Furthermore, one cannot make general statements about potencies of estrogens, especially since each estrogen is potent for a specific metabolic end-point. Finally, it should be pointed out that modern endocrinology leans heavily upon biochemistry and mechanisms of actions. In both of these respec...

Now this is an extremely important microbiological concept for which one w...
