Every woman when planning pregnancy is faced with the concept of ovulation. Conception without it is impossiblehowever frequent the sex life is.
In order for a pregnancy to take place, it is very important to know when this process takes place, its durationWhat is the longevity of a single egg?
What is a female egg?
The egg cell is the most large and long-lived cell in the female body. It is after her fertilization comes the long-awaited pregnancy.
It contains many different nutrients. This is necessary in order for the embryo to have something to eat after conception until the placenta begins to work.
A future woman still in the womb gets her set of eggs for life. When a woman reaches puberty, one part of them dies, and the other gets the opportunity to ripen under the influence of sex hormones. For all life in the female body matures about 400 eggs ready for fertilization.
- In the body of every healthy woman of childbearing age, several follicles grow in the ovaries every month with the start of a new menstrual cycle.
What is ovulation?
Ovulation is the release of a mature egg. This happens after the follicle exploded, in which she matured to full readiness. After exiting the follicle, the egg will enter the fallopian tube from the ovary and will wait a few hours or days (depending on what is her life span) meeting with the spermatozoon for further fertilization.
Usually, ovulation with a 28-day cycle occurs in the middle of it, which is usually 14 days. However, the body of each woman is individual, the cycle may be longer or shorter, and ovulation may occur later or earlier than expected, or may be completely absent. In addition, many factors affect the maturation of the egg.
How much does an egg live after ovulation?
As soon as the egg cell finally matured and came out after the rupture of the follicle, the duration of its life is quite short. She is up only 12 - 24 hours. In rare cases, the viability of the egg possible up to 48 hours. The family planning the child is very important to have an idea of when this important cell matures. After all, the time of its occurrence is the most suitable for conceiving a baby.
To conceive succeeded, doctors recommend sexual intercourse in a few days before and during the estimated date of ovulation, since the lifespan of sperm cells is much longer (3-4 days, and sometimes can reach seven days).
How can you determine the maturation of the egg?
Today there are quite high-precision methods for determining the date of ovulation. It can be determined at home or by laboratory:
- the day of the attack can be determined by Ultrasound (such a study will not only establish the exact date, but also help you create an individual ovulation calendar)
- On the eve of changing the density and nature of discharge. If the egg is ready for fertilization, the excretion increases and acquires raw egg density,
Knowledge of the ovulation date is very important indicatorwhen planning pregnancy. Pregnancy occurs at the very moment when the egg is fully ripe and ready for fertilization. The life of the egg is very small, so the couple has a little time to get a positive result.
Ovogenesis - the development of the egg
Ovulatory process is quite complicated. Ovogenesis is called cell maturation throughout the entire cycle.
In a woman's body, an egg after ovulation (oocyte) will last no more than 24 hours. For any duration of the cycle, this process occurs 12–15 days before the start of the menstrual period.
Oocytes are immature oocytes that pass through successive stages during maturation. Their growth provokes physiological changes in the uterus.
In the body of a newborn girl is more than 2 million eggs (first-order oocytes), which are distributed between 2 ovaries. As they grow older, their number decreases. By the onset of menopause, the process of cell development in the ovaries is completed.
They develop in complete secretory structures - follicles. In the first stage of oogenesis, oogony is surrounded by layers of granular cells. As for the genetic material that is present inside the egg, it remains intact, but until the middle of the month will be susceptible to change. The duration of this period is 43–45 years.
During the monthly cycle, about 20 follicles mature, of which only 1 develops.
Ovulation - what is it
Ovulation is a physiological phenomenon that is characterized by the release of an oocyte from the ovary. The female cell enters the fallopian tube, causing the follicle to burst.
The moment of the exit of the cell into the tube of the uterus is quite painful. The ovulation period in women is accompanied by the appearance of pulling pains in the lower abdomen and in the area of the mammary glands.
According to gynecologists, this is a changeable process that is influenced by various factors, such as stress, physical stress, and infectious diseases.
Despite the rapid ovarian production of oocytes, only some of them can ovulate. The chances of successful fertilization of the cell increase at the reproductive age (16-30 years).
During this period, women experience painful sensations in the chest and lower abdomen, occurring in different parts of the body, mainly in the abdomen. If the egg has not been fertilized, the uterine endometrium exfoliates - menstruation occurs. It can begin even in the absence of ovulation.
Where does an egg live after ovulation and how much
Information about what happens to the egg after ovulation, will be useful to anyone who is planning a pregnancy.
When the egg leaves the fallopian tube, it lives 12 hours. Sometimes the duration of her life is increased to 24 hours. The viability of the egg depends on the physiological characteristics of the organism.
In the third trimester of the cycle, the unfertilized cell enters the fallopian tube, waiting for a meeting with the sperm. This occurs around the 15th day of the menstrual cycle. If fertilization has not occurred, it is removed from the body along with the uterine epithelium and blood.
Then the uterine epithelium is renewed, and a new egg matures in the ovaries. The next menstrual cycle begins in a woman. Lack of ovulation is a physiological abnormality indicating health problems.
