The hypothalamus is located in the brain. It produces hormones that control or regulate the other structures in the endocrine system. The amount of these regulating hormones stays about the same, but the response by the endocrine organs can change with aging.
Hormones that remain unchanged or only slightly decreased include:
Thyroid hormones T3 and T4, Cortisol, Insulin, Epinephrine, Parathyroid hormone, 25-hydroxy vitamin D, and Testosterone.

One hormone that does not appear to decrease with age is melatonin. Melatonin is a hormone produced by the pineal gland that helps regulate sleep-wake cycles and has antioxidant properties. It tends to remain relatively stable throughout a person's life.
Hormones are released by the endocrine system.
Blood hormone levels are primarily regulated by a complex interplay of feedback mechanisms involving the endocrine glands and the nervous system. Factors such as stress, sleep, exercise, diet, and age can also influence hormone levels. Hormones themselves can also regulate their own production through negative feedback loops.
Typically, the production of growth hormone starts to decline around the age of 30. This decline is gradual and can vary from person to person. By the time a person reaches middle age, the decrease in growth hormone production may become more noticeable.

In some cases, the renal threshold does decrease with age. But not everyone will have a decrease.
Aging produces various structural and functional changes in the nervous system, including: reduction in brain size and weight, reduction in number of neurons, decrease in blood flow to brain, changes in synaptic organization of the brain, and intercellular and extracellular changes in CNS neurons.
