Preimplantation genetic testing for aneuploidy in uterus transplant patients
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.

Preimplantation Genetic Testing for Single Gene Conditions and Aneuploidy
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

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

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 ...

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 (

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]
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.
