he plan behind the creation of the testosterone goes much fur-
ther than this. An evident miracle of creation can be seen in the
mechanism of this hormone's effects. In order to have the effects listed be-
fore, when the testosterone reaches the targeted tissue (the male genitalia)
it enters the cells there. Inside the cells, it combines with an enzyme spe-
cially created for testosterone, which thus assumes a far more effective
state.
The design and planning are still not finished. This newly formed hor-
mone now combines with a receptor specially designed for it. The emer-
gent molecular combination binds to the cell's DNA, and in the light of
information it receives from the DNA, a new protein synthesis is created.
This permits the determination of the difference between the male and fe-
male sexual characteristics, as well as the beginning of sexual functions.
This system is so perfectly designed that the mechanism—consisting
of the testosterone, enzyme and receptor—locates the information encoded
for it from among all the billions of pieces of data in the DNA and allows
production to be made according to that information. For example, in order
