Popis: Arteriovenous fistulae (AVF) fail to mature in female patients compared with male patients, leading to inferior outcomes and decreased utilization. As our mouse AVF model recapitulates sex differences in human AVF maturation, we hypothesized that sex hormones mediate these differences during AVF maturation. C57Bl/6 mice (9-11 week) underwent aortocaval AVF surgery and gonadectomy. AVF hemodynamics were measured via ultrasound (days 0-21). Blood was collected for FACS, and tissue for immunofluorescence and ELISA (days 3,7); wall thickness was assessed using histology (day 21). Inferior vena cava (IVC) shear stress was higher in male mice (p=0.0028) after gonadectomy, and they had increased wall thickness (22.0 ± 1.8 um vs. 12.7 ± 1.2; p
