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 (

Mosaicism in preimplantation human embryos

Интегративная физиология, 2020
Since the very first publications on preimplantation genetic testing, researchers have faced a serious problem — a high mosaicism level in the preimplantation human embryos obtained by means of in vitro fertilization cycles.

Non-invasive preimplantation genetic testing for conventional IVF blastocysts

Journal of Translational Medicine, 2022
Background Previous studies suggested that non-invasive preimplantation genetic testing (niPGT) for intracytoplasmic sperm injection (ICSI) blastocysts can be used to identify chromosomal ploidy and chromosomal abnormalities.

Mosaic results after preimplantation genetic testing for aneuploidy may be accompanied by changes in global gene expression

Frontiers in Molecular Biosciences, 2023
Aneuploidy in preimplantation embryos is a major cause of human reproductive failure. Unlike uniformly aneuploid embryos, embryos diagnosed as diploid-aneuploid mosaics after preimplantation genetic testing for aneuploidy (PGT-A) can develop into healthy

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
