The phased process of conceiving a child: by day, as is the case

Opinion that fertilizes the egg the fastest sperm is fundamentally wrong. Victory will be won by one of them, which is faster than others will go through kaptsitatsii (chemical process occurring on the surface of the male germ cell, which contributes to its penetration into the egg). Capacitation leads to the dissolution of the outer membrane surrounding the egg cell. And this dear young lady, in her turn, also doesn’t sleep: with the help of her microvilli, the female sex cell seems to embrace the spermatozoon and literally draws it into itself. Immediately thereafter, for a short period of time (literally a few seconds), the egg cell forms electrical insulation that prevents the penetration of other spermatozoa. Subsequently, on the surface of an already fertilized egg, a protein “shell” is created impenetrable for losing zhivchiki, after which the nuclei of both cells — male and female — merge into one new life and conception occurs.

Embryo development in the uterus

From the moment of conception and the connection of the parent germ cells, the whole body of the future mom receives a signal of perfect fertilization. All organs and systems begin to work entirely and completely in order to preserve pregnancy. The level of immunity of a woman drops sharply, so that the fertilized egg is not rejected by the body as a foreign body. After the fusion of germ cells, the so-called zygote is formed. This tiny education, which concentrates all the information transmitted from the expectant parents to the baby — a half set of chromosomes determines what will be the gender, hair and eye color, etc. Being in the fallopian tube, the zygote only after seven days moves into the uterine cavity, where it is attached in the most “liked” place. During the first week after conception, all nutrition of the embryo occurs due to the corpus luteum (this is a temporary gland that produces the so-called pregnancy hormone - progesterone. This hormone after conception activates the growth of the endometrium and prevents the release of a new egg and the onset of menstruation) "the embryo is in the wall of the uterus, the expectant mom needs to start with great care to monitor their diet, as well as the emotional and physical condition. Indeed, now the development of her future baby depends on it. But it is unlikely at this stage a young woman admits the thought, what a miracle happened in her body. At the very least, she can begin to guess about the onset of pregnancy only a few weeks after fertilization of the egg cell and conception. Delay of menstruation, possible morning attacks of nausea, swelling of the mammary glands may well be the reason to quickly go to the pharmacy for pregnancy tests ...

Miracle begins

In another way it is quite difficult to call. Indeed, the true miracle that occurs most often at night, while parents are sound asleep. The process of conceiving a child begins with the discharge of seminal fluid into the woman's vagina. In a relatively small amount of nutrient solution, which also allows to lower the acidity of the vagina, there are about 3 million spermatozoa. Each of them carries the X or Y chromosome, and depending on which of them succeeds first in penetrating the egg cell, a boy or girl will be formed.

But we ran a little ahead. While the process of conceiving a child has not yet begun. It is just that the spermatozoa capable of fertilization has penetrated into the body. Now begins their long and difficult path to the goal. They can remain active for 9 days, and if during this time they are lucky enough to meet a mature egg on their way, their lives will not be in vain.

Fertilization

Since the process of conceiving a child is quite secretive, we can only learn about it from films or books. The woman herself is not given to feel the movement of the sperm and their fusion with the egg. Many people mistakenly believe that all the sacrament is performed in the womb. This is not true. Sperm through the vagina really fall into this large, muscular pouch. However, this is not the end of their journey. Then they have to go through the fallopian tubes, where the main prize, a ripe egg cell, can wait. About 24 hours, she retains the ability to fertilize, and, obeying the programmed program, moves to the uterus. If the spermatozoon does not meet and fertilize it on this way, the egg cell will reach its goal and collapse. Menstruation begins, after which the cycle will be repeated.

In the fallopian tubes

These are paired organs that connect the uterine cavity with the abdominal cavity. They are equipped with ciliated epithelium, the cilia of which are directed inwards. Of course, not just. They are necessary in order to push the egg to the uterus. It is here that the mature ovule is surrounded by sperm. Each of them seeks to penetrate her, but only one succeeds in it, in rare cases two, then there is a chance that twins will be born. It may also be such an option that two eggs will come out simultaneously. In this case, both of them can be fertilized, and the mother also takes out two babies, but they will not look like two drops of water.

It's amazing how fertilization happens. The sperm head penetrates into the egg cell, it contains a special enzyme that slightly dissolves the wall and makes it possible to merge. After that, the tail falls off. He fulfilled his motor function and is no longer needed. At this point, the surface of the egg changes. Now this is a zygote, and access to it to other sperm is closed.

The beginning of a long journey

Then you need to consider in more detail how the process of conceiving a child occurs by day. What is the overall picture now? The nuclei of the egg and sperm are combined into one. A zygote is formed. In about a day and a half, division begins. While still in the fallopian tube, it is already turning into a complex cell complex. And 48 hours after the merger, the zygote finishes the first stage of division. Now these are two cells called blastomeres. In size, they are still very large, but gradually the number increases, and the cells decrease. In this case, the zygote remains the same size. Fallopian tubes are not at all a suitable place for intensive growth.

Quick complication

Every pregnant woman becomes very interested in the process of conceiving a child by day. How does the birth of a new life take place at that moment when no one has yet understood about this miracle. So the third day. No, not yet pregnancy, it begins its countdown from the moment of implantation of the embryo in the uterus. It is still the third day of its formation. Now in the composition of the zygotes from six to eight blastomeres. At this time, the embryo already has its personal genome.

Day four, the zygote begins to move into the uterus.

All this time, not in vain. Now the zygote already consists of 16 cells, and their chaotic accumulation begins to take on a certain shape. In other words, the embryo is being compacted. Soon the zygote will leave forever the place where the formation of the future little man began. However, this period is marked by a certain danger. The fact is that if, for some reason, the fertilized egg cannot descend into the prepared womb, it can be implanted directly into the fallopian tube.

Since the process of conceiving a child takes place in the fallopian tube, nature provides for the modest size of the zygote, which it retains until it reaches the uterus, where there is room for growth and development. However, adhesions can lead to a narrowing of the tubes, and the egg just has no options for how to infiltrate the wall where it stopped. What happens next? It continues to divide and grows in size, leading to rupture of the fallopian tube. If you do not take emergency measures, the consequences can be very sad.

