Abstract　： [Introduction] The endocrine system, as well as the nervous system and circulatory system, has important roles to play in the maintenance of the homeostatic functions. An understanding of age-related changes in the endocrine function can make a significant contribution to the time-related physiologic alteration and to the aging process. The constant concentration of a hormone in blood does not necessarily mean that age has been unaccompanied by physiologic changes. The blood level of a hormone is the balance of a number of processes, each of which can be age-influenced. The concentration of a hormone with a relatively constant rate of production results not only from the rate of secretion but also from the concentration of specific carrier binding proteins in plasma, which determine the "free" or metabolically active hormone in plasma and the rate of metabolic destruction or disposal of the hormone, metabolic clearance rate (MCR). Moreover, the blood hormone levels are ultimately related responsively of the target tissue to the hormone.
