BACKGROUND Fertility depends on a receptive state of the endometrium, influenced by
hormonal and anatomical adaptations, as well as the immune system. Local and systemic …

Embryo implantation involves the intimate interaction between an implantation-competent
blastocyst and a receptive uterus, which occurs in a limited time period known as the …

Implantation is a highly organized process that involves an interaction between a receptive
uterus and a competent blastocyst. In humans, natural fecundity suggests that the chance of …

Intensive research work has been performed to better understand the regulation of the
endometrium and its clinical implications to improve implantation. Although many proteins …

In humans, embryonic implantation and reproduction depends on the interaction of the
embryo with the receptive endometrium. To gain a global molecular understanding of …

Background L-arginine is considered to be one of the most versatile amino acids due to the
fact that it serves as a precursor for many important molecules in cellular physiology. When …

This article highlights the need for methods to objectively diagnose endometrial receptivity
as a factor contributing to infertility in female patients. The correct identification of the …

At implantation, trophectoderm attaches to the apical uterine luminal epithelial cell surface.
Molecular anatomy studies in humans and mice, and data from experimental models have …

Pregnancy is established during the periconceptional period as a continuum beginning with
blastocyst attachment to the endometrial epithelial surface followed by embryo invasion and …

The endometrium undergoes substantial remodeling in each menstrual cycle to become
receptive to an implanting embryo. Abnormal endometrial receptivity is one of the major …
