Erectile Dysfunction

Erectile Dysfunction, or impotence, is a sexual disorder leading to the inability to achieve and maintain erection. The dysfunction is common for aged men, men with hormonal misbalance and can appear after serious traumas or a medical treatment.
Erection Mechanism
A penis is erected when the blood vessels inside it are filled with blood. Sex hormones worked out during a sexual arousal tell the brain to start the stimulation of nerves in the head of the penis. The greater is the stimulation, the firmer is the erection. When the stimulation is weak due to some reasons, men suffer from impotence and show a poor sexual performance in bed.
There exist 2 main types of erectile dysfunction:
1. Physical
2. Psychological
Physical erectile dysfunction is caused by physical reasons. They can include various diseases, a medical treatment, nerves injuries and other factors. Psychological erectile dysfunction occurs when there are no any evident reasons for poor erection and all the systems and organs in the body function properly. Such type of impotence can be a result of stress, depression or occasional failures in bed. Sometimes men cannot achieve or maintain erection due to some objective factors: lack of sleep, food or rest, stress or little time after the previous erection. Such single failure in bed can lead to a strong complex resulting in constant problems and impotence.
