Aging is inevitable. As is the fact that testosterone levels fall with age. Peak testosterone levels are seen in early adolescence and early adulthood. Afterwards, there is a gradual decline in the production of testosterone, although men continue to produce quantities of this throughout their lives. The symptoms of aging and low testosterone can often be confused with one another, but here we outline the facts about testosterone levels, aging, and therapy.

Other benefits include increased sexual function, better mood and small positive effect on insulin resistance for men with type 2 diabetes.

Consult your doctor

Risk versus benefits of treatment in the elderly must be assessed. The decision to treat with testosterone replacement should not be a function of what the testosterone value is, but rather how the low testosterone is affecting the individual.  This is a conversation that each patient needs to have with their doctor prior to beginning any therapy.
