What is the Origin of Pharmacological Androgen Deprivation?

This therapy originated in the field of oncology, specifically following the work demonstrating the androgen dependence of certain tumors. The term "deprivation" accurately describes the clinical goal of removing the stimulatory effect of androgens on target tissues.

What is the Mechanism of Pharmacological Androgen Deprivation?

The mechanism of action involves various classes of drugs, including Luteinizing Hormone-Releasing Hormone (LHRH) agonists or antagonists, which suppress testicular androgen production, or anti-androgens, which block the androgen receptor at the cellular level. This systemic reduction in androgen signaling leads to predictable side effects, including loss of muscle mass, decreased bone density, and metabolic dysregulation, highlighting the essential role of androgens in maintaining physiological homeostasis.

Pharmacological Androgen Deprivation

Meaning

Pharmacological Androgen Deprivation refers to the medical intervention of deliberately suppressing the production or blocking the action of androgens, such as testosterone and dihydrotestosterone (DHT), using specific drug agents. While primarily used in oncology to treat androgen-sensitive cancers like prostate cancer, its understanding is crucial in hormonal health to recognize the profound systemic consequences of sex hormone withdrawal. This is a powerful intervention with significant endocrine and metabolic side effects.