Fifth to seventh day

The phased process of conceiving a new life is always very interesting for the future mom. How amazing to follow the changes that are happening inside you with trepidation! But if we talk about this stage, the woman often does not even suspect her interesting position. And inside the uterus the embryo is already moving freely and is seeking shelter for the final implantation.

Having determined a suitable place, an egg is attached to the uterus. Now her long journey is over, there will be a cozy cottage for the next 38-40 weeks. By the way, at this stage the corpus luteum serves as a source of food for her, which means that the lifestyle of a woman has no influence on the development process.

The diameter of the embryo now does not exceed 0.5 mm. Literally in a few days, that is, on the 9-10th day of its existence, the zygote is completely immersed in the wall of the uterus. This period lasts about 40 hours and is called implantation.

Feeling of woman

If this is the first pregnancy, then most likely, you will write off all these symptoms for a simple indisposition. However, women who already have children react much more sensitively to the signals that the body sends. These days you may experience implant bleeding. At first glance, it looks like menstruation, with which he is often confused. However, the bleeding is not abundant, and most often passes on the first day. Sometimes brown discharge continues for 10-14 days, but this is already a signal to consult a doctor.

It is now beginning to produce hCG. Because of him, the woman feels nauseous in the morning, weakness and drowsiness. Almost everyone notes that the chest is poured, it becomes very sensitive. In addition, there is a tingling sensation in the uterus, a small heaviness in the lower abdomen.

We gradually considered the process of conceiving a child by day. The features of each organism may make some adjustments, but this is the general framework for the birth of a new life. And note that all this happens before you notice the first symptoms or notice a delay.

If pregnancy is very desirable

Some are waiting for the second strip on the test with fear, others - with hope and trembling. And how to speed up the process of conceiving a child, if you have been ready for motherhood for a long time, but it doesn’t work? It is very useful to track the onset of ovulation. Does this mean measuring the temperature every morning and drawing charts for months? In general, yes, but today there are special tests that show the onset of a favorable period for conception. The appearance of two strips indicates that ovulation has occurred. The egg cell is released from the ovaries and is ready to meet with the sperm.

A woman's body must be full of strength and energy, otherwise he simply will not take on such responsibility as carrying a baby. Therefore, it is very important to eat right, eat a lot of vegetables and fruits, greens, take vitamins. As for traditional medicine, it also offers a number of ways. For example: linden flower tea improves ovarian function, carrot seed infusion is useful for men, as it improves sperm quality. Infusion of uterine boron relieves inflammation and improves the menstrual cycle. Additionally, after sexual contact it is recommended to lie down for 10-20 minutes with legs raised up. This will allow sperm to get into the uterus faster. And, of course, think about your baby, because thoughts are material.

After intercourse

Mother Nature is a wonderful and wise creator. Everything related to procreation, she thought out to the smallest detail. Approximately in the middle of the menstrual cycle from the ovary there appears a “dam girl” - an egg ready for fertilization. She will remain in a state of readiness from 12 to 36 hours. If during this time conception does not occur after PA (sexual intercourse), the egg cell dies and is eliminated from the body along with menstrual bleeding. Thus, conception by days after ovulation can occur in a period from one to three days. In some cases, during the ovulation period, not one but several eggs are formed. In this case, there is a high probability of multiple pregnancy.

It is no secret how the fertilization of the egg. The female cell alone is not enough for the birth of a new life. The immediate process of conception begins when potential “suitors” - spermatozoa — rush into the female organism rapidly. As the heroes of fairy tales and epics, they have a long and dangerous path to the cherished goal. At the same time, the road is far from close - from the cervix to the fallopian tube - approximately 20 cm. Considering the tiny size of the spermatozoon, this is a very decent distance.

First test

The first thing "tadpoles" are in the vagina. This occurs in the first seconds after the act of intimacy. Here the first danger lurks them. Because of the acidic environment of the vagina, weak spermatozoa (and most of them) die within 2 hours, and never reach the cervix. So, out of 500 million spermatozoa that have fallen into the vagina after sex, only one third of it reaches the cervix. This is how natural selection works.

Second test

For successful conception in the uterus must be at least 10 million sperm. Reach the goal can not all, because the second barrier - the cervix, no less difficult and dangerous. An environment of high acidity also prevails here, and besides there is a mucus plug in the neck, preventing further movement. However, during ovulation the amount of mucus decreases slightly. The mucus usually moves in the direction of the sperm, as if "washing off" weak and indecisive in its path. The remaining specimens have sufficient strength to move "against the flow."

Third test

Passing the neck, the sperm are in the uterus. The reproductive organ in every possible way helps the "tadpoles", increasing the speed of their movement. Gradually, they beg to the last point - the fallopian tube. The catch of this test is that the tube is covered with epithelial cilia. Vibrating, they block the way to the ultimate goal for most applicants. So from the multimillion army of sperm cells trapped in the womb, by the end of the fallopian tube only a few thousand fighters remain in the row.

During its movement through the uterus and tubes, the sperm cells change qualitatively, becoming capable of fertilization. Gentlemen are more patient: if the egg is “late”, they will wait for it, and fertilization can be delayed for a period of 3-5 days.

Day One: Fertilization

And now the coveted egg is in the field of view of applicants. They surround her in attempts to complete the task.

But a reliable barrier stands in their way - the protective membrane of the egg. To pierce it, the sperm will have to try very hard. But nature once again came to the aid of "tadpoles" by putting an acrosome in their heads. This is a special substance that helps the sperm to dissolve the shell of the egg and penetrate inside.

Trying to penetrate through the barrier, most of the “fighters” die, depleting their vitality. But the protective layer is weakened in some places by the action of the acrosome. At this moment, that single sperm cell is detecting a “crack” in the membrane armor of the egg. He overcomes it and finds himself directly inside the egg.

Thus, the number of spermatozoa trapped in the vagina plays a primary role for conception. The statement that only one sperm cell is needed for fertilization is not entirely true. Millions of "tadpoles", having passed a difficult and thorny path, are thus making their way through one, the most successful.

