Erectile dysfunction, or impotence, is a condition in which a man feels unable to achieve an erection. The condition is most commonly seen in older people as erectile capacity declines with age. Erectile dysfunction can occur when blood vessels in the penis become narrowed or blocked. Then there is an interaction between the nervous system that “unlocks” the erection. Decreased libido can also be a cause. Blockage or blockage of blood vessels can be caused by certain diseases. These are: diabetes, hypertension, multiple sclerosis, nerve damage, hormonal imbalance, atherosclerosis, and heart disease. An unhealthy lifestyle also predisposes to erectile dysfunction. There is a higher risk of erectile dysfunction with obesity, alcohol abuse, smoking or drug addiction. Some medications can also cause impotence.
