A systematic review and meta-analysis: clinical outcomes of recurrent pregnancy failure resulting from preimplantation genetic testing for aneuploidy

Frontiers in Endocrinology, 2023
BackgroundPreimplantation genetic testing for aneuploidy (PGT-A) is an emerging technology that aims to identify euploid embryos for transfer, reducing the risk of embryonic chromosomal abnormalities.

The Expanding Role of Gene Sequencing in Shaping Fetal Therapies: Clinical and Ethical Considerations

Prenatal Diagnosis, EarlyView.
ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.

Does preimplantation genetic testing for aneuploidy improve live birth rate in women diagnosed with recurrent implantation failure: A systematic review and meta‐analysis?

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Preimplantation genetic testing for aneuploidy may improve both live birth rate per embryo transfer and cumulative live birth rate per cycle for women diagnosed with recurrent implantation failure. Abstract Introduction The prevalence of unexplained recurrent implantation failure (RIF) is reported as 2%–15% in the literature.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

Equine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Novel technologies emerging for preimplantation genetic diagnosis and preimplantation genetic testing for aneuploidy

Expert Review of Molecular Diagnostics, 2016
Preimplantation genetic diagnosis (PGD) was introduced as an alternative to prenatal diagnosis: embryos cultured in vitro were analysed for a monogenic disease and only disease-free embryos were transferred to the mother, to avoid the termination of pregnancy with an affected foetus.

The Evolving Landscape of CHD Genetics: A Contemporary Guide to Genetic Testing and Management

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Congenital heart disease (CHD) is the most common birth defect, affecting an estimated 9.4/1000 infants globally. The genetics of CHD is complex, with most cases thought to have multifactorial aetiology, implicating both genetic and environmental factors.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
