What is the Origin of Gonadal Steroid Replacement?

This practice is foundational to endocrinology, stemming from early discoveries regarding the effects of testicular extracts and ovarian hormones on secondary sexual characteristics and vitality. It addresses deficits in the sex hormone arm of the endocrine system.

What is the Mechanism of Gonadal Steroid Replacement?

Replacement works by bypassing insufficient gonadal output, thereby saturating peripheral and central steroid receptors. This action supports anabolic processes, maintains secondary sexual characteristics, regulates reproductive function, and influences mood and cognition via genomic and non-genomic signaling pathways. Precise dosing is required to avoid negative feedback loops or aromatization issues.

Gonadal Steroid Replacement
