With the number of children born every day on planet Earth, it is easy to miss the complexities of human reproduction. All animal life on our planet radiates this complexity, and the sperm cell is the most complex of all the cells in the body. Science is still struggling to understand sperm cell design, but we are learning more about how it functions as technology opens doors that were previously unavailable.

The sperm cell has three parts: (1) The head, which contains a haploid nucleus carrying half the normal number of chromosomes. It also has an acrosome, which contains enzymes that enable it to penetrate the egg. (2) The middle, which is packed with mitochondria to provide energy for the sperm’s movement. (3) The tail (Flagellum), which allows the sperm to swim through the female reproductive system.

Sperm cells are also biconcave or disk-shaped, allowing them to absorb oxygen more quickly and rounded to flow easily through the tiny capillaries. Sperm cells can swim fast thanks to a tail, a streamlined shape, and a high concentration of energy-transferring mitochondria.

The sperm cell design is just half the story. The egg becomes concave at one spot, allowing a single sperm cell to complete fertilization. All animal life depends on this design. The mechanism by which this happens is not understood and is the subject of modern research. We take for granted the fact that animal life can reproduce, but the design that makes it possible speaks eloquently about the existence of God.

Why Two Genders?
The simplest one-cell life forms can reproduce by dividing, but advanced life requires both a male and a female to procreate. We wonder why two genders are needed. How can naturalistic evolution explain sexual reproduction?

Science has discovered that sexual reproduction is much more complicated than we ever would have expected. Various plants and animals use different processes involving two genders to reproduce. The processes involved vary dramaticly between species. Would it not have been simpler for evolution to result in creatures with the ability to conceive a new life within themselves and give birth to that life without the need for another of the same species?

Think of how much more complicated the evolution of a new species would be if two genders had to evolve at the same time. If a male of a new species evolved with no female, that new species would become extinct when the male died. You must have two genders of the new species at the same moment in time with the same genes and the corresponding reproductive organs. Otherwise, reproduction would not be possible.

Genesis 1:27 says, “So God created mankind in his own image, in the image of God he created them; male and female he created them.” God created humans in His image spiritually, but He gave them a physical morphology complimentary to each other. He made the man first and then showed him all of the animals. (Genesis 2:19, 20). Surely Adam noticed that there were males and females in the animal world. As a result, Adam would have realized that something was missing from his life. He needed someone like himself, but different.

After the sex education lesson, God took some of Adam’s physical body to create his complimentary half. Adam’s reaction, “(At long last) this is now bone of my bone and flesh of my flesh.” This was God’s design for love and reproduction. Why two genders? God intended for us to have two genders to complete each other. It didn’t happen by accident. It couldn’t have.

F. LaGard Smith has written an excellent book which goes into great detail on this topic. The title is Darwin’s Secret Sex Problem and we highly recommend it.
