Erectile Dysfunction

Diabetes affects the erectile function of 50% to 60% of men at one time or another as the disease progresses.

Sexual problems are often a taboo subject and many men have trouble talking about them. However, talking to a healthcare professional about it can help you learn more about the treatment options and ways to stop the situation from worsening.

How diabetes affects sexual function

Diabetes can have many adverse effects on sexual function, including an impact on:

  • the hormonal system, which controls the production of testosterone, the hormone of desire, whose rate may fall
  • the nervous system, which can impair erections if the person suffers from neuropathy, a complication of diabetes
  • the cardiovascular system, which can obstruct the penile arteries
  • the immune system, causing a man with diabetes to be at higher risk of infection, such as a fungal infection of the foreskin

Erectile dysfunction

Diabetes is one of the main causes of erectile dysfunction. Consequently, erectile dysfunction is one of the sexual problems most often encountered by diabetic men.

Erectile dysfunction has a negative impact on men’s quality of life, regardless of age, and may be an early sign of cardiovascular disease. That is why it is important to talk about it with a healthcare professional.

Risk factors:

  • age
  • how long you have had diabetes
  • poor diabetes control
  • smoking
  • hypertension (high blood pressure)
  • dyslipidemia (for example: high blood cholesterol levels)
  • androgen deficiency (low level of male sex hormones)
  • cardiovascular diseases

Cause

Because diabetes promotes atherosclerosis (fat deposits and hardening of the arteries) and the penis is supplied by very small blood vessels, these vessels are usually the first to be affected. When blood flow is compromised, erectile problems can appear. In addition, poorly controlled diabetes can clog the arteries of the penis and lead to neuropathy, a complication affecting the nerves of the penis.

The psychological aspect of diabetes can also affect sexual function: the shock of the diagnosis, worry about the disease, etc.

Treatment

It is important to consult a physician to be checked for sexual dysfunction and to find the appropriate treatment. Sometimes drugs (Levitra®, Viagra®, Cialis®) will be prescribed.

There are many ways to have an active sex life despite sexual dysfunction. A psychologist or sexologist may be able to help you. Discuss this with your doctor.

Prevention

To reduce the impact of aging and diabetes on your sexual activity and to prevent neuropathy, it is recommended that you:

  • Maintain good glycemic (blood sugar) control.
  • Adopt a healthy lifestyle: stop smoking, maintain a healthy weight, be physically active, avoid excessive alcohol consumption, maintain a harmonious conjugal life with regular sexual activity, learn to better manage stress.
