How to check ovulation by ultrasound. Ultrasound examination to determine ovulation: we understand the intricacies

Ovulation is a necessary process not only for the onset of menstruation, but also for fertilization with positive results. Very often, married couples cannot conceive a child the first time. And then the woman begins to calculate, take tests and look for all the external signs of the onset of ovulation. However, the only reliable and reliable way that gives a broad picture of everything that happens in a woman's reproductive system is an ultrasound examination of the ovaries to determine ovulation.

Indications for ultrasound for ovulation

When experts recommend doing an ultrasound of the ovaries to determine ovulation, it is important not to postpone this process, but to try to do it as quickly as possible. Indeed, there are many pathologies in the body and diseases in which monitoring is necessary.

An ultrasound scan to determine the presence of ovulation is mandatory in such cases:

  1. Painful periods. Stitching, cutting pain in the lower abdomen;
  2. Lack of menses for two months or more
  3. Pregnancy planning;
  4. Lack of a mature egg or its incomplete maturation;
  5. Follicle growth stimulation;
  6. IVF conception;
  7. Infertility diagnosis, treatment;
  8. Preparing to conceive a child after a miscarriage or abortion;
  9. Hormonal imbalance, poor hormone blood test result;
  10. Choice of contraceptives.

The monitoring of the ovaries will help not only to fully examine them, but also to find out the size and dominance of the follicle. Ultrasound is designed to determine the moment of release of a mature egg and allows you to see the corpus luteum.

Test methods to determine ovulation

There are several methods for monitoring the ovaries. The method of administration is chosen by the attending physician based on the patient's complaints and the presence of certain diseases.

Ovarian ultrasound is:

  1. Transvaginal - standard monitoring for the study of the pelvic organs. When a woman needs to do an ultrasound examination of the ovaries to determine ovulation, most often an ultrasound specialist performs it in a transvaginal way. A condom is put on the transducer and inserted into the vagina. The procedure is painless and takes about 20 minutes. There is no need to prepare for it in advance, the main thing is an empty bladder. Therefore, a woman must definitely go to the toilet before an ultrasound scan;
  2. Transrectal - the study is carried out to determine the infection or diseases of the genital organs in virgins and elderly women. The technique for conducting such a scan is identical with the transvaginal method;
  3. Transabdominal - Ovulation is determined by monitoring the abdominal wall. The specialist applies the gel to the pubic abdomen and examines the ovaries with a transducer. This method of determining ovulation is not very informative compared to transvaginal and requires preparation for conducting:
  • Do not overeat or eat food that can cause gas in the large intestine;
  • Drink a lot. The more the bladder is filled, the more reliable the information about the ovaries will be;
  • Empty bowel

This ultrasound monitoring is often done for pregnant women after 12 weeks.

Transabdominal ultrasound

When to do ovarian monitoring?

This scan should be performed at least four times. This is how you can determine in detail the rupture of the follicle membrane, the maturation of the egg and its release into the uterine cavity, the corpus luteum and the beginning of the ovulatory process as a whole.

If a woman has a classic menstrual cycle of 28 days, then monitoring should be carried out every 3 days:

  • The first ultrasound scan takes place on the 10th day of the cycle. The general condition of the uterus and ovaries is determined. Identify certain violations that can contribute to the lack of ovulation;
  • The second monitoring is carried out on the 11-13th day. The specialist detects the presence of a follicle, its dominance, membrane and full development. The regression level is set;
  • The third diagnosis should be done in the middle of the menstrual cycle, about day 14, when the follicle membrane should rupture. The course of the ovulatory cycle and the release of a mature egg are determined;
  • The fourth ultrasound is a control one. The specialist must make sure whether ovulation really took place, and whether a yellow body appeared after it. It is at this time, when the egg leaves the follicle, the woman's whole body may ache, migraine worsens, sharp pains in the lower abdomen and other unpleasant sensations appear.

