Does testosterone really fall with age?

The short answer

Yes, slowly: about 1 percent a year after 30 to 40. Most of the steeper drops are caused by weight, illness, medication, and poor sleep, not by age alone.

There is no male menopause. Healthy, lean older men often keep testosterone levels close to those of younger men. That matters, because it means a low reading is frequently a symptom of something else that can be fixed.
