Is there a chance of getting pregnant on the day of ovulation? What is the probability?

Your doctor will tell you what the probability of getting pregnant on the day of ovulation is. A woman's fertile period is unstable. Its development is influenced by various systems. To correctly determine when the ovulatory stage begins, it is necessary to use a variety of techniques. Calculating the most favorable day will help the planning family achieve results faster.

It is also necessary to take into account the general health of both partners. The presence of any pathologies can become an obstacle to the goal. You can also establish the general clinical picture at the medical center.

What is the probability of getting pregnant on the day of ovulation?

Ovulation is considered the most favorable period for conceiving a child; in its absence, pregnancy is simply impossible.
This period occurs approximately in the middle of the cycle (assuming the cycle is 28 days), and its maximum duration is 48 hours. If fertilization of the egg by sperm does not occur at this time, then conception is postponed until the next month. This nuance has natural reasons. After maturation, the egg in most women is destroyed within 24 hours. Percentage probability of conception during ovulation:

After the destruction of the egg, the chances of conception are reduced to 0%. But no matter how high the probability of conception, male sperm has a great influence on the fertilization process. If sperm are active and have a maximum lifespan, then they can literally “wait” for the maturation of the egg while in the fallopian tubes. If sperm quality is low, fertilization may not occur even at the most favorable moment.

ON A NOTE! Sperm can retain the ability to fertilize while remaining in a woman’s body for up to 5–7 days.

Mechanisms of ovulation

At the beginning of each menstrual cycle, one follicle in the egg is exposed to follicle-stimulating hormone. When the follicle, under its influence, reaches a certain size and becomes active, another hormone is activated - luteinizing hormone. It promotes the maturation of the egg. The follicle then ruptures and the egg leaves it. This moment is called ovulation. Now the female reproductive cell is available for sperm entering the uterus, conception can occur. In the absence of sexual intercourse during ovulation, the unfertilized egg is destroyed during the first day.

Factors that increase the chance of pregnancy

Certain factors can increase your chance of getting pregnant during ovulation. It is believed that you can get pregnant faster if you abstain from sexual intercourse for a while. Indeed, in this case, the concentration of sperm in the biological fluid will increase.

During ovulation, a woman is advised to avoid consuming caffeine-containing drinks and nicotine, since these products negatively affect the contractility of the fallopian tubes and contribute to changes in the ratio of sex hormones in the body. Preference is given to fruits, vegetables and products containing folic acid - peanuts, cheese, milk powder.

During sexual intercourse, it is advisable to avoid using lubricant. The components included in the gel prevent sperm from freely penetrating the fallopian tubes.

Certain positions during sexual intercourse can increase the likelihood of conceiving a child. For example, when a woman lies on her back with her legs thrown up. For ladies with a curved uterus, poses in which the man is behind are more suitable.

Often, the process of conceiving a child is hampered by a woman’s stress due to the inability to get pregnant. In this case, the lady is recommended to “free” her head from negative thoughts and spend some time in a calm environment.

The chance of getting pregnant during ovulation the first time is 33%. A woman can determine the optimal moment of conception by measuring rectal temperature or special test strips sold in pharmacies.

Symptoms of early pregnancy diagnosis

It must be said right away that the signs for early diagnosis of an “interesting condition” will be vague, so they can be confused with another pathological condition:

• Cramping pain in the lower abdomen. If ovulation has already passed, then in the event of fertilization of the egg, pain may be felt, moving from the lower abdomen to the side;
• Breasts may become swollen and painful, but this may be normal for women during the luteal phase;
• If one week has passed after ovulation, light bleeding may appear. Doctors call this condition implantation bleeding. It occurs during the period of attachment of the fertilized egg to the walls of the uterus;
• Toxicosis is unlikely to appear after ovulation, but bloating and excessive gas pollution in the intestines should alert you.

The surest way to detect early pregnancy is basal temperature. After increasing during ovulation, it will remain unchanged, that is, high.

Regardless of the chance of getting pregnant during ovulation, you can find out the exact result only after a few days of a missed period.

How to protect yourself

Ovulation does not last long - 2 days. You can get pregnant only during this period. Various reasons can shift these dates; it is not always possible to be completely sure that conception will not occur. Some sperm show miracles of vitality and are capable of fertilization even on the 10th day after ejaculation. The riskiest option is unprotected sex, even if it is coitus interruptus. Out of 10 women who become pregnant, 2 decide to have an abortion.

