What a Young Husband Ought to Know Part 10

CHAPTER XIV.

THE CHANGES WHICH PRECEDE, ATTEND AND FOLLOW CONCEPTION AND CHILDBIRTH.

From the moment of conception, during the months of gestation, at the time of childbirth and after, changes of great interest take place in the germ of human life and in the body of the mother. Her body is marvelously fitted for the reception and development of the ovum, the embryo and the fetus through the various stages of fertilization, germination, development, maturity, to the time of the eventual exit of the child into the outer world to begin its own independent life.

Something of the adaptation of the body of the mother to its marvelous purpose may the better appear if we think of some of the greatest mechanical achievements of man.

A watch is one of the best products of human ingenuity. It has taken nearly six thousand years to produce it. It is a wonderful piece of mechanism, yet it is, after all, not a complex product like the human body. If a watch could be constructed that could oil and renew its own parts, so as not to stop or break, or need repairing or oiling or cleaning, such a product would be more complex. But if, in addition to running on uninterruptedly for a long series of years, or almost an entire century, suppose it could be so constructed and const.i.tuted that, without interrupting the orderly movement of its works or its accuracy and correctness, it should, at intervals, produce other watches like itself. Truly such a watch would be a marvelous complexity. Yet just such a complexity is found in all the forms of vegetable and animal life about us. Interesting as is the study of life at any stage, it is specially interesting and impressive during the periods which preface, accomplish and follow the wonderful period of gestation; and it is specially important that the individual who stands so closely related to this profound and awe-inspiring mystery as does a young husband should have such knowledge of what this condition has to teach as comes within the realm of human understanding--both because of its importance to his own happiness, the happiness, safety and well-being of the mother and her offspring, and because such knowledge will tend to purify the mind of those gross and debasing thoughts which too frequently cl.u.s.ter about the most important and most sacred relations of married life and the endearments of home.

Something of what these changes are which precede, attend and follow reproduction in the human family may be beautifully seen in a conservatory or garden, or even learned from the frail flower that blooms by the roadside.

When, in the springtime or summer days, the plant has reached its maturity, as instinctively as if it foresaw in the coming days of autumn and in the ice and snow of winter the possibility not only of death but of total extinction, its entire nature centres in one grand struggle to escape pending extermination and live, if not in its own body, yet in the life and beauty that shall be reproduced in the plants that are already begotten in the longing for the perpetuity of its own life. The dual parent-nature is quickened. Forgetting the present, and longing for a place and a part when the warm and quickening breath of spring shall again usher in a new day of life and beauty upon the earth the plant henceforth lives, not for the present, but for the future; not for itself, but for those that are to be. The buds begin to form. The plant has learned the purpose of being and throbs with the mystery of life. In the thought of death it has learned to live. In fear of extinction it has learned to perpetuate and multiply itself a hundredfold. The flower unfolds. The dual parent-nature of the plant lives with intensity in their common effort. The flower is in a pa.s.sion of beauty, in an agony of splendor, perfuming the nuptial hour with a sweetness that distills upon the air, arresting the hurrying steps of all who pa.s.s by. Who shall dare to interrupt that ceremonial, whose ruthless hand shall dare defeat that high and holy purpose? The fragrance invites the bees and insects to the nuptial feast. For them there is pollen and nectar in abundance.

They bear gifts of quickening pollen from other plants, or swing the anther censers that waited the coming of expected guests. The corolla of beauty screens the enchanted partic.i.p.ants. The ceremonial is over, the hour is ended. The ovules have felt the thrill of life, the beauty fades, the fragrance is gone, the wedding-garments are laid aside, and henceforth the father-nature and the mother-nature of the plant live not for themselves, but for the life they have begotten, and the plants that shall be. Their joy abides, and they live in the glad hope of partic.i.p.ation, in the succeeding resurrection of the life and beauty and fragrance that is to await the coming of another springtime.

