What is the Origin of Testosterone Reinstatement?

The concept of hormonal replacement therapy dates back to the early 20th century, but the term "reinstatement" reflects a modern, nuanced clinical goal of restoring the hormone to a youthful, optimal functional level, rather than merely achieving a minimum reference range. This shift is driven by a focus on longevity and quality of life.

What is the Mechanism of Testosterone Reinstatement?

Reinstatement operates by administering exogenous testosterone, via various routes such as injection, transdermal gel, or pellet implant, to supplement the body's endogenous production. The therapeutic mechanism involves the hormone binding to androgen receptors in target tissues, modulating gene expression to restore muscle mass, bone density, libido, and cognitive function, all while closely monitoring the estradiol and hematocrit levels.