You can protect yourself from unwanted pregnancy with the help of contraceptives:

• mechanical - female and male condoms, vaginal diaphragms and cervical caps;
• chemical preparations – spermicidal tablets, gels, creams, suppositories;
• hormonal pills;
• intrauterine devices.

Each method has its own advantages and disadvantages. The gynecologist will advise which one to choose, taking into account the age and condition of the body.

The influence of female orgasm

Everyone understands that male orgasm or ejaculation is the main condition for fertilization during ovulation. But some experts say the female orgasm plays an important role during conception.

During orgasm, the uterus contracts and becomes soft, helping the sperm to reach the fallopian tubes. Of course, this is facilitated by simultaneous orgasm with your partner, but do not worry if this does not happen, because conception can occur without your orgasm , while

• stress
• and experience

in this regard, it will create the opposite effect and reduce the likelihood of getting pregnant .

Chances of pregnancy

A prerequisite for pregnancy is the meeting of two full-fledged, viable germ cells: male and female. Therefore, any sex during the period of release of the oocyte, if sexual intercourse is unprotected, or there is at least a minimal probability of sperm penetration into the woman’s genital tract, can theoretically lead to pregnancy.

It is important to understand that sexual intercourse that occurs a few days before the release of the egg can cause pregnancy. Sperm have greater vitality than the female reproductive cell, and they can exist in the female genital tract for up to 3–5 days without compromising their abilities.

Reproductologists estimate the chance of conceiving the first time with unprotected intercourse on the day of ovulation and within 24 hours after it (while the oocyte lives) at a maximum of 33–34%. This means that every third couple can conceive a child during this period. When having sex before ovulation one day, the chances of getting pregnant are estimated at 29–30%, two days before the release of the oocyte - 26-27%, three days before - 16%, four days - 10%.

In many ways, the probability depends on a wide variety of factors and may be lower under certain conditions. It is influenced by:

• age of partners;
• their health status;
• the presence or absence of bad habits.

The above percentage chances apply to couples who are in the prime of their reproductive period - 20–30 years. After 30 years, the process of aging of germ cells begins, and chronic diseases acquired by a man and a woman affect them. The ovarian reserve of women after 35 years is rapidly depleted; anovulatory cycles (in which ovulation does not occur at all) can occur 5–6 times a year. Spermatozoa also do not get younger over time, mobility is lost, the lifespan of germ cells is shortened, morphological changes appear, and therefore the probability of conception in a 35-year-old couple from the first time on the day of ovulation does not exceed 15%, and after 40 years it is no more than 1– 3%.

You can get pregnant in the ovulatory phase not only from unprotected sexual intercourse with full ejaculation. The probability of pregnancy is also quite high if sexual intercourse is interrupted. And the point is not even in the speed of a man’s reaction, as many believe, but in physiology. In men, full-fledged and mobile germ cells in small quantities can also be part of the physiological lubricant, which is produced quite naturally in a man in a state of sexual arousal.

The younger and healthier the couple, the higher the likelihood of pregnancy. This should not be forgotten either when planning the long-awaited conception, or when addressing issues of contraception. It is necessary to have sex during the period of ovulation to conceive, but for those whose plans do not yet include the birth of offspring, it is worth having sexual intercourse with a condom - barrier contraception has a high Pearl index, which indicates reliability.

Oral contraceptives are even more reliable. The principle of their action is hormonal suppression of ovulation, which means that while taking OCs the egg does not mature and is not released. Only protected sexual intercourse guarantees that there will be no “surprises”. A doctor should select a contraceptive for a particular woman.

Here are a few statistics on which the Pearl index for determining the effectiveness of contraceptives is based:

• with the use of oral contraceptives (OC) - pregnancy occurs in 0.03 -0.5 cases per 100 couples;
• with the use of an intrauterine device, an “interesting position” can occur in 2-3 couples per 100;
• with a condom - 5–10 women out of 100 become pregnant (usually due to mistakes by partners in using a contraceptive);
• with interrupted sexual intercourse, 15–20 out of a hundred women become pregnant.

How many days after ovulation can you get pregnant?

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

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

The most successful period for fertilization is 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 uterus: the consistency of the cervical mucus decreases and the elasticity of the vaginal walls increases.

On what days of the cycle is it possible?

The 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 sexual intercourse for pregnancy to occur must occur 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 possible days for conception can be determined.

