Embryo selection is a crucial step in assisted reproductive treatment (ART), specifically in IVF (in vitro fertilization), identifying the most viable embryos for transfer through careful selection ...
The test deemed each of the Petersens’ five embryos abnormal, meaning their clinic—like many in the industry—refused to use any of them. “It was like, ‘Well, better luck next time.
Reciprocal translocations (RecT) and Robertsonian translocations (RobT) are among the most common chromosomal abnormalities that cause infertility and birth defects. Preimplantation genetic testing ...
The presence of an abnormal number of chromosomes in embryos is a major cause of impaired embryo development. But mosaic embryos, comprising both genetically normal and abnormal cells, can result ...
Rajiv McCoy, an assistant professor in the Department of Biology, and his collaborators at London Women’s Clinic in the U.K. discovered a strong correlation between chromosome abnormalities, embryo ...

Purpose: We aimed to analyze the pregnancy outcomes and perinatal follow-up of mosaic embryo transfer in the preimplantation genetic testing (PGT) cycles. Method: We retrospectively selected 27 mosaic ...
An artificial intelligence algorithm can determine non-invasively, with about 70 percent accuracy, if an in vitro fertilized embryo has a normal or abnormal number of chromosomes, according to a ...

Genetically abnormal embryos can be discarded or used for research after consent from a couple. PGT centers are under Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act of 1994 which ...
Embryo culture induces low birth weight, abnormal placental morphology, and lower levels of DNA methylation in placentas in a mouse model of ART. Whether preimplantation embryos at specific stages of ...
