Computational tools in rehabilitation of erectile dysfunction.

Erectile dysfunction (ED) is defined as the inability to achieve and maintain an erection adequate for satisfactory intercourse. It is a common problem among approximately 50% of men between the ages of 40 and 70. Erectile dysfunction is not only stressful to both the affected individual and his partner, but it can also negatively affect self-esteem. Biomechanical models have recently been developed to study both the structural and hemodynamic factors involved in normal and pathological erectile conditions. These computational models, which are reviewed in the present paper, allow for better understanding of the mechanisms acting in ED and provide a suitable basis for development of state-of-the-art interdisciplinary treatment approaches aimed to improve the quality of life for these men.
