The purpose of bio-identical hormone replacement therapy is to restore hormone levels to those seen in youth, thus recovering lost function, and thereby gaining health benefit. The aging process proceeds through several drivers, one of which is the decline of hormones seen in the 40's and 50's.
This age-related collapse of ovarian and testicular hormone production results in the symptoms of menopause (and andropause in the case of males).
The decline of hormone production is related to the onset of diabetes, heart disease, osteoporosis, cancer, and cognitive decline.
