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

Defective endometrial receptivity

Fertility and Sterility, 2012
The endometrium is one of the most fascinating tissues in the human body. Its sole purpose is to enable implantation of an embryo during a relatively short window of opportunity in the menstrual cycle. It is becoming clear that overcoming the current bottleneck in improvements to assisted reproductive techniques will require a closer look at the ...

Biomarkers of Endometrial Receptivity—A Review

Placenta, 2003
Implantation is a phenomenon that involves an interaction between the embryo and maternal endometrium. There is, in the menstrual cycle, a short and precise period of time in which the maternal-embryonic interaction is optimal and culminates with adhesion and invasion of the blastocyst into the progesterone-induced secretory endometrium. This period is

Endometrial receptivity and pregnancy outcome

The Journal of Maternal-Fetal & Neonatal Medicine, 2020
Human implantation is a highly complex and multifactorial process. Successful implantation requires the presence of a healthy embryo, a receptive endometrium, and a synchronized molecular dialogue between the two, as well as immune tolerance/protection from the host.

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.

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.

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

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'.

Endometrial receptivity in women with endometriosis

Best Practice & Research Clinical Obstetrics & Gynaecology
As endometriosis is recognized as a contributing factor to infertility, prompting couples to embark on Assisted Reproductive Technology (ART) treatments, it becomes crucial to comprehend the extent and way this condition can affect success rates. Natural conception data reveal lower success rates for women with endometriosis, yet the same cannot be ...