It is not always possible to predict with accuracy how long a pregnancy occurs after ejaculation. It largely depends on the availability of ovulation, sperm motility and the gynecological health of a woman. The answer to the question of when conception occurs after the act is ambiguous. On average, it can take up to 3 days from the time the sperm enters the female body before it directly meets with the egg. However, sometimes partner sperm are so survivable that they are ready to wait for an egg for a whole week.

Day two-fourth: division

The spermatozoon and the egg cell became one, forming a zygote. It will take about 36 hours after fertilization and the zygote will begin division. While still in the fallopian tube, the zygote is now a whole cell complex. Modern medicine can accurately indicate what day the zygote division will end. After the fourth day after fertilization, the division process is considered complete. The zygote is represented by two cells - blastomeres. In size, it remains the same, although the number of blastomeres will gradually increase. The future person needs space for growth and development. The pipe becomes cramped and uncomfortable.

On the third day, the zygote has about 8 blastomeres, but still remains immovable. Лишь через сутки, на четвертый день, зигота из 16 бластомеров начинает движение в сторону матки. При этом сама бластоциста (зародыш) все четыре дня остается крохотным, практически не изменяясь в размерах. Это необходимо для удобного прохождения по маточной трубе.Full growth from this point will begin directly in the uterus.

Days Five-Seventh: The Embryo In The Uterus

The first days the woman does not suspect that such amazing events take place in her body. Meanwhile, the embryo is already moving freely across the uterus, in search of its place of residence. Choosing a convenient place for themselves, the future baby is attached to the wall of the uterus. A long and exciting journey is over. In this place he will live and develop the next 9 months.

Days Seventh-Twelfth: Implantation

Zygote is in the uterus for 5-7 days after fertilization. After several days (9-10 days following the merger), the embryo will be completely immersed in the wall of the uterus. This process is called implantation. It lasts about 40 hours. It is known for sure how many days the implantation is completed - for 12 days. From this moment on, a woman is considered pregnant.

After implantation by about the 20th day of the cycle, a woman may show certain symptoms indicating that a new life had originated in her body. These include:

  • Implant bleeding. He is often confused with menstruation. However, bleeding during implantation is less abundant and ends, as a rule, on the same day that it began. But if the spotting brown discharge lasts up to 10-14 days, the woman should immediately consult a doctor.
  • Development of hCG - a special "pregnancy hormone". It begins to be developed at 5-6 days after conception. It is because of him that a woman feels morning sick, weak or drowsy.
  • Sensitivity and swelling of the mammary glands,
  • Increased basal temperature
  • The rejection of some smells,
  • There may be tingling in the uterus or a feeling of heaviness in the lower abdomen.

All the described events occur in the body before the woman begins to delay her period or the main symptoms of pregnancy appear.

If the pregnancy is the first, the woman often blames these symptoms for a normal ailment. Ladies who were in a position earlier are usually more sensitive to such manifestations and more quickly realize their pregnancy.

Puberty

Puberty of a girl means her preparation for conception and for acquiring mother status. It begins with the appearance of menstruation, which first comes irregularly, but then the menstrual cycle is established.

On average, from the first day of menstruation to the first day of the next menstruation passes 28 days. This figure varies depending on the individuality of the physiological development of a particular girl.

  1. During menstruation, the mucous membrane of the uterus changes. The ovaries form the ovum.
  2. In the middle of the cycle, egg maturation occurs in the following way. The ovary forms 2–3 follicles, one of which grows more than the others - it is dominant. Then this follicle bursts and a ripe egg cell leaves it, which falls from the ovary into the fallopian tube, the cell is ready for fertilization by a male sperm cell - this is ovulation.
  3. When leaving the follicle, the egg forms a corpus luteum, which will ensure its implantation in case of fertilization.

The egg cell is held in the state of readiness for fertilization from 12 hours to one and a half days. If during this time it does not occur with the sperm, it dissolves in the environment.

Since the uterus mucosa is not useful for attaching a fertilized egg, it rejects as menstruation when their time comes.

Puberty boys begin to 12-13 years, when the pituitary gland begins to produce sex hormones. At the age of 15, the boy’s penis and testicle size increases, the production of sperm begins.

In the body of a man, sperm cells are formed continuously. To fertilize an egg, the sperm must go through a difficult path, bypassing the obstacles that a woman's body creates. To the probability of conception was sufficient, the male testicles form tens of millions of sperm.

How does conception happen? During intercourse, an enormous number of spermatozoa enter the vagina. Conditions in the vagina are unfavorable for male germ cells, so that not all sperm reach the goal.

How does sperm get into the womb? The fact is that in the cervix during ovulation creates an environment that permits seminal fluid (sperm). But after it, they must still overcome the uterus and 12 cm of the fallopian tube in order to reach the egg cell. The fallopian tube with an egg opens by means of a powerful blood flow. The second fallopian tube, where there is no egg at this time, is closed.

Half a billion sperms reach the back wall of the vagina. In the vagina sperm die after 2 hours. Sperm enters the uterus in an amount of at least 10 million male germ cells to fertilize an egg cell. Then they continue their way into the fallopian tube, but there an obstacle lurks them - the epithelium. Most of them become entangled in the epithelium and remain there. In it, sperm live no more than 5 days.

Spermatozoa that have passed the fallopian (uterine) tube may wait there for some time to fertilize the egg cell if it is not fully formed. Those who have passed all the obstacles and reached the egg must perform one more action - to destroy the egg membrane in order to unite with it. Nature arranged everything so that with the help of a special enzyme present in the head of the sperm, the membrane is dissolved. But this can be done only by one or several spermatozoa, since to protect against the rest, the membrane instantly changes its composition.

The ideal temperature in the fallopian tube, necessary for the interaction of germ cells of women and men - 37 degrees Celsius. All the way, a successful spermatozoon makes in 3 to 6 hours. Its connection with the egg means that the conception of the child has happened.

The moment of fertilization immediately affects the physiology of the woman, since now the main task for her is to preserve the new pregnancy.

What's next?

