The role of extracellular vesicles in endometrial receptivity and their potential in reproductive therapeutics and diagnosis.

Reproductive Biology, 2022
Extracellular vesicles (EVs) are small, nanometre sized, membrane-enclosed structures released by cells and are thought to be crucial in cellular communication.

Clinical Management of Endometrial Receptivity

Seminars in Reproductive Medicine, 2014
The endometrial window of implantation (WOI), the cycle days during which normal embryo implantation can occur, has generally been assumed to begin on cycle day 19 or 20 of an idealized 28 days cycle and last for 4 to 5 days. Noyes et al took the first steps in defining the WOI by establishing a set of morphological criteria to evaluate endometrial ...

Effects of mifepristone on endometrial receptivity

Steroids, 2003
At the development of receptivity the endometrium undergoes specific changes. Several factors have been suggested as markers of endometrial receptivity. A common feature for most of these factors is that they are directly, or indirectly, regulated by progesterone.

From Endometrial Receptivity to Infertility

Seminars in Reproductive Medicine, 1999
Implantation of the blastocyst in endometrium requires establishment of a coordinated molecular dialogue between the embryo and the endometrium. Factors instrumental in the preparation of a receptive endometrium are derived from the hypothalamic-pituitary-gonadal axis. These factors modulate the expression of genes that drive the endometrium throughout

Evaluation of endometrial receptivity and implantation failure

Current Opinion in Obstetrics and Gynecology, 2022
Purpose of review To succinctly review the basic mechanisms of implantation and luteal phase endometrial differentiation, the etiologies of impaired endometrial function and receptivity, and the current methods that exist to evaluate and treat impaired ...

Understanding and improving endometrial receptivity

Current Opinion in Obstetrics & Gynecology, 2015
For a successful pregnancy, the synchronic coordination between the embryonic development and the endometrial status is crucial. The endometrium is a hormonally regulated organ that is nonadhesive to embryos throughout most of the menstrual cycle in humans.

Endometrial Receptivity by Endometrial Receptivity Analysis (ERA) for Infertility

2019
The endometrial factor plays a key role in implantation, being one of the responsible for recurrent implantation failure (RIF). Along years, many molecules implied in the acquisition of endometrial receptivity have been proposed as markers of this status, but as this phenotype is the consequence of several biological changes, it was needed to change to

Endometrial receptivity and the luteal phase

Current Opinion in Obstetrics and Gynecology, 1992
Endometrial receptivity to the implanting blastocyst determines whether pregnancy occurs. Whether fertilization is initiated in vivo or in vitro, the receptivity of the luteal-phase endometrium results from the input of interacting hormonal, growth, and immunologic factors.

Endometrial Pinopodes and Uterine Receptivity

Annals of the New York Academy of Sciences, 2003
Abstract: The human endometrium is an extremely sensitive target for steroid hormones. During the menstrual cycle, this tissue undergoes dynamic changes which are reflected on the surface morphology of the epithelium, and which can be followed by scanning electron microscopy. The morphological changes peak at the midsecretory phase, with the formation

Endometrial receptivity and the window of implantation

Best Practice & Research Clinical Obstetrics & Gynaecology, 2000
Implantation is a highly co-ordinated event that involves both embryonic and endometrial participation. The endometrium expresses a sophisticated repertoire of proteins during the menstrual cycle many of which help to define a period of receptivity collectively known as the 'window of implantation'.