How to determine ovulation and quickly conceive a child
In the middle of the monthly cycle, the probability of pregnancy is highest. When planning the conception of a child, it is necessary to know how many days the egg lives. Above it has been said that after ovulation, her life span is 12 to 24 hours. The spermatozoon, which is in the fallopian tube at this time, retains the ability to fertilize for 2–3 days.
A woman planning a pregnancy should know that fertilization takes place a few days before ovulation, that is, approximately on the 12-13th day of the monthly cycle. A fertilized egg is a guarantee of the onset of pregnancy.
To determine ovulation, gynecologists advise women to measure their basal body temperature. During this period, it increases slightly. Specific vaginal discharge (sticky and slippery) also speak about its occurrence.
Couples planning a pregnancy should have sex in the ovulation period, which occurs approximately on the 12-15th day of the monthly cycle. About the release of the egg into the tube of the uterus shows the manifestation of such symptoms:
- Increased sexual desire.
- Pulling and aching discomfort that occurs in the lower abdomen.
- Discoloration of vaginal discharge.
- Excretion by the uterine neck of large amounts of mucus.
It should be noted that not all women in the middle of the monthly cycle have painful sensations in the lower abdomen. Therefore, in their absence, a clear sign of the beginning of this period is sexual desire.
Discomfort has little effect on sexuality. The emergence of a strong sexual desire in a woman is a signal that the body has created favorable conditions for fertilization. This is also evidenced by the specifics of vaginal discharge. First, they begin 1-2 hours before the onset of the middle of the menstrual cycle and last for about 2 days. Secondly, they become more liquid and sticky.
Sometimes in the middle of a monthly cycle reddish clots come out of the vagina. This is normal. However, the release of large amounts of blood is an alarming symptom. In this case, fertilization of the cell is recommended to postpone.
These symptoms can determine the beginning of the ovulation period, and then plan the conception of the child.
Features of the ovulation process
Under the influence of luteinizing hormone, the oocyte grows and matures. When the maximum concentration of a substance is reached, the walls of the dominant follicle are broken, and the egg, ready to fertilize, leaves the ovary.
The female reproductive cell is sent to the fallopian tube, where it waits several hours or days to meet with the spermatozoa for probable conception. When pregnancy does not happen, the duration of life is dramatically reduced, and it dies. The remains of the oocyte fall into the uterine cavity, along with the menstrual secretions.
If the menstrual cycle lasts 28 days, ovulation will occur on the 14th day. The cycle duration for women is individual, and the cherished day may come earlier or later than the expected date.
By listening to her own body, the girl is able to understand that the egg is ready to fertilize.
The best time for conception is characterized by the following signs:
- The appearance of a slight pain in the lower abdomen or a tingling sensation in the side.
- Swelling, hypersensitivity of the mammary glands.
- The formation of transparent vaginal discharge, odorless.
- A sharp increase in desire in male attention.
Healthy women experience these symptoms monthly at one time. In girls with an irregular cycle, symptoms occur on different days.

How much does an egg cell after leaving the follicle
When the female reproductive cell finally matures and leaves the ovary, its lifespan is short. It is equal to 12-24 hours, although sometimes it reaches 36 and even 48 hours.
How much an egg will live depends on certain conditions:
- whether the functional usefulness of the genetic material and structural proteins of the germ cell is preserved,
- how many substances accumulated in the preovulatory period, it contains,
- the presence of a woman's individual characteristics that determine the basic life program of oocytes.
How many hours is the egg ready for fertilization
A mature female reproductive cell can fertilize within 12-24 hours after leaving the follicle. When a couple plans to have a baby, ovulation is the best time to conceive. At this time, the probability of becoming pregnant reaches a maximum, and with each hour the chances of fertilization decrease.
The sperm reaches the fallopian tubes at least 3-4 hours after sexual contact. The male gamete additionally takes time to dissolve the shell of the egg. Sexual acts must be performed a few days before and during the intended ovulation. This will increase the chances of conceiving a baby.
Why does this need to know future parents
When a couple has problems with pregnancy, it is necessary to delve into the fertilization process. Since only 1 egg matures for 1 menstrual cycle, partners calculate how many days it lives. Knowledge of the ovulation date is important information for future parents planning a pregnancy: this period has the highest chances to conceive a long-awaited child.
Spouses use various methods to determine the maturation of the oocyte - the traditional counting of the cherished day, ovulation tests, basal temperature measurement or medical examination with ultrasound diagnostics.
The term viability of the female reproductive cell is small. To achieve a positive result, future parents keep track of the coveted day.
How does a woman's age affect the life span of an egg
The older the woman, the shorter the life of the oocytes. If you compare 30-and 40-year-old ladies, the difference will be significant. It is easier for young people to get pregnant because their sex gametes have a normal structure and live for more than a day. This greatly increases the likelihood of fertilization.
In women who have stepped over 40 years of age, the menstrual cycle happens without ovulation or physiologically defective oocytes are formed. The rupture of the wall of the follicle without the release of an egg cell is possible, or its death occurs within a few hours after ovulation.
Doctors recommend not to delay the conception of the first child, and give birth to him before the onset of 35-40 years. The possibility of becoming pregnant in women of this age category is greatly reduced.
