In this video excerpt, Dr. Anne Truong examines a case of a 78‑year‑old male whose total testosterone measures 864 ng/dL, placing him in the top 10 percentile of the normal range (300‑900 ng/dL) and achieved without any testosterone replacement therapy. She interprets this high level as an indicator of relatively good health and activity. However, the patient continues to experience erectile dysfunction (ED). Dr. Truong questions why ED persists despite adequate or elevated testosterone, highlighting that testosterone alone does not guarantee erectile function. She suggests that other factors—vascular insufficiency, neurogenic issues, psychological components, comorbidities, or medication effects—must be considered, emphasizing a comprehensive diagnostic approach that looks beyond hormone levels.

In fact, at 78 years old, his total testosterone is 864. That's pretty at the top 10 percentile because testosterone runs from 300 to 900 nanograms per deciliter, and he's at the high 800. So he's up there, and this is without testosterone replacement therapy. So that tells me that he's fairly active, He's fairly healthy. That's why his testosterone level is high, but yet he still has ED. Why does he have ED?
