What is the Meaning of Testosterone Replacement Therapy?

Testosterone Replacement Therapy (TRT) is a formalized medical protocol involving the regular, prescribed administration of testosterone to treat clinically diagnosed hypogonadism. This therapy seeks to alleviate symptoms associated with androgen deficiency by normalizing serum testosterone levels within the optimal physiological range, supporting anabolic function, energy, and sexual health. It is a highly individualized treatment strategy requiring ongoing biochemical monitoring.

What is the Origin of Testosterone Replacement Therapy?

This is a formal medical term combining the hormone being supplemented, 'Testosterone,' with 'Replacement Therapy,' which describes the systematic medical delivery of a deficient substance. Its structure indicates a therapeutic intervention rather than a temporary measure.

What is the Mechanism of Testosterone Replacement Therapy?

TRT operates by delivering exogenous testosterone via various routes—transdermal, injectable, or pellet—to elevate circulating levels, thereby activating androgen receptors globally. A key consideration is the negative feedback mechanism, where exogenous testosterone suppresses endogenous LH and FSH production, effectively halting native testicular function. Successful implementation requires balancing symptom relief with minimizing unwanted side effects like erythrocytosis or aromatization to estrogen.
