sudden onset

Q All of the following in the medical history suggest that erectile dysfunction is more likely due to organic rather than psychogenic causes EXCEPT:

sudden onset

peripheral vascular disease

absence of nocturnal erections

diabetes mellitus

inability to achieve adequate erections in a variety of circumstances

A careful history will often determine whether the problem is primarily psychogenic or organic. In men with psychogenic impotence, the condition frequently develops rather quickly secondary to a precipitating event such as marital stress or loss of a sexual partner.
