Does a blood test treat erectile dysfunction?

Erections can be affected by blood-vessel health, diabetes, hormone changes, medicines, alcohol, stress, sleep and relationship factors. Depending on your history, a clinician may use blood tests to check glucose, cholesterol, blood count, kidney or liver function, and hormone levels when appropriate. The test helps look for treatable contributors; it does not improve blood flow or create an erection on its own.

Assessment also includes questions about erections, desire, ejaculation, morning erections and medicines, with a blood-pressure check when relevant. Treatment may involve addressing an underlying condition, reviewing medicines, lifestyle support, counselling or an erectile-dysfunction medicine. The safest option depends on your health and other medicines, particularly nitrate medicines.

Book a confidential appointment if erection difficulties continue, recur or concern you. Bring a complete medicine and supplement list, including products bought without a prescription. Tell the clinician whether the problem began suddenly or gradually and whether you have pain, curvature, reduced desire or urinary symptoms. Do not buy unregulated erection products or combine treatments without medical advice.

Arrange prompt review for sudden erectile change with chest pain, breathlessness, weakness or other new symptoms, because the wider health picture may need attention. Seek urgent care for an erection that is painful or does not settle, or for severe allergic symptoms after a medicine. A blood test is not a substitute for assessment of these problems.

Ask which health factors may be contributing, whether hormone testing is appropriate, whether a medicine could be involved, which treatments are safe with your current prescriptions, and when improvement should be reviewed.