We talked about how the process of conceiving a child occurs. What happens next:

  1. When 2 parent cells connect, each of them has a half set of chromosomes. Upon fertilization of the egg, a new cell is formed with a unique genetic code. This first cell of a new person is called a zygote. The zygote remains unicellular during the first days after fertilization, and then begins to divide.
  2. The first week of the zygote is located inside the fallopian tube, and then begins to move to the uterus. She takes the corpus luteum with her for nutrition. At this time, the future mother’s lifestyle does not affect the fetus, since the zygote receives nourishment from a substance already formed.
  3. Having reached the uterus, the zygote finds in its wall a suitable place, where it is strengthened for further development. This action lasts for 40 hours. It is called implantation.
  4. While the egg is moving, she has time to undergo division many times. An embryo approaches the wall of the uterus. Its outer cells continue active division and conjunction with the mucous membrane of the uterus.
  5. The children's place is the environment in which the uterus mucous membrane is formed, in which the baby lives, feeds and grows. The baby itself is gradually formed from the embryonic nodule, which is formed from the internal cells of the zygote, and for its development, nutrition and growth are the placenta, the amniotic bubble and the umbilical cord, which are formed from the outer cells.

On the 13th day after conception, the amount of hormones produced by the woman — estrogen and progesterone — significantly increases. Hormones are needed for the further development of the baby. During this time period, pregnancy is easily determined using standard tests sold in a pharmacy.

Favorable days

Conception of the child occurs during ovulation, but it happens in different women on different days of the monthly cycle. Most often it is the middle of the cycle, which can vary in duration from 28 to 32 days.

If the woman goes to the gynecologist after deciding to become pregnant, the doctor will give a detailed description of the calculation of the days when conception occurs, explaining that the days of ovulation can be determined most accurately by measuring the temperature every morning in the rectum or in the vagina. On ordinary days, the temperature should be 36.6 degrees, and during ovulation it rises to 37 degrees. If the expectant mother will observe and mark her temperature on the graph for several months (the Y axis is the temperature, the X axis is the days of the month in order), then she can build a curve that shows which day of the cycle she is on. ovulation.

Gynecologists believe that planning a pregnancy is a good idea to spend six months. During this time, a woman will not only build a chart describing the basal temperature, but also future parents will be able to undergo a medical examination and identify diseases that must be treated before conception.

There are no signs of ovulation requiring prolonged observation:

  • During this period, a woman appears discharge, similar to raw chicken protein.
  • Many ladies swell breasts, felt some distention breast.
  • A woman has a greater sense of sexual attraction. Nature herself tells her the days that are suitable for creating a new life.

Ovulation Day can be found by ultrasound. An experienced ultrasound technician will notice that the follicle has matured and burst, and fluid from the follicle has appeared in the back of the uterus.

Also now there are tests similar to pregnancy tests that determine the day of ovulation.

Tests are arranged in a similar way, this is a strip of paper that needs to be immersed in a jar with a woman's urine. 2 lines on paper change color depending on the amount of estrogen in the body. If it is far from ovulation, only one line will change color. 1 day before ovulation both strips will be bright. So the next day is favorable for conception.

Lifestyles in the period of conception

For children to be born healthy, it is not enough for parents to undergo a medical examination and cure the diseases found. It is necessary:

  1. Refuse to take alcohol.
  2. Quit smoking habit.
  3. Drugs excluded. If one of the parents has consumed them, it is necessary to consult a psychiatrist before planning conception.
  4. Do not take any medication. If the woman is unwell, consult your doctor about how to recover in the safest way. After all, conception could already occur. And the pills taken by mom are harmful to the baby. In case the conception has not yet happened, set aside love joys until recovery. The adoption of drugs by the father immediately before conception is also unhealthy for the developing organism.
  5. Do not self-medicate, consult a doctor even with a common cold.
  6. Try not to be nervous, avoid stress.
  7. Sleep at night without interruption should be at least 8 hours. It is not bad for a woman to allow herself an easy afternoon nap. Unfortunately, working ladies cannot do this.
  8. Eat right. Food should include all the necessary human substances, vitamins, trace elements. Do not overeat, abandon spicy, fatty foods. Sweet and flour allow yourself occasionally and little by little.
  9. It is contraindicated to attend steam baths.
  10. Playing sports is not bad, but traumatic sports should be excluded.
  11. Do not wear too tight underwear.

If sex is present in the life of a couple at a frequency of 2-3 times a week, then it can take from six months to a year to conceive.

All this time, both parents must for the future baby lead a correct lifestyle. A woman and a man must understand how a child is conceived in order to take these recommendations seriously.

First signs of pregnancy

The easiest way to recognize the onset of conception is the absence of menstruation. But delayed menstruation can happen for other reasons.

What else says about the coming pregnancy:

  • Increased vaginal temperature (basal temperature).
  • Breast swelling.
  • Frequent urge to urinate.
  • Taste changes. The fact that a woman ate with pleasure, now she does not like, and vice versa.
  • Daytime sleepiness, fatigue.
  • In some pregnant women, nausea begins almost immediately after conception.
  • Even a sudden runny nose may indicate a pregnancy.

If you have several of these signs, congratulate yourself - you are pregnant!

What is the conception of a child

So, with the successful conception fertilization of the egg takes place, and a new life is born in the female body. Fertility is a determining factor, i.e. the ability of women to natural childbirth. Some young ladies of reproductive age manage to become pregnant at a rapid pace, others have to be treated and for several years have unsuccessfully planned motherhood. When the pregnancy begins, a completely different, equally exciting life begins.

When conception comes

It is important to understand the essence of the physiological process: a huge number of sperm along the 15-cm path travel at a speed of 3 mm per minute into the uterine cavity. A favorable period for the onset of pregnancy is ovulation, when the egg is only waiting for contact with sperm. It is known that in some cases it takes no more than an hour to complete the process, and in others - 2-3 days after unprotected sex. Further, the probability of conception is reduced, and the birth of a new life is transferred to the next ovulation period.

To make pregnancy planning methods particularly successful, it is important to be aware of the conditions for successful conception and ensure their presence in your case. It:

  • physical and moral readiness,
  • sufficient sperm motility,
  • moderate body fat accumulation in the figure,
  • normal environment in the vagina,
  • good nutrition
  • rejection of bad habits,
  • no genitourinary infections
  • easy way of embryo adoption
  • a sufficient number of sexual acts in the expected period of ovulation,
  • optimal conditions for the fusion of the egg,
  • permissible hormone levels, lack of endocrine pathologies.

