In this brief clinical vignette, Dr. Anne Truong presents the case of Joe, a 70‑year‑old married man who is generally healthy, standing 5'9" and weighing 165 lb, and exercising four days per week. He has borderline diabetes and has experienced erectile dysfunction (ED) for approximately six years. While he can achieve an erection, maintaining it is difficult. Joe explicitly declines pharmacologic treatments (e.g., PDE‑5 inhibitors) and mechanical options such as a vacuum pump, preferring instead to understand the underlying cause of his ED and restore sexual intimacy with his wife.
