What if one of the most important health crises affecting men today wasn’t being caused by aging—but by the environment we live in?

In this eye-opening solo episode, Darin Olien investigates the alarming decline in testosterone levels, fertility, and reproductive health among men worldwide. Drawing on decades of research, epidemiological studies, environmental science, endocrinology, and public health data, Darin examines the growing evidence connecting endocrine-disrupting chemicals, microplastics, sleep deprivation, chronic stress, poor lifestyle habits, and environmental toxins to declining testosterone levels across generations.

From BPA, phthalates, atrazine, PFAS, and microplastics to sleep quality, circadian rhythms, cholesterol metabolism, cortisol regulation, and natural testosterone-supporting strategies, this episode explores what may be one of the most underreported public health issues of our time—and what men can do to take control of their health today.
