More in details, in equine and bovine in vitro maturation IVM systems, follicular fluidderived EVs or small EVs administered at fixed concentrations over defined culture periods improved oocyte nuclear maturation and subsequent embryo developmental competence, particularly under conditions of metabolic stress ( in vitro models, such as primary porcine theca cells, a broader doseresponse evaluation revealed that EV treatment (30120 g/mL for 24 h) reduced reactive oxygen species accumulation, limited apoptosis, and enhanced steroidogenic activity, underscoring the importance of aligning EV dose and duration with the specific stress paradigm and cellular target ( Conversely, murine oocyte co-culture experiments using EVs derived from follicular fluid of older women demonstrated that short-term exposure (14 h) to age-associated EV populations can exacerbate oxidative stress, mitochondrial dysfunction, and spindle abnormalities, ultimately impairing oocyte maturation ( in vitro model of aged ovarian follicles to investigate the contribution of extracellular vesicles