What we have written in allegory takes place in fact. Every intelligent observer has noted the depth of color, pa.s.sionate beauty, and sweet fragrance of the flower as the hour approaches when the stigma awaits the pollen which is to fertilize the ovules that lie hidden away in the ovary or pod. When that union has been effected the flower fades, its petals fall off; the calyx, which as a vase held the corolla erect in its splendor, but which remains to s.h.i.+eld and protect the ovules or little seeds which are being formed and perfected, now droops, turning toward the earth. Is this a sign of sadness, or that there is no longer any joy in life? No, no, not at all. It is the evidence of its fidelity to the sacred trust that has been committed to it. It has found a new joy, a more abiding happiness. Then it held up the corolla that the sun and the angels might look in upon the happy and holy beginnings of life, while now, in the protection of its sacred trust, it turns down, that it may shed the rain and everything that might intrude or hurt the tender plant that is so mysteriously encased in that pod that enlarges with the growing life that is within it.

What is true in the reproductive life of plants is also true in the reproductive life of man. The changes that take place at the moment of conception and during the period of gestation are full of marvelous beauty and profound mystery. The bright eyes, the ruby lips, the ruddy glow on the cheeks, the comely attire, the attractive manner, the persuasive sweetness, the subtle but indescribable attractiveness, are manifestations in human life of what may be seen and studied with such impressiveness in the reproductive life of the flower. The changes which follow may not be as immediate; and while, to the unknowing and un.o.bservant, they may not at first be totally un.o.bserved, yet to the devout student they are quite as manifest and p.r.o.nounced as in the flowers; and the study of these changes which attend the beginning, the growth and the completion of reproduction is one of great interest to every intelligent person, although its clear presentation to those who have no knowledge whatever of the subject is attended with some difficulty.

As the birds at the mating season put on their most gorgeous plumage, sing their sweetest songs, and in the building of their nests work in sweetest accord, so it is also in human life. When the nest is completed, the eggs laid, and the incubation or hatching begins, the plumage soon loses some of its l.u.s.tre, the songs become less frequent, and the parent birds prepare for the feeding and care of the bird-life that is soon to fill the nest.

But all this quickening of life and growth that takes place in the egg within the nest under the warm body of the mother-bird, in the human mother takes place within the nest or cradle which G.o.d has prepared within her body. Her young is of a higher order. The protection and preservation of the unfolding human life is more important, and hence the greater care displayed in guarding and nouris.h.i.+ng it.

The future mother, whose nature only recently craved her husband's caresses and embraces, now, perhaps all unconsciously to herself, changes, to fit her for the better completion of the sacred and holy work which G.o.d has a.s.signed her. The eye loses somewhat of its l.u.s.tre, the cheek its ruddy glow, and her entire being something of that pervasive sweetness which but recently made her peculiarly attractive.

But to the intelligent husband and true father she is none the less, but rather the more, an object of love and adoration; and if she is intelligent, and understands the high and holy nature of that which is being wrought within her own body, and the exalted honor which G.o.d has bestowed upon her in making her a co-creator with himself, she will not manifest the belligerent and uncompanionable spirit which too often characterizes the bearing of some women during this period of unfolding life.

While it is true that the changes which accompany this period are more marked in woman than in man, yet when we remember that a close study of the reproductive nature of man in married life discloses a responsiveness to her condition and desires, it will readily be understood that during the period of his wife's gestation his nature is measurably moderated by her condition, for in health the reproductive nature of man is responsive to the promptings of his wife. The poet wisely says:

"As unto the bow the cord is, So unto the man is woman.

Though she bends him, she obeys him; Though she draws him, yet she follows-- Useless each without the other."

Where existing facts in any particular case are discordant with this poetic figure the causes can usually be found in an abnormal pa.s.sion in the man, or a measurable absence of s.e.xual inclination in the woman, frequently caused by ruinous modes of life and dress. While human beings are generally very different in this respect from the lower animals, yet something of what these changes are may be suggested by noting the changes which take place in bird life. As the wave of life rises to its crest in the male nature, every department of his being is aroused to greatest activity and perfection. His plumage becomes l.u.s.trous, he sings with sweetest note. In some of the animals the intensity of his vitality bursts out in a growth of great antlers; but when the mating season is pa.s.sed the plumage fades; the antlers drop off as the receding tide of life sets in. These marked changes among the animals are by no means paralleled in man; yet there are semblances or faint shadows of them in the modifying of the male nature.