Special attention should be paid to the latest ultrasound diagnostics. Only after it is carried out can we speak with confidence about the success of ovulation. The corpus luteum also plays a significant role. After all, it is responsible for the production of the hormone progesterone. If a mature egg has not entered the uterine cavity or is absent altogether, the specialist most often recommends continuing monitoring of the ovaries until the onset of menstruation.

This is important to know! If a woman has a regular menstrual cycle, then the start of the scan shifts, and should take place only four days before the middle of the cycle. In case of irregular periods, ultrasound is performed after the end of menstruation in 3-4 days.

Purpose of ovarian ultrasound. What can you see?

Many women determine the onset of ovulation using a special test. However, it happens that the test is not always able to show truthful information and accurately identify the presence or absence of an ovulatory cycle. Such inaccuracy is associated primarily with the quality of the test itself and the individual characteristics of the woman's body.

Correctly carried out monitoring at a certain time gives true information about the condition and readiness of the genitals for ovulation.

When ovulation has occurred, an ultrasound scan will show:

  1. Absence of the follicle and its shell;
  2. The presence of a mature egg in the uterine cavity;
  3. Yellow body, formed from follicular debris;
  4. The presence of fluid behind the uterus.

When the release of the egg did not take place and ovulation did not occur, monitoring will reliably determine the cause and identify possible violations:

  1. Stopping the development of the dominant follicle, its decrease in size. Regression;
  2. Full maturation of the follicle, no rupture of its membrane and no release of the egg into the uterus;
  3. The corpus luteum, which can form not only after ovulation. So, with luteinization of the follicle, when it is fully developed, matured, but not burst, it can develop into a yellow body;
  4. follicle. May occur if the egg does not come out;
  5. Lack of ovarian follicular production. Ovulation occurs only after the complete maturation of the follicle.

Ultrasound for ovulation and pregnancy

If a married couple is unable to conceive a child throughout the year, the gynecologist may advise the woman to undergo an ovarian scan to determine the auspicious day for conception - ovulation. Of course, you can use other methods - measuring basal temperature and plotting, calculating days by calendar, a special test. But as mentioned earlier, very often errors occur in the results obtained, therefore the most reliable and reliable method for determining ovulation is ultrasound, which is especially important when planning pregnancy.

It is worth paying attention to the psychological side of scanning. Only after the monitoring has been carried out, the specialist will tell you exactly the day when the fertilization of the egg and the upcoming pregnancy should take place. In other methods, this cannot be done.

Most experts recommend an ovarian ultrasound scan to determine ovulation as early as possible. Do not delay this procedure. Such timeliness will help not only to quickly become pregnant, restore the menstrual cycle and its regularity, but also exclude possible violations of the reproductive system.

Ultrasound diagnostics (ultrasound) has firmly established itself in our life, each person examines his organs using ultrasound several times a year. But this type of research is of particular importance for women, because transvaginal ultrasound is a reliable and accurate way to assess the state of the organs of the reproductive system, sometimes it is the only available way to carry out reliable diagnostics. Thus, ultrasound is an integral part of a woman's life.

Sometimes you hear such a term - "ultrasound during ovulation." Unfortunately, not all women, due to poor sex education, know what this process is, its signs and on what day of the menstrual cycle it can be determined. Not every woman knows why it is necessary to do such an ultrasound, how it differs from the usual transvaginal, when it should be done and whether such an examination is mandatory for everyone. Answers to these and other questions will help you understand the situation.

How does the ultrasound process go?

What is ovulation?

Ovulation is a key step in a woman's menstrual cycle, allowing her to conceive a child.... At this moment, the follicle that has matured in the ovary is ruptured into the fallopian tube, thus the ovum is “released”. Further, this egg passes into the fallopian tube, where it meets with the sperm, fertilization and transportation to the uterine cavity.
Thus, the main point of ovulation is the release of the egg to meet with the sperm.

