Androgens are essential for the development of the penis and it is well known that testosterone play a critical role in the physiology of erectile function. From animal studies, testosterone insufficiency disrupts cellular-signaling pathways and induces pathologic alterations in penile tissues leading to erectile dysfunction. In human, the testosterone threshold for maintaining erection is low which explains the reason why some contracted men still have an erection due to the androgens produced by the adrenal gland. Testosterone alone can improve erectile function in hypogonadic patients. Associated with PDE5-I, testosterone supplementation is a treatment for the hypogonadic patients non responders to therapy. The article reviews the different aspects of the testosterone role in the pathophysiology of erection.