Conception planning

In order to conceive a child, many women regularly measure basal temperature, and this knowledge increases their chances of successful fertilization of the egg several times. As such, there is no specific date of conception, since active sperm can be fertilized by the female egg within an hour after sexual intercourse, or several days later. The same convention can be attributed to the release of the egg after maturation. Therefore, if you clearly adhere to the calendar of conception, you can not get pregnant by the "wave of a magic wand."

Choosing the desired sex is also practiced among future moms, but experience shows that this is impossible. A woman’s desire to conceive a boy or a girl is in fact determined by the genetic data of the male germ cells, which fertilizes the egg. It is not possible to predict this natural process. Theoretically, in order to conceive a girl, the sperm cell should fertilize the female reproductive cell, for the conception of the boy - the male.

How many days do sperm mature

Before you conceive a child, it is necessary to approach this issue with all responsibility, for example, a man will have to give up drinking alcohol and not be addicted to smoking anymore. The activity and the period of maturation of spermatozoids, the quality of sexual intercourse, and its duration depend on it. Otherwise, success will not come in a few months.

Frequent sex is not conducive to the successful conception and the onset of the long-awaited pregnancy, because the sperm does not have time to be produced by the body in the required amount. As a result, an insignificant amount of spermatozoa enters the vagina, and large volumes of seminal fluid simply flow out. Therefore, sperm need time to mature, and doctors when planning maternity strongly recommend to refrain from intimacy for 5 days before the arrival of ovulation.

How is conceiving a child

A big deal in this matter will be the ovary, in which the follicle matures. Later it breaks, and the egg cell leaves, which the most active sperm cell safely inseminates. Up to this point, it goes a long way, first penetrating into the uterine cavity, and then into the space of the fallopian tubes. After the confluence of the male and female germ cells, a zygote is formed, which enters the uterine cavity after 7-8 days. Until that moment, she remains in "free swimming". Next comes the attachment of the embryo to the wall of the uterus, and its size during this period is not more than 1.5 mm.

How does the fertilization of the egg by day

It is important to know not only the duration of the menstrual cycles, and to be able to calculate ovulation, but also to determine unfavorable days for conception, if the plans do not contain thoughts about motherhood. When a woman wants a baby, information on how fertilization takes place on days will be helpful. The scheme below provides an answer to this question in detail. So:

  • 1 day - one of the strongest sperm penetrates into the egg, fertilization occurs.
  • 2-3 day - after conception, the egg cell is divided into 2 cells, which are called blastomeres. Этот процесс продолжается еще 12-16 часов.
  • 4 день – 16 клеток объединяются в зародыш, после чего он проникает в маточные трубы.
  • 5 day - the embryo penetrates into the uterus, is attached to the wall, resulting in a woman's basal temperature rises.
  • Day 10 - primary and secondary fibers are formed, which will later become the umbilical cord and placenta.
  • 12 day - the implantation of the ovum ends.
  • Day 14 - there is a jump in progesterone and estrogen, which provokes the appearance of signs of pregnancy.

How to conceive a child

Having sex without a condom to continue offspring is recommended only after the completion of the family planning phase. Only in this case, the time after the successful conception and until the birth of the baby will be the happiest in the lives of young parents. Here are the general recommendations of qualified professionals, how to have a child in a timely and correct manner:

  1. It is recommended 3-5 days before ovulation to exclude sex, so that spermatozoa matured.
  2. For conception, a woman should choose a position lying on her back, and after intercourse, put a pillow under the buttocks and lift her legs to the "birch".
  3. It is recommended to have sex on favorable days for conception, i.e. 12-14 days of the menstrual cycle.
  4. To conceive a child to be successful, it is recommended to eat less fat, flour and sweet, more natural vitamins.
  5. To give up bad habits, which even after a successful conception can become a serious threat to miscarriage.

Unfavorable days

A few days (3-5) after the end of planned menstruation and 5 days before her arrival, the probability of conceiving a child is low for a woman. In the first days of the menstrual cycle, this is due to an unripe egg cell, and in the latter days - by its inability to fertilize. It is recommended to have sex on the 12-14 day of the menstrual cycle, this period accounts for a high frequency of pregnancies.

The probability of conceiving a child after menstruation

After the end of bleeding, another 2-3 days give the couple in love the right to have safe sex. This is explained by the gradual maturation of the egg, which is not yet ready for fertilization. Starting from the 10th day of the menstrual cycle, the days become favorable for conception, and it's time to try to make the baby, clearly following the above recommendations.

Incompatibility at conception

Photos of young children are always touching and inspiring, however, there are cases when between sexual partners there is a complete incompatibility at conception. Among the common causes are psychological trauma, immunological incompatibility, antisperm antibodies, Rhesus conflict. Such pathogenic factors prevent the fetus from developing, and it suddenly dies. It is recommended to pass a compatibility test.

What is stimulation for conception

These are therapeutic measures aimed at fertilization by force. Well-known drug and alternative stimulation, are carried out for medical reasons, with diseases. The need for additional assistance arises if, with regular unprotected sex for more than 1 year, it is impossible to conceive a fetus in a natural way.

Analysis of hCG after conception to determine the presence of pregnancy

In this case, we are talking about a classic test strip from a pharmacy. This publicly available method for diagnosing progressive pregnancy is effective from the first day of delay and beyond. Testing the likelihood of successful fertilization of the female reproductive organ at an earlier date gives a false result, since the concentration of hCG hormones is still insufficient.

Days Thirteen to Twentieth: Delay

The most important sign by which a woman finds out about her pregnancy is a delayed menstruation. If it does not start on a certain day of the cycle, you can suspect pregnancy. Sometimes the delay can be caused by irregular menstruation. One way or another, a woman should do a test to make sure her guesses are correct.

