Understanding implantation window, a crucial phenomenon

open access: yesJournal of Human Reproductive Sciences, 2012
Embryo implantation is a well-defined and precise process, in which various factors come into play one after the other. There is only a specific period of time during which implantation is possible i.e. “implantation window”. Selectins were proposed to have an important role in this phase to ensure suitable rolling of the blastocyst.

Implantation Window and Angiogenesis

open access: yesJournal of Cellular Biochemistry, 2017
ABSTRACTIn recent decades, infertility is one of the health problems worldwide. One of the most crucial events in reproductive period is implantation window (IW). In the time after IW period, the embryo cannot connect to the endometrium; therefore the most critical issue for successful implantation is timely entrance of embryo to the uterine cavity ...

[The implantation window]. [PDF]

open access: yesJournal de gynecologie, obstetrique et biologie de la reproduction, 2002
Embryo implantation is a complex event involving apposition followed by adhesion of the blastocyst to the maternal endometrium, and finally invasion of this endometrium. Though implantation could occur in any human tissue, the endometrium is the only tissue where embryo implantation cannot occur except during a restricted period called the implantation

Restraint stress inhibits mouse implantation: temporal window and the involvement of HB-EGF, estrogen and progesterone. [PDF]

open access: yesPLoS ONE, 2013
It is known that psychological stress affects reproduction in women, but it is unknown whether the effect is by impairing implantation. Although studies suggest that long periods of auditory or restraint stress may inhibit implantation in rats and mice ...

Interaction between lysophosphatidic acid, prostaglandins and the endocannabinoid system during the window of implantation in the rat uterus.

open access: yesPLoS ONE, 2012
Bioactive lipid molecules as lysophosphatidic acid (LPA), prostaglandins (PG) and endocannabinoids are important mediators of embryo implantation. Based on previous published data we became interested in studying the interaction between these three ...

Chronic cranial window implantation for high-resolution intravital imaging of the endothelial glycocalyx in mouse cortex

open access: yesSTAR Protocols, 2023
Summary: The endothelial glycocalyx is an integral component of the brain vascular barrier. Visualizing its structure in vivo is essential to understand its physiological and pathophysiological mechanisms. Here, we present a surgical protocol for chronic

High Stromal Senescence During the Window of Implantation Is Linked to Plasma Cell Presence and Cluster Formation in the Endometrium

open access: yesImmuno
Successful implantation requires a finely regulated endometrial microenvironment during the window of implantation. Chronic endometritis, defined by plasma cell infiltration, and stromal senescence, indicated by p16 expression, represent separate but ...

The clinical efficiency of transcriptome-based endometrial receptivity assessment (Tb-ERA) in Chinese patients with recurrent implantation failure (RIF): A study protocol for a prospective randomized controlled trial

open access: yesContemporary Clinical Trials Communications, 2022
Background: Today, approximately 10% of participants in assisted reproductive technology (ART) are defined as having recurrent implantation failure (RIF). Recent studies show that endometrial receptivity array can improve pregnancy and implantation rates