Rules for calculating fertile days:

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

Probability of fertilization in a day

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

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

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

A week later

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 a week after a 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 disbalance.
• Drug therapy.
• Stress factors.

Determining ovulation at home does not always give accurate results. An error of up to three days is allowed, which also gives reason to believe that conception is possible 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 during unprotected intercourse and a few days after the expected release of the egg.

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

That is why gynecologists recommend that women, in order to avoid unwanted pregnancy, refrain from unprotected sexual intercourse for 5 days after ovulation.

Risk of conception during interrupted intercourse

Modern medicine offers many methods of contraception. To understand how effective the folk method - interrupted sexual intercourse - is, you need to compare different options for protection:

1. Condom. If the condom is put on correctly and does not break, it will 100% protect the girl from pregnancy. But a number of mistakes on the part of men, who may use a condom incorrectly, lead to a decrease in the effectiveness of contraception. Considering the small percentage of those who violate the rules of use and experience pregnancy, the effectiveness of the condom is 95%.
2. Intrauterine device. According to various sources, the effectiveness of this method is 80-90%. The problem is that this percentage decreases if the device is installed incorrectly or if the girl’s uterus has been exposed to various infections and inflammations. Therefore, this method of protection is usually used together with other methods - condoms or interrupted sexual intercourse.
3. Oral hormonal pills are contraceptives. According to various reviews, the effectiveness of the tablets is from 50 to 100%. The disadvantage of tablets is that they work correctly only if the doctor (or the patient himself) has chosen the medication perfectly and chosen the optimal frequency of administration. Even with small mistakes (incorrect dosage of the drug, missed days of taking, etc.) there is a high chance of conception. However, many girls use this method for years and do not get pregnant.
4. Interrupted sexual intercourse. This method is the least effective. Among girls with unwanted pregnancies, those who were protected using interrupted intercourse are in first place.

Zygotes are also released along with lubrication, which occurs at the very beginning of sexual intercourse. And although the zygotes that enter the vagina along with lubricant are often inactive and cannot fertilize an egg, in rare cases they can still lead to pregnancy.

The second reason why the probability of getting pregnant on the day of ovulation with interrupted intercourse is very high is that the time of ejaculation is very difficult to control. Sometimes men realize too late that ejaculation is about to occur. And there are also cases when they realize this in time, but due to a bad reaction or simply inhibition, they pull the penis out of the vagina too late. As a result, sperm penetrate into the woman’s genitals, and the most active ones are the first ejaculated zygotes; they have the greatest viability. They most often fertilize female sexual zygotes.

If intercourse is interrupted, the likelihood of pregnancy during ovulation is highest on the day the egg is dropped. This day (ovulation peak) is approximately the middle of the menstrual cycle. The average cycle for girls is 28 days. It is counted from the end of the previous menstruation. If 14 days have passed since menstruation, this means that ovulation is now occurring.

From the start of ovulation, it takes about 48 hours before sexual intercourse becomes safe again - two days after the start of the process (approximately the 16th day of the cycle), the egg is no longer able to meet the sperm. Therefore, it is advisable to avoid sexual intercourse during the period from 14 to 16 days of the menstrual cycle. Some girls have a different cycle length - 33 or 35 days. Then the time of ovulation must be calculated individually, preferably with the help of a gynecologist.

There is also a chance of getting pregnant if sexual intercourse occurs a week before ovulation. Sperm can remain active in the vagina for up to 7 days. If 6 days before ovulation the male zygote enters the vagina along with lubricant and remains viable, then conception will occur on the day of ovulation.

Probability of conception

It is a mistake to believe that the probability of conception on the day of ovulation is 100%. Experts explain that having sex during ovulation leads to pregnancy in 33–65% of cases. On some other days the probability of conceiving is also high.

After sperm enter the female body, they remain viable for some time. The chance to conceive a child exists when sexual intercourse occurs 1-3 days before ovulation. After the day of ovulation, the likelihood of getting pregnant is reduced to zero within a few days. Doctors recommend having sex every day for a week before ovulation.

Interesting! The patient’s desire to become pregnant plays an important role; experts note a direct relationship between the psychological state and the activity of the mature egg. If a woman has sex with pleasure during the week before ovulation, the man’s sensations and sensitivity increase, which also affects the possibility of conception.

There are cases when a woman had sex on a safe day, for example, 10 days before ovulation or a long period of time after the day the egg matured, but the result of sexual intercourse was pregnancy. This is explained by a sharp change in hormonal levels caused by taking medications and emotional stress.

