Known best as the "sex drive" hormone in men, testosterone levels in men decrease gradually over time, due to factors such as reduced activity, nutritional deficiency, diabetes, and HGH deficiency.  This phenomenon is sometimes referred to as andropause.  By age 60, many men have less than half the level of testosterone as they did when they were in their teens.

While testosterone replacement therapy (TRT) can improve erectile function and libido, testosterone is one of the most important anti-aging medications because it  it also has a multitude of additional and noteworthy benefits, including to:

• Increase lean body mass

• Decrease fat mass

• Improve cholesterol profile, including to decrease "bad" cholesterol (LDL)

• Reduce bone fractures

• Improve cognitive functions, including visual spatial perception

• Improve mood, including remission of depression
