Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.
"THY "SEED" (SINGLE) ONLY ONE SPERM EXACT FOR WHAT THE SCIENCE SAY
“Every sperm is sacred. Every sperm is great. If a sperm is wasted, God gets quite irate,” goes the song from Monty Python’s movie The Meaning of Life. If the lyrics strike you as funny, it’s most likely because calling a sperm cell “sacred” sounds ridiculous when men can produce so many of them.
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
In contrast, women are born with an average two million egg follicles, the reproductive structures that give rise to eggs. By puberty, a majority of those follicles close up and only about 450 will ever release mature eggs for fertilization.
But if it only takes one sperm and one egg to meet and create a baby, then why do men produce such a whopping number of sperm? Wouldn’t it be less wasteful for a man to release a single sperm, or at least fewer, to meet one egg? This single sperm is the choosen one.(Jer.1:5)
In Greek the Word use in Luke 2:21 "of Concieve " is "Sullambano" with means:
sullambano sool-lam-ban'-o: to clasp, i.e. seize (arrest, capture)To attract and hold: (Sperm cell and Egg cell attract each other ,and hold each other in pre-conception attraction complex (PCAC).
For we are resident foreigners and nomads in your presence,(1 CRONICLES 29:15) "Nomads in your presence for long journey.
"In humans fertilization takes place in the ovarian (fallopian) tube. Under normal conditions the egg cell arrives in the first (proximal) part of the tube directly from the ovary In the mean time the sperm cells have completed a long journey up to there. They have been deposited in the female vagina and have swum all the way from the vagina via the uterus to the ovarian tube. Many millions of them (more than ninety percent of the number that were present in the male ejaculate) have passed away or have become out of order by all kinds of biological barriers that crossed their way (e.g. the sperm hostile properties of the cervical mucus). Anyhow there exists a reasonable chance for both gametes to meet each other.
... At the end some tens or hundreds of sperm cells will actually reach the egg cell and organize themselves in a circular or radial orientation with their heads directed towards and concentrating on the egg cell.
Did not he that made me in the womb make him? And did not one fashion us in the womb?.(Job 31:15)
At this moment so-called nutritive cells, the corona radiata, still surround the egg cell. From the evidence of the in vitro fertilization procedure it is known that in the next phase a so-called pre-conception attraction complex (PCAC) is generated for several hours (see figure). Under the influence of the substances secreted by the egg cells and the nutritive cells, the sperm cells now undergo important changes. For example they lose their so-called acrosome (outside shell). Without this happening a sperm cell is not capable of fertilization at all. On the other hand the presence of sperm cells and related substances obviously evokes chemical reactions in the egg cell and her coat (zona pellucida), making her more receptive for the eventual fusion process between the two cells. So it is obvious that the mere existence of this biological attraction complex is a necessary condition for the actual process of conception. Both cells seem to exchange and settle mutually within the chemical and biological conditions for the eventual decision whether or not a sperm cell will enter (fuse), and if so, where, which one and when. In a very subtle mutual process of encounter and exchange of signals and substances both cells are prepared for the actual process of fertilization and conception.
The reason for this predicament boils down to two words: sperm competition. Since the dawn of the sexes, males have vied with each other to get as many of their own sperm near a fertile egg as possible. Getting more of your sperm closer to an egg means there is a greater probability that it will be you and not your neighbor fertilizing it.
This kind of competition is an evolutionary imperative for males of any species. If a rival’s sperm fertilizes an egg, then an opportunity to pass on your genes is lost. Through many generations, as the reproductive spoils continually go to the highest sperm producers, their genes are passed on. The genes of the smaller sperm producers are eventually weeded out of the population and become a footnote to evolutionary history.
But if it was just a matter of ‘more is better,’ then animals of all species would have evolved ridiculously large testicles in a bid to overwhelm the competition. But it’s not quite that simple—numbers are important, but so is proximity. Fertilizing an egg is not just about how much sperm you can produce. It is also about how close you get your sperm to it.
In the early 1980s, researchers in the United Kingdom and the United States realized that both proximity and number were important factors in the physiology of primates, including humans. In primate societies with rigid social structures and one dominant male who mates with all the females, testes trend towards the small. In gorillas, for example, they are very small relative to body weight. (Don’t tell them that.) In gorilla society, one male defends a harem of females to ensure only his sperm gets anywhere near their eggs. In this case, making a lot of sperm doesn’t really help the male gorilla get the job done.
For chimpanzees, on the other hand, sperm competition is a serious issue. In chimpanzee society, many males and females live together in large troops, and females have sex with many males in a short span of time. This is why male chimpanzees possess the largest testes of all the great apes, weighing in roughly 15 times larger than gorillas, relative to their body weight. This gives them a better shot at swamping out the competition.
Human males fall somewhere in between gorillas and chimps. The average man’s testes are roughly two and a half times as big as a gorilla’s but six times smaller than a chimp’s, relative to body weight. This has led some researchers to question whether sperm competition was ever at work in human societies, or whether our relatively large testes are just a hold over from an earlier period in our evolutionary history.
