Age Related Axis Decline

Meaning

Age Related Axis Decline denotes the progressive, physiological attenuation of function within a major neuroendocrine axis, such as the Hypothalamic-Pituitary-Gonadal (HPG) or Hypothalamic-Pituitary-Adrenal (HPA) axis, occurring as a consequence of biological aging. This decline is characterized by a gradual reduction in the amplitude and frequency of hormone pulsatility and decreased glandular responsiveness. It is a fundamental process contributing to many clinical manifestations of senescence and reduced hormonal reserve capacity.
