Diabetes & sexual health
ED After Diabetes
Erectile dysfunction is significantly more common in men living with diabetes. Understanding why can help patients have a more productive conversation with their physician.
Why diabetes affects erectile function
- Vascular injury — chronic hyperglycemia can damage small and large blood vessels, including those that supply the penis.
- Nerve injury (neuropathy) — diabetes can affect the nerves involved in arousal and erection.
- Endothelial dysfunction — reduced nitric-oxide signaling impairs the relaxation of penile vessels needed for erection.
- Hormonal changes — low testosterone is more common in men with type 2 diabetes and obesity.
- Medication effects — some cardiovascular and psychiatric medications affect sexual function.
What a clinical evaluation typically includes
- Review of diabetes control (HbA1c, glucose patterns)
- Cardiovascular risk assessment
- Testosterone and related hormone testing
- Medication review
- Mental health and relationship factors
Treatment approach is layered
- Optimize diabetes and cardiovascular care first when possible
- Consider lifestyle interventions: nutrition, exercise, sleep, smoking cessation
- Oral PDE5 inhibitors, when medically appropriate
- Second-line therapy: vacuum devices, intracavernosal injections
- Surgical options (penile prosthesis) when other treatments are inadequate
ED in a man with diabetes can also be an early warning sign of broader cardiovascular disease. A coordinated evaluation with primary care, endocrinology, and urology is often appropriate.
Individual outcomes vary. Candidacy and treatment are consultation-dependent.
