not been demonstrated.
