Testosterone Levels in Men Decline Over Past Two Decades, Study Shows

Testosterone levels in American men have been declining steadily over the past two decades, a new study in the Journal of Clinical Endocrinology and Metabolism concludes.

The reasons for this decline are unclear; the study suggests that neither aging nor changes in certain health factors, such as obesity or smoking, can completely explain the phenomenon.

Maybe there's hope for humanity after all.