What else affects the life of the egg
Increasingly, couples experiencing a problem with pregnancy. Oocytes are very sensitive to adverse conditions. Negative factors cause early death of the female germ cell, impairing the ability to fertilize and halve their viability.
The main harmful factors provoking the early death of female gametes:
- Stress. Nervous overstrain leads to hormonal failure, which shortens the life of the egg.
- Inflammatory diseases of the ovaries. An infectious lesion of an organ of the reproductive system is fraught with the formation of an inferior female germ cell, causing a reduction in its life.
- Violation of hormonal levels. Diseases of the thyroid gland lead to a short life of oocytes. Hormonal failure develops, as a result of which the girl has a problem with conception.
- Alcohol. Alcoholic beverages cause various mutations in the gametes. Such violations may occur due to alcohol drunk a few years ago and affect the ability to fertilize. In a woman who abuses alcohol, the oocyte vitality index is significantly lower compared with a girl who adheres to a healthy lifestyle.
- Smoking. The nicotine in cigarettes clogs blood vessels, disrupting uterine circulation. This leads to a significant deterioration in quality and a decrease in the number of female germ cells. It doesn't matter if you are a smoker - active or passive. The negative effect of cigarettes equally affects health.
- Reception of medical preparations. Some drugs lead to abnormal oocyte development, which shortens their viability. Even if fertilization occurs, the negative effect of drugs can affect the health of the fetus. Hormonal birth control pills cause a lack of ovulation, so a few months before the intended fertilization should refuse to take pills.
Women who dream of becoming pregnant are recommended to increase the quality and longevity of their eggs. This will have to abide by the rules and make a lot of effort and patience.
What to do to increase the viability of oocytes:
- lead a calm, measured lifestyle,
- avoid nervous shocks
- sleep at least 8 hours a day,
- eat healthy and balanced food
- do sport,
- refuse to take hormonal contraceptives,
- consult a gynecologist for the treatment of chronic diseases of the genital organs,
- check with the endocrinologist the work of the endocrine organs, especially the thyroid gland.
When a family fails to conceive a child from the first attempts, it is necessary to determine the onset of ovulation. This is the most favorable time for fertilization: the couple needs to manage to “catch” the coveted day.
Prospective parents take into account the life expectancy of the egg: it is important for the onset of pregnancy. In all women, it is different and depends on the action of factors capable of causing premature cell death. For a successful conception, it is necessary to take into account all the conditions affecting the viability of the egg.
Where does the egg ready for fertilization come from?
In the body of a woman, even in the period of her intrauterine development, the so-called ovarian reserve is laid - a certain number of germ cells, potentially ready for fertilization. They are located in the thickness of the ovaries and are not functionally active until a certain point, in fact, “dozing”. The state of the eggs is determined by a dynamically changing hormonal background.
Initially, primary reproductive cells capable of active division by simple mitosis are laid in the ovarian tissue. Due to this, there is a progressive increase in the number of precursor cells of the eggs. They are called oogony (or ovogony). The process of their reproduction occurs between 2 and 5 months of intrauterine development of the female embryo. During this period, up to 7 million immature germ cells are found in the ovaries of a developing child.
By 6-7 months, ovogonia lose their ability to proliferate, some of them undergo a reverse development and die by apoptosis. The rest enter into meiotic division and stop in development after its 1st stage. The resulting cells are tetraploid, that is, they contain double, but not yet separated, genetic material. They are already called oocytes of the first order. Such cells are located in the primordial ovarian follicles.
The stationary stage of waiting with the meiosis stop will continue until the moment the germ cell is activated. This is possible only with the onset of puberty and the inclusion of endocrine cyclic stimulation of the ovaries. Under the action of hormones, several oocytes are activated and continue to meiotic division. But it usually reaches completion only in one cell. But simultaneous maturation of several oocytes is not excluded, which is a prerequisite for the birth of fraternal twins.
As a result of completed meiosis, a first-order tetraploid oocyte forms an egg cell with a haploid set of chromosomes and 3 reduction bodies. When this occurs, a progressive increase in the dominant follicle in the ovaries occurs. The mature egg ovulates, that is, it leaves the ruptured vesicle beyond the limits of the ovary. From now on, she can be fertilized.
Find out more about the ovulation process in our previous article.
What happens after ovulation
The ovulated oocyte must move to the uterus. After all, only there can a full-fledged implantation of the ovum formed after fertilization. The egg cell itself does not have devices for independent migration, unlike sperm. And in most cases it is transported by the fallopian tube. That is why this organ is also called the oviduct, in its lumen most often occurs the meeting of the egg with sperm.
Scheme of maturation of the egg and its release
The egg migration is provided by several mechanisms:
- the seizure of the ovulated germ cell by actively contracting uterine fringes (villi), which, as it were, envelop one pole of the ovary and “catch” the egg cell,
- peristaltic contractions of the uterine tube wall,
- the cilia of the ciliated epithelium of the fallopian tube, which creates a serous fluid flow directed towards the uterus.
Moving through the fallopian tube is not a quick process. In the case of completed fertilization, the resulting fertilized egg reaches the uterus only 5-7 days after ovulation.
Sometimes the oocyte begins intra-abdominal migration, heading for another fallopian tube. How this is provided is still not reliably elucidated. And in more rare cases, it remains around the ovary.