This period corresponds to approximately 5 weeks of pregnancy. At this time, the fetus is still quite small - its size does not exceed 7 mm, and its weight is 4 g. But the doctor on ultrasound can already see it. The future person himself at this time resembles the shape of the letter C. Despite its tiny size, with careful consideration on the monitor, you can see the processes - future arms and legs. Sometimes it is possible to distinguish even small tubercles in the region of the apical processes — future fingers.

Facial contours also begin to appear in this period: dimples of the eyes and cheeks, nasal and oral slits. The tiny embryo floats freely in the amniotic fluid, which begins to be produced by about 5 weeks.

It was during this period that the beginnings of the internal organs of the future person begin to form. At the initial stage of formation are the respiratory, circulatory and nervous systems. The cells of a small organism continue to actively divide. Very soon the heart of the future baby will begin its work.

How to protect the baby

It often happens that a woman finds out about her pregnancy before the results of the test and consultation with a doctor. Female intuition tells the future mother that a new life is ripening inside her. But this is not always the case, and many women do not realize their position.

The first days and weeks are considered the most dangerous period for the future baby. After all, a potential pregnancy can end at any initial stage. That is why a woman should worry about her health and help her body in every possible way to accept a tiny creature.

To do this, you should follow some recommendations:

  • Preparing for conception is well in advance. For several months (ideally - six months), potential parents should stop smoking, drinking alcohol and other bad habits.
  • Expectant mothers need to be carefully examined in order to study their female health. The presence of inflammation or adhesions in the uterus or in the tubes can lead to dire consequences. A fertilized egg, without passing through the adhesion barrier, can begin to develop in the fallopian tube and further lead to its rupture (ectopic pregnancy).
  • A woman is recommended to drink a complex of vitamins before conception. Especially recommended to future mothers drugs with folic acid and vitamin E. They significantly increase fertility (the ability to conceive).
  • Proper nutrition should be a companion of women for the entire period of pregnancy. Harmful foods should be excluded from the diet, but water, on the contrary, should not be neglected.
  • Potential mom categorically does not recommend serious physical exertion. Weight lifting is also worth refusing. You can train in maintaining a calm lifestyle even before conception - the future mother's movements should be smooth, unhurried, and soft.

Pregnancy is a complex and simple process at the same time. Difficult it in view of the fact that the baby goes a long way from the merger of two cells to birth. And at the same time, nature has simplified everything and thought it through - the process of conceiving a child and its further development is thought out almost every day. From the future mother, only a little effort and unconditional love for the creature inside is required to make carrying the child as simple and pleasant as possible.

Male reproductive system

Couples wonder how is conceived. The process of conception is accompanied by the merging of the parent germ cells. The man is involved in this sperm. Sperm cells are produced in the paired gonads. The testicles produce daily germ cells. A foundation is needed to thin the seminal fluid. It is formed in the prostate gland. Under the influence of the work of smooth muscles, seminal fluid is discharged into the urethra and enters the female reproductive system.

It was found that the chromosome carried by the sperm cell is responsible for the sex of the child. For the birth of a boy, sex cells bearing the XY chromosomes are necessary. These substances affect the functioning of the sperm. Boy sperm have high mobility. They are able to enter the uterus during the first days after intercourse. Also due to this, they have a short lifespan. The average activity is 48 hours. After that they die.

Sperm cells with XX chromosomes are suitable for the birth of a girl. These germ cells move very slowly. They need time to enter the uterus. This feature is compensated by long-term viability. Such germ cells can remain active for more than five days. When asked whether it is possible to conceive a child of a certain gender, experts advise to pay attention to this phenomenon. These data allow you to know how to conceive a child of a particular sex.

The work of the female body

Before you conceive a child, you need to establish the presence of fertility in women. For the formation of the embryo requires an egg. It matures in the ovary every month. Cell maturation depends entirely on the work of the hormonal system.

The menstrual cycle consists of three parts. They are called phases. The first stage is responsible for several important processes:

  • gestation maturation
  • preparation of the uterus for conception.

Preparation of the uterus is the formation of the endometrial layer. This fabric during the entire cycle has different properties. After menstruation, the fabric is a uniform thin layer that is not very thick. Under the influence of estrogen, the endometrium gradually increases. The fabric begins to be divided into several layers. For the onset of conception, the endometrium must be at least 11 mm thick. This will allow the egg to firmly consolidate in the wall of the uterus.

The formation of an egg occurs under the influence of follicle-stimulating hormone. The substance appears in the bloodstream at the end of the first week of the menstrual cycle. Under his influence, the cell leaves the cavity of the ovary and enters its shell. Under the shell accumulates fluid. The ovum and fluid form a follicle. Hormone causes active growth of the follicle.

From the second week of the cycle, the luteinizing hormone replaces the follicle-stimulating substance. It gradually increases in quantity. On the 4–5th day there is a sharp increase in its level. Luteinizing hormone causes an increase in follicular fluid volume. It exerts strong pressure on the walls of the follicle. They burst. This phenomenon explains what the ovulatory phase is. In determining ovulation, a couple may know on which day fertilization takes place.

Time of pregnancy

Planning couples are interested in how much conception occurs after the act. Fertilization of the cell occurs in the fallopian tubes. In her egg falls after the rupture of the follicle during the first day. This is a good time to conceive a child. During this day, the cell passes the abdominal cavity. It is recommended to conceive at this time. Under the influence of smooth muscles, the cell moves in the direction of the pipes and enters their cavity. When cells merge with the sperm cell, a zygote is formed. The zygote has an uneven structure. It should contribute to more rapid progress of the zygote through the hairy layer of the fallopian tube. The villi move the zygote toward the uterine cavity. Relocation occurs within 2-3 days.

After the zygote enters the uterine cavity, it is introduced into the endometrial tissue. It gradually deepens into the endometrial layers and falls to the wall of the uterus. The tissue allows the cell to more tightly adhere to the uterine wall. The whole process takes 1-2 days.

From the moment of ovulation, the cell goes a long way. The total time of moving and fixing is 5–6 days. From this moment comes the pregnancy. This time may be shorter or longer. Terms of conception in different women are individual. After how many days conception occurs, only a specialist can answer during the inspection.

