THE MIRACLE OF HUMAN CREATION

The Sertoli cells have additional functions such as protein production.
This protein will carry the oestrogen and testosterone hormones to a fluid
found in the seminiferous tubules. 5
And the Leydig cells also have a second function. In order for the
sperm cells to move, they require energy; the Leydig cells supply this en-
ergy by the fructose they produce. (This important topic will be dealt with
in more detail later.)
As we can see, as in other parts of the body, the hormonal system also
performs in a perfectly organized fashion in the reproductive system. Every
hormone immediately understands the message carried by another and
responds as required. For example, the pituitary gland, when it knows the
time is right, goes into action and sends commands to various cells in the
testes informing them of the job they must do in the organs and tissues. Mo-
reover, what stimulates the pituitary gland into activity is a different area of
the brain called the hypothalamus.
The first stage of the formation of a human being is concerned with the
correct understanding of the messages hormones carry and with the proper
execution of the commands. How do cells and molecules discern and react
to messages carried by hormones? How do they know the chemical make-
up of each one and what methods must be employed to affect them?
The fact that, in order to support the production of sperm, the Sertoli
and Leydig cells go into action at the command of the pituitary gland (a
gland very distant from them, which they have never seen and which has

a totally different structure from their own) combined with the fact these
cells would not perform any function at all without these commands, ma-
kes it impossible to explain their activity in terms of chance. It is impossib-
le that hormones have gained their special characteristics as a result of a
series of chance occurrences, because a severance or an interruption during
one stage of the system will influence a whole chain of processes. If one ele-
ment in the system is defective, the functioning of the whole system is im-
paired. For example, if the Sertoli cell does not know the meaning of the
FSH hormone sent by the pituitary gland and does not begin to secrete oest-
rogen, sperm cannot be produced. Or, if the Leydig cells cannot perform
