These findings indicate that aortic stiffness might be accelerated in the TM group receiving gender-affirming hormone treatment, and suggest a potential deleterious effect of testosterone on arterial function. Preventive measures in TM individuals receiving testosterone treatment, who are at higher risk for cardiovascular events, are highly recommended.
