Hormones are very important in the aging process because some of their levels decrease. Therefore it can be hypothesized that hormone replacement therapy might slow aging. In light of the increasing interest in rejuvenating treatments that can yield good results, hormone replacement therapy has dawned in scientific circles. This review examines the roles of growth hormones melatonin and dehydroepiandrosterone, as well as those of bioidentical hormones in rejuvenation. The authors have also sought to evaluate the results of studies on hormone replacement therapy, considering the risks and benefits of using those hormones, which are seen as the "fountain of youth."
