Preimplantation genetic diagnosis
Nature Reviews Genetics, 2002Preimplantation genetic diagnosis (PGD) is an evolving technique that provides a practical alternative to prenatal diagnosis and termination of pregnancy for couples who are at substantial risk of transmitting a serious genetic disorder to their offspring.

Preimplantation genetic diagnosis
Molecular and Cellular Endocrinology, 2000Preimplantation genetic diagnosis (PGD) includes a variety of techniques that have been developed to detect the transmission to the offspring of genetic diseases or of chromosome abnormalities by couples at risk before a pregnancy is established, to avoid these couples the risk of recurrent abortions and/or of repeated terminations of pregnancy ...

Preimplantation genetic diagnosis is a valuable addition to the repertoire of reproductive medicine because it gives individuals with a documented history of a genetic disorder the opportunity to begin a wanted pregnancy with little or no fear that they are transmitting this disorder to their offspring.

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 ...

Prenatal Diagnosis, 1994
AbstractResearch towards preimplantation diagnosis of genetic disease was initiated in the UK. in the mid 1980s with the aim of helping those couples who would prefer selection to occur at this stage rather than during pregnancy. Following in vitro fertilisation, (IVF), biopsy and removal of 1 or 2 of the totipotent cells from the cleavage stage 3 day ...

Preimplantation testing for phenylketonuria
Fertility and Sterility, 2001To use preimplantation genetic diagnosis to achieve a phenylketonuria-free pregnancy in a couple at 50% risk for producing an affected child.DNA analysis of the first and second polar bodies (PB1 and PB2) obtained from oocytes of a heterozygous mother in IVF-ET, with the goal of identifying and transferring back to the patient the embryos resulting ...

PREIMPLANTATION PRENATAL DIAGNOSIS
Obstetrics and Gynecology Clinics of North America, 1993Preimplantation prenatal diagnosis refers to the application of molecular genetic techniques to the assessment of gametes before conception or to early embryos before implantation. Such techniques could allow couples at significant risk for a variety of known genetic diseases to use assisted reproductive technology in achieving pregnancies that are ...

Updates on preimplantation embryo research
Fertility and Sterility, 2023Preimplantation development is the only stage of human development that can be studied outside the body in real time, as human embryos can be produced by in vitro fertilization and cultured in the laboratory as self-contained structures until the blastocyst stage.

Preimplantation Genetic Screening
2013Chromosome aneuploidy is naturally occurring, typically sporadic and generally leads to non-viable offspring. The use of PGS has the potential to select the best embryos for transfer and reduce the risk of losing a much wanted pregnancy. However there is no high-level clinical evidence from randomized control trials to demonstrate a beneficial effect ...

Preimplantation genetic diagnosis
Current Opinion in Pediatrics, 1994Preimplantation genetic diagnosis now represents an alternative reproductive option for parents at high risk of having offspring affected with certain genetic diseases. Progress in the past year has included increasing reliability in embryo sexing by both polymerase chain reaction and fluorescent in situ hybridization techniques; delivery of babies ...
