What is ED?
ED is a man's inability to get or sustain an erection. An erection is caused by signals from the brain to the nerves in the penis, resulting in increased blood flow. The tissue in the penis begins to expand and harden as a result of this signal. That means any issue which interferes with the nervous system could lead to ED.
It is estimated that up to half of men aged 40 to 70 suffer with ED. However, it is hard to pinpoint an exact figure as many males are too embarrassed to talk about the issue. With so many men potentially experiencing ED, however, it seems there is little reason to feel alone.
