What is the Origin of Androgen Deficiency Cycle?

The concept stems from clinical observations in endocrinology, particularly in the study of hypogonadism and andropause, where a primary hormone deficiency was seen to trigger a cascade of secondary metabolic and psychological issues. The use of 'Cycle' emphasizes the reinforcing nature of the deficiency and its resultant symptoms. It highlights the systemic impact of androgen insufficiency on overall health.

What is the Mechanism of Androgen Deficiency Cycle?

Low androgen levels often reduce physical activity and contribute to insulin resistance, promoting fat accumulation, especially in the abdominal region. Adipose tissue contains the aromatase enzyme, which converts remaining androgens into estrogen, further lowering the effective circulating androgen concentration. This reduction in anabolic drive and increase in estrogenic signaling exacerbates muscle loss and fatigue, thereby completing the detrimental cycle.

Androgen Deficiency Cycle

Meaning

A self-perpetuating physiological loop where insufficient levels of androgens, such as testosterone and DHEA, lead to adverse health outcomes that, in turn, further suppress the body’s ability to produce or utilize these hormones. This cycle contributes to a decline in lean muscle mass, increased visceral adiposity, and a reduction in energy and libido. Recognizing this cycle is crucial for effective clinical intervention in both men and women.
