Hormones That Are
Able to Regulate Time and Produce the
Differences Between the Sexes
We all have a biological clock within
us-this expresses the idea that there are a number of
micro-clocks in various regions of our bodies programmed
to regulate time. One of these micro-clocks is located
in the hypothalamus area of the brain.9
Human beings go through a period of adolescence between
childhood and adulthood when the body experiences many
definite changes. Girls enter adolescence between the
ages of eight and fourteen, boys between the ages of
ten and sixteen.
This clock that never goes wrong has been placed in
the bodies of the countless human beings that have been
created until today. How can this clock understand without
error that a person has come into adolescence?
One hypothalamus area of the brain has been waiting
for years since the time of birth to perform its very
special function. At just the right time, that is, when
the time to pass from childhood to adolescence has come,
an alarm clock goes off in the hypothalamus. This indicates
that the hypothalamus must begin a new job.
Actually, scientists use the comparison to a clock
to describe this process in a more understandable way.
Of course, there is no clock in the hypothalamus, but
comparing it to a clock is the best way to describe
how cells wait for years to go into action at just the
How do the cells that make up the
hypothalamus know that the right time has come? The
scientific world has not yet been able to explain how
a small piece of flesh can act in such a conscious and
programmed way.10 It is likely
that the details of this system will be understood as
years go on, and when they are understood, they will
provide another proof of the perfection of God's creation.
With the sounding of the alarm, the hypothalamus secretes
the special GnRH hormone. This hormone sends a command
to the pituitary gland to secrete two hormones, the
Follicle Stimulating Hormone (FSH) and the Luteinizing
These two hormones have very special functions and
marvelous abilities. Each one begins the process of
physical differentiation and development of the male
and female body. The FSH and the LH hormones have been
designed to effect the areas in which this change will
occur and they act as if they knew very well what they
have to do.
Because of its "hidden" clock, the brain's
hypothalamus area "understands" when
a person's adolescence has started. And this clock
operates in every human being without breaking
down or stopping.
In the female body, the FSH hormone causes the maturation
and development of eggs in the ovaries and ensures the
secretion of the very important estrogen hormones by
The FSH hormone is secreted according to the same formula
in the male body, but here it has totally different
effects; it stimulates the cells in the testes and initiates
the production of sperm.
In the female body, the LH hormone ensures that the
maturating egg is released and that another hormone
called progesterone is secreted.
LH performs a different function in the male body.
It stimulates a special group of cells in the testes
called the leydig cells and ensures the secretion of
It is very interesting to think that these hormones
are produced according to the same formula in the bodies
of each of the sexes and that in each case the effects
are totally different. How do the hormones know the
difference between the male and the female body? How
does it happen that a hormone composed according to
one formula causes the production of testosterone in
the male and progesterone in the female? How can hormones
of the same formula recognize the male body on the one
hand, and ensure the development of the male voice and
musculature, and, on the other hand, how can they know
the chemistry and special qualities of the female body
and make the changes accordingly? Who placed this wonderful
genetic program in the cells according to which one
hormone has different effects and causes the development
of the different sexes?
Hormonal Control in Females:
LH secreted from the pituitary gland ensures that
the egg is released and that progesterone is secreted.
FSH ensures the formation and development of egg
cells in the ovaries.
Hormonal Control in Males:
LH secreted from the pituitary gland stimulates
a special group of cells in the testes (leydig
cells) and ensures the secretion of testosterone.
In men, FSH stimulates the testes cells and initiates
Who has the intelligence to formulate a plan such as
this? Do chance events have such intelligence? Do unconscious
cells have it? Or do the atoms that form the cells have
It is completely evident that this intelligence does
not belong to chance events, to the cell or to the atoms
which compose cells. These developments are regulated
with a view to the particularities of males and females
and show us the existence of a deliberate design and
plan. This plan and supreme intelligence belong to God.
