The endometrium becomes receptive to the embryo only in the mid-luteal phase, but not in
the other stages of the menstrual cycle. Endometrial factors play an important role in …

BACKGROUND Gene expression profiling of normal receptive endometrium has been
characterized, but intrinsic defects in endometrial gene expression associated with …

The aim of this prospective cohort study was to identify altered biologic processes in the
endometrium that may be potential markers of receptive endometrium in patients with …

High endometrial receptivity in the window of implantation (WOI) is essential for successful
implantation. However, a diagnostic tool with high specificity for impaired endometrial …

Context: Identifying novel molecular markers for assessing endometrial receptivity is
necessary for understanding human implantation and may help in improving the clinical …

STUDY QUESTION Is endometrial recurrent implantation failure (RIF) only a matter of an
asynchronous (displaced) window of implantation (WOI), or could it also be a pathological …

Recurrent implantation failure (RIF) is diagnosed when good-quality embryos repeatedly fail
to implant after transfer in several in vitro fertilization (IVF) treatment cycles. Different …

Background Endometrial function is essential for embryo implantation. The aim of this study
was to analyze gene expression profiles from individual endometrial samples obtained from …

Estradiol and progesterone are crucial for the acquisition of receptivity and the change in
transcriptional activity of target genes in the implantation window. The aim of this study was …

Background Window of implantation (WOI) displacement is one of the endometrial origins of
embryo implantation failure, especially repeated implantation failure (RIF). An accurate …
