In fact we keep seeing it mentioned about how much our T declines to levels of women with menopause. But in theory it's the E and even PM, that we should get the benefits from of bone loss.
Controlling DHT would still be the logical course. But we still need T at some level to convert to E.
Interesting!, thanks for sharing. 
Lotus, are you saying that I should still attack my DHT with a daily dose of Pygeum, but forget the Spearmint? Am I correct in my understanding that the total serum testosterone measurement does not include DHT?
Clara 
Yes, IMO.
This might get confusing, sorry didn't have time to wrap it up in a nice bow, so this will have to do. (FYI-for Clara) or those who want to know!
*One test measures the total amount of testosterone in the blood. Another test measures what is called "free" testosterone.
*Testosterone is present in the blood as "free" testosterone (1-4%) or bound. testosterone (~98%). 98% of T is considered unbound
*Typically, a test for total testosterone is used for diagnosis. The total testosterone test measures testosterone that is bound to proteins in the blood (e.g., albumin and sex-hormone binding globulin [SHBG]) as well as testosterone that is not bound. However, a test for free or bioavailable testosterone may be used if, for example, the level of SHBG in the blood is abnormal.
*Measurement of the serum total (free plus protein-bound) testosterone concentration is usually an accurate reflection of testosterone secretion and is the initial test of choice.
*If serum free testosterone is measured, the following points should be kept in mind:
*Serum free testosterone should be performed by equilibrium dialysis and only in those few laboratories that specialize in endocrine testing.
The free testosterone concentration, as calculated from the total testosterone, SHBG, and albumin concentrations, may also be reliable, but there are many different equations for this calculation and they give vastly different results, some of which reflect the results obtained by equilibrium dialysis better than others. Consequently, it is essential that the result be compared with the normal range for the laboratory that performed the assay.
*Free testosterone measured by an analog method, which is the assay most commonly offered by hospital and commercial laboratories, does not correlate with the results of equilibrium dialysis. This test gives misleading information and should never be ordered.
*DHT (DiHydroTestosterone) is formed when testosterone is broken down by the enzyme 5-alpha-reductase.
*The latter may be loosely bound to albumin (38%), the main protein in the fluid portion of the blood, or bound to a specific binding protein called Sex Hormone Binding Globulin (SHBG) (60%), also called Sex Steroid Binding Globulin (SSBG).
*The binding between testosterone and albumin is not very strong and is easily reversed, so the term bioavailable testosterone (BAT) refers to the sum of free testosterone plus albumin-bound testosterone.
