Immunological Role of the Maternal Uterine Microbiome in Pregnancy: Pregnancies Pathologies and Alterated Microbiota

Frontiers in Immunology, 2020
Understanding what happens at the time of embryo implantation has been the subject of significant research. Investigators from many differing fields including maternal fetal medicine, microbiology, genetics, reproductive endocrinology and immunology have

Integrin β1 coordinates survival and morphogenesis of the embryonic lineage upon implantation and pluripotency transition

Cell Reports, 2021
Summary: At implantation, the embryo establishes contacts with the maternal endometrium. This stage is associated with a high incidence of preclinical pregnancy losses. While the maternal factors underlying uterine receptivity have been investigated, the

Exosomes and soluble secretome from hormone-treated endometrial epithelial cells direct embryo implantation.

Molecular human reproduction, 2020
A successful pregnancy requires a synchronous dialogue between endometrium and embryo within the endometrial milieu. The aim of this study was to assess the role in implantation of mediators in the endometrial milieu.

MicroRNAs in Small Extracellular Vesicles Indicate Successful Embryo Implantation during Early Pregnancy

Cells, 2020
Synchronous communication between the developing embryo and the receptive endometrium is crucial for embryo implantation. Thus, uterine receptivity evaluation is vital in managing recurrent implantation failure (RIF).

The mechanism of hydrosalpinx in embryo implantation [PDF]

Human Reproduction, 2001
Hydrosalpinx adversely affects embryo implantation and contributes to poor implantation rates post embryo transfer. Embryo transport depends on concomitant intrauterine fluid motion induced by uterine wall motility, the result of spontaneous myometrial contractions towards the fundus.The uterine dynamics of five patients with hydrosalpinx were recorded

Reactive oxygen species in the mammalian pre-implantation embryo.

Reproduction, 2022
Reactive Oxygen Species (ROS) occur naturally in pre-implantation embryos as a by-product of ATP generation through oxidative phosphorylation and enzymes such as NADPH oxidase and xanthine oxidase.

Using Unlabeled Information of Embryo Siblings from the Same Cohort Cycle to Enhance In Vitro Fertilization Implantation Prediction

Advanced Science, 2023
High‐content time‐lapse embryo imaging assessed by machine learning is revolutionizing the field of in vitro fertilization (IVF). However, the vast majority of IVF embryos are not transferred to the uterus, and these masses of embryos with unknown ...

Assisted reproductive technology in the USA: is more regulation needed? [PDF]

, 2014
The regulation of assisted reproductive technologies is a contested area. Some jurisdictions, such as the UK and a number of Australian states, have comprehensive regulation of most aspects of assisted reproductive technologies; others, such as the USA ...

Uterine Selection of Human Embryos at Implantation [PDF]

Scientific Reports, 2014
Human embryos frequently harbor large-scale complex chromosomal errors that impede normal development. Affected embryos may fail to implant although many first breach the endometrial epithelium and embed in the decidualizing stroma before being rejected via mechanisms that are poorly understood.

Ultrastructure of cytoplasmic fragments in human cleavage stage embryos [PDF]

, 2016
Purpose: The goal of this study was to evaluate the ultrastructure of cytoplasmic fragments along with the effect of cytoplasmic fragment and perivitelline space coarse granulation removal (cosmetic microsurgery) from embryos before embryo transfer on ...
