Before you start taking drugs or begin any other treatment for ED, your doctor or pharmacist may recommend you to change your lifestyle, for example, they may advise:

Do sports
Follow the diet for reducing blood lipids (fats, holestirola)
Stop smoking
Reduce alcohol
Try decreasing fatigue and worry
Your doctor may also discuss with you the potentially reversible causes of ED, such as the lack of hormones (testosterone), intake of medications that can cause ED.

The method of treatment of ED

Discuss possible treatments with your doctor. Try to learn as much as possible about each method of treatment. Here are some questions that may help you in your decision:

How effective and safe method?
As my wife (or girlfriend) will perceive this method?
Is this method is convenient?
As this method is consistent with my lifestyle?
What is the treatment?
