Types Of Erectile Dysfunction

Types Of Erectile Dysfunction

What is erectile dysfunction (ED)?

Erectile dysfunction is defined as the persistent inability to achieve or maintain penile erection sufficient for satisfactory sexual performance. The Massachusetts Male Aging Study surveyed 1,709 men aged 40–70 years between 1987 and 1989 and found there was a total prevalence of erectile dysfunction of 52 percent. It was estimated that, in 1995, over 152 million men worldwide experienced ED. For 2025, the prevalence of ED is predicted to be approximately 322 million worldwide.In the past, erectile dysfunction was commonly believed to be caused by psychological problems. It is now known that, for most men, erectile dysfunction is caused by physical problems, usually related to the blood supply of the penis. Many advances have occurred in both diagnosis and treatment of erectile dysfunction.

What are the different types (and causes) of ED?

The following are some of the different types and possible causes of erectile dysfunction:

  • Organic Erectile Dysfunction

Organic ED involves abnormalities the penile arteries, veins, or both and is the most common cause of ED, especially in older men. When the problem is arterial, it is usually caused by arteriosclerosis, or hardening of the arteries, although trauma to the arteries may be the cause. The controllable risk factors for arteriosclerosis--being overweight, lack of exercise, high cholesterol, high blood pressure, and cigarette smoking--can cause erectile failure often before progressing to affect the heart.

Premature Ejaculation (PE)

  • Premature ejaculation is a male sexual dysfunction characterized by:
  • Ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration.
  • Inability to delay ejaculation on all or nearly all vaginal penetrations; and, negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy.
  • Premature ejaculation is divided into lifelong and acquired categories:
  • Lifelong premature ejaculation. With lifelong premature ejaculation, the patient has experienced premature ejaculation since first beginning coitus.
  • Acquired premature ejaculation. With acquired premature ejaculation, the patient previously had successful coital relationships and only now has developed premature ejaculation

How is ED diagnosed?

Diagnostic procedures for ED may include the following:

  • Patient medical or sexual history. This may reveal conditions or diseases that lead to impotence and help distinguish among problems with erection, ejaculation, orgasm, or sexual desire.
  • Physical examination. To look for evidence of systemic problems, such as the following:
  • A problem in the nervous system may be involved if the penis does not respond as expected to certain touching.
  • Secondary sex characteristics, such as hair pattern, can point to hormonal problems, which involve the endocrine system.
  • Circulatory problems could be indicated by an aneurysm.
  • Unusual characteristics of the penis itself could suggest the basis of the impotence.

What causes an erection?

An erection is the result of increased blood flow into your penis. Blood flow is usually stimulated by either sexual thoughts or direct contact with your penis.When a man becomes sexually excited, muscles in their penis relax. This relaxation allows for increased blood flow through the penile arteries. This blood fills two chambers inside the penis called the corpora cavernosa. As the chambers fill with blood, the penis grows rigid. Erection ends when the muscles contract and the accumulated blood can flow out through the penile veins.ED can occur because of problems at any stage of the erection process. For example, the penile arteries may be too damaged to open properly and allow blood in.
