There is various treatment for impotence depending upon the underlying cause. These may include measures to combat stress, counseling and sexual therapy to help resolve relationship problems, changes in lifestyle, weight control, alternation in prescribed medication which causes impotence, pelvic floor exercises, use of an oral medication, a vacuum device or injection or insertion of medicine into the penis.

For those men whose impotence has resulted from injury to nerves and blood vessels supplying the penis, two forms of the penile implant can be inserted by means of surgical operation.

• Diseases such as diabetes mellitus, an endocrine gland disorder, kidney disease, multiple sclerosis, etc.
