Erectile problems become more common as men age, but NIDDK emphasizes that ED is not a routine or inevitable part of aging. After 40, the chance that cardiovascular, metabolic or medication-related factors contribute becomes increasingly important.
NIDDK reports that ED becomes more common with age while also stressing that aging itself is not a complete explanation. Health conditions that accumulate over time—such as diabetes, obesity, high blood pressure and vascular disease—are important contributors.
An erection depends on blood vessels responding properly. High blood pressure and atherosclerosis can impair that system. This is one reason persistent ED can be a useful prompt to review cardiovascular risk rather than treating it as an isolated bedroom issue.
Low testosterone can contribute to ED and low libido in some men, but symptoms alone do not diagnose testosterone deficiency. Several commonly used medicines, including some blood-pressure drugs and antidepressants, can also affect erections. Never stop a prescribed medicine on your own; ask the prescriber whether an alternative is appropriate.
Evidence-based treatment may combine risk-factor management, lifestyle changes, counseling when relevant and prescription ED medications such as PDE5 inhibitors. The right approach depends on medical history, other medicines and the suspected cause.
No. ED becomes more common with age but is not considered a routine or unavoidable part of aging.
Yes. High blood pressure, atherosclerosis and other cardiovascular conditions can contribute to ED because erections depend on healthy blood flow.