If the egg is not fertilized, it dies. Its life span can range from 12 to 36 hours, most often it remains viable during the day.
Death and subsequent aseptic lysis of an unclaimed oocyte usually occurs in the distal third of the fallopian tube. At the same time, its remnants after some time fall into the uterine cavity and are displayed together with menstrual secretions. If the death occurred in the abdominal cavity or near the ovary, there is a complete resorption of the egg, without activating the inflammatory response.
Why does an unfertilized egg die?
The short period of independent life of the egg is due to the peculiarities of its structure and functioning. And they are due to the occurred meiotic division.
Meiosis is a special process inherent only to germ cells. It ensures the formation of gametes with a haploid (i.e. half) set of chromosomes. That is, each normally developed oocyte contains only 23 chromosomes, one of which is sexual. Their number is the same in sperm, only his sex chromosome can be X or Y.
It is haploidy and is a key limiting factor. Indeed, for the full synthesis of proteins in humans and mammals requires the presence of both DNA chains. Therefore, gametes with half the number of chromosomes are not able to synthesize the necessary protein molecules. So, the term, how many cells live, is determined by the quantity and quality of previously formed proteins.
At the same time, the cytoplasm of the egg contains many components of the so-called protein synthesis system. These include tRNA, rRNA, mRNA, and ribosomes. But they are auxiliary and can start work only when receiving information about the composition of proteins that require synthesis. And this happens only after the formation of double-stranded DNA, that is, after fertilization and the fusion of the genetic material of the egg and sperm.
So the egg is not capable of long-term independent existence due to the lack of the possibility of protein synthesis. It does not have available, full-fledged reserves and a source of external power, therefore it lives no more than a day after ovulation.
How to clarify how long the egg lives after ovulation
Knowing the exact life of an egg would greatly help spouses planning a pregnancy. But, unfortunately, at the present time there are no available methods that allow reliably and at the same time safely track its position and functional activity.
The structure of the mature egg
Although the egg cell is the largest cell of the human body, its size is not sufficient for reliable in vivo imaging after it leaves the ovary. Moreover, the methods used to diagnose ovulation do not allow to determine whether the oocyte is alive or has already died. After all, the egg does not make active movements. So it is impossible to distinguish between the passive transport of a dead cell and the movement of a still-living oocyte.
What affects the viability of the egg
Very relevant is the question of the influence of various factors on how many days an egg lives after ovulation and how quickly it can be fertilized.
The viability of female gametes is determined by several points:
- how safe and functionally valuable are the genetic material and structural proteins of the egg,
- how many substances she has accumulated in the preovulatory period,
- the individual characteristics of the woman, determining the basic life program of the cells.
But external factors have little effect on how much the oocyte lives. After all, after ovulation, it is not in contact with actively updated biological fluids and other cells, with the exception of serous fluid of the abdominal cavity and fallopian tubes. But the concentration of potentially harmful substances in them in most cases is too low to damage the egg. Moreover, it is not inclined to absorb anything from the outside, being a practically isolated system.
So smoking, alcohol, drugs, chronic occupational intoxication, infectious and inflammatory diseases can only have a predisposing effect. They can adversely affect the oocyte ripening in the ovary, leading to mutations of genetic material and potentially shortening its life span. But these factors can not destroy the gamete already released from the follicle.
Only radiation can have a direct damaging effect if exposure occurred within a day after ovulation.
The main factor that reduces the viability of the eggs and thereby reduces the likelihood of conception, often becomes the age of the woman. This is due to the gradual accumulation of genetic defects in DNA. Although they do not disrupt the process of oocyte maturation, they can lead to a change in the structure of key proteins.
So, after ovulation in 30 years, the oocyte often retains its viability for more than a day. In addition, it separates well from the follicle and migrates freely. But for women in their 40s, ovulation not only occurs not in every cycle, but is not always physiologically complete. It is possible to break the follicle without leaving the egg, as well as the death of the oocyte within a few hours. In combination with the frequently occurring dyshormonal problems and impaired patency of the fallopian tubes, this significantly reduces the likelihood of rapid onset of the expected pregnancy.
The main objective of the egg is the removal of genetic material beyond the ovary, for subsequent fusion with the sperm. In this case, the time interval for the onset of conception is very small and usually does not exceed 1 day. This should be taken into account when planning a pregnancy, because sexual intercourse 24 hours after an accomplished ovulation will no longer be effective.
Life cycle features
To understand the biological process of maturation of the eggs in the female body is very important to touch the basic knowledge of their development. Initially, each woman has a certain number of female germ cells, bestowed on her by nature. Approximately 1-1.5 million follicles are already present in the body of a newborn girl. Immediately after the birth of the girl, her follicles are not active. Maturation will begin much later - during puberty.
The appearance of the first menstrual periods is a signal from the female body that the maturation of the follicles has begun. On average, the first menstruation occurs in girls at the age of 10-13. The time of their appearance is a very individual parameter. In some girls, they may appear first, and much later - by the age of 14-16.