While such external and manifest changes as we have indicated are taking place, marvelous things are being wrought within the mother's body. The ovum or egg (for that is what it truly is), after it has left the place where it matured in the ovary, is impregnated by the spermatozoon, which, in its restless search for the ovum, presses forward from the place where it was liberated in the v.a.g.i.n.a, up through the womb, and out through the Fallopian tube toward the ovary; or the ovum may pa.s.s through the Fallopian tube and into the womb, to await for a brief period or a few days the coming of the sperm or spermatozoon, without which it must remain incomplete and perish.

G.o.d might just as easily have ordained that the ovum should be complete in itself, and that, without any intervention or co-operation, at appointed intervals the mother should bring forth her offspring. But there were reasons why this should not be. The begetting and bringing forth of human life involves issues too vast to be committed to a single individual. Without a defender or protector during this period when the mother is rendered measurably helpless by her condition, would imperil the safety and even the life of both parent and child. Two must share the risks and the responsibilities. The father, during this period and that which follows, is to bear the burdens of life largely alone. He is to provide food and shelter. He is to be the guardian and the defender of his more dependent companion. Should exposure or peril result in the death of the mother, the child must not be left without a natural guardian and caretaker. This young life is too precious to be exposed to possible peril. Its care, its nurture, its education is too important even to be risked with a single parent. The mother might "forget her sucking child, that she should not have compa.s.sion on the son of her womb," and it was important that the child should then have another, who is bound by natural and moral obligations, and by bonds of personal interest and tenderest affection, to care for it. This double parentage gives the child four grandparents instead of two, and eight great-grandparents instead of four. In this wise way the child is knit to many in an obligation to nurture and care for it, should necessity arise. If physical, mental and moral infirmity should exist in the mother, the force of such infirmity must be reasonably broken by a new stream of influences which tend to liberate the child from any inheritance of incapacity. If the father is wicked or worthless, the child is to find its defender and caretaker in its mother; or, should the mother possess these bad qualities, the child may find in its father its defense and help. The life and well-being of the child is so important that it must have two chances to be well-born and well-reared.

But this relation of interdependence is not only for the well-being of the offspring, but for the highest physical, intellectual and moral development and well-being of both parents. Parenthood comes not only to the mother, molding, fas.h.i.+oning and perfecting her in every department of her being, but when intelligently and reverently a.s.sumed, when discharged with fidelity and self-denial, it has its priceless endowments for the father as well. In view of the Creator's full and sacred purpose, who shall dare invade, or even lightly a.s.sume, the far-reaching responsibilities which G.o.d has united to parenthood? "What G.o.d hath joined together, let not man put asunder."

What intelligent man or woman shall dare trample under their feet all the sacred relations of life, and call into being an immortal spirit whose temporal and eternal destinies are to be affected by its advent into a world that is waiting to brand it because begotten of an illicit union? What husband or wife can regard with dishonor, or dare debase, the G.o.d-given powers of reproduction?

But to return to the subject of the changes which take place within the body of the mother during this period of wondrous interest. When the spermatozoa have been liberated in the upper portion of the v.a.g.i.n.a at the cervix, or small opening which forms what is called the neck of the womb, although such minute microscopic objects that when laid end to end it would require five hundred of them to make an inch in length, yet, with that wonderful activity of which we have written in a previous chapter, they immediately seek the doorway into the womb, that mysterious chamber where the ovum may naturally be expected to await their coming. We correctly think of persons, and not of things, as possessed of intelligence and acting in accordance with reason, but this mysterious natal chamber within the mother's body appears instinct with intelligence. It seems almost as though across its portals were written, in a language which every object and every spermatozoon might read, the prohibition: "None save those who bear the gift of life may enter or tarry within these portals." The ovum may remain for a period, and the spermatozoa that seek the ovum may enter, but neither may tarry unless each yields itself to the other in that mysterious union which results in life. Apart or alone, after a brief period, they must alike be cast out; no idler may tarry there; but that semblance to innate intelligence which rejects or casts out any incomplete part as a foreign substance accords a hearty welcome to the ovum that has been quickened into a new life by the entrance of a spermatozoon. No mother ever embraced her newborn child more lovingly, or regarded it with greater tenderness, than the womb receives the quickened ovum. When the ovum is quickened, every fibre of being thrills with a new purpose. A royal place is speedily prepared for the safety, nurture and development of the ovum.

