Many women who want to give birth to a baby are familiar with the feeling of trepidation and anticipation of the moment when they can take a pregnancy test and make sure that fertilization has occurred. At negative results spouses experience disappointment and begin to wonder if they are infertile. Conceiving a child the first time is not as easy as it seems, so you shouldn’t give up after the first failure and stop trying. What factors can contribute to rapid conception, increase the chances of conception, and what to do when you can’t get pregnant?

What factors influence conception after the first time?

Is it possible to get pregnant the first time? In order for fertilization to occur as a result of sexual intercourse, a number of factors must coincide:

1. Fertility window. There are several days in the menstrual cycle when a girl is able to conceive; at other times this will not happen. Ovulation is the release of a mature egg from the ovary; it occurs approximately in the middle of the cycle. It is at this moment that the male and female reproductive cells can merge and form an embryo. If you have sexual intercourse when the egg is not yet mature or has already left the fallopian tube into the uterus, fusion will not occur.
2. Sperm viability. To enter the fallopian tube, sperm must overcome several obstacles such as acidic environment vagina, cervical mucus, reach the fallopian tube and wait until the egg is released. Inactive spermatozoa with structural pathologies will not be able to overcome this path. Male reproductive cells live for 2-3 days, in some cases up to 5 days, and then die.
3. The health status of the spouses and their age. Past diseases affect sperm quality and condition reproductive organs. Inflammatory processes, sexually transmitted infections - all this can affect the fertility of partners.

What is the probability of getting pregnant the first time? How younger woman, the higher the likelihood that after the first sexual intercourse without contraception she will conceive. If spouses want to quickly become parents, then they should start trying at the age of 20-25 years.

What are the chances of a couple getting pregnant if they don't use contraception?

According to statistics, fertilization occurs the first time in every 6 women. This high performance, considering how many factors must coincide for this to happen.

If you are unable to get pregnant right away, you should not despair. Spouses should continue to have intensive sex life and, as studies show, 60% will be able to conceive within six months.

A couple is considered infertile when a woman fails to become pregnant after one year of regular sex at least 2 times a week. However, in this case there is no need to despair, modern medicine successfully copes with most causes of infertility.

Why is it not always easy to get pregnant without protection? The reasons may lie in diseases of the reproductive system.

How to conceive a child quickly?

How to conceive a child the first time? For those couples who do not want to postpone the birth of a baby, there is special methods, promoting fertilization. Some of them have scientific explanation, which is based on the characteristics of the reproductive sphere of men and women, other methods are based on folk beliefs and ideas, however, none of them gives a 100% guarantee; all these methods only increase the chances.

Medical examinations

Before having a child, some couples want to be examined and find out if they have diseases that prevent conception. This is a reasonable approach that allows you to immediately identify the reasons why pregnancy does not occur and treat diseases that may affect the course of pregnancy in the future.

Examinations that a woman undergoes:

• diagnosis of tubal patency - obstruction of the fallopian tubes is a consequence of salpingitis, ectopic pregnancy, inflammatory process;
• hormone analysis - polycystic ovary syndrome, pathologies of the hypothalamus, pituitary gland, thyroid gland may cause infertility;
• hysteroscopy - examination of the uterine cavity;
• folliculometry - monitoring of folliculogenesis;
• postcoital test - shows the immunological incompatibility of the couple due to the production of antisperm antibodies.

Both spouses should be tested for STDs. Often it is venereal diseases become an obstacle to the birth of a baby. A man separately takes a spermogram, which checks the quality of sperm: the activity and motility of sperm, their structure. At male infertility the problem is often insufficient quantities sperm in semen, their immobility or pathological structure.

Calculating the favorable period for conception

The only time a woman is able to conceive is during her fertile window. This is the name for the period that begins a few days before ovulation and ends one day after it. To calculate the favorable period for sexual intercourse, you need to know when ovulation occurs.

The egg matures 14 days before the start of the next menstruation. When a woman has a regular 27-day cycle, ovulation occurs exactly in the middle - on the 13th day. Considering the lifespan of sperm, the window of fertility in this case falls on days 8-14 of the cycle.

Is it possible to get pregnant if you have a short or long cycle? Let's say monthly cycle lasts 23 days. Thus, ovulation will occur on day 9, and the fertile window will be from days 4 to 10. With a cycle of 34 days, the egg matures on the 20th day, and you can get pregnant between 15 and 21 days. What is the probability of getting pregnant on the day of ovulation? There is no one hundred percent certainty, but if you time it correctly, the probability of conception is very high.

