Erectile disorder (ED) refers to a persistent difficulty achieving or maintaining an erection sufficient for satisfying sexual activity. It affects millions of men worldwide, including up to one in four in the United States. Beyond physical functioning, erectile difficulties can impact sexual confidence, self-esteem, relationship satisfaction and quality of life.
Although prevalence increases with age, age alone does not explain ED. Medical conditions such as diabetes, cardiovascular disease and the after-effects of surgery (prostate surgery particularly) can disrupt erectile functioning.
Psychological contributors are also common. Performance anxiety, stress and relational concerns frequently cause ED or interact with biological factors, making ED a complex condition, not a single, isolated problem.
