Estrogen and progesterone and their signaling mechanisms are tightly regulated to maintain
a normal menstrual cycle and to support a successful pregnancy. The imbalance of estrogen …

The aim of the present systematic review and meta-analysis was to assess the effect of the
different therapeutic options for repeated embryo implantation failure (RIF) on a subsequent …

Mechanisms of implantation such as determination of the attachment pole, fetal-maternal
communication, and underlying causes of implantation failure are largely unexplored. Here …

Human embryo implantation is an intricate spatiotemporal process that involves the intimate
association between the embryo and the endometrium of the mother. During implantation …

Introduction: Despite great advances in assisted reproductive technology (ART), recurrent
implantation failure (RIF) cannot be effectively avoided. Notably, cellular characteristics and …

Successful outcomes of in vitro fertilization (IVF) rely on both the formation of a
chromosomally normal embryo and its implantation in a receptive endometrium. Pre …

Decidualization is characterized by a series of genetic, metabolic, morphological,
biochemical, vascular and immune changes occurring in the endometrial stroma in …

Background Recurrent implantation failure (RIF) is a major limitation of assisted reproductive
technology, which is associated with impaired endometrial receptivity. Although N 6 …

Recurrent implantation failure (RIF) is an imprecisely defined disorder lacking a robust
scientific basis. The incomplete understanding of RIF provides significant diagnostic and …

Background Successful implantation is a complex process that is influenced by embryo
quality, endometrial receptivity, immune factors, and the specific type of in vitro fertilization …
