Three common ways ED appears
A person may get an erection only sometimes, lose firmness before sex is complete or be unable to get an erection. Desire, orgasm and ejaculation are separate concerns that should also be mentioned when relevant.
Why the cause is not always obvious
Blood vessels, nerves, hormones, medication effects, stress, sleep and relationship context all influence erections. One online answer cannot establish which factor is most important for an individual.
What an assessment looks for
A clinician reviews symptom timing, morning erections, cardiovascular and metabolic health, medications, substance use and mental health. Blood pressure, examination or laboratory testing may be recommended.
