Introduction: Hypospadias is often associated with reduced testosterone synthesis or action. High rates of complications are reported with surgical repair of hypospadias, including wound dehiscence. Boys with hypospadias have previously been demonstrated to have increased reactive oxygen species (ROS) compared to healthy controls and there is a known link between male hypogonadism and oxidative stress. It is not clear what effect ROS has on wound healing in bo...

Background: Hypospadias in boys may be associated with a lack of androgen exposure during the masculinisation programming window. As testosterone has effects on the vasculature, we assessed whether boys with hypospadias show any evidence of vascular dysfunction.Methods: Excess foreskin tissue was obtained from boys undergoing hypospadias repair (cases) or circumcision (controls) and small arteries dissected from this tissue. Vascular contractility was as...

Background: Hypogonadism has been associated with cardiovascular disease. However, little is known about the cardiovascular impact of hypogonadism during development. Using hypospadias as a surrogate of hypogonadism, we investigated whether hypospadias is associated with vascular dysfunction during childhood and whether it is a risk factor for adult cardiovascular disease.Methods: Our human study spanned molecular mechan...
