vymarex com What causes erectile dysfunction? How does an erection happen? The veins that allow blood to leave the penis are only so wide. During an erection, the blood vessels that let blood into the penis relax and widen (dilate). This lets more blood in – more than can escape – which causes the sponge-like tissues of the penis to swell and harden. Complex biological mechanisms are involved in allowing these blood vessels to relax and redirect blood to the penis. Your thoughts and senses (touch, hearing, smell and sight) influence a part of the brain that can trigger an erection. In addition, hormones and other substances determine how your nerves transmit ‘sexual signals’ and how blood vessels respond to the received signals. Arousing thoughts or nervous mechanisms (eg, touch reflexes) are two ways an erection is initiated. What causes an erection to fail? Erectile dysfunction occurs when sexual stimulation or arousal (you may still ‘have the urge’) does not result in sufficient blood flow to the penis. For most men there is a physical or medical reason for this, for others the problem is related to thoughts or emotions. Even when there is an initial physical reason, a man may still feel anxious about having sex, and this can compound the problem. Physical & medical reasons Recent illness, such as a heart attack, or injury to the brain or spinal cord, can be a cause. Many other medical conditions can also lead to nerve damage or reduced blood supply to the penis – the most common of these is diabetes (men with diabetes are much more likely to have problems with erections). Other factors that can reduce blood flow to the penis include: excess alcohol smoking use of social drugs such as marijuana, cocaine narrowing of blood vessels caused by a high blood cholesterol level medications - wide range such as in Table 1. Any concerns, discuss with your doctor for possible alternatives.
