[Preimplantation genetic testing for aneuploidy].

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 ...

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 ...

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

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.

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.

Preimplantation genetic testing for aneuploidy (PGT‐A): The biology, the technology and the clinical outcomes

Australian and New Zealand Journal of Obstetrics and Gynaecology, 2019
Preimplantation genetic testing for aneuploidy (PGT‐A) seeks to identify preimplantation embryos with a normal chromosome complement (euploid) during in vitro fertilisation (IVF). By sifting out embryos with abnormal chromosome numbers (aneuploid), PGT‐A should theoretically improve pregnancy success. However, earlier versions of PGT‐A were ineffective,
