Traumatic brain injuries (TBI) occur in 1.7 million people each year in the USA. Little is known about how the cerebrovasculature is altered after TBI. We previously reported that TBI elicits acute decrements in cerebral vessels near the injury site in rats followed by revascularization over the subsequent 2 weeks. Sexual dimorphism of the brain is well documented and different hormonal levels in males and females differentially modify the recovery process after injury. However, the effects of biological sex on the temporal evolution of revascularization following TBI are understudied. Using a model of controlled cortical impact in male and female mice, we set out to determine if the injury and the repair process are affected by sex.