From the moment of menstruation and until their complete cessation with the onset of menopause, a woman is reproductive, that is, capable of having children. This period is called the time of reproduction. In the reproductive woman's body, the eggs mature each month. This process takes place continuously. It is conceived by nature so that a woman can become a mother in a natural way and continue the race.
The entire menstrual cycle of a woman can be divided into several successively successive phases:
- Menstruation. The first day of your period is the first day of the new menstrual cycle. The previous day before the month ends the previous menstrual cycle. The time interval between menstruation in each month and determines the total duration of the menstrual cycle. According to statistics, it is on average 28-30 calendar days.
- Follicular. Characterized by egg maturation. Lasts immediately until the rupture of the follicle.
- Ovulation. It is usually in the middle of the menstrual cycle. On this day, the dominant follicle bursts, and the mature egg leaves into the abdominal cavity.
- Luteal. Begins after the release of the egg from the follicle. In place of a bursting follicle in the female body, a special formation appears - a yellow body that produces progesterone. If the egg remains unfertilized, then the corpus luteum is subsequently reduced.
Female genital cell life expectancy
Ovulation is a very important day of the menstrual cycle from a biological point of view. All hormonal processes occurring in the female body throughout the entire menstrual cycle are largely necessary only for the egg to fully mature and to be prepared for a meeting with the sperm cell.
With a 28-day menstrual cycle, the day of ovulation usually falls on the 13-14 day. Unfortunately, it is not always possible to correctly determine the final maturation of an egg by a simple calendar counting method.
Special pharmacy tests, folliculometry, as well as measurement of basal body temperature, help to determine ovulation more accurately.
A couple of days before the onset of ovulation, the dominant follicle, in which the maturation of the egg occurs, increases. Usually by this time its dimensions are 18-20 mm.
In order for the dominant follicle to burst, hormones are needed. The follicle growth during the follicular phase of the menstrual cycle is influenced by FSH - follicle-stimulating hormone. It acts in such a way that the dominant follicle grows approximately 2 mm each day.
The day before ovulation, the concentration of luteinizing hormone (LH) rises rapidly in the blood. Under his influence, the dominant follicle ruptures and the mature egg cell leaves it.
The female reproductive cell first enters the abdominal cavity, and then “absorbed” by the villi of the fallopian tube. It should be noted that the egg practically does not carry out independent movement, in contrast to the spermatozoon. It moves through the fallopian tube due to the special peristalsis of its wall. The movement of the egg through the fallopian tube can not be called fast.
If the merging of germ cells has happened, then a new biological element is formed - a zygote. It is a fertilized egg, whose cells begin to actively divide. Subsequently, a small embryo is formed from the zygote, which is attached to the inner wall of the uterus. From the moment of fertilization and pregnancy begins.
It also happens that in the female body several eggs mature. In this case, during ovulation, both of them can come out of the ovaries. This situation increases the likelihood of conceiving twins or twins.
After ovulation, the egg remains viable, usually within 12-24 hours. If the female reproductive cell did not meet with the sperm and fertilization did not occur, then she dies. In a woman's body, the next phase of the menstrual cycle begins.
Causes of death
Scientists have found that in most cases the unfertilized germ cell dies while in the distal part of the fallopian tube. The remains of the dead egg will be removed from the body during the next menstruation.
Much less often, the death of an unfertilized egg occurs directly in the abdominal cavity. As a rule, this contributes to any pathology of the fallopian tube. The presence of adhesions or congenital anomalies of the fallopian tubes can become obstacles to the physiological movement of the egg, and hence to the onset of pregnancy.
It is conceived by nature that an unfertilized egg cell dies. This is due to its special structure. The egg cell has only a haploid (half) set of chromosomes. Such a set of "includes" 22 normal and 1 sex chromosome. With such a half set, a cell cannot fully exist. Synthesis of proteins essential for the activity of the germ cell is possible only with diploid set of chromosomes.
Unfortunately, in practice, eggs do not always mature every month. Even a healthy woman can have menstrual cycles when ovulation does not occur. They are called anovulatory.
Such cycles develop for many reasons.
If anovulatory menstrual cycles are repeated in a woman too often, then this is already a consequence of the presence of pathology. In such a situation, it is necessary to establish the cause, which contributes to the violation of ovulation. Frequent anovulatory cycles can cause infertility.
There are also clinical situations when the date of ovulation is shifting. As a rule, they develop due to the presence of any gynecological or endocrine pathologies in a woman. In this case, the follicle usually develops slowly, but on the expected date of ovulation it does not open.
Insufficient levels of LH can also affect the opening of the follicle. An unopened follicle in the future may simply decrease in size or, over time, turn into a follicular cyst.
Factors affecting vitality
For quite a long time, scientists tried to establish on what factors the viability of the egg after ovulation depends. This knowledge is necessary in order to understand how to plan pregnancy for couples who have difficulties with the natural conception of the baby.
Investigating the stages of development and maturation of female germ cells, scientists concluded that the following factors affect their viability:
- safety and functional suitability of genetic material contained in chromosomes,
- the amount of protein particles inside the cytoplasm of the egg, accumulated during the pre-ovulatory period,
- individual characteristics of the female body.
