The status of preimplantation genetic testing for aneuploidy (PGT-A) – A critical appraisal

Therapeutic Advances in Reproductive Health
Preimplantation genetic testing for aneuploidy (PGT-A) relies on extended embryo culture and trophectoderm biopsy at the blastocyst stage. Its utility is thus dependent on obtaining an adequate embryo yield and blastulation rates. i.e. before embryos can

Births from aneuploid embryos: where is the evidence?

BMJ Connections Clinical Genetics and Genomics
Background Preimplantation genetic testing for aneuploidy (PGT-A) is used principally to identify embryos with whole chromosome aneuploidy, which are generally considered non-viable. Reports of healthy live births following transfer of embryos classified

Investigating developmental characteristics of biopsied blastocysts stratified by mitochondrial copy numbers using time-lapse monitoring

Reproductive Biology and Endocrinology
Background For in vitro fertilization (IVF), mitochondrial DNA (mtDNA) levels in the trophectodermal (TE) cells of biopsied blastocysts have been suggested to be associated with the cells’ developmental potential. However, scholars have reached differing

Preimplantation genetic diagnosis

Zdravniški Vestnik, 2013
Backg round: Preimplantation genetic diagnosis (PGD) is used to analyze embryos before their transfer into uterus. It is suitable for a group of patients who are at a substantial risk of conceiving a pregnancy affected by a known genetic defect.

Predictive factors of aneuploidy in infertile patients undergoing IVF: a retrospective analysis in a private IVF practice

Middle East Fertility Society Journal
Background PGT-A has become an important part of IVF treatments. Despite its increased use, there are contradicting results on its role in improving reproductive outcomes of ART cycles.
