Menopause
Menopause, which, by definition, occurs one year after a woman's final menstrual cycle, is normally precipitated by the depletion of ovarian follicles due to aging, although it can also be induced by surgery (hysterectomy), radiation, chemotherapy and health problems.
During this time, hormone levels can fluctuate and change dramatically, causing various biochemical and physiological alterations. Proper measurement of steroid levels is invaluable in managing clinical conditions associated with aging.

Andropause
In contrast to menopause, a clearly defined event for women, aging of the male endocrine system, beginning in middle-aged or elderly men, is a less abrupt, less clearly demarcated and highly variable process.
The free androgen index (FAI), cFT and other measures of free and bioavailable testosterone provide important alternatives to reliance on a Total testosterone measurement alone. They are useful in various clinical contexts including:
• Male androgen deprivation therapy
• Aging males
• Adrenal disorders
• Hirsutism and virilization
Percentage of healthy men with testosterone, FAI and cFT values lower than the 2.5th percentile of the 21–30 year age group.
