| Hormones Can Differentiate the Sexes
The hypothalamus takes the
first necessary steps to bring males and females to
the stage of puberty by sending the Gn-RH hormone (Gonadotropin-releasing
hormone) via the bloodstream to the pituitary gland.
The pituitary gland begins its function on the command
of the hypothalamus and starts to send hormones which
will activate the reproductive organs. These are the
LH (luteinizing) hormone and the FSH (follicle stimulating)
hormone. Each of these hormones is secreted in both
men and women, but their effect is different.

The hypothalamus causes the production of sperm
in men (left) in cooperation with the anterior lobe
of the pituitary gland and the testes. The hormoneproduction
in women (right) involves the hypothalamus, the
pituitary gland and the ovaries. These biochemical
operations particular to men and women demonstrate
the existence of an intelligent design and plan. |
In spite of the fact that the same hormones are secreted
in both men and women, it is most surprising how totally
different their effects are. For example, in women,
the FSH hormone stimulates the production of the egg;
in men, the same hormone stimulates the production of
the sperm. In women the LH hormone ensures that the
egg is discharged on its way to the uterus and that
another hormone called progesterone is secreted by the
female reproductive system. Progesterone is used to
prepare the uterus for the baby. The same hormone performs
a totally different function in men, stimulating the
cells for the secretion of the testosterone hormone.
Testosterone produces the male characteristics and assures
the production of sperm.

| In this illustration we see the
molecular and crystallized structure of the progesterone
hormone (1), and below, we see the molecular and
crystallized structure of the oestrogen hormone
(2). It is evident that these hormones, composed
of a few atoms, cannot, by their own will, plan
the changes that take place in the human body. It
is Almighty God Who created them and gave them their
wondrous functions. |
| Have
they not looked into the dominions of the heavens
and the earth and what God has created, and seen
that it may well be that their appointed time
is near? In what other revelation will they believe,
those that deny this? (Qur'an, 7: 185) |
It is certainly interesting to consider that same hormones
are produced in different bodies according to the same
formulas but cause results which are totally different
from one another.

DNA contains all the information relative to
a human being and is found in the nucleus of every
one of the approximately 100 trillion cells in
our body. Within a cell, DNA is organized into
dense protein-DNA complexes called chromosomes.
In the illustration on the right, it can be seen
how chromosomes are packed in the cell. The design
in DNA is one of the best examples of the perfection
of God's creation. |
When a hormone is secreted in a male body, it knows
that it belongs to a male and makes the appropriate
changes. For example, testosterone causes the development
of muscles in the male body, it makes the voice deeper
and the beard grow.
The same hormone is secreted in the female
body according to the same formula but, in women, it
causes almost totally opposite results. A hormone that
gives a female voice to a woman and a male voice to
a man and that can adjust the development of the body
according to the sex, is a hormone that can distinguish
between the anatomy and chemistry of a male and female
body. The fact that a hormone possesses such knowledge
means that it has intelligence and must have received
instruction.
Many people do not even know about the influence of
hormones on the male and female reproductive organs,
the inter-relations among the cells or how the bodily
functions have been put into operation. They have no
idea of the body's chain of command, the sending and
delivering of the messages, that the development of
the body depends on these commands, and that the slightest
hitch in the functioning of the system can have fatal
consequences; nor do they have any control over this
functioning. It is not at all unusual for a person who
has not had special training in this field to be unaware
of these things, but the fact that a group of molecules
has this knowledge is incredible.
How do the hormones, seen below with their molecular
structures, come into being and be in possession of
chemical information? How is it that, not content just
to know the chemistry of the body, each one, like a
chemist, uses the knowledge it possesses, applying it
to the areas of the body where it is required? How do
they direct other cells to produce the requisite hormones
at the time they are required? How can this unconscious
mass of molecules have the intelligence to do all these
things? It is clear that the molecules called hormones
cannot have this intelligence. It is evident that all
these processes could not come about by chance by any
other such random operation.
There is only one explanation for this: the biochemical
processes by which males and females are given their
separate characteristics show the existence of a deliberate
plan and design. This design is the work of the supreme
intelligence of God. What a human being must do is to
think very deeply about this flawless art and to submit
to the Lord Who is the supreme ruler of everything.