Cyclic process of oocyte formation

The process itself is divided into several stages:

  1. The early phase (at this stage, several follicles can ripen in the ovary at once, however, only one (in rare cases this figure is higher) is ahead of its "fellows" in growth and development - these are signs of a dominant follicle. Its size can reach about 15-20 millimeters , while the rest stop their development and "fade out").
  2. Exit from the ovary (the dominant follicle can reach a size of 25 millimeters and then continues its way into the fallopian tube - it is with this size that the ovulation process and further conception are possible).

What is this research?

Any ultrasound examination is based on the principle of echogenicity - the ability of tissues to reflect ultrasound. Fabrics of different densities reflect it in different ways, so the screen displays an image of different shades: from black to white; in this way a "picture" of organs is formed.
It is important to note that it is absolutely safe to do ultrasound monitoring, since such rays do not bring any harm to the body, do not irradiate the follicles, as it is believed from ignorance, and do not have a negative effect on the future fetus. After such an examination, no negative reactions are also unacceptable.

Why carry out such a diagnosis?

The main goal is to track the moment of ovulation. In a normal situation, this moment, of course, is important for a woman's health, but does not require mandatory monitoring.

But everything changes if the patient is going to get pregnant, because it is when the egg is released that the most favorable moment for conception occurs. Thus, ultrasound is an excellent and effective way to detect this process: ultrasound monitoring allows you to determine both the maturation of the follicle and the immediate release of the egg.

Also, when planning a pregnancy, it is important to determine how healthy a woman is, whether pathological processes are developing in her body, whether she is ready to bear a fetus, to note signs of incipient abnormal processes. Therefore, in addition to the main function of such an ultrasound, the diagnostician performs a study of the entire reproductive system of the patient.

When is it held?

Ovulation is a phenomenon that occurs only once in the entire menstrual cycle. Ideally, this moment occurs in the middle of the cycle, about 10-14 days, this time is the most favorable for monitoring in order to determine the right moment for conception in time, because after it will be too late. The maturation of the follicle must be monitored every couple of days until the ovulation process has definitely occurred to ensure that the reproductive system is functioning normally.

The ultrasound picture is close to ovulation, the dominant follicle is visualized

Is it possible to notice the moment of release of the egg without ultrasound?

The body usually signals the woman in every possible way that the very long-awaited moment has come, it happens 10-14 days from the beginning of menstruation. The signs are quite typical, and they can be noticed even without a medical education. Indirect signs of ovulation are usually the following:

  • The amount of discharge increases to one tablespoon per day. It is important that they should be transparent, colorless and odorless, viscous. Blood, a strong unpleasant odor and abnormal color should raise suspicions about the course of the disease in the woman's body.
  • Follicle rupture can be accompanied by both pulling and severe sharp pain in the abdomen.
  • Libido is increased.
  • Changes in hormone levels occur after the follicle leaves.
  • Soreness of the mammary glands is possible.


In any case, these signs may appear on other days of the menstrual cycle, or they may not appear at all, so you should not blindly rely on them. After all, ultrasound monitoring is the only reliable way to find out about the right moment for conception.

Do you need specific training?

Since ovulation is a process independent of the patient's preparatory measures, almost no special preparation is required. You just need to perform a simple hygiene algorithm (go to the shower before going to the doctor, put on fresh underwear). It is advisable to do an ultrasound scan when the bladder is empty, fullness will interfere with the specialist's research and objectively evaluate the data obtained.

How is the ultrasound process itself?

A woman needs to take off her clothes below the waist, lie on the couch on her back, bend her knees and slightly push them apart. The diagnostician puts on a special condom on the elongated transducer, lubricates it with a special gel to improve the ultrasound conductivity and makes the examination more comfortable, and inserts it into the patient's vagina. Then, by turning the sensor at different angles, the specialist receives an image of internal organs on the monitor screen and evaluates it in accordance with ultrasound standards.

After completing all the necessary manipulations, the doctor displays the sensor. Then the obtained data is decoded and the indicators are compared with the norm, a conclusion is drawn up, a snapshot is printed and attached.

