Page 131 - The Miracle of Hormones

Testosterone affects the vocal cords causing a male voice to be lower
than that of a woman. In addition, the testosterone molecule gives the
male body its ability to fertilize the female egg.
Certainly it is surprising that an unconscious molecule can do all
this. This molecule knows the particularities of the male body and directs
trillions of cells in the formation of this body.
Testosterone molecule is not limited to these things. Clear evidence
of design can be seen in the mechanism by which this hormone exerts its
influence. In order to bring about its effects, testosterone reaches the tar-
geted tissues (the male genital organs) and enters the cells. Inside the cell,
it unites with an enzyme specially created for it whereby its effects are
greatly increased.
This newly formed hormone then unites with a special receptor de-
signed specially for it. The resulting molecular combination unites with
the cell's DNA and uses the information received from the DNA to bring
about a new protein synthesis. This operation ensures that the distinction
between male and female bodies, and their different sexual functions,
will continue.
