Sex is a basic instinct like hunger. Sexual activity, however, demands complete concentration and relaxation. It cannot be performed in haste and tension. People who are usually tense and over occupied are unable to follow these norms. Many Persons, therefore, suffer from sexual dysfunctions. The most common male sexual dysfunction is impotence.
Symptoms Impotence takes three forms. There is primary impotence when the man's erectile dysfunction is there from the very beginning of sexual activity and he simply cannot have an erection. Secondary impotence is the commonest and this implies that the man can normally attain an erection but fail on one or more occasions in between normal activity. The third form is associated with advancing age.
Sexual impotence may result from psychological illness such as depression which lowers both sexual drive and erectile function, tiredness, alcohol abuse, the therapeutic use of oestrogens, paralysis of parasympathetic nerves by drugs or permanent damage to them, and diabetes. Other causes of impotence include a devitalized condition of the system in general. The main problem of secondary impotence is the apprehension created by an earlier failure, which generates a good deal of anxiety for the next time.
