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

Frontiers 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.

Preimplantation Genetic Testing for Single Gene Conditions and Aneuploidy

Fertility & Reproduction, 2023
It is now over 30 years since the first pregnancies and live births following IVF, embryo biopsy and preimplantation genetic testing (PGT) were reported in 1990. Since then, methods for genetic analysis at the single-cell level have evolved alongside the

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 [PDF]

Reproductive 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

Preimplantation genetic testing for aneuploidy in uterus transplant patients

Therapeutic Advances in Reproductive Health, 2021
Uterus transplantation is an emerging treatment for uterine factor infertility. In vitro fertilization with cryopreservation of embryos prior is required before a patient can be listed for transplant.

Implementation of Noninvasive Preimplantation Genetic Testing for Aneuploidy with Spent Blastocyst Medium into Clinical and Laboratory Practice: The First Successful Experience in Taiwan

Fertility & Reproduction, 2023
Noninvasive preimplantation genetic testing for aneuploidy (niPGT-A) using cell-free DNA (cfDNA) present in the spent blastocyst medium (SBM) of human blastocysts has emerged as an alternative for classical preimplantation genetic testing for aneuploidy (

Embryo ploidy status classification through computer-assisted morphology assessmentAJOG MFM at a Glance

AJOG Global Reports, 2023
BACKGROUND: Preimplantation genetic testing for aneuploidy has been proven to be effective in determining the embryo's chromosomal or ploidy status. The test requires a biopsy of embryonic cells on day 3, 5, or 6 from which complete information on the ...

Application of machine learning to predict aneuploidy and mosaicism in embryos from in vitro fertilization cyclesAJOG Global Reports at a Glance

AJOG Global Reports, 2022
BACKGROUND: The factors associated with embryo aneuploidy have been extensively studied. Mostly maternal age and to a lesser extent male factor and ovarian stimulation have been related to the occurrence of chromosomal alterations in the embryo.

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

Reproductive 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.
