Male Erectile Disorder
It is believed that erectile dysfunction is primarily a function of anxiety about sexual performance. It is also a common consequence of aging. Prolonged or permanent erectile disorder before the age of 60 is relatively rare. One study found that more than half of married men over 70 had some erectile difficulties.
Increased erectile dysfunction with age, and erectile disorder in general, are increasingly viewed as medical rather than pyschological problems. The most frequent cause of erectile disorder in older men is vascular disease, resulting in decreased blood flow to the penis or in diminished ability of the penis to hold blood to maintain an erection. Thus, hardening of the arteries, high blood pressure, and other diseases causing vascular problems are often causes of erectile disorder. Diseases that affect the nervous system, such as multiple sclerosis, can also cause erectile problems.
A variety of treatment have been employed in recent years to correct erectile dysfunction. These include drugs such as yohimbine, injections of smooth muscle relaxing drugs into the penile erection chambers and even a vacuum pump. In extreme cases, penile implants may be used. These devices can be inflated to provide erection on demand. They are made of silicone rubber or polyurethane rubber.
There has been immense public interest in the new drug Viagra which works by facilitating nitric oxide, the primary neurotransmitter involved in penile erection. Viagra is taken orally, at least one hour before sexual activity. Unlike some other biological treatments for erectile dysfunction, Viagra promotes erection only if sexual desire is present. In a study, over 70% of men receiving Viagra reported that their erections had improved. Viagra may be the most commercially successful drug ever marketed.
