the miracle of the hormones

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 right time.

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 Hormone (LH).

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 this area.

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 testosterone.

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 sperm production.

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?

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.
