A regular alcohol addict may experience negative effects on health for good. A sudden intake of alcohol may cause temporary erectile dysfunction, which is corrected automatically as the effects of alcohol subsides.

However, long-term alcohol addiction may cause permanent erectile dysfunction. Long-term effects are manifested in two ways.

1: Down-regulation of the autonomic nervous system

Chronic alcohol addiction to heavy alcohol consumption badly affects your autonomic nervous system, which controls autonomic function in the body, including unconscious activities. The most common side-effect of chronic addiction to alcohol is erectile dysfunction, which may be long-term.

2: Damaged blood vessels

Mild alcohol consumption does not lead to cardiovascular disease. However, heavy alcohol intake for a long period may lead to erectile dysfunction caused by damaged blood vessels and cardiomyopathy. A study suggests that alcohol consumption leads to damaged blood vessels and high blood pressure, a risk factor for sexual dysfunctions.

Abnormal blood pressure leads to decreased blood circulation toward the penis, making it difficult to erect the penis adequately.

Other side-effects on sexual health

Alcohol not only contributes to erectile dysfunction but also has some other negative effects on sexual health as:

  • Delayed ejaculation or orgasm
  • Low sex drive
  • Vaginal dryness in women
  • Shrinkage of penis


Alcohol intake leads to erectile dysfunction through altered neurotransmitter activity in the brain, decreased hormonal levels, and damaged blood vessels.

It’s therefore important to ensure that you aren’t drinking too much alcohol as it can lead to disruption to your sexual activity, particularly if you drink frequently over a long period.

If you have erectile dysfunction, there are many ways to solve it including different clinics, methods and solutions.
