About Erectile Dysfunction.
Erectile dysfunction, or ED, is the inability to achieve or sustain an erection suitable for sexual intercourse. Causes include medications, chronic illnesses, poor blood flow to the penis, drinking too much alcohol, or being too tired.There are two categories of ED: Physical ED and Psychological ED. Physical ED may result from damage or deterioration to nerves or blood vessels of the penis. It may also be caused by problems with hormones like Testosterone or might be as a result of a more significant underlying medical issue. Many drugs, and alcohol, uncontrolled diabetes and smoking to name a few, can damage arteries and cause ED as a side effect. Nerves damaged by spinal cord injuries, multiple sclerosis, or surgery can also give rise to erection difficulties. Psychological or emotional ED arises from fear, stress, worry, anger or frustration. It may also develop from “performance anxiety” (a man’s fear that he won’t perform well during sexual intercourse), or from the embarrassment of premature ejaculation.
