In this educational video, Dr. Anne Truong highlights a common problem: many men with erectile dysfunction (ED) self‑medicate by obtaining prescriptions online without consulting a physician, leaving the underlying cause unidentified. She explains that ED is multifactorial and outlines five broad categories of causes: (1) vascular or blood‑flow problems that limit penile blood supply; (2) nerve or neurological issues that impair signaling; (3) hormonal imbalances such as low testosterone; (4) psychological factors including stress, anxiety, or depression; and (5) medication side‑effects or lifestyle choices like smoking, vaping, lack of exercise, and obesity. The video aims to raise awareness that proper diagnosis is essential before treatment.