Experts note that the more viable are younger eggs. It is believed that the chance to conceive a child in 40 years is much lower than in 25. Such a decrease in fertility with age is due to numerous factors. Psychoemotional stresses, unhealthy lifestyles and bad habits, concomitant diseases, hormonal disruptions, the effects of miscarriages and abortions and many other causes have a negative impact on the maturation and development of the eggs.
Научно доказано, что на жизнеспособность яйцеклеток отрицательное воздействие оказывает и ионизирующее излучение. Радиация при этом оказывает самое неблагоприятное воздействие, приводя к быстрой гибели половых клеток.
Ученые считают, что в более молодом возрасте яйцеклетка способна сохранять свою жизнеспособность в течение 36 часов. После 30 лет это время уже сокращается до 12-24 часов. In women after forty years, even when ovulation is preserved, the life of the egg is significantly lower and can even be 4-6 hours. If at the same time the woman has any related gynecological diseases, then the chance of natural conception decreases many times.
Terms of viability of ovules after ovulation help many couples to plan the conception of the baby. Knowing the exact date of ovulation, you can purposefully plan fertilization. Experts recommend on the day of ovulation to perform several sexual acts. This will increase the likelihood of possible fertilization.
It is important to remember that the egg after leaving the follicle may remain viable throughout the day. If the sperm are healthy and active, then at this time the chances of conceiving a baby increase dramatically. Healthy sperm can persist in the female genital tract for several days. At this time, the risk of conception is also quite high.
Some women in order to provoke ovulation in them, resort to taking special medicines that stimulate the ovaries. Doctors do not recommend it themselves. It is extremely dangerous to resort to the reception of such funds for women with gynecological diseases or dishormonal disorders. Any prescription of drugs that stimulate ovulation should be done only by a gynecologist.
In order to increase the potential viability of the eggs, it is very important for the woman to look after her health. Maintaining a healthy lifestyle, eliminating bad habits, a normal 8-hour sleep and a balanced diet are the basis for maintaining fertility for many years.
In the event of adverse symptoms on the part of the genitals, it is not necessary to postpone a visit to the gynecologist for a long time. Early treatment of gynecological diseases in the early stages will help to maintain reproductive health in the future.
How to set the time of the upcoming ovulation?
With the help of the test, the level of hormone in the urine is fixed. An increased figure indicates the impending exit of the egg, which will occur in a day. The test is performed similarly to a pregnancy test.
The period of how much an egg lives after ovulation for each woman is different and depends on the state of health of the body, the reproductive system and other factors. It also determines whether a full-fledged healthy embryo is produced from an egg or not.
The period of maturation of the egg - the preovulatory phase is characterized by changes in the female body associated with its preparation for conception. There is a softening of the walls of the cervix and its opening for the unimpeded movement of spermatozoa, a change in the mucous membrane of the uterus, ready to “take” the future embryo, etc.
It should be noted that all these internal changes in the body of a woman have a beneficial effect on her condition and appearance. The woman is in a great mood, the skin becomes smooth, gets velvety and she becomes very sexy and attractive to the opposite sex.
After maturation of the egg and exit into the abdominal cavity, it enters the fallopian tube, where the meeting with the sperm and the expected fertilization should occur. The life of the egg lasts only 12 hours, during which it has the ability to fertilize. Within a day, the mature and unfertilized female reproductive cell will die.
The most favorable time for conceiving a child is considered the first day after ovulation.
Why do couples need information about how much an egg lives after ovulation?
These data are of great importance for planning the conception of a baby. With regular regular sex with her partner, a woman, as a rule, can become pregnant within six months. And the most favorable period and the necessary conditions for conception, namely the period of ovulation. If the couple does not plan to replenish their family, then strict adherence to the rules of protection in these days will help avoid unwanted pregnancy.
Ripened egg, getting into the fallopian tube, is in the stage of waiting for a meeting with the sperm. Therefore, a woman has a chance to become pregnant only once in the entire female cycle - one day in the middle of the cycle. Unlike the egg cell, the sperm cell can be in the fallopian tubes or in the uterus, waiting for ovulation for several days, while maintaining its fertility.
If conception did not happen, the unfertilized egg, together with the epithelium of the uterus walls and blood, is rejected and removed from the uterus in the form of menstrual flow. After this, the process of renewal of the epithelium and maturation of the next egg in the ovaries occurs. This forms the menstrual cycle. A woman’s lack of ovulation is an indicator of deviations and disorders in her health and body.
But even in the case of the correct determination of the days of ovulation, a short egg lifetime after ovulation greatly reduces the chance of becoming pregnant. It should also be borne in mind that in different months this day may shift, “float” simultaneously with the shift of the menstrual cycle. Therefore, taking into account the fact that the egg's life time after ovulation is short, a long-awaited event of conception, some couples have to wait six months or longer. To speed up this process, it is recommended that throughout the whole cycle permanent unprotected sex every other day, and especially during the period of supposed ovulation.
Considering the lifetime of an egg after ovulation, the greatest chance of becoming pregnant occurs during intercourse no earlier than three days before ovulation or the day after. Then begins the process of regression of the egg and the development of the next stage of its life.
