What is the Origin of Age-Related Hormone Shift?

This term is rooted in gerontology and endocrinology, acknowledging that aging is fundamentally accompanied by changes in the neuroendocrine axes, a process sometimes termed "somatopause" or "adrenopause." It is a descriptive clinical concept that helps categorize the universal hormonal changes observed in the aging human population. Understanding this shift is central to developing strategies for healthy aging and longevity.

What is the Mechanism of Age-Related Hormone Shift?

Changes in the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes are primary drivers of this shift. For example, a decline in gonadal steroid production, such as testosterone and estrogen, is coupled with altered feedback sensitivity at the pituitary and hypothalamus. Furthermore, reduced target tissue receptor sensitivity, like decreased growth hormone receptor signaling, diminishes the biological efficacy of the remaining circulating hormone levels.

Age-Related Hormone Shift

Meaning

The Age-Related Hormone Shift describes the predictable, gradual, and often non-linear alterations in the production, clearance, and responsiveness of key hormones that occur throughout the lifespan. This physiological decline or imbalance affects the entire endocrine network, leading to clinical manifestations like sarcopenia, decreased bone density, and changes in mood and energy. It encompasses well-documented transitions such as andropause in men and perimenopause/menopause in women.
