Preimplantation Genetic Testing

Abstract Preimplantation genetic testing (PGT) allows recognition of a genetically abnormal embryo in the laboratory, and enables the choice, in principle, of selecting a normal embryo for transfer to the uterus. The methodologies are outlined in this chapter, noting that blastocyst biopsy is the preferred time/stage, and that the ...

Preimplantation Genetic Testing

Revue medicale suisse, 2019
Preimplantation genetic testing avoids the transmission of monogenic diseases or structural chromosome abnormality to the offspring in fertile couples. Furthermore, it allows screening for aneuploidies (PGT-A, Preimplantation genetic testing for aneuploidy), with the aim of selecting one euploid embryo before transfer in infertile couples undergoing in

Preimplantation genetic testing

BMJ, 2012
#### Summary points Preimplantation genetic (PG) testing is the practice of obtaining a cellular biopsy sample from a developing human oocyte or embryo, acquired via a cycle of in vitro fertilisation (IVF); evaluating the genetic composition of this sample; and using this information to determine which embryos will be optimal for subsequent uterine ...

Preimplantation genetic testing in assisted reproduction

Minerva Obstetrics and Gynecology, 2023
In the last years technologies have been developed that allow obtaining genetic information in less time and at lower cost, revolutionizing the genetic diagnosis in reproductive medicine, with availability of genetic tests from conception. High throughput sequencing analyses have increased the ability to detect embryos with genetic diseases, which has ...

Child health after preimplantation genetic testing

Reproductive BioMedicine Online, 2021
Despite the increasing use of preimplantation genetic testing (PGT) for aneuploidy and monogenic diseases, for children conceived using PGT there is limited follow-up beyond 2 years of age. This study examined the health, well-being and development of school-aged children (5-8 years old) conceived following PGT.Retrospective cohort study of children ...

Preimplantation genetic tests

2008
Abstract Preimplantation genetic diagnosis (PGD) is a test developed to help couples who are at risk of passing on an inherited disease to have a healthy family. It is carried out on embryos and needs IVF first (see Chapter 14). These couples have normal fertility and would conceive naturally, but choose to undergo IVF in order to have ...

Clinical applications of preimplantation genetic testing

BMJ, 2015
Genetic diagnostic technologies are rapidly changing the way medicine is practiced. Preimplantation genetic testing is a well established application of genetic testing within the context of in vitro fertilization cycles. It involves obtaining a cell(s) from a developing embryo in culture, which is then subjected to genetic diagnostic analysis; the ...
