Single-cell sequencing shows mosaic aneuploidy in most human embryos
Mammalian preimplantation embryos often contain chromosomal defects that arose in the first divisions after fertilization and affect a subpopulation of cells — an event known as mosaic aneuploidy. In this issue of the JCI, Chavli et al.

Preimplantation Genetic Screening in In Vitro Fertilization (IVF): A Comprehensive Review of Ethical, Clinical, and Technological Developments [PDF]
Preimplantation Genetic Testing for Aneuploidy (PGT-A) and Preimplantation Genetic Screening (PGS) have become indispensable tools in In Vitro Fertilization (IVF) to increase pregnancy rates and enhance embryo choice.

ChromInst: a multicentre evaluation of robustness in aneuploidy and structural rearrangement testing
Background Preimplantation genetic testing for aneuploidy and for chromosomal structural rearrangement (PGT-A/-SR) can improve clinical pregnancy rates and live birth rates, and shorten the time to pregnancy.

Births from aneuploid embryos: where is the evidence?
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

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
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.