Such an ultrasound examination takes no more than fifteen minutes, and it is also convenient in that it does not in any way affect the state of the patient's body after, and she, only leaving the doctor's office, can do her usual things.

Is this ultrasound diagnosis related to pain?

Despite the fact that this procedure is unpleasant on a psychological level, physically it does not cause any painful sensations. It may be a little uncomfortable and unpleasant when the doctor rotates the sensor as needed, but in any case it is not associated with pain. Also, inserting the sensor into the patient's body cannot injure the vagina and internal organs, as well as affect the ovulation process.

What exactly is the specialist evaluating?

The diagnostician traditionally assesses the size of the ovaries, the number of developing follicles, the presence, size and localization of the dominant follicle, notes the presence and development of the corpus luteum. At the same time, the doctor examines all other organs and tissues of the reproductive system to make sure the patient's health.

How does the echographic picture manifest during ovulation?

If the menstrual cycle is not accompanied by any abnormalities, then the diagnostician during the examination notes the following: the presence of a follicle of sufficient size for the ovulation process directly in front of it, during ovulation, the disappearance of the dominant follicle is noted and the first signs that indicate that the corpus luteum begins to form.

Do I need to carry out an ultrasound after?

Yes, in order to make sure that the natural processes are normal, it is advisable to do a control ultrasound when the follicle has already burst. After the ovulation process, a yellow body appears in the ovarian cavity and free fluid is present in the small pelvis. Also, after the ovulation process, pathological situations may arise, although at first glance everything looks normal.

Is it possible to detect any pathologies on such an examination?

Since the doctor, using ultrasound, examines not only the ovaries and fallopian tubes, but also the entire area of \u200b\u200bthe appendages, it is possible to detect not only anomalies directly related to the object of study, but also pathologies of all organs of the reproductive system. Traditionally, the following pathologies can be seen on ultrasound:

  • Failure in the menstrual cycle (the main symptom is the absence of a mature follicle in the corresponding period, the absence of developing follicles, the absence of signs of the corpus luteum after the ovulation process).
  • Atresia of the dominant follicle (in this case, the follicle, having reached the required size, suddenly stops its further development and begins to regress; this pathology is usually indicated by the fact that the corpus luteum did not appear, in addition, any fluid also cannot be seen in the retuterine space, since the ovulation process has not ended).
  • Neoplasms of a malignant or benign nature.
  • Ovarian cysts.
  • Myoma (neoplasm of the muscle tissue of the uterus of a benign nature).
  • Endometriosis (the main signs are the proliferation of the upper layer of the uterine epithelium, bleeding and abdominal pain).
  • Soldering the fallopian tubes.
  • Adenomyosis (growth of the endometrium of the uterine cavity into other layers, as well as muscle tissue).
  • Follicular cyst (occurs if the follicle reaches the desired size, but does not stop its development. The size of such a follicle exceeds 25 millimeters, this is due to its filling with liquid. In the future, it does not rupture, and therefore the release of the egg into the cavity peritoneum).

Is there a chance of medical error with such an ultrasound scan?

Not to notice the ovulation process or to confuse it with others is quite difficult even for a novice specialist, therefore, ultrasound for this purpose is reliable in 95% of cases. However, the human factor in ultrasound examination cannot be excluded. An inexperienced diagnostician can incorrectly put the pathology of the organs of the reproductive system, thereby embarrassing a woman, because in this case she will no longer plan to conceive a child, but can treat non-existent diseases.

In case the patient suspects the specialist of incompetence, it is worth contacting another clinic for examination. A blood test can also clarify or confirm the result of ultrasound monitoring, an elevated level of the hormone progesterone indicates an ovulation process. These methods can be combined for more productive planning of a woman's future pregnancy.

Ultrasound examination for the diagnosis of the ovulation process is an effective method of planning pregnancy. Ultrasound has many advantages: painlessness, accessibility, accuracy, reliability. This diagnostic method is preferable when it is necessary to detect the development of the follicle and its exit from the ovary, since the echographic signs of the ovulation process are more indicative than external signs.

