Erectile dysfunction (ED) is the persistent or recurrent inability to obtain or maintain an erection sufficient for sexual activity. ED can have a major impact on the quality of life and self-esteem of men suffering from it and often affects the relationship with their partners.
Epidemiological evidence has shown that about 52% of men between 40 and 70 years of age have fairly marked erectile problems that affect sexual activity1.
Affecting a population which is still sexually active at a high percentage even at the age of >70 years, ED further contributes to a decreased quality of life2.
Erection problems mainly result from:
- Stress, anxiety and depression
- Cardiovascular disease
- Diabetes (vascular or neurological problems)
- Smoking (exacerbates vascular problem)
- Prostatectomy (neurological problems)
- Medications or illicit substances
