what causes impotence
Impaired blood flow to the penis. A very common cause of impotence is when blood flow to the penis is impaired due to atherosclerosis, also known as hardening of the arteries. In atherosclerosis, the arteries are clogged and narrowed, resulting in reduced blood flow.
Performance anxiety can be another cause of impotence. If a person wasnât able to achieve an erection in the past, he may fear he wonât be able to achieve an erection in the future. A person may also find he canât achieve an erection with a certain partner.