Signs of pregnancy

Patients are asked how to find out if conception has occurred. In order for a woman to know how to understand whether conception has occurred, she must pay attention to a number of signs. The following first signs of conception are distinguished:

  • the appearance of blood in the cervical mucus,
  • soreness in the lower abdomen,
  • change in psychological state.

Not many patients can pay attention to the listed symptoms. Some women have such conception symptoms as blood in the cervical secretion. On the day when conception occurs, a zygote is inserted into the uterine wall. The walls of the uterine cavity permeated with a large number of blood vessels. When the zygote penetrates the wall, part of the vascular fibers is damaged. After conception, blood enters the uterine cavity from the vessels. With a large volume of blood liquid, mucus turns pink. A woman notices such signs of conception as discoloration of cervical secretion. But this process is not mandatory for all women.

Has conception symptoms due to implantation. During implantation, pain may occur in the lower abdomen. Pain can occur due to damage to the uterine wall. This symptom appears when the zygote is attached to the front wall. Also a symptom may occur on the day of ovulation. The process of conceiving a child can be recognized by the presence of pain during the appearance of the egg from the follicle shell. From this point on, a woman can determine how long it will take to develop a pregnancy. What matters is the location of the pain.

A woman should be able to guess about the conception of a child by changing the psychological state. The process that has occurred causes various changes in the body. A few days after conception, the hormonal system is rearranged. Progesterone is responsible for the development of the embryo. This hormone appears in the blood from the moment zygote is attached. Its main volume is in the yellow body. It should be formed in place of a bursting follicle. Under the influence of progesterone there is a change in psycho-emotional state. Conception in women is accompanied by tearfulness, irritability and drowsiness. After the disappearance of the corpus luteum, this symptom disappears. These symptoms determine whether or not implantation has occurred.

Conditions to speed up the process

Couples ask how quickly conception occurs. To this end, you must follow the rules of conception. Both future parents need them.

A man must observe the following points:

  • rare sex,
  • avoiding alcohol and smoking
  • active physical activity
  • medical examination.

Seminal fluid is able to quickly change their qualities. Various factors have a negative effect on its characteristics. To conceive a child is successful, you need to observe sexual peace. Before the fertile period, it is not recommended to have sex for a week. From the moment of the onset of the ovulatory phase, sexual contact should take place every other day. After pa there is a decrease in the concentration of seminal fluid. The break contributes to the accumulation of mature and motile sperm in the fluid. The accumulation of healthy germ cells increases the concentration of seminal fluid, which contributes to conception.

Since spermatozoa are sensitive to any negative effects, you should stop drinking alcohol before planning. Alcohol-containing drinks have a detrimental effect on semen. If a man has long abused alcohol, a break in planning for 3-4 months is recommended. This will help the body to cleanse decay products and recover.

To get it all you need to conduct active physical activity. Conception can only happen during normal functioning of the reproductive system. Active physical activity increases metabolic processes in the pelvis. Acceleration of blood circulation causes the flow of oxygen to the tissues. This allows cells to multiply more actively. Sperm is updated faster, which affects the conception of the child.

Also, before planning, you need to undergo an examination by a specialist. The doctor must conduct a full examination. Medical monitoring will determine the status of the male reproductive system and its ability to fertilize. This will allow planning to go faster.

Useful recommendations

A woman is also given advice for conception. Tips for conceiving a child include the following guidelines:

  • tracking ovulation
  • taking a certain posture after conception,
  • use of vitamin complexes
  • proper nutrition and physical activity.

Pregnancy can occur only in the ovulatory period. For its establishment may require different methods. The main method is to build a graph of temperature indicators. It is measured daily in the colon. The data obtained are recorded in a table. Plotting lasts for the entire menstrual period. After conception, it is also recommended to take a measurement in order to make sure that conception has come and managed to become pregnant.

After conception, it is recommended to maintain physical peace. A woman should lie 20 minutes after intercourse. Она должна понимать, что любое движение может вызвать выведение семенной жидкости из влагалища. Чтобы зачатие произошло специалисты советуют принимать позу березки. Этот совет, способствующий наступлению беременности, используют многие планирующие пары.The adoption of this position allows the seminal fluid to quickly enter the uterine cavity. In this case, conception can be faster. Other methods of conception are also used.

A variety of vitamin and mineral complexes can also affect the process. Vitamins should be taken by day of the menstrual cycle. The order of admission and the type of medication should be carried out by a doctor. Do it yourself should not. A woman does not know what is happening under the influence of certain vitamins. The process of conceiving a child may be disrupted.

There are other factors that influence the onset of fertilization. A woman should know that you need to eat right. When planning is not recommended fried, fatty and salty foods. You should also abandon the use of spices. The patient must be active. This contributes to the strengthening of metabolic processes.

These conditions are taken into account when planning a second pregnancy. Conception of the second child should also be carried out through timely preparation of parents.

Modern physicians often face a complaint that children do not work for a long time. To determine the cause of the disease, you must visit the hospital and study the process of the onset of conception.

What it is?

Conception of a child is a very complex biological, chemical process, in which not all can be explained only from the point of view of physiology. In conception there is always something of a divine principle that cannot be measured or counted. Thanks to him, conception sometimes comes in a miraculous way for those who, from the point of view of medicine, should not have it.

In medicine, conception is called the moment of fertilization of the female germ cell - the egg cell by the male cell - the sperm cell. It is from this moment that the beginning of the actual pregnancy is considered, from this point of reference its embryonic gestational period begins. Obstetric term is counted from the first day of the last before pregnancy menstruation. Thus, by the time of conception, which usually becomes possible during the period of ovulation, a woman already has 2-3 obstetric weeks of pregnancy. Medical determination of the onset of pregnancy hardly reveals the whole meaning of this amazing process.

In a woman's body, the changes begin from the very first tenths of a second, as soon as the germ cells merge. The process of fertilization starts a cascade of changes aimed at creating the most comfortable conditions for the maintenance and development of a new life.

Changes in the body after fertilization

Immediately after the egg is fertilized, a large-scale operation in the body unfolds to create new conditions that are most optimal for the development of a new life. In large quantities, the hormone progesterone begins to be produced. Its task is to make the walls of the uterus more friable, so that the embryo can consolidate on one of them without any problems and “grow” into the tissues. This place will then become the basis for the placenta.