Popular beliefs say that depending on the date of conception, you can accurately plan the gender of the child. If a sperm fertilizes an egg on the day of ovulation, a girl will be born. Having sexual intercourse before ovulation will help give birth to a boy.

Not every woman can boast regular cycle. It depends on the state of health, stress, nutrition, climate change, individual characteristics body. How do you know if an egg is ripe? There are several ways to do this:

1. Measuring basal temperature. Every day for several months, a woman should measure her temperature immediately after waking up, and record the results in a notebook. As soon as the value on the thermometer increases by 2-3 tenths of a degree, you can have sex, ovulation has occurred.
2. Ovulation test. Test strips are sold in pharmacies and act on the principle of a pregnancy test. Markers react to change hormonal levels women at the moment of maturation of germ cells.
3. Ultrasound examination. An ultrasound can determine when the follicle is ready to rupture and release germ cells.

Choosing a position for conception

There is an opinion that certain positions during sex affect the ability to conceive. It is believed that the deeper the penetration, the easier it will be for sperm to overcome obstacles and exit into the fallopian tubes. That is why adherents of this theory consider the most successful position in which a woman stands on all fours or lies on her back with her legs raised high, placing a pillow under her buttocks. Some believe that positions during sex affect the gender of the child. For example, when a woman is positioned below, there is a high probability of giving birth to a girl.

The cowgirl position is considered unsuccessful because the woman is on top and sperm may leak out of the vagina. To prevent this from happening, it is recommended not to get up immediately after sexual intercourse, but to lie down for a while, preferably raising your legs to the “birch” position. It is also believed that the likelihood of fertilization increases when a woman has an orgasm. Contractions in the uterus and vagina will help push the sperm inside.

Most doctors believe that posture has no effect on the likelihood of conception. However, in some cases, position during sex can contribute to pregnancy. With such a pathology as a bent uterus, it is advisable to have sex on the side in which there is a bent.

Nutrition and lifestyle of men and women

Successful conception largely depends on the lifestyle of the spouses. Poor nutrition, excess fatty and fried foods, drinking alcohol and drugs, smoking, sedentary sedentary image life, promiscuity, constant hypothermia or overheating - all this affects the fertility of men and women.

Some foods have a positive effect on sperm quality. A man should regularly eat:

• parsley;
• celery;
• fermented milk products;
• nuts;
• bananas;
• pineapples.

A woman should start taking 2-3 months before her expected pregnancy. folic acid. This vitamin will not harm men either; in addition, at the pharmacy you can buy drugs to improve the quality of sperm “Spermaktin” and “SpermActiv”.

A year before planning a child, the couple should give up smoking and alcohol. This will improve the health of the body and minimize the risks of abnormalities in the unborn child.

Folk remedies

How did our great-grandmothers treat infertility? For quick conception women used decoctions medicinal herbs. Several folk recipes for quick pregnancy:

1. Decoction of boron uterus. 4 tablespoons of dry herb pour into 1 liter hot water and leave for 2 hours. When the decoction is infused, it should be strained and taken 1 tablespoon three times a day before meals.
2. Sage decoction. 2 tablespoons of the herb are poured into 0.5 liters of boiling water and placed in a dark place for 2-3 hours. After this, the broth is filtered and taken 1 tablespoon every day until menstruation occurs or the woman is sure of pregnancy. If menstruation has begun, then you should stop taking sage and resume treatment after a month. Dry sage can be bought in pharmacies.

Not all folk recipes based on reception medicinal herbs. Some of them are dangerous to health, and a woman should never use them. For example, it is believed that douching with soda will help reduce the acidity of the vagina and sperm will be able to penetrate inside more easily. alkaline environment. This method will not only not help you get pregnant, but will also cause burns and irritation of the mucous membrane.

Issues of pregnancy and conception concern any couple who have sexual intercourse - of course, if this couple does not belong, as they say today, to sexual minorities. Some are trying their best to avoid unwanted pregnancy and the difficulties associated with this, while someone carefully calculates the days of the cycle and plans intimacy on those days when the likelihood of getting pregnant is highest. On what days is the likelihood of conception the greatest, and on what days of the cycle is pregnancy unlikely?

The female menstrual cycle can be divided into three periods, the duration of each of which is calculated individually for each woman. On average, the first 14-16 days, counting from the first day last menstrual period, occurs during the maturation of the egg. On days 14-16, the mature egg is released into the fallopian tube, where it can meet the sperm. From about 15-17 until the end menstrual cycle The so-called corpus luteum phase lasts, when in place of the follicle from which the egg emerged, corpus luteum, and the uterine mucosa is preparing for possible reception embryo. If pregnancy does not occur, this mucous membrane is rejected - menstruation occurs.

The greatest chance of getting pregnant for most women occurs from the 14th to the 16th day of menstruation. It is greatest on the day of ovulation, when the egg is in fallopian tube. The probability of conception is somewhat lower within 6 days before ovulation - it exists because sperm can remain viable in a woman’s body for 2-6 days, and fertilize the egg on the day of ovulation. The lowest probability of conception occurs during menstruation, as well as immediately after its end. IN general view, the first 14-16 days of the cycle can be considered safe, but the risk of conception increases as the day of ovulation approaches. The period after ovulation, that is, from the 16th-18th day of the cycle until its end, can also be considered safe.

The so-called method is based on the method of determining the time of ovulation scheduling, which is used both to calculate the most favorable days for conception and plan the onset of the desired pregnancy, and to avoid unwanted conception. However, this method is very conditional, since, firstly, the duration of each woman’s cycle can be different and differ from the standard 28 days. This means that the time of ovulation may occur earlier or later than days 14-16 of the cycle. In addition, not all women have a regular cycle, which does not make it possible to calculate the time of ovulation with a sufficient degree of probability.

Those women who want to calculate the probability of becoming pregnant in order to conceive a child can be advised, firstly, to quit smoking, since the entry of nicotine into the body interferes with the normal maturation of the follicle, and also to stop drinking alcohol, which prevents sufficient release of progesterone.

If you have decided to take the important step of becoming parents, this article is just for you. In it we will try to tell you how to calculate best time when you are most likely to get pregnant, how to increase the likelihood of conception.

What is the probability of conception

The period in the menstrual cycle when the probability of fertilization of an egg is greatest is called the fertile period. Its duration is 48 hours after ovulation. It is important to consider that sperm viability remains for 5 days. Therefore, if we take into account male and female factors, the duration of the fertile period ranges from 6 to 8 days.

To calculate the favorable period as accurately as possible, you need to determine the beginning of ovulation. To do this, several cycles in a row are measured basal temperature. In addition, a variety of tests are used. IN ideal conditions Ovulation occurs monthly approximately in the middle of the cycle. The most suitable fertile period is between 10 and 18 days of the cycle (taking the beginning of menstruation as the first day). If for a long time If you can't get pregnant, make an appointment with a gynecologist.

Calendar for determining ovulation

The main condition is that a woman must know their duration during several menstrual cycles. It is necessary to record the beginning of menstruation on the calendar for six months. For this method, you can use a regular pocket calendar. The calculation is made using the formula:

X - start favorable period for conception

Y - duration of the shortest cycle

Z - end of favorable period

U - duration of the longest cycle

Gynecologists recommend that every girl keep a menstrual cycle calendar, regardless of whether she is ready to become a mother or not. The calendar can be thrown into your purse, it does not take up much space. The calculation is simple, the main thing is not to forget to enter the data into the calendar. Modern smartphones have a calendar in which it is convenient to enter data, and most importantly, always at hand. The only negative is that the ovulation calendar does not allow you to determine the sex of the child.

Chances of getting pregnant before your period

There is a theory that in the few days before your period, the likelihood of getting pregnant is low. Doctors do not have a clear opinion. But we are convinced that getting pregnant before your period is really possible. The menstrual cycle may fluctuate and ovulation may begin later due to certain factors. Therefore, the day when your period is due may shift.

You can get pregnant during your fertile period. In the middle of your cycle before your period, you may feel painful sensations in the stomach, body temperature rises slightly, mood changes. When you notice these signs in yourself, this is the period when conception will be successful.

To better understand whether it is possible to get pregnant before your period, here are a few facts:

• the vital activity of sperm in some cases can reach a week
• During menstruation, a woman can produce more than one egg
• Menstruation does not always come at the same time; due to cycle changes, the time of ovulation changes

Therefore, conception is quite possible 3-4 days before menstruation. Most often, young girls with an unsettled menstrual cycle are at risk. But for adult women, it is also possible to become pregnant before menstruation. So decide for yourself. To take risks or not.

How to increase your chances of conceiving

Previously, it was believed that in order to increase the percentage of conception, a man should abstain from sexual intercourse for several days before the planned act of conception. There is some truth in this statement. Indeed, in the course of research it was found that the frequency of ejaculation in men is interconnected with the amount of seminal fluid secreted. The more often ejaculation occurs, the less seminal fluid is released.

At the same time, there is a pattern in the frequency of sexual intercourse and the fertilizing properties of seminal fluid. Sperm are more mobile in a man who ejaculates more often. This doesn't mean you have to have sex every day. Studies have found that spouses who have sex:

• every day - the conception rate is 25%
• every other day - the percentage is 22%
• once a week - the percentage is reduced to 10%

When making love once a week, the conception rate is lower due to the fact that couples may miss the very moment when it occurs. highest probability successful conception. The optimal rhythm of sexual intercourse is at least 4 times a week

The best positions for conception

Here are some tips on how to increase the likelihood of conception using sex positions.

1. After the end of sexual intercourse, lie down on your side for a while. You can remember your physical education lessons and take the “birch tree” pose. There is no need to imagine yourself as a gymnast and pull your toes up. The purpose of the position is to prevent sperm from leaking out.
2. The structure of the uterus influences the desired position. If the uterus has an internal bend, best pose- lying on your stomach, bending in the direction of the bend. With a bicornuate structure, it is recommended to raise the pelvis upward.
3. It is important to observe the rules of hygiene after the end of sexual intercourse. Most experts are unanimous in their opinion that hygiene products that change the pH value of the vagina should be abandoned.

Probability of conceiving a boy

When conceiving a male child, Y sperm are involved. They are smaller and more mobile, but their lifespan is short. Therefore, if an attempt to get pregnant was made a couple of days before ovulation, Y-sperm will already die by the time it occurs. If the act occurs directly on the day of ovulation or after its end, Y-sperm, due to their mobility, will reach female egg. This is the best time to conceive a boy.

The accuracy of this method is great. The main thing is to correctly calculate the date on which ovulation occurs. In addition to all of the above, experts recommend abstaining from sexual intercourse several days before its onset. It is better for a man to choose a position behind a woman, for deeper insertion of the penis into the vagina.

How to use tables

((banner2-left))How can a table help in conceiving a child? Let's try to figure it out.

1. Japanese table. The calculations in such a table are simple. Below are two tables. The first indicates the months in which both spouses were born. At the intersection of the couple's months, you get your family number. In the second table, by finding the family figure, you can determine when the percentage of male or female births is higher.
2. Chinese table. Has been used since the days Ancient China. Therefore, I absorbed many years of observations. The gender of the child is calculated as follows. In the left column we find the age of the expectant mother. In China, age is counted from the moment of conception. So don't forget to add a year to your age. In the top line, select the desired month of conception. At the intersection we get a letter indicating the gender of the child (M-boy, D-girl).

When is the high percentage of conceiving twins?

The likelihood of conceiving twins depends on the length of your menstrual cycle. Here are a few more factors that increase the likelihood of conceiving twins:

• breastfeeding during conception
• increase in probability after 30 years
• increased chances after the birth of a second child
• the likelihood of twins increases in the spring when the days get longer
• in women whose cycle is from 21 to 22 days
• ethnic factor, African-American women are more likely to have twins
• after taking medications containing hormones
• if there were already twins in the family, especially on the maternal side

• Boys are less likely to be born into families in which both parents smoke.
• The likelihood of conceiving a girl is higher in women whose weight is less than 54 kilograms.
• If the leadership in a family belongs to the father, sons are born more often.
• If the father is older than the mother, the chances of having a boy increase.
• There is a theory that states that the longer a woman tries to conceive, the more likely she is to have a son. To support the theory, often after a couple has undergone infertility treatment, the first-born is a boy.
• After stressful situations More often girls are born.
• Dream about your desired gender of the child. Thoughts materialize.

Conceiving a baby is possible only during the period when a mature egg leaves the ovary and waits for its fusion with a sperm. Women who want to get pregnant look forward to “that very day,” while others, on the contrary, abstain from sexual intercourse at this time. But, if the day of expected conception is determined incorrectly or is missed, is pregnancy possible, and how long does the woman still have maximum fertility?

Fertilization – process of fusion of a mature egg with sperm, which results in the formation of a zygote that carries the genetic information of both parents.

Accordingly, conception occurs when there is a mature woman in the body, which develops in the ovarian follicle from 10 to 18 days.

After this period, it emerges from the cavity of the ruptured follicle, ready for fertilization. The process of releasing a mature egg is called ovulation.

For reference: The timing of follicle maturation is individual and depends on the duration of the menstrual cycle. In 80% of women with a 28-day cycle, the egg is released on the 14th day.

Main features

How many days after ovulation can you get pregnant?

Probability of successful conception determined by two factors: the presence of fertile, viable sperm in a man and a mature egg in a woman.

Because sperm remain viable for up to a week, conception is possible through sexual intercourse that occurred 7 days before the release of the finished egg, and within 2 days after it.

The most successful period for fertilization are the day of ovulation, the day before and after it. At this time, changes occur in the woman’s body that favor the passage of sperm into the body: the consistency of the cervical mucus decreases and the elasticity of the vaginal walls increases.

On what days of the cycle is it possible?

Lifespan of a mature egg lasts up to 24 hours Accordingly, the process of fertilization itself takes place within 24 hours. However, this does not mean that it should happen on this day.

Sperm fertility can last up to 5 days, and, according to some researchers, up to a week. Therefore, sexual intercourse even a week before expected ovulation may well result in conception.

Based on these data, a calendar method of contraception has been developed, through which it is possible to determine.

Important: the determination of fertile days is individual for each woman and depends on the duration of her menstrual cycle.

Rules for calculating fertile days:

• Monitor the duration of three menstrual cycles.
• Subtract 11 from the number of days in the longest cycle.
• From the number of days in short cycle subtract the number 20.
• The numbers in the range of the obtained values ​​are the days on which conception is possible.

For example: The duration of the maximum menstrual cycle is 31 days, and the short one is 29. Thus, 29 – 20 = 9; 31 – 11 = 20. This means that from 9 to 20 days from the start of menstruation, unprotected sexual intercourse may well result in pregnancy.

Probability of fertilization in a day

If timing of probable conception before ovulation last for a week and are explained by the viability of sperm, then after it, fertilization is possible for up to 2 days, which is how long a mature egg can live in a successful situation.

In addition, the first day after ovulation is when maximum fertility is determined.

IN female body at this time are created favorable conditions for the penetration of sperm into the egg, thanks to which male reproductive cells reach their goal within 2 hours after entering the vagina.

In a week

Pregnancy a week after ovulation is impossible due to a number of physiological factors:

• A mature egg lives no more than 2 days.
• The maturation and release of an egg occurs only once in the menstrual cycle.
• The process of fertilization is impossible without an egg.

Conception in a week after the woman's supposed ovulation can only be explained by a disruption of the menstrual cycle. That is, the release of the egg from the ovarian follicle occurred somewhat later.

Possible causes of delays in egg maturation:

• Irregularity of the menstrual cycle.
• Hormonal imbalance.
• Drug therapy.
• Stress factors.

Doesn't always give accurate results. An error of up to three days is allowed., which also gives reason to believe about possible conception a week after the egg matures.

How long is the likelihood?

Theoretically, fertilization can only occur with a viable female gamete, which persists for 24 hours after leaving the follicle. But in fact, conception is quite likely a few days after the expected release of the egg.

This factor due to inaccuracy. All home methods, even when used together, may produce some error, on average up to 3 days. Exact date the release of the egg can be determined only by ultrasound.

How to conceive a child with maximum chances?

Accurate determination of the date of maximum fertility important for women planning pregnancy.

Having sexual intercourse on an “auspicious day” significantly increases the chances of conception.

Fertilization is possible if coitus occurs within 48 hours after the release of the egg.

Peculiarity: optimal frequency of sexual intercourse in fertile days should be every 2 days. With more frequent contacts, sperm viability decreases.

Don't despair I am in the absence of coitus on the day of ovulation. Conception is possible within another 2 days. However, on day 3 the probability of fertilization is practically zero.

When to take the test?

The test determines presence of pregnancy based on concentration in a woman’s urine. The level of hCG begins to increase from the moment the fertilized egg enters the uterus, which occurs on the 5th day after fertilization.

Around day 10 After conception, highly sensitive pregnancy tests begin to respond to increased level HCG in the body of a pregnant woman by the appearance of a second indicator strip.

Attention: It should be borne in mind that the probability of detecting pregnancy by tests is 90%. The possibility of error cannot be ruled out.

On the 14th day after fertilization, pregnancy is determined even by tests with average sensitivity.

How not to get pregnant?

If sexual intercourse lasts for 5 days, and the birth of a baby was not at all part of the woman’s plans, it is recommended to resort to measures emergency contraception. For this purpose, you should take medications:

• Levonorgestrel.
• Postinor.
• Escapelle.

Data drugs suppress fertilization and prevent implantation of the zygote. They should be taken no later than 3 days after unwanted sexual intercourse.

To prevent an unwanted pregnancy from happening to your partner, it is necessary refrain from unprotected sexual intercourse c, using contraceptive methods, for 4 - 5 days after expected ovulation.

Pregnancy due to unprotected sexual intercourse after ovulation is quite likely. if coitus occurred within 2 days after the release of the egg. To avoid unwanted pregnancy, it is recommended to use contraceptive methods during fertile days.

For couples, those wishing to conceive a baby, “planning” should begin 5 days before the final maturation of the egg, maintaining a gap of 48 hours between sexual intercourse to preserve sperm fertility.

1. In practice, the question: when can a girl get pregnant is asked very often. In order for you to figure out for yourself whether you could get pregnant, you first need to understand how the reproductive system works.

When can a girl get pregnant?

A girl can become pregnant if she reproductive system ripe for conceiving and bearing a child. In this case, pregnancy occurs only when a follicle has emerged from her egg. This moment is called ovulation.

Normal, provided regular 28-day menstrual cycle, in which there are no deviations, Ovulation usually occurs two weeks after the onset menstrual bleeding, i.e. somewhere on the fourteenth day of the cycle.

According to scientists, an egg released from a follicle lives on average no more than 48 hours. But this is observed extremely rarely. More often she lives 24 hours.

Entered into a woman's genital tract sperm can live on average about 72 hours. IN in the rarest cases this period increases to 11 days. Conventionally, we take 72 hours.

High probability of getting pregnant between the 8th and 20th day of the cycle

Overlapping the life spans of the egg and sperm, it can be argued that favorable days to conceive a child, i.e. the days when a girl could become pregnant - provided she has a regular menstrual cycle (clear 26-day or clear 28-day) is the midpoint of the cycle, plus or minus five to six days from this midpoint.

Based on this, we can say with confidence: if unprotected sexual intercourse occurs these days or a condom breaks while protected, then the probability of pregnancy in this situation is quite high. During this period, the girl could become pregnant and the question becomes relevant: ? Everyone must answer this for themselves.

When is the likelihood of getting pregnant through unprotected sex low?

On all other days. If sexual intercourse occurred closer to the beginning of menstruation, for example, two to three days before menstruation or towards its end - on the fourth, fifth, sixth and seventh day of the cycle, the lower the likelihood of pregnancy. But not 100%. Why is this so? Because sometimes it happens that sperm lives longer or ovulation shifts to later or later early date. Therefore, all calculations are quite conditional.

But a certain rule still exists. It indicates the likelihood of pregnancy. Under the condition of a regular menstrual cycle, safe (closer to the end of menstruation) and dangerous days of the cycle (closer to the middle of the cycle) are distinguished.

Can a girl get pregnant during her period?

It is almost impossible to get pregnant during menstrual bleeding.

The exception is cases when ovulation for some reason occurred too early. But this happens extremely rarely. However, doctors are categorically against sex during menstruation.

This can be explained very simply - the likelihood of developing inflammatory processes in the uterus and endometriosis. To avoid harming yourself, you should abstain from sex during menstruation.

Sperm in the vagina - not 100% pregnancy

One more thing. If sperm gets into the vagina, this does not mean that pregnancy will occur one hundred percent. After all, a girl may not ovulate in every cycle.

In addition, the girl may have some additional factors that contribute to the failure of pregnancy. There may also be permanent reasons infertility or infertility in a certain cycle (for example, the corpus luteum is not fully formed or the follicle is not mature).

Infertility is a pressing problem

Not all men are able to fertilize if pregnancy does not occur.

It cannot be guaranteed that if in one of dangerous days, for example, the 14th, sperm gets into the vagina, the girl will definitely get pregnant. But the chance is high.

Here we need to remember that there are many infertile couples in the world who, throughout many months can have sex regularly, and pregnancy occurs only towards the end of the year.
