The endocrine system is made up of organs and tissues that produce hormones. Hormones are natural chemicals produced in one location, released into the bloodstream, then used by other target organs and systems. Some organ systems have their own internal control systems along with, or instead of, hormones. As we age, changes naturally occur in the way that body systems are controlled. Some target tissues become less sensitive to their controlling hormone, the amount of hormones produced may also change. Many of the organs that produce hormones are, in turn, controlled by other hormones. Aging also changes this process. For example, an endocrine tissue may produce less of its hormone than it did at a younger age, or it may produce the same amount at a slower rate.
The hormone or endocrine theory of aging asserts that the most important factors in aging are the changes brought about in the body by the endocrine system. The complex endocrine system of our body controls the hormones that regulate many body processes. As we age, these systems become less efficient, leading to changes in our bodies such as menopause. The hormone theory of aging believes that these changes eventually cause the effects of aging.
Hormonal changes are an important part of aging. Whether they control the pace at which aging happens or are a consequence of other changes in the body is unknown. It is unlikely that hormone substitution in humans will increase lifespan and can even be dangerous. Some anti-aging doctors will prescribe human growth hormone (HgH), but research does not show that this helps with aging.
Testosterone is a hormone that plays a large part in the development of male secondary sexual characteristics as well as helping to regulate bone mass, fat distribution, muscle mass and strength. Testosterone production peaks in adolescence and early adulthood. After that, testosterone levels slowly decline. However, throughout life most men produce large quantities of testosterone.
A lot of things we think are due to testosterone deficiency are actually related to the estrogen deficiency that accompanies it. Testosterone is the main male sex hormone. Men’s bodies convert some of it into estrogen, and levels of both decline with age. Until now, there was no way to tell which hormone was responsible for complaints of diminished libido, strength and energy. Some people call this midlife decline “male menopause” although men don’t menstruate and testosterone doesn’t fall off as sharply with age as estrogen does in women after menopause. ”Andropause would be more reasonable,” since testosterone is an androgen, a male sex hormone.
Doctors and fitness professionals still have a lot to learn about exercise and its effects on testosterone. Several factors besides your workout are involved. But one thing is clear, you need to make exercise a habit in order to get the benefits.
