In this brief segment, Dr. Anne Truong MD explains that after age 30 men experience a steady decline in testosterone of about 1–2% per year, resulting in a 30–40% reduction by the time they reach their 50s or 60s. She links this hormonal drop to a cluster of mid‑life symptoms: reduced energy, weight gain, loss of muscle mass, increased belly and chest fat, brain fog, weaker erections, and lower libido. The clip serves as a concise medical overview of how age‑related testosterone loss drives common health concerns for men in their 40s and beyond.