If another attempt to get pregnant did not work, this is not a reason for frustration. One should enjoy and enjoy unprotected sex, anticipating future motherhood and rejoicing in the presence of a loved and caring man nearby. And also it is necessary to refuse alcohol and smoking - the worst enemies of the ripening eggs.
What is an egg cell?
The girl receives the set of cells necessary for reproduction even during the period of intrauterine development and loses half of its quantity before reaching puberty. After 30 years, the number of fertilizable eggs in the female body gradually decreases. This phenomenon is called "biological clock", which under its own power reduces the possibility of a woman getting pregnant.
How long does an egg live in the body and what affects its viability?
The following external and internal factors can affect these deadlines:
- Stress. A delay or too early onset of menstruation, late ovulation or its absence in the cycle is most often provoked by the stresses experienced by the woman.
- Hormonal background. The lack of a number of hormones, including progesterone, is the reason that the dominant does not mature. Problems with hormones are the main cause of primary female infertility.
- Instincts. Sometimes, when a woman wants to get pregnant too much, ovulation can occur again, even at the end of the cycle.
- Disease. Most infectious and viral diseases that are sexually transmitted, pathologies of the development of internal and external genital organs, cystitis, problems with the gastrointestinal tract and liver affect the female cycle and can delay the onset of ovulation.
Unlike ova, male spermatozoa are more viable cells, the duration of activity can last from 4 to 7 days. From the vagina into the uterine cavity, and from there into the fallopian tubes, the spermatozoa "reach" in 2-3 days. In one hour they cover a distance of 1 cm.
How to determine the maturation of the egg: symptoms during ovulation
Many women, on their own well-being and inner feelings, anticipate the onset of ovulation. Signs indicating that ovulation will occur in 1-2 days include:
- Breast engorgement. Appearing breast sensitivity is considered by many to be signs of an approaching menstruation. For many women, on the contrary, their breasts slightly increase in size and it hurts just before ovulation. This process is caused by excessive production of a certain hormone and the reaction of the organism to it.
- Highlight. Before ovulation, vaginal secretions change their appearance and texture. If the follicle has matured and burst, the discharge from the cervical canal will increase slightly in volume and will resemble mucus in consistency. If the loop is anovulatory, the discharge will have a creamy texture with a beige tint.
- Abdominal pain. Sometimes in the place where the ovary that has released the egg is located, there may be unpleasant pulling sensations. After ovulation occurs, the pain disappears.
- Temperature rise. A sure sign of an approaching ovulation is an increase in basal temperature. Many women use temperature measurements in the anus as a way to prevent or, on the contrary, pregnancy. However, in order to build a graph of basal temperature, daily observations must be carried out over several months.
- Sexual attraction. The increased desire for reproduction in the days of ovulation was noticed by women since the times of primitive people who lived, focusing only on their instincts.
- Other manifestations. Many women note that before ovulation, as well as before menstruation, they have a headache, their general condition worsens, drowsiness increases and fatigue appears.
When does conception occur?
How to be women who do not experience any sensations before ovulation and do not know when it occurs? In such cases, you can resort to reliable methods for determining favorable periods for conception:
- Tests Luteinizing hormone-sensitive ovulation tests have proven to be one of the most accurate methods for determining conception-friendly days. They work on the principle of pregnancy tests. Test strips are placed in a container with urine and wait for the result to show. Depending on what stage of maturation is the follicle, the strip located on the test will change its tone - from light to dark color. The light band indicates immaturity of the follicle, dark - that the release of the egg will occur in the next 24 hours. If tests are done after ovulation, they will again show bright stripes indicating that the cell is dying, and the concentration of the hormone necessary for its life is gradually decreasing.
- Ultrasound. Ultrasound, aimed at determining the presence of ovulation, is called folliculometry. They do it several times in one monthly cycle with a break of 2-3 days. Most often, folliculometry is prescribed to women undergoing a comprehensive pre-pregnancy examination or faced with the problem of primary infertility to determine its cause. Ultrasounds are performed on days 7, 10, 13, and 15 of the cycle, which show the stages of development of the dominant follicle. Folliculometry is one of the most accurate ways to determine ovulation, but to conduct it you must visit the medical institution on each of the days determined by the gynecologist.
- Inspection. When conducting a gynecological examination, the doctor can see that the cervix has softened and raised a little, thus creating optimal conditions for sperm to penetrate deep into the cervical canal. The channel itself these days slightly opens up and resembles the pupil in appearance.
Knowing how many hours of life is allotted to the female germ cell after it leaves the ovary, you can podgadat the most successful time for conception. To calculate favorable days, you need to rely on the duration of the menstrual cycle. On average, it is 28 days and ovulation in this cycle occurs on day 14. "Dangerous", that is, the most suitable days for fertilization, when the follicle will burst, is considered the period from 12th to 15th day of the cycle.
Since the egg cell does not live very long, and the sperm may take several days to reach their goal, sexual intercourse is best done 1–2 days before ovulation. However, to deplete sperm daily sexual contact is not worth it. Sexual intercourse several times a week before ovulation may result in the onset of a long-awaited pregnancy.
