Dr. Brian Lawenda (through podcasters) examines the significant decline in testosterone levels among men today compared to the 1980s. This decrease is attributed to poor diet, sedentary lifestyles, environmental toxins, stress, and insufficient sleep. The podcasters highlight the health consequences of low testosterone, including increased risks of obesity, diabetes, and cardiovascular disease. It emphasizes the importance of measuring free testosterone, not just total testosterone, for an accurate assessment of hormonal health. Finally, they discuss various medical interventions for low testosterone, including testosterone replacement therapy (TRT) and other options, along with lifestyle changes that can improve testosterone levels.