The entire nature of the mother now centres upon the accomplishment of a special work--that of developing and bringing forth the new life begotten within. Great changes are to be wrought not only in the ovum, but the enlarging life and new necessities are to be met by corresponding changes in the womb itself. Not only is the minute speck of life which is laid within this human cradle to develop into a fully-organized human being, but the cradle is to enlarge with the growth of its occupant, and respond to the varying needs of the unfolding and developing body within.

It will require the aid of a microscope to discover and observe the object of our search and study. The egg of the bird bears some proportion to the size of its producer, for in them is stored up the nourishment which is to maintain the unfolding life that can be fed in no other way until it has reached an advanced stage of maturity, and has broken its sh.e.l.l and emerged into the outer world. The human egg is so small that it would require two hundred and forty of them laid side by side to make one inch in length. They contain the nourishment which is to foster this minute beginning of human life for a brief period, after which it is to derive all its nourishment from the mother. Her food is to furnish the material for its upbuilding. Its blood is to flow from her heart. The egg of the bird is encased in a porous covering through which pure air, with its transforming power, is to find its way to the developing life within; but this human egg and the life which it is designed to unfold must owe all to its mother. Her lungs must impart the oxygen it needs, and her body must minister to every function of the body of the child, until after a period of months, when it shall have reached that stage of development when it is prepared to enter upon its own independent life in the outer world.

This minute germ of human life, this egg so small that a thousand could be laid upon a ten-cent piece, this atom, which under the microscope shows a speck of oil and alb.u.min, which in the course of a few brief months is to const.i.tute a complex human organism, with all the perfected parts and wonderful adjustment of a human body, already contains the elements of a new human soul. Embodied in this undeveloped human germ is the future man or woman. Here are all the elements which are to make the successful mechanic, the farmer, the orator, or the statesman. Ingrained in these forming tissues may be scrofula, consumption or insanity. Here, already, are the inheritances which are to determine whether this being shall be temperate or intemperate, chaste or licentious. The moral nature has already received that bent which will incline it to reach out after G.o.d and heaven and holy things, or which will incline it downward to all that is base, destructive, and that tends to death. The history of this immortal being is already measurably outlined in the past life of the father and the mother. What they have been in their thought, in their character, in their being, that their child is largely to become.

This outline is now subjected to modifications by the thought and life of the mother during the few months while the body of her child is being unfolded, fas.h.i.+oned and developed beneath and so close to her own heart.

During these months, her life is to tell both upon the body and the soul of her child.

During the brief period while the germ within the fertilized egg is being nourished by the vitellus or yolk of the egg, great changes are taking place in the soft and delicate linings which surround it within the womb. While, of course, the greatest changes which take place during the period of gestation are chiefly within the ovum or egg, yet those which take place in the body of the mother herself are more manifest, and scarcely less marvelous. The mucous membrane within the walls of this enclosure begins to thicken; the small vessels which compose the structure of the inner surface begin to multiply, enlarge, and lengthen, until they are manifest to the unaided eye. This soft, velvety lining becomes thick and rich, but loses none of its softness and delicacy.

Every preparation is speedily made, and the fertilized egg finds lodgment in the thin, delicate folds of the membrane in the upper central portion or dome of the womb. The folds begin to grow about the egg, partially enclosing it, and shutting it off from the general cavity of the womb. At last the borders of this growing envelope meet, and form a complete and distinct enclosure. This thin, transparent tissue, which const.i.tutes a living envelope or sac, shuts off the egg or growing embryo from the rest of the cavity of the womb, which its increasing proportions are soon completely to fill.

