Erectile dysfunction: etiology and treatment in young and old patients.

This study shows that endocrine and vascular etiologies of erectile dysfunction are more common in the older age group, whereas depression and marital discord are more common in the younger age group. There is considerable overlap between various factors pointing to the multifactorial nature of erectile dysfunction. Review of the treatment option chosen reveals that the invasive modalities were least common as compared with the popular vacuum tumescence device (although cumbersome) and testosterone replacement.