What happens before ovulation
Ovulation of the egg in women without health problems, whose cycle is normal, is observed about 14 days after the start of menstruation. During this period, maturation of the egg in the ovarian follicle should occur. Most spouses planning replenishment in the family often come up against the question of how much an egg lives after ovulation. It is the lifetime of the egg has a direct impact on the successful conception of the offspring.
In the body of a woman, long before ovulation, several ovules are observed maturing in the follicles - special areas of the ovarian tissue. It should be noted that the correct process of the work of the internal organs of the reproductive system is possible only due to the synchronous activity of the endocrine and nervous system.
At the first stage of the menstrual cycle, the main follicle is aging. Further, an egg-bearing tubercle appears, which is part of the wall of the tertiary follicle, where the formation of an oocyte of the first order occurs. In certain cases, their number can be equal to two, and sometimes there are even more.
It should be noted: how many eggs will mature, presumably as many embryos will be formed. It is the simultaneous maturation of several eggs that makes multiple pregnancy possible.
The follicle before the onset of ovulation must reach a certain volume and only then the egg leaves it. As a rule, by the 14th day of the cycle it grows up to 2000 mm, and then, every subsequent day, grows by another 2-3 mm.
The menstrual cycle before the onset of ovulation is associated with such characteristic changes:
- increased secretion and change their consistency,
- increase in the synthesis of luteinizing hormone,
- soreness in the lower abdomen and chest area,
- softening of the cervix,
- increased libido.
These symptoms are often seen in most women with ovulation. But it is precisely systematic ovulation indicates excellent health. That is why, in the absence of menstruation at the lady, as well as during long unsuccessful attempts to conceive a child, the couple should visit a specialist, who will help identify the cause of infertility. However, it must be borne in mind that the cycle during the year often includes a couple of anovulatory phases, when a woman does not have an egg release from the follicle.
Processes for ovulation
The life span of an egg after ovulation has a direct impact on a woman’s ability to conceive a child. As a rule, ovulation occurs once in a cycle, and any fluctuations are often triggered by hormonal disorders.
By the middle of the cycle, egg maturation is observed. Coming out of the follicle, due to its rupture, it contributes to the appearance of certain symptoms in women:
- there is an increase in blood flow in the region of the internal organs of the reproductive system,
- significant increase in cervical mucus production,
- softens the cervix, in order to facilitate the movement of sperm,
- progesterone production is increasing,
- basal temperature increases.
In other words, the body prepares the optimal environment for fertilization. At the same time, the size of the follicle with ovulation reaches 18-25 mm. Having reached such impressive volumes, it bursts, releasing a mature egg. In certain circumstances, the ripe follicle does not burst and ovulation, of course, is not observed. In this situation, the follicle gradually decreases in size and disappears or it continues to exist in this form, but this is fraught with the formation of a follicular cyst.
However, what happens to the egg after ovulation? With the opening of the follicle, the matured egg begins to move through the fallopian tube, where spermatozoa are waiting for it. When fertilization occurs, the embryo begins to develop, a zygote is formed. In the case of his absence, the viability of the egg is lost, and she leaves the body of the woman with the endometrium layer rejected as unnecessary.
It is important to remember that the lifetime of an egg after ovulation is short. Therefore, a couple who wants to conceive a baby must be seriously prepared for ovulation. To identify the approaching ovulation can be using the calendar method and tracking the signs of the phenomenon or you can resort to using specialized test or ultrasound. The latter methods are more reliable, but if even with their help they fail to conceive a child, then you need to resort to the help of a doctor.
Egg life term
A considerable number of women are interested in the question: how long does an egg cell live after ovulation? Often, after she leaves the follicle, her life cycle lasts 12-24 hours. In certain circumstances, she can live longer, but the egg cell's lifespan is related to the specificity of each body and the actions of environmental factors.
Женщине, которая страстно желает стать мамой, необходимо следить за овуляцией. А так как сколько живет яйцеклетка после овуляции уже известно, и это весьма непродолжительный период, то необходимо чтобы половой акт произошёл до её высвобождения из фолликула. Of course, the sperm are in the fallopian tubes a few minutes after sex, but in order to successfully fertilize the egg they need to ripen. Often, for this they need 6-12 hours.
In addition, ovulation takes place at different times. The follicle may burst a day or two earlier or later. That is why couples need to know for sure when there will be ovulation, how much the egg cell lives after it, and in addition, it is necessary to understand the processes that take place in the body of a woman in such a difficult time. In other words, the life cycle of an egg is not the main significant factor for spouses who want to become parents.
However, if a couple has difficulty conceiving, the doctor performs an ultrasound scan in order to identify the exact size of the dominant follicle. When its growth is not observed, the doctor prescribes hormonal agents that promote ovulation. It’s better for future parents to know that for successful conception, intercourse can occur several days before ovulation, but after it this probability decreases.
How to contribute to conception? Param it is important to adhere to such rules:
- monitor the size of the follicle by ultrasound and determine ovulation due to the test,
- start intercourse 7 days before ovulation,
- better if the couple has sex every other day,
- systematically consult a doctor who will monitor the success of the process.
If you follow these rules and understand all the subtleties of the events, then this period will bring a lot of pleasant emotions and pregnancy will not take long. And then the pair will begin another, equally saturated with pleasant emotions period.