A regular menstrual cycle and monthly ovulation are essential for pregnancy. But with violations of the menstrual cycle in women, it is not always possible to calculate the exact time of the ovulatory phase. And here ultrasound monitoring comes to the rescue, which allows you to track the exact time of the release of the egg from the follicle. And if this does not happen, identify the cause. This ultrasound has its own characteristics - it is done several times a month and according to a specific method.

What is ovulation?

The number of eggs in a woman's body is genetically programmed and is laid even during the mother's pregnancy. Immediately after birth, a girl's ovaries contain up to 2 million follicles - a kind of cell islets. These are incubator cells where eggs are stored for the time being. By the beginning of puberty, the follicles contract - there are about 300 thousand of them.

A woman's monthly cycle is the sequential development and death of follicular cells. The cycle consists of three phases:

  • Folliculogenesis - the follicle gradually matures.
  • Ovulation - the follicle becomes thinner, and an egg cell appears from it.
  • Luteal phase - the "spent" follicle turns into a yellow body.

During the period of folliculogenesis, a sexual mini-incubator goes through several stages of development: primordial (primary), secondary and preovulatory (tertiary).

Then comes the shortest phase - ovulation itself. At this time, the follicle has already grown strongly, its walls, under the influence of hormones, become thinner, torn, and the egg cell is released. And then it moves along the fallopian tubes towards the uterus, waiting for the sperm to fertilize it.

At the last stage of development, the burst follicle turns into a corpus luteum and begins to produce the pregnancy hormone progesterone. If pregnancy does not occur at this stage, the corpus luteum dissolves.

Why do you need ultrasound ovulation monitoring?

A woman's menstrual cycle consists of several phases and usually lasts 28 days. This duration is considered ideal, but a normal cycle can last from 21 to 35 days. A deviation from the norm is considered to be a shift in both directions by more than 10 days.

With a stable cycle of 28 days, it is quite simple to find out the onset of the release of the egg (ovulatory phase) - the calendar method, basal temperature, external signs. If the cycle gets lost, all of these methods can already fail. There are also situations when, with an outwardly normal and clear cycle, the ovulatory phase simply does not occur. In these cases, it is necessary to control the menstrual cycle using ultrasound.

This ultrasound has several names. Ultrasound monitoring of ovulation, ultrasound screening of the follicle, folliculometry. The purpose of this procedure is one - to monitor the development of the follicle from the first (primordial) stage to the release of the egg.

The advantages and disadvantages of folliculometry can be reflected in the following table.

Benefits of the procedureDisadvantages of the procedure
makes it possible to assess the general condition of the uterus and ovaries, depending on the phase of the cycle;there is no way to assess the patency of the fallopian tubes;
allows you to trace the sequential development of follicles (or identify cases when it is not);does not show adhesive and inflammatory processes;
gives predictions about the timing of ovulation, allows you to recognize its signs;ultrasound needs to be done several times (at least 4 times per cycle), sometimes 2 cycles in a row are analyzed
makes it possible to observe the development of the endometrium and recognize pathologies in time;monitoring must be done strictly on certain days.
allows you to name the reasons why the ovulatory phase does not occur;
helps to find out the causes of menstrual irregularities and then choose the necessary treatment program.

How is the procedure performed?

An ultrasound examination of the pelvic organs in women is done using three different techniques. But when ultrasound monitoring is needed to determine ovulation, only one technology is used - transvaginal (internal) ultrasound.

For this examination, an intracavitary vaginal probe is used. The procedure is completely painless and does not bring the slightest discomfort to the patient.

Ovulation control with ultrasound is prescribed only after visiting a gynecologist and a comprehensive examination. The main disadvantage of ultrasound screening is that it must be repeated several times during the cycle. If there were no positive results, after the first month, it is necessary to repeat the entire monitoring.

