There are a number of potential causes of ED for men of nearly all ages, but the chances of developing ED increase as a man ages. Causes of ED can include the following: 

  • Certain medications: Chronic illness, such as diabetes or multiple sclerosis    
  • Excessive alcohol consumption  
  • Obesity
  • Poor blood flow
  • Chronic stress

Conclusions: Like many medical conditions, there is not necessarily only one means to cure or reduce symptoms of ED. For men wishing to avoid the use of medication, there are a number of lifestyle changes that can be tried first, followed by some potential natural remedies and additional therapies. It is important for any man suffering from ED to consider lifestyle changes and talk to a doctor before starting new medications, herbal remedies, or stopping a prescription medication suspected of causing ED.
