What are the main causes of impotence? What is the best treatment of impotence?
Apart from the partnership relationship dynamics you refer to probably the biggest cause of impotence is smoking. As one ages most men are prone to suffer from circulatory disease due to the build up of plaque deposits on the walls of arteries (bad diet, too little exercise). This effect is made worse by smoking because nicotine causes the arteries and veins to contract further restricting the flow of blood. The penis is one of the first organs to be affected by the decline in blood flow so impotence can be often viewed as an early warning sign for circulatory problems – heart attack or stroke. Therefore I view smoking as a prime cause of impotence.
