The function of metformin in endometrial receptivity (ER) of patients with polycyclic ovary syndrome (PCOS): a systematic review and meta-analysis

Reproductive Biology and Endocrinology, 2021
Background This meta-analysis summarizes evidence from studies using metformin (Met) to improve endometrial receptivity (ER) in women with PCOS. Methods Following the PRISMA protocol, we conducted a comprehensive search of academic literature from ...

Histone Deacetylase 3‐Progesterone Receptor Cooperation Regulates Progesterone Responsiveness in the Uterus

MedComm, Volume 7, Issue 11, November 2026.
HDAC3 and PGR exhibit coordinated expression and chromatin occupancy in the receptive endometrium. Loss of HDAC3‐PGR cooperation in endometriosis disrupts progesterone‐responsive gene regulation and impairs uterine receptivity. ABSTRACT Endometriosis affects a substantial proportion of women of reproductive age, with 30%–50% affected by infertility.

Relationship between advanced maternal age and decline of endometrial receptivity: a systematic review and meta-analysis

Aging, 2023
Female fertility decreases with age. A decline in oocyte quality plays a key role in reproductive problems in older women. Whether advanced maternal age (AMA) is associated with a decline in endometrial receptivity (ER) remains controversial. A systematic review and meta-analysis were conducted to evaluate the relationship between AMA and ER.

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

Advanced Science, Volume 13, Issue 55, 5 October 2026.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

Endometrial aging and uterine receptivity: endometrial receptivity analysis (ERA) outcomes in female patients of diverse age groups

Journal of Assisted Reproduction and Genetics
Abstract Purpose To assess whether the endometrial receptivity analysis (ERA) captures receptivity changes attributed to endometrial aging and whether it may be useful for older patients undergoing fertility treatment. Methods

15 years of transcriptomic analysis on endometrial receptivity: what have we learnt? [PDF]

Fertility Research and Practice, 2019
Over the course of the last four decades, IVF has allowed an increasing number of infertile couples the chance to conceive. Considering the extensive research and advances in ART, too many IVF attempts still do not result in a successful pregnancy [1, 2]. Embryo implantation is a crucial event in the establishment of a pregnancy.

A Review of the Molecular Basis for Reduced Endometrial Receptivity in Uterine Fibroids and Polyps

, 2017
The presence of fibroids and endometrial polyps is associated with reduced endometrial receptivity and subsequent fertility outcomes. The following review explores the molecular mechanisms behind reduced endometrial receptivity, with a focus upon homebox

Current knowledge on the role of extracellular vesicles in endometrial receptivity

, 2023
Endometrial receptivity has been widely understood as the capacity of the endometrium to receive implantable embryos. The establishment of endometrial receptivity involves multiple biological processes including decidualization, tissue remodeling ...

Clinical view of the ineffectiveness of IVF problem with endometrial receptivity

Репродуктивная эндокринология, 2017
Objective: To review the literature for studying the mechanisms of influence of superovulation on the receptivity of the endometrium in vitro fertilization (IVF), which is largely due not only to the quality of the embryo, but with the condition of the ...
