Impotence is defined as the inability to achieve and maintain an erection adequate for satisfactory intercourse. It is a common problem for approximately 50% of men between the ages of 40 and 70. Impotence not only creates mental stresses in both the patient and his partner, but also can negatively affect self-esteem. Knowledge of the mechanical behavior of the penis during erection, including the stress distribution developing within its structural components, is a key for understanding not only the normal sexual function but will also allow better comprehension of some of common erectile dysfunction (ED) conditions [1-3]. Current technology is limiting direct measurements of the mechanical stress distribution within the living human penis during erection. Hence, analysis of computational simulations, obtained through use of a realistic three-dimensional (3D) biomechanical penis model, is the only feasible alternative to carry out such an investigation, and open new approaches for treatment of ED.
