Hormone therapy and anti-aging: Is there an indication?

The desire for a long life is deeply embedded in nearly all men. Fortunately life expectancy has remarkably increased over the past decades, on the other hand advancing age is frequently associated with a rise in morbidity. Above simply prolonging life there is a need to search for strategies to improve the quality of life in the elderly. Different substances to prevent premature aging, cancer and degenerative disorders appear to be promising candidates. Since it has been suggested that the decline of different hormones over the lifespan is closely related to the aging process replacement of these hormones may be a strategy against aging. Especially hormones like growth hormone, DHEA, testosterone and melatonin were considered as anti-aging agents. This review is focusing on the theoretical background and the previously known effects of different hormones to slow aging processes. Despite some promising results in a variety of studies conducted over the past years presently available data do not justify the broad use of hormones for anti-aging purposes. However, although no single hormone can be recognized as a 'rejuvenating' and life extending agent, some of their actions may be beneficial for the aging process. © 2008 Springer Medizin Verlag.
