http://jn.nutrition.org/cgi/content/full/133/2/516 Here is the chart: http://jn.nutrition.org/content/vol133/ ... 69002.jpeg If you look at serum DHT (picograms per liter), when Soy and Green tea were both given to the mice (test groups of four mice), the levels of DHT fell at least 80% in comparison to the control (ab) group. Black tea reduced the serum DHT by 72% in the mice. However, I dont know the exact distribution of type one and type two alpha five reductase for mice. Perhaps type one is the dominant form in mice? If so, this might not be as much help for us as one would hope. If you look at the total testosterone levels............black tea raised the levels by 34% (good), but the soy/green tea cut them in half in the mice. This would be a "rough" side effect if it translated to men. Side effects would be ......................pretty marked. Prostate tumor weight and serum PSA levels were lowered dramatically with both soy/green tea combinations and especially soy/black tea combinations, as well as black tea by itself . http://jn.nutrition.org/cgi/content/full/133/2/516/F1 ANYBODY GOT ANY IDEA OF WHAT THE ALPHA REDUCTASE DISTRIBUTION IS IN MICE? IS TYPE ONE PREDOMINANT IN THESE CREATURES?
