    The Importance of Hormone Testing

    LifeXMD.com - Jan 15, 2012 - Millions of aging men have the dual conditions of low testosterone and high cholesterol. Conventional physicians prescribe cholesterol-lowering drugs to reduce cholesterol, when, in fact, the age-related rise in cholesterol might simply be the body’s way of increasing hormone levels by supplying the raw materials necessary to make hormones (Dzugan et al 2002). Researchers at the Life Extension Foundation have successfully treated high cholesterol levels through a program of bioidentical hormone replacement therapy.

    The Life Extension Foundation believes that comprehensive tests, along with a careful physical examination, are essential in detecting hormonal imbalances in aging men.

    The so-called “normal” levels of testosterone in older men reflect population averages. The Life Extension Foundation believes that most aging men would prefer not to accept the loss of youthful vigor as normal. Instead, we suggest that a more valid optimal level for all men would be in the upper one-third of the reference range used for men aged 21 to 49 years, and that any supplementation should aim to restore hormone levels to that range. The current Life Extension optimal level of free testosterone is 20-25pg/mL.

    When measuring testosterone levels, it is critical to determine the levels of both free and total testosterone to understand the cause of any observed symptoms of deficiency (Khosla et al 2008).

    Because of difficulties with equipment standardization and inter-laboratory variability, it is recommended that physicians consistently use the same local laboratories and gain familiarity with the accuracy, precision and definition of normal values for the assays offered in their communities (Morales et al 2010).

    It is also important to remember that blood levels of both free and total testosterone vary widely among individuals, making it difficult to establish a general baseline on which to prescribe a standardized treatment protocol. However, levels are quite consistent within individuals, and thus it is important that men have multiple tests over time to determine trends and individual thresholds for treatment.

    Finally, during the initial testing, it is also imperative to test estrogen levels. Many of the unwanted effects of male hormone imbalance are actually caused by an elevated estrogen level relative to low testosterone levels (the estrogen/testosterone ratio). The Life Extension optimal level of estrogen (measured as estradiol) for aging men is 20-30pg/mL.
