Correlation study of male semen parameters and embryo aneuploidy in preimplantation genetic testing for aneuploidy

open access: yesFrontiers in Endocrinology, 2023
ObjectiveThe purpose of this study was to evaluate the influence of abnormal semen parameters on embryo aneuploidy based on single nucleotide polymorphism microarray (SNP array).MethodsA total of 464 blastocysts from 103 PGT-A cycles were analyzed.

Advances in Preimplantation Genetic Testing for Monogenic Disease and Aneuploidy

open access: yesAnnual Review of Genomics and Human Genetics, 2017
Genetic testing of preimplantation embryos promises to prevent monogenic disease in children born to at-risk couples, the transfer of unbalanced embryos to patients carrying a balanced translocation, and the use of aneuploid embryos created during in vitro fertilization.

Performance of preimplantation genetic testing for aneuploidy in IVF cycles for patients with advanced maternal age, repeat implantation failure, and idiopathic recurrent miscarriage

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2019
Objective: The primary objective of this study was to investigate whether preimplantation genetic testing for aneuploidy (PGT-A) of blastocysts through array comparative genomic hybridization (aCGH) improves live birth rates (LBR) in IVF cycles for ...

Changes in sequencing technology used for preimplantation genetic testing for aneuploidy. [PDF]

open access: yesJ Assist Reprod Genet
Abstract The continued development of assisted reproductive technologies has aimed to improve pregnancy outcomes through screening methods for the identification of embryos with monogenic disorders, chromosomal aneuploidy or structural abnormalities.

Next generation sequencing for preimplantation genetic testing of blastocysts aneuploidies in women of different ages [PDF]

open access: yesAnnals of Agricultural and Environmental Medicine, 2015
Most of the current preimplantation genetic screening of aneuploidies tests are based on the low quality and low density comparative genomic hybridization arrays. The results are based on fewer than 2,700 probes.

Retrospective cohort study of preimplantation genetic testing for aneuploidy with comprehensive chromosome screening versus nonpreimplantation genetic testing in normal karyotype, secondary infertility patients with recurrent pregnancy loss

open access: yesReproductive and Developmental Medicine, 2019
Objective: To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) with comprehensive chromosome screening increases live birth rate (LBR) in normal karyotype couples with recurrent pregnancy loss (RPL). Methods: A retrospective cohort

Single-cell sequencing shows mosaic aneuploidy in most human embryos

open access: yesThe Journal of Clinical Investigation
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.

Non-invasive preimplantation genetic testing for aneuploidies: an update [PDF]

open access: yesReproductive BioMedicine Online, 2022
Aneuploidy is common among preimplantation human embryos used in assisted reproductive technology. Because abnormal chromosome number can negatively affect reproductive outcome, in-vitro-fertilized embryos routinely undergo aneuploidy testing before transfer into the uterus.

Noninvasive preimplantation genetic testing for aneuploidy

open access: yesBulletin of Russian State Medical University, 2023
To date the world community is actively working to optimize the approaches to determining chromosomal abnormalities in embryos. The study was aimed to assess the possibility of using noninvasive preimplantation genetic testing for aneuploidy (niPGT-A) through analysis of cell-free DNA in spent culture medium (SCM).
