Declining Testosterone, calculated free Testosterone, Estradiol, and Estrone levels appear to be associated with muscle mass/strength decline in elderly men. This points to a global decrease in HPA function rather than an individual, specific hormone deficiency.

type and length of training effects testosterone secretion. Testosterone plays an important role in muscle performance and mass. Prolonged training can result in a decrease in testosterone level. This has significance with highly trained athletes. One pitfall of this study was the assessment of testosterone via serum.

Testosterone therapy is complex in hypogonadism. Much of the marketing-based medicine of Low T today is in fact doping. Increasing weight is clearly associated with a declining T level in men. Testosterone therapy should be approach individually and therapies that use the one size fits all approach never work. This is the case whether the use of synthetics or natural hormones are employed. Testosterone has been shown to improve dysglycemia, MetS, reduce fat and increase muscle mass.
