Androgen Excess and Deficiency
Androgen Excess and Deficiency
Analysis of Androgen Regulation and Imbalance Effects
Androgen Regulation Axis (HPT Axis)
The production of androgens (primarily Testosterone) is a strictly regulated process known as the Hypothalamic-Pituitary-Testicular Axis. This system uses a series of hormonal signals and negative feedback mechanisms to ensure androgen levels remain in a stable balance.
Hypothalamus
Gonadotropin-Releasing Hormone (GnRH)
Pituitary
Androgen Deficiency
When Testosterone secretion is insufficient or its conversion pathways (e.g., reductase) are blocked, the body tends to exhibit diminished male characteristics or feminization. This affects the reproductive system, secondary sexual characteristics, and metabolic distribution.
The radar chart below illustrates the spectrum of typical traits in Androgen Deficiency, showing multiple systems are affected, generally trending towards feminization and hypogonadism.
Androgen Excess
When the body produces excessive androgens (e.g., due to tumors or adrenal conditions), it leads to an over-expression of male characteristics (Virilization), burdening multiple physiological systems.
This bar chart highlights the most prominent physiological changes. In females, these effects are especially pronounced, such as voice deepening, beard and chest hair growth, and amenorrhea.
