BACKGROUND: In the field of in vitro fertilization (IVF), the search for reliable success predictors is ongoing, with novel biomarkers gaining increasing attention. Epigenetic clocks, mathematical models based on DNA methylation (DNAm) patt…

OBJECTIVE: To evaluate whether telomere length (TL), mitochondrial-DNA (mt-DNA) or epigenetic age estimators based on DNA methylation (DNAm) pattern could be considered reliable predictors of in-vitro-fertilization (IVF) success in terms of…

Women undergoing in vitro fertilization (IVF) are emotionally challenged. Anxiety, depression, and sleep disturbances are common complaints. The impact of these symptoms on IVF outcome is however debated. In this study, we aimed at investig…

OBJECTIVE: To study whether increased body mass index is associated with altered expression of extracellular vesicle microRNAs (EV-linked miRNAs) in human follicular fluid. DESIGN: Cross-sectional study. SETTING: Tertiary-care university-…

Bisphenol A (BPA) is a widely used chemical that has been detected in follicular fluid and associated with adverse reproductive effects. Granulosa cells have an important role in follicular growth and oocyte maturation, however, little is k…

BACKGROUND: Phenols and phthalates are potential endocrine disrupting chemicals (EDCs) that are associated with adverse health outcomes. These EDCs dysregulate a number of biomolecules and pathways, including microRNAs. MicroRNAs can be car…

Encapsulated microRNAs (i.e., miRNAs within the extracellular vesicles, i.e., EV-miRNAs) have been detected in follicular fluid in both animal and human studies and different profiles have been associated with IVF cycle characteristics. How…

BACKGROUND: The exposome encompasses all life-course environmental exposures from the prenatal period onward that influence health. MicroRNAs (miRNAs) are interesting entities within this concept as markers and causation of disease. MicroRN…