Under the action of progesterone from the first minutes after conception, the metabolic processes begin to flow somewhat faster. Of course, a woman will not be able to feel these changes, at least in the first couple of weeks after fertilization.

Progesterone provides everything for the development of the baby - it suppresses maternal immunity, so that “by mistake” does not take the embryo as something alien and does not destroy it. Under the influence of this hormone, the uterine muscles relax and its tone decreases, which ensures pregnancy.

The cervix also from the first minutes after conception reacts to innovations and begins to fulfill its role. The cervical canal inside it, which on the day of ovulation is ajar and provides sperm transfer from the vagina, immediately closes, filling with thick mucus.

This mucus plug will protect the uterine cavity from viruses, pathogenic bacteria and other unwanted penetrations throughout pregnancy. Only before the birth mucus plug will leave its place. Her discharge relates to the category of precursors of imminent labor.

At the cellular level, a lot of interesting things happen. During the first 30 hours after conception, the zygote, which has become an egg cell that fused with the sperm cell, starts forming nuclei. It is constantly being crushed, which means that the number of cells is increasing, and the size of the cell is not, just new cells are smaller. The crushing period lasts about three days. All this time, after intercourse and fertilization, the zygote is in constant motion - it seeks to get through the uterus.

On day 4, the embryo consists of approximately 16 cells. Blastomeres begin to divide into the inner and outer layer. On the 5th day after conception, the zygote changes its status and becomes a blastocyst. There are about 30 cells in it at the very beginning and already about 200 cells by the end of the stage. The blastocyst has a round spherical shape. This is exactly what a former egg looks like at the time of embryo implantation.

Embryo implantation

Implantation is the process of introducing a blastocyst into the tissue of the uterine wall. The embryo is usually attached a week after conception, often at 7-8 days after fertilization. From this moment on, the chorionic gonadotropic hormone, which is also called the pregnancy hormone, begins to be produced in a woman’s body, and determining its concentration is the basis of all currently existing pregnancy tests.

So that contact with the endometrium was more dense and the “docking” was successful, the blastocyst gets rid of the shiny shell immediately after the fertilized egg descends into the uterus. The attachment of the ovum is a signal to begin the active work of the corpus luteum of the ovary. Now, progesterone is produced even more, because the main task of the entire female body is to keep the pregnancy.

A prerequisite for implantation is the level of pregnancy-supporting progesterone in the blood, as well as the viability of the fetus itself. If a baby with genetic errors is conceived, then with a high degree of probability the implantation will be unsuccessful, the fertilized egg will be rejected.

Implantation sensations are also purely individual. Some women do not even know what important processes occur in their bodies, others may notice that about a week after ovulation, they began to get tired faster, and their mood changes as the weather in the coastal city. On the day of implantation, a small amount of blood smears of blood may appear, associated with endometrial integrity problems. Implant bleeding does not last long - no more than a day. That it is the first obvious sign of pregnancy before the delay.

Not everyone can feel the implantation, implantation bleeding may not occur. In any case, a week after implantation in the blood and urine of pregnancy, the concentration of chorionic gonadotropin reaches a sufficient level so that the fact of new life can be determined by laboratory analysis of blood for hCG or a test strip, which can be easily purchased at any pharmacy or even in a supermarket.

On women's forums you can find descriptions of feelings after conception. Usually they are left by women who dream of becoming pregnant and have been trying to conceive a baby for quite a long time. Such women often describe that the chest began to hurt almost the next day after intercourse, that the lower abdomen hurts after the alleged conception. Physicians tend to call such feelings psychogenic, since there are no objective reasons for such pains and symptoms.

Progesterone, even if the conception was successful, is still not so much that the chest aches and grows at a rapid pace, and the pulling pains in the lower abdomen are hardly associated with cellular processes that are still occurring only in the fallopian tube.

In theory, everything sounds rather optimistic, but in practice, the conception and subsequent transportation of a fertilized egg into the uterine cavity can proceed with impairments. In most cases, these violations lead to abortion at the earliest possible time. Some women may even remain unaware that they were pregnant. It’s just that two or three days are delayed by regular menstrual periods, and the fact that they are slightly more abundant than usual, women, as a rule, do not pay much attention.

Difficulties can arise at the very initial stage - poor quality of the egg or violation of the properties of sperm can prevent conception, even if sexual intercourse is carried out directly at the time of ovulation.

Chronic diseases of the gynecological profile, genital infections, ovarian dysfunction, addiction to alcohol or nicotine can influence the female body. Also, any woman has anovulatory cycles - months in which ovulation does not occur at all.

On the part of men, hormonal disorders, radiation exposure, harmful substances, alcohol and drugs, prostatitis, varicocele, genital infectious diseases, and venereal diseases can be causes of infertility. Even with a banal cold, which one of the partners suffers at the time of intercourse, the probability of conception decreases.

Problems may arise at the stage of fertilization itself. If more than one sperm cell penetrates the egg cell, a triploid embryo is formed that is not capable of development and growth, since its genetic set will differ from the normal set of 46 chromosomes. Genetic pathologies can also occur if fertilization produces a sperm cell with an altered morphology — a deformed or forked head, an impaired acrosome, mutations and deformities of the tail.

Such an embryo will develop as much as a specific genomic anomaly allows. Most often, such a pregnancy ends in miscarriage, spontaneous abortion in the earliest terms, less often during the first trimester of pregnancy.

Unpredictable difficulties may also arise at the transport stage The movement of the egg into the uterus provides special villi inside the tube, the egg itself is the largest and most fixed cell of the human body.

If the mobility of the villi is impaired due to inflammatory diseases of the female reproductive system, if the patency of the uterine lumen is impaired, the zygote may remain in the fallopian tube and gain a foothold in the absence of an alternative in it 7-8 days after conception. Then an ectopic pregnancy develops. After its detection, the embryo is removed surgically, since it represents a serious danger to the mother's life - rupture of the fallopian tube leads to severe internal bleeding, which often leads to the death of a woman before the arrival of the Emergency Room.
