Overview
Erectile dysfunction (ED) is the consistent inability to get or keep an erection firm enough for sexual intercourse. While common as men age, it can be a sign of underlying health issues such as heart disease or diabetes.
Understand this condition
An erection occurs when blood fills two chambers in the penis, triggered by nerve signals and chemical releases. For this to work, the brain, nerves, hormones, and blood vessels must coordinate perfectly. If blood flow is restricted or nerve signals are interrupted, the physical response cannot occur.
Why it happens
The condition often results from damaged blood vessels or nerves that prevent the necessary pressure for an erection. It typically progresses from occasional episodes to more frequent occurrences if the underlying health issue is not managed. Stress can further worsen the biological response by triggering chemicals that constrict blood vessels.
