BACKGROUND: Embryo implantation failure and early pregnancy loss remain significant challenges in assisted reproductive technology (ART). Lipid peroxidation is known to be involved in reproductive physiology. However, its role during the im…

Defective endometrial receptivity represents an important factor in recurrent implantation failure (RIF), though its precise regulatory mechanisms remain unclear. While nicotinamide N-methyltransferase (NNMT) is abundantly expressed in huma…

BACKGROUND: The aim of the retrospective cohort study was to investigate the prognostic effect of subchorionic hematomas (SCH) in the first trimester on pregnancy outcomes after euploid embryo transfer. METHODS: We retrospectively analyzed…

BACKGROUND: The association of dyslipidemia with embryo development and pregnancy outcomes is largely unknown, especially in unexplained recurrent implantation failure (uRIF) patients. Here, this study aimed to explore the impact of abnorma…

IMPORTANCE: Implantation failure remains a critical barrier to in vitro fertilization. Prednisone, as an immune-regulatory agent, is widely used to improve the probability of implantation and pregnancy, although the evidence for efficacy is…

BACKGROUND: Recurrent implantation failure (RIF) is a disease associated with endometrial receptivity dysfunction. Retinoic acid receptor alpha (RARα) is an important protein in many biological processes, such as differentiation and develop…

Increasing evidence has revealed a close relationship between non-coding RNAs and recurrent implantation failure (RIF). However, the role of circular RNAs (circRNAs) in RIF pathogenesis remains largely unknown. Microarray analyses were used…

PURPOSE: To evaluate whether miR-148a-3p overexpression is associated with disrupted decidualization of recurrent implantation failure (RIF). METHODS: Endometrial miRNA and mRNA expression profiles during the implantation window derived fr…
