Across the globe, scientists are raising alarm over a silent crisis: men’s testosterone levels are plummeting at a rate that’s both rapid and unprecedented.
A 2007 study revealed testosterone in American men has dropped 1% per year since the 1980s — regardless of age or health. A 22-year-old man today may have lower levels than his grandfather did at 50. And this trend is global.
Testosterone is essential for muscle mass, mental clarity, heart health, libido, and more. Low levels are linked to depression, fatigue, obesity, infertility, and even early death. Experts say this isn’t just a medical issue — it’s a cultural and generational one.
What’s causing this decline? Scientists point to a mix of modern factors: exposure to plastics and chemicals, sedentary lifestyles, poor sleep, ultra-processed diets, and constant screen time. These disrupt hormone production and damage reproductive health.
