In Vitro Fertilization and Embryo Culture Strongly Impact the Placental Transcriptome in the Mouse Model

TLDR
For the first time, in vitro fertilization associated with embryo culture strongly modify the placental expression profile, long after embryo manipulations, meaning that the stress of artificial environment is memorized after implantation.
Abstract
Background Assisted Reproductive Technologies (ART) are increasingly used in humans; however, their impact is now questioned. At blastocyst stage, the trophectoderm is directly in contact with an artificial medium environment, which can impact placental development. This study was designed to carry out an in-depth analysis of the placental transcriptome after ART in mice.

Assisted reproductive technology.

TL;DR: Assisted reproductive technology (ART) is the technology used to achieve pregnancy in procedures such as fertility medication, artificial insemination, in vitro fertilization and surrogacy.

Epigenetics and the placenta

TL;DR: Epigenetic regulation of the placenta evolves during preimplantation development and further gestation and appears to be involved in the pathogenesis of pre-eclampsia and GTD.

Expert consensus document: Clinical and molecular diagnosis, screening and management of Beckwith-Wiedemann syndrome: an international consensus statement.

TL;DR: An international consensus group agreed upon 72 recommendations for the clinical and molecular diagnosis and management of Beckwith–Wiedemann syndrome, including comprehensive protocols for the molecular investigation, care and treatment of patients from the prenatal period to adulthood.

Infertility and reproductive disorders: impact of hormonal and inflammatory mechanisms on pregnancy outcome

TL;DR: There is a real need for development of evidence-based recommendations about clinical management and specific obstetric care pathways for the introduction of prompt preventative care measures.

Further evidence that culture media affect perinatal outcome: findings after transfer of fresh and cryopreserved embryos

TL;DR: The hypothesis that in vitro culture of embryos during the first few days of preimplantation development affects perinatal outcome of IVF singletons and twins is supported and might be an important factor explaining the poorer perinnatal outcome after assisted reproduction technology (ART).
