But there are also other differences less manifest to the superficial observer, but none the less real and important to those who would comprehend the wonderful wisdom of the Creator and intelligently prepare themselves to receive the good which is designed for and is possible to intelligent men and women.
There are inherent differences of character and modifications of temperament which can be best understood by studying the very earliest manifestations of human life when we examine the sperm of the male and the ovum of the female as seen under the microscope. These characteristics are not imaginary, but inherent, and are manifestly designed and intended by the all-wise Creator. And it is only when we study these characteristics in their entirety, with a desire to understand the divine purpose, that we can measurably comprehend how these individual differences in each contribute to the blessing and the well-being of both.
The part contributed by the mother in the reproductive act toward the life of the future child is called an ovum, which means an egg; for all forms of life, both vegetable and animal, begin with a seed or egg, which are two names for the same thing. In the lower forms of life these eggs are usually produced on the exterior of the plant, while in the higher forms of life, as, for instance, in the bird, the seed or egg is produced in the inside of the body, and after being perfected is expelled, to be hatched in a nest, where the young, when they attain their proper size, break the shell and emerge into the outer world. In the highest forms of life the ovum reaches its maturity in a department of the mother's body which is called the ovary. In woman, at the end of a period of twenty-eight days, as a succeeding ovum ripens it passes into a tube which awaits its reception, and is moved onward into the womb, where it remains for a period, awaiting the reception of the male element called the spermatozoa. This is the plural, while a single one is called a spermatozoön. The ovum or egg of the mother is so small that two hundred and forty of them would need to be laid side by side in order to make a row one inch long. The spermatozoön, the principle of life contributed by the male, is so small that it is not visible to the eye except by the aid of a microscope, and, when seen, somewhat resembles a pollywog. These minute centres of life are alive, and move in a fluid which is secreted by the male organs of reproduction, and which is generally called semen. Now, if we study the characteristics of the ovum and of the spermatozoön we may be surprised when we discover some of the same differences which characterize men and women from infancy to old age.
In passing through the tube which is to carry it into the womb from that portion of the body of the mother where it has attained its growth and perfection, the ovum is passive—does not move by its own inherent life, but is carried forward to its designed place by the movement in the tube itself, the same as the food which is masticated in the mouth is passed on to the stomach, not by any action in the food itself, but by the movement of the esophagus, which passes it onward to its destined place in the stomach. In other words, the ovum is passive.
When we come to the spermatozoa, or sperm, of the male, we find an entirely different manifestation. Just the same as you see the pollywog moving in the water, or tiny fish swimming about in the pool, so the spermatozoa move with activity and vigor in the semen, and when this has been transferred to the interior of the body of the mother in the manner in which God designed, it retains its activity, moving vigorously about in the upper portion of the vaginal cavity until it finds the entrance into the womb. Passing through and above the cervix, it continues to move about with great activity until it finds an ovum, which it seeks with avidity. When it reaches the womb, if there is no ovum present, it may remain there for a period of days awaiting its arrival, or may find its way into one of the Fallopian tubes which lead out to the ovary, and even go in quest of the object of its search as far as the ovary itself. These little creatures, one-fortieth of an inch in length, and requiring that hundreds of them should be laid side by side in order to extend one single inch, are so numerous that hundreds of them exist in a single drop of semen, and yet a single one is all that is necessary in order to fertilize the ovum and render complete the beginning of a new life.
While the ovum is passive, the sperm of the male is characterized by great activity and remarkable vitality. Dr. Napheys says: "The secretive fluid has been frozen and kept at a temperature of zero during four days, yet when it was thawed, these animalcules, as they are supposed to be, were as active as ever." In her interesting book, entitled "Life and Love," Margaret Warner Morley says: "Under the microscope these active forms have been seen eagerly moving around and around the egg until one, more fortunate than the rest, finds admission and dissolves into the substance of the egg—not to be finally lost, however, for, as we know, this inexplicable union results in the growth of a new creature like neither parent, and yet like both, each cell having given to the new life certain characteristics of the creature from which it was derived."
This greater activity of the sperm is seen also at the birth of the child; for physicians tell us that the pulse of a male child at birth beats two or three times a minute faster than that of a female child. The tissues of the male are also characterized by the same superior activity; and not only among men, but among all creatures. The tissues of the male have a greater tendency to change than those of the female. In the very fibre of her structure she is quiet, while he is more active.
Characterized by this more marked vitality, more sturdy form and more muscular frame, we would naturally expect that the vitality of male children would be greater than that of female children. But this is not the case. It is claimed by some good authorities that about five per cent. more male than female children are born into the world, but at five years of age more girls are alive than boys.
And what may seem increasingly strange, when we consider the greater perils to which the life of women is exposed in childbearing, the "expectation of life," as life-insurance companies designate it, is greater in woman than in man, and when the census of old persons is taken, the larger number of them are women.
The civil law recognizes this more passive nature of females and the more intense activity of males by regarding the man as the criminal in all actions for fornication or bastardy. While public sentiment ostracizes and is more severe and unrelenting with the woman, the law always inflicts its penalty upon the man.
