After the age of 40 ,a significant number of males suffer from erectile dysfunction (E.D) .E.D also known as impotence occurs when there is a lack of blood flow to the penis .This means that a man can have trouble getting and keeping an erection long enough to have sex. It may happen only once in a while or more often. An estimated 30 million Americans suffer from E.D. This would give you a fair idea of what could be the worldwide figures.

But it is not only E.D. which could adversely affect a successful sexual intercourse. Unknown to most of us there are other serious diseases which could impair your sexual activity, besides of course S.T.D. (sexually transmitted diseases) .Peyronie’s disease, is one disorder affecting the penis that can prevent sexual intercourse. Peyronie's disease is characterized by the formation of hardened tissue (fibrosis) in the penis that causes pain, curvature, and distortion, usually during erection.

The penis (male organ for reproduction and urination) is composed of two columns of erectile tissue (corpora cavernosa); the corpus spongiosum, which contains the urethra (tube that carries urine and semen from the body); and the tunica albuginea (sheath that surrounds the erectile tissue). In Peyronie's disease, dense, fibrous scar tissue (plaque) forms in the tunica albuginea.

There are three main symptoms of Peyronie's disease - pain, lumps in the penis and bending of the penis, but these are not present in all men and vary in severity. Some men initially experience pain in their penis when they have an erection. Often this painful stage will disappear without any treatment. At this stage the man may be able to feel firm lumps (known as plaques) in the shaft of the penis.

As these plaques develop he will notice bending or angulation of the penis when erect. In severe cases this distortion of the penis can make sexual intercourse impossible or extremely uncomfortable for both partners. Obviously, problems with sexual intercourse, especially with a longstanding partner and in a loving relationship are stressful. The psychological impact can be devastating, no matter how understanding the partner is. Sometimes worrying about the problem and the difficulties experienced during sexual intercourse can make the man impotent.

The cause for the disease could be the result of injury. Peyronie's disease is more common after injury to the penis, such as penile fracture or forceful bending of the erect penis .Circulatory disorders (high blood pressure and hardening of the arteries) and diabetes sometimes also contribute to the development of Peyronies. Although not common genetic factors may also be a cause for this affliction. Depending on the severity of the problem physicians decide on the treatment. At times even surgery might be required.