The original membranous lining which covers the entire interior of the womb, and which has now become thickened or tumefied, as medical men say, is technically called the decidua vera, while that portion of the membrane which forms the sac that surrounds and encloses the egg is called the decidua reflex. These are known as "decidua," which means "not permanent"--a word applied to those things in nature which after a period drop away, as leaves, teeth and horns, which are shed or fall off. So the decidua reflex is to pa.s.s away with the birth, and the decidua vera is to change back again into its normal condition.

The egg, which during this period has considerably enlarged, begins to throw out upon all sides threadlike tissues, by which this germ of life becomes attached to and grows into the mother-life upon which it is engrafted.

It is through these filaments that the fluids which are to nourish and develop this unfolding life are imparted from the mother and received by the embryo.

As the attachment between the sac which encloses the egg more firmly and securely adheres to the walls of the womb the filaments which had formed upon all sides of the enclosing sac begin to disappear, except upon the side in contact with the womb. Upon that side they become more p.r.o.nounced, and in the third month the permanent attachment known as the placenta, through which the embryo is to receive its increasing supply of nourishment from the body of the mother, begins to be formed. The placenta is circular in shape, from one to two inches in thickness in its thickest part, and about six or eight inches in diameter. It forms the temporary medium of communication between the life of the mother and that of the child, and, properly speaking, is not a part of either. It is formed for a temporary use, which terminates with the birth of the child; and at that time the placenta, the umbilical or navel cord, and the membrane we have named, const.i.tute what is called the afterbirth.

The placenta is a flat, soft disk which is attached to the walls of the womb connecting the embryo by the navel cord, through which it respires or breathes, and receives nourishment, and discharges the worn-out particles of matter. It is through this attachment or cord that an intimate connection is established between the growing life of the ovum and the currents of life which flow in the mother's body. Through this placentic cord the embryo receives oxygen and all the elements necessary for its growth, upon the one hand, while, upon the other, it also transfers to the body of the mother the carbonic acid gas and other impurities which in the process of life are necessary to be thrown off.

CHAPTER XV.

THE CHANGES WHICH PRECEDE, ATTEND AND FOLLOW CONCEPTION AND CHILDBIRTH.

_Continued._

But while these changes have been taking place within the womb itself, and the decidua or thickened membrane has been forming about this developing germ of life, let us consider some of the changes which have taken place within the ovum itself. If observant when opening a hen's egg, the observer will notice that the yolk is covered by a very thin membrane which encloses and separates it from the other portion of the egg, and holds it in its rounded form. The membrane is exceedingly delicate, but sufficiently thick and strong to serve its intended purpose. Now, the human ovum or egg consists of a vitellus or yolk, which is covered by a similar membrane, known as the vitelline. When this ovum or egg has been fertilized or impregnated, remarkable changes take place. This vitellus or yolk undergoes a series of segmentation or dividings which are known as spontaneous segmentation. The single minute yolk divides itself into two smaller b.a.l.l.s or segments. These again subdivide into four; these four subdivide into eight, the eight into sixteen, and so on, resulting in the rearrangement of the yolk into a finely divided granular ma.s.s. While this division is in process, the divided parts arrange themselves orderly about the inner surface of the vitelline or yolk membrane, with the minute microscopic s.p.a.ces between filled with a transparent fluid. While these cells have been multiplying and become so abundant as to be flattened against the internal surface of the yolk membrane, they have developed into true animal cells. The edges of these cells, where they come in contact with each other, form a continuous organized membrane, which lies just within the yolk membrane.

This membrane is called the blastodermic membrane.

This new membrane, formed within the sac which originally enclosed the yolk of the ovum, now divides or separates itself into two distinct layers, known as the outer and inner blastodermic membranes, also called epiblast and hypoblast. The egg at this stage of development presents the appearance of a small round sac, the walls of which consist of three layers, each succeeding layer lying immediately within and in contact with the other which encloses it. The outer one of the three is the primitive yolk sac, the second is the outer layer of the blastodermic membrane, and the third the inner layer, while the interior cavity of the egg is filled by the transparent fluid previously mentioned.

