ENDOCRINE RESPONSES TO EXTREME ENVIRONMENTAL STRESSORS

A critical review of contemporary scientific literature provides insight into current understandings of the functional alterations occurring within endocrine regulatory systems under the influence of diverse environmental stressors. Numerous studies indicate that the hypothalamic–pituitary–gonadal (HPG) axis and the thyroid axis, in conjunction with the sympathoadrenal system and the hypothalamic–pituitary–adrenal (HPA) axis, represent key regulatory pathways involved in the organism’s response to extreme environmental conditions and adaptive physiological processes. These interconnected endocrine systems participate in maintaining internal stability through coordinated hormonal responses. In the context of systemic homeostasis, fluctuations in hormonal secretion are manifested as a complex cascade of tightly integrated regulatory reactions that collectively ensure adaptive responses to external stress factors. Such endocrine adjustments play a critical role in coordinating metabolic regulation, neuroendocrine signaling, and adaptive physiological mechanisms necessary for survival under stress conditions. Despite significant advances in the field of endocrinology, the comprehensive elucidation of these regulatory mechanisms and their contribution to the pathogenesis of stress-induced disorders remains a major challenge in contemporary biomedical science. Further investigation of these processes is essential for improving the scientific basis of preventive and therapeutic approaches aimed at mitigating stress-related pathological conditions.