Such a risk always exists, therefore, if conception is absolutely not planned, you need to know how to protect yourself with reliable means. The most common method of affordable contraception is sexual intercourse with a condom.

Possibility of conception on the day of ovulation

Ovulation occurs when the female reproductive cell matures and leaves the follicle. This period appears approximately 14-15 days after the start of menstruation. On the day of maturation, the egg ruptures and leaves the ovary.

A mature egg has no more than a day to become fertilized. In rare cases, double ovulation is diagnosed, i.e. when 2 mature cells leave the ovary with a time interval of 2 days.

You can become pregnant during ovulation. Therefore, every woman planning a child must learn to determine the beginning of this period.

In women in this position, egg maturation does not occur. This is due to the fact that the reproductive organ is already occupied and does not need mature cells for fertilization.

Cell maturation occurs irregularly in some women. The incorrect structure of the egg itself or its absence causes anovulation. In this case, the woman has no chance of becoming pregnant. The disorder occurs even with a regular menstrual cycle.

Anovulation is divided into:

Physiological, when the maturation of the egg does not occur for natural reasons. The condition does not require drug treatment and goes away on its own after a certain period of time. Physiological anovulation manifests itself:

• when carrying a child;
• after childbirth;
• during breastfeeding;
• during menopause;
• during the period of menstrual rest (a woman can go through several cycles without egg maturation);
• while taking COCs, which are aimed at suppressing ovulation.

Pathological. The condition develops due to various disorders in the woman’s body:

• diabetes mellitus;
• abnormalities in the functioning of the organs of the reproductive system and their damage;
• excess body weight;
• neurological abnormalities;
• inflammatory diseases of the fallopian tubes and appendages;
• liver failure.

With timely treatment of these pathologies, reproductive function can be restored.

A woman can independently determine the onset of ovulation by measuring basal temperature or by symptoms. During the period of egg maturation, some women feel slight discomfort in the lower abdomen. This condition is associated with the rupture of the follicle and the release of a mature cell from it. At this time, sexual desire also increases. It should be immediately noted that based on the listed signs it is impossible to identify with 100% probability the optimal time for conceiving a child.

A reliable way to determine the onset of ovulation is to measure your basal temperature daily. Normally, this figure is 36.9-37.1 degrees. During the period of egg maturation, the indicator rises to 37.5-37.7 degrees. If cell fertilization does not occur, the indicator returns to its original values. When pregnancy occurs, the rectal temperature remains elevated.

A woman who keeps a diary of measuring her basal temperature can accurately determine the best time to conceive a child. But the rule only works if the woman has a regular menstrual cycle.

There is another way to determine the optimal time for pregnancy - measuring LH in urine using test strips. Before the egg matures, a pink stripe appears on the test; the closer the ovulation phase is, the brighter the color of the stripe becomes.

How to determine pregnancy after ovulation?

A woman can understand whether conception has occurred, first of all, by the cessation of menstrual flow. However, the first signs of pregnancy after ovulation can be noticed even earlier.

Women who are accustomed to regularly measuring their basal temperature will, in case of pregnancy, observe its increase to a level of more than 37 degrees. Another sign: weak spotting, which is sometimes mistaken for the onset of menstruation. In fact, this is a minor endometrial detachment. Finally, a test at home will help determine whether conception has occurred.

It is effective even if there is a day or two left before the expected delay. The strip indicating a positive result will be visible, just a little smaller than at a later date. Finally, a sign of pregnancy after ovulation, which makes it possible to determine with almost one hundred percent accuracy that conception has occurred: an increase in the level of human chorionic gonadotropin.

This specific hormone is produced only in the body of a pregnant woman. A blood test to detect the presence of human chorionic gonadotropin is done only in a hospital setting.

How to calculate gestational age based on ovulation

If a woman used one of the methods described above to determine the date of her ovulation, then it will not be difficult for her to calculate the gestational age if conception has occurred. Of course, a small error is possible, but, in general, the result will be quite accurate, especially when using ultrasound monitoring.

If a woman did not track the onset of ovulation, then she can use the Naegele formula. It is used by gynecologists to determine the due date. To do this, subtract three months from the beginning of the last menstruation and then add seven days.

The doctor needs to know the timing of pregnancy in order to properly manage the patient during this period, prescribe examinations and tests in a timely manner, and monitor how the baby’s intrauterine development progresses.

An accurate determination of the gestational age is necessary in order to know the date of birth, because their premature or delayed onset negatively affects the health of the child. It is important for the woman herself to go on maternity leave on time and prepare for the birth of the baby.

Does ovulation occur during pregnancy?

Medical professionals answer this question in the negative. The fact is that pregnancy involves serious changes in the level of hormones in a woman’s body. These changes are aimed at preserving the fetus and bearing a healthy child.

In such a situation, the maturation of another egg, i.e. ovulation, creates a direct threat to the health of the woman and baby. Therefore, nature itself made sure that ovulation does not occur during pregnancy.

In addition to increasing the concentration of hormones, changes also occur in the woman’s reproductive organs. The ovaries stop releasing eggs for fertilization, and the cervix closes with a mucous membrane. If, theoretically, another conception were to occur, the fertilized egg would not be able to gain a foothold in the uterus.

Therefore, those women who are interested in whether ovulation occurs during pregnancy need not worry: ovulation does not occur during pregnancy.

Factors influencing conception during “after-hours”

Fertilization can occur if a mature egg leaves the follicle cavity and begins to move along the fallopian tube. As you know, ovulation is possible only on certain days of the cycle, so a woman can become pregnant only during the life of a mature gamete. However, sometimes pregnancy occurs unexpectedly for the expectant mother, even if, according to all calculations, conception was excluded.

This situation can occur under the influence of a number of factors. Unplanned pregnancy on “infertile” days most often occurs for the following reasons:

• Sexual contact took place in the period preceding ovulation. After ejaculation, sperm are able to survive and fertilize the female cell for 4-5 days. If an egg is released during this period of time, then a sperm ready for fertilization may already be waiting for it.
• Irregular cycle. If the length of a woman's menstrual cycle varies from month to month, then calculating the date of ovulation is very difficult. For this reason, pregnancy may occur suddenly, on a day that was considered safe.
• Stopping taking contraceptives. This factor also affects a woman’s hormonal levels and often becomes the cause of unplanned conception.
• A short cycle, not exceeding 28 days, increases the chances of pregnancy immediately after the end of menstruation, since with a slight deviation from the period, ovulation occurs at this moment.
• Early or late ovulation. If the cycle fails, premature or late maturation of the female cell is possible. At the same time, the woman seems to make the correct calculations, but conception occurs contrary to all assumptions.
• Two ovulatory phases in one cycle. This phenomenon is quite rare; a woman usually does not know that during one menstrual cycle she has time to mature two gametes. With such a deviation from the norm, the risk of unplanned conception increases by 2 times, since the woman is not aware of her peculiarity.

The onset of pregnancy on days when theoretically conception cannot occur also occurs under the influence of external factors. So, unexpectedly for a woman, conception occurs under the influence of the following reasons:

1. Stressful situations. Regular exposure to stress and a stressful work schedule can affect a woman’s general health and contribute to the occurrence of hormonal imbalances and abnormalities in the menstrual cycle. Due to stress, the oocyte may mature ahead of time and be ready for fertilization.
2. Increased lifespan of male and female reproductive cells. Sometimes the sperm survives up to 7 days with a favorable level of acidity in the female tubes, and the life of the egg in some cases lasts up to 2 days.
3. Diseases. Periods of fighting the disease often disrupt the female cycle, so the calculations turn out to be incorrect.

Factors that reduce the chance of conception during ovulation

The probability of pregnancy during ovulation is very high, but the health of both partners . If a man or woman has any abnormalities in the functioning of the internal systems or reproductive organs, then the chances of conception are reduced.

The chances of getting pregnant during ovulation are reduced if the following factors :

• the favorable day is incorrectly calculated (ovulation may be early, late, timely or absent, despite menstruation);
• hormonal imbalance (this condition can be provoked by certain medications, stressful situations, taking contraceptives, as well as a number of other factors);
• congenital pathologies of the uterus and other reproductive organs (in some female representatives, the structure of the reproductive organs and their functioning are congenital abnormalities, the chances of getting pregnant if they are present are reduced regardless of the natural processes in the body);
• deviations in the functioning of the female reproductive organs, as a result of which the egg has not matured (this condition may also be an individual feature of the female body, especially at a young age and irregular menstrual cycles);
• low quality of sperm in a man (a man can find out this circumstance by passing special tests);
• the woman has had an abortion or has been diagnosed with obstruction of the fallopian tubes (the cause of this condition in most cases is adhesions that occur after a medical abortion);
• exposure to external adverse factors (for example, constant stressful situations);
• immunological incompatibility of partners (for example, the presence of antibodies).

It is possible to determine whether pregnancy has occurred on the day of ovulation 7–14 days after fertilization of the egg. This can be done using a test. By this time, the hCG will already begin to be produced in the woman’s body. In addition, characteristic symptoms will help to recognize conception.

REFERENCE! The likelihood of fertilization is influenced not only by external factors and the health status of the partners, but also by their age. The older a woman is, the less likely she is to conceive a child.

How often do you have sex?

In order to increase the chances of fertilization, you should not make love every day.

It is desirable that a new female reproductive cell meets an equally fresh male cell. This will increase the likelihood of successful fertilization.

But this does not mean that there is no chance of getting pregnant if the act of intimacy takes place on other days that do not coincide with ovulation.

IMPORTANT! The quality of sperm and its quantity improves if sexual intercourse is not too frequent - the male body needs full recovery. Then the activity and viability of sperm is much higher than during daily sexual intercourse. Even with a regular cycle, changes in the date of ovulation are possible under the influence of external factors

Even with a regular cycle, changes in the date of ovulation are possible under the influence of external factors.

Among them are the following:

• Sports, dancing.
• Stress, increased fatigue.
• Nutritional features.
• Lifestyle.
• The presence or absence of bad habits.
• General health.

You can focus on your inner feelings. With increased sensitivity, a woman always notices the onset of ovulation - the optimal period for the birth of a new life. Nature itself has provided for everything.

INTERESTING! At this time, sexual desire intensifies, the nature of vaginal discharge changes - a favorable environment is prepared for the fusion of masculine and feminine principles. The woman herself feels that the time has come for sexual intercourse.

Each couple is given the choice to decide for themselves how often to have sex, because you can never accurately predict at what point ovulation will occur and fertilization will occur.

The main thing is that the intimate act also brings satisfaction to both partners. Then the birth of a new life will occur in an aura of love and tenderness, which will have a positive effect on the future baby.

What happens during this period?

The ovulatory phase usually occurs in the middle of the female menstrual cycle. It occurs two weeks before the start of the next menstruation. Therefore, for simplicity of calculations, it is proposed to subtract 14 from the total duration of the cycle. This is how long the second half of the cycle usually lasts - the luteal half. On the day of ovulation, a mature egg is released from a follicle located on the surface of the right or left ovary.

With double ovulation, which happens very rarely, two or more follicles mature at the same time, and more than one germ cell may be released. Cycles with double ovulation increase the likelihood of multiple pregnancies.

In order to mature, the sex cell takes time. From the very first days of the new cycle, several follicles mature in the ovaries under the influence of the hormone FSH. They are called antral. Of these, by the 7th–8th day of the cycle, the undisputed leader stands out - the dominant follicle, it grows faster and more intensely, while the growth of the rest slows down and reverse development occurs.

It is in the dominant follicle that the reproductive cell matures, without which a woman will not be able to conceive a child. 2 days before ovulation, estrogen levels increase, which leads to a surge of the LH hormone.

• Menstruation
• Ovulation
• High probability of conception

Ovulation occurs 14 days before the start of the menstrual cycle (with a 28-day cycle - on the 14th day). Deviation from the average value occurs frequently, so the calculation is approximate.

Also, together with the calendar method, you can measure basal temperature, examine cervical mucus, use special tests or mini-microscopes, take tests for FSH, LH, estrogens and progesterone.

You can definitely determine the day of ovulation using folliculometry (ultrasound).

But speaking of ovulation, one cannot help but say that the phase lasts exactly as long as the female reproductive cell lives. But nature didn’t give her much time - from 24 to 36 hours maximum. It is during this time that the gametes of a man and a woman must meet in the fallopian tube, merge and exchange DNA to form a new cell - a zygote.

On the eve of ovulation, nature sends women special “tips” that are designed to draw the attention of the fair sex to changes leading to high fertility. Libido increases, the woman is in a “playful” mood, the amount of cervical mucus increases - because of it, the discharge becomes more abundant, transparent, viscous, like raw chicken egg white

Some people also experience other symptoms, for example, pain in the area where the ovulating ovary is located.

You can more accurately determine the onset of ovulation using home ovulation tests, which are very easy to use. They respond with a second stripe to high levels of luteinizing hormone in the blood, and the LH surge occurs 12–24 hours before ovulation.