In order to understand the beginnings of life it is important to have a clear conception of these different sacs, for these two membranes lying within the yolk sac, and together known as the blastodermic membrane, and separately as the outer and inner layers of the blastodermic membrane, contain the anatomical elements from which the organized being with its fully-formed body is to grow. Indeed, it may be said that these two blastodermic membranes are the body of the embryo which is to develop into the fully-formed physical man.

The noting of this division into two separate layers is important, for the outer one develops into the skin, spinal cord, muscles and bone, while from the inner layer is formed the intestinal ca.n.a.l and the organs of vegetative life.

Between these two blastodermic membranes other minute tissues are formed, the office and end of which are not so fully understood, and the consideration of which would lead us into intricacies beyond our present purpose.

The first visible sign of the organic structure of the human form is discovered as it takes shape upon the exterior wall of the blastodermic membrane, known as the embryonic spot, and known also as the primitive trace or furrow. It is supposed that from this is formed the spinal ca.n.a.l, with the dorsal plate upon either side, from which springs the framework of the bony structure, and at one end of which is the large rounded cavity which forms the receptacle for the brain and the medulla oblongata, or the upper cranial portion of the spinal cord, which is to control respiration, and at the other extremity of which, in a later stage, will sprout or grow the legs and feet.

Without complicating the subject too much for the clear understanding of the ordinary reader by undertaking to explain minute changes which are very interesting to specialists, but likely to detract from its interest and value to the ordinary reader, let it suffice to say that in the course of a brief period the embryo which has grown mainly from the two blastodermic membranes which we have described, and is attached to the walls of the womb by the placenta and cord which carries the blood and life-currents from the body of the mother to the growing body of the child within, is at this period of its development surrounded and enclosed by a number of membranes. The outer one of these is the inner lining of the womb itself, known as the decidua vera. Within this is the decidua reflex, the membrane of the womb, which extended itself and grew around the ovum, completely enclosing it. The third is the chorion, forming the outer membrane which encloses the fetus, and within which is the amnion, or innermost membrane which surrounds the fetus, and between which is another membrane, called the allantois.

The amnion, which is the innermost of the membranes surrounding the fetus, seemingly has a special office, which is to secrete the fluid technically called the amniotic. This fluid is popularly known as "the waters." This secretion performs several important offices. It protects the fetus from any local pressure or blow, and so distributes any pressure as to enable all the parts to grow without danger of distortion and deformity. It also affords the fetus greater freedom of motion, and protects the womb and other parts from injuries which might otherwise be inflicted by the fetus after quickening. Within this fluid the fetus floats during its formative period, and when the time of birth comes the breaking of the sac which contains this fluid enables it to flow out, lubricating the parts, or channel, through which the newly formed being is to pa.s.s in its exit into the outer world. The importance of this fluid in this latter office is of great moment. When the sac breaks and the waters flow away too much in advance of the birth of the child, there generally occur the inconveniences that attend what is called a "dry birth."

As already mentioned in a previous paragraph, during the first weeks of growth the embryo is nourished the same as the young chick within the egg, by the yolk, in which its earliest nourishment has been stored.

Soon the delicate union is formed between the chorion by the gathering and multiplication of the villi or minute hair-like membranes, which gather into a compact ma.s.s and adhere to the adjacent portion of the womb. This formation is known as the placenta, previously described, which is const.i.tuted of two portions--the maternal side, which is toward the walls of the womb, and the fetal side, which is toward the growing fetus. Upon the inner side, the placenta is united with the fetus by two arteries which are wrapped around the one vein, which together unite with the body of the placenta. Through these the life-currents flow; and, while the circulation between the bodies of mother and child are not direct or uninterrupted, for the fetus has its own measurably independent circulation, yet from the time the connection is formed until the cord is severed at birth the fetus derives all its nourishment from the mother.

Let us turn now to note the rapid changes which take place within the germ or egg from the time of its impregnation to the hour of the birth of the child. The changes, although seemingly very minute at first, are nevertheless very rapid from the beginning to the period of maturity and birth. The following account, taken from "Plain Talks on Avoided Subjects," by Henry N. Guernsey, M.D., const.i.tutes a goodly portion of the introductory chapter of that excellent little book, and presents the matter in the intelligible and impressive manner we desire for this place, and is quoted in full by permission:
