Background: Reproductive endocrine disorder can impair endometrial receptivity, preventing embryo implantation and increasing miscarriage risk. Impaired endometrial receptivity contributes significantly to female infertility. Inflammatory signaling pathways including the IL-6/STAT3 pathway help embryos implant. Therefore, it is crucial to explore the relationship between the IL-6/STAT3 signaling pathway and endometrial receptivity.
Objective: To investigate the mechanism by which Bushen Zhuyun decoction (BSZY) enhances endometrial receptivity in rats through the IL-6/STAT3 signaling pathway.
Methods: Mifepristone-induced poor endometrial receptivity models of female SD rats were established, followed by histopathological observation. ELISA was used to measure serum sex hormones and VEGF. Western blotting or IHC was used to measure steroid receptors, IGFBP1, and IL-6/STAT3 pathway activation in the uterus during each estrus cycle and early gestation of normal rats. The Treg/Th17 balance was assessed using flow cytometry.
Results: Significant differences were found in the protein expressions of steroid receptors, IL6, STAT3, and p-STAT3 during each estrus cycle and early gestation of normal rats. The protein expressions of STAT3 and PR were strongly correlated with each other. BSZY notably improved uterine morphology increased the expression of implantation markers and raised the serum concentrations of sex hormones and VEGF. BSZY enhanced the expressions of IL-6 and its receptors and restored the expressions of STAT3 and p-STAT3 in the uterus of pregnant rats. In addition, BSZY effectively restored the Treg/Th17 balance in the peripheral blood of pregnant rats.
Conclusion: BSZY enhances endometrial receptivity and promotes decidualization in SD rats via the IL-6/STAT3 signaling pathway.

The downregulation of anti-adhesive regulatory proteins and upregulation of adhesive genes are critical for the receptive endometrium. This study was designed to determine whether switching between the anti-adhesive podocalyxin (PDX) and adhesive HOXA10 receptivity modulator occurs in the endometrium of women with recurrent implantation failure (RIF). Twenty-four patients with RIF who could not conceive for three or more cycles despite good-quality embryo transfer constituted the study group.

Reduced lymphoid enhancer-binding factor 1 (LEF1) expression in patients with adenomyosis during the mid-secretory phase leads to impaired endometrial receptivity, affecting embryo implantation. This study investigated the molecular mechanisms underlying reduced endometrial receptivity in 25 adenomyosis patients and 25 controls. Functional experiments were conducted using human endometrial stromal cells (HESCs) and TERT-immortalized HESCs(T-HESCs), with final validation performed using a mouse model.

Background: Embryo implantation involves two key elements: a good quality embryo and receptive endometrium. Endometrial receptivity abnormalities are known as one of the possible causes of recurrent implantation failure (RIF), especially when the embryo is euploid. This study was aimed to evaluate the impact of age and other clinical factors on endometrial receptivity in women with RIF.

Background: Recurrent pregnancy loss (RPL) poses significant challenges in clinical management due to an unclear etiology in over half the cases. Traditional screening methods, including ultrasonographic evaluation of endometrial receptivity (ER), have been debated for their efficacy in identifying high-risk individuals. Despite the potential of artificial intelligence, notably deep learning (DL), to enhance medical imaging analysis, its application in ER assessment for RPL risk stratification remains underexplored.

Uterine infections reduce ruminant reproductive efficiency. Reproductive dysfunction caused by infusion of Gram-negative bacteria is characterized by the failure of embryo implantation and reduced conception rates. Lipopolysaccharide (LPS), a major component of the outer membrane of Gram-negative bacteria, is highly abortogenic.
