Episode 62 of The Health Exchange Podcast explores testosterone, hormone optimization, and the evolving field of longevity medicine with guest Christopher Asandra, MD, a physician specializing in anti-aging. Dr. Rutland and Dr. Asandra unpack how testosterone functions at the cellular level, why symptoms like fatigue, brain fog, low libido, and mood shifts matter more than a single lab number, and how individualized treatment can restore energy, muscle mass, and overall quality of life. The conversation tackles common misconceptions about therapy, safety concerns surrounding cardiovascular risk and overprescribing, the importance of proper monitoring, and how fertility factors into treatment decisions. Beyond hormones, the episode broadens into the difference between lifespan and healthspan, examining how sleep, resistance training, nutrition, inflammation, and lifestyle habits intersect with hormone balance to shape long-term vitality. Throughout, Dr. Asandra shares both clinical insights and personal experience, emphasizing a tailored, evidence-informed approach to helping patients not just live longer, but live better.
