Many men experience erectile dysfunction (ED); it is a very common condition with approximately half of all men between 40 and 70 experiencing ED to some extent.
Causes for erectile dysfunction can be psychological (for example stress or anxiety), or physical (for example reduced blood flow due to circulation issues such as diabetes, injury to the penis etc.) and ED can sometimes be an indicator of an underlying health issue. Erectile dysfunction can also be related to over consumption of alcohol, drug use or a side effect of certain medication.
