CONTEXT: Suboptimal endometrial thickening is associated with lower pregnancy rates and occurs in some infertile women treated with clomiphene. OBJECTIVE: To examine cellular and molecular differences in the endometrium of women with subopt…

C-X-C ligand 13 (CXCL13), a regulator of mucosal immunity, is secreted by human endometrial epithelium and may be involved in embryo implantation. However, cyclic expression of human endometrial CXCL13 in health and disease is not well stud…

Rapid estrogen effects are mediated by membrane receptors, and evidence suggests a role for both a membrane-associated form of estrogen receptor alpha (ESR1; ERα) and G-protein coupled receptor 30 (GPER; GPR30). Considering estrogen's impor…

Endometrium attains a secretory architecture in preparation for embryo implantation, but the identity of most endometrial secretory products remains unknown. Our objective was to characterize the endometrial secretome and compare protein ex…

ContextIt is generally assumed that delayed endometrial development observed in luteal phase deficiency (LPD) is the result of abnormally low progesterone (P) levels. This hypothesis has never been tested by direct experiment.ObjectiveOur o…

OBJECTIVE: To compare traditional histologic dating criteria of the endometrium with immunohistochemical criteria based on epithelial integrin expression during the menstrual cycle. DESIGN: Prospective clinical study. SETTING: An academic…

OBJECTIVE: To compare the expression of endometrial P receptors (PR) levels with markers of endometrial receptivity during the window of implantation. DESIGN: Prospective, controlled study to examine endometrial PR and three cycle-specific…