But all these inconveniences are compensated by the fact that the ultrasound procedure does not require preparation at all. If before transabdominal ultrasound you need a special diet, preparation of the intestines and urinary tract, then folliculometry does not imply anything like that. You just need to go to the shower before visiting the ultrasound room. As before the classic visit to the gynecologist.

When do you need to monitor ultrasound ovulation?

When is ultrasound monitoring of follicles necessary? Before determining the timing of the procedure, the doctor must conduct an examination and understand whether the patient needs this procedure.

The list of indications for folliculometry is quite wide:

  • dysmenorrhea (painful periods);
  • amenorrhea (absence of menstruation);
  • irregular menstrual cycle;
  • preparation for IVF;
  • infertility treatment;
  • planning pregnancy after an abortion, miscarriage, frozen pregnancy, etc.;
  • poor results of laboratory tests (for hormones), etc.

Ultrasound screening consists of 4 procedures for the entire period of the menstrual cycle. Only under this condition it is possible to trace the entire period of follicle development and "catch" ovulation. And also to see signs that the egg has left and set off on its way to the uterus.

The first ultrasound is done at the beginning of the cycle, the rest - with a gap of 2-3 days. The exact timing looks like this:

  • 8-10th days of the monthly cycle. This is the time when the dominant follicle is already visible among 4-6 maturing ones (the rate may vary).
  • 12-13th days. The scan should confirm the presence of a dominant mass.
  • 14th day. The ovulatory phase is about to begin.
  • 17-18th days. Signs that the egg has come out need to be confirmed.

It is important to note that these dates are only valid for a well-defined cycle of 28 days. If the cycle is shorter or longer (but at the same time regular!), Monitoring is carried out 4-5 days before its calendar middle. And if it is irregular, then the first ultrasound is done already on the 4th day after menstruation.

How to recognize ovulation or its absence on an ultrasound scan?

One of the main signs that the ovulatory phase is approaching is the dominant follicle. An ultrasound scan allows you to clearly see it - the follicle looks like a round heterogeneous formation. The main signs of the "main" follicle with a maturing egg inside are:

  • the follicular incubator has grown to 17 mm or more;
  • it has a clear double contour; a fragmentary thickening along the inner contour is visible.

If the ultrasound shows that the follicle has only grown to 15 mm, the release of the egg is not guaranteed. Even signs such as the appearance of a corpus luteum a week after this scan do not guarantee that there was an ovulatory phase. When ovulation occurs, a follow-up ultrasound scan shows the following:

  • the dominant follicle is no longer visible on the monitor;
  • a yellow body appeared (resembles a rounded sac with uneven, deformed walls);
  • a small accumulation of fluid has formed in the Douglas space (this is the deepest place in the abdominal cavity, behind the uterus).

However, the maturation of the egg and its "hatching" is not always guaranteed, even with a perfectly clear, regular menstrual cycle. If the follicle has not matured to the final stage and has not released the reproductive cell outside, the signs on the ultrasound will be as follows:

  • regression (the follicle decreases in size);
  • persistence (the follicle matures, but the egg does not come out);
  • luteinization (the follicle develops as expected, but does not rupture and then turns into a yellow body);
  • follicular cyst (an unopened follicle accumulates fluid and continues to grow up to 25 mm or more, turning into a cyst);
  • follicles simply do not develop (there are no signs of the dynamics of their development on ultrasound).

Many gynecological diseases are among the reasons why the egg cannot mature or leave the follicle. These are endometriosis, polycystic, ovarian inflammation, etc. After detecting any pathology, the doctor will definitely prescribe additional tests, examinations and adjust the treatment tactics.

When in the life of a married couple there is a desire to have a child, but there are difficulties with conception, then the question of the onset of ovulation becomes the most important and priority. It is during this period that the probability of fertilization has the greatest chance of being realized.

To determine for sure whether ovulation has come, it is necessary to do folliculometry - an examination of a woman's reproductive organs using an ultrasound apparatus. Ultrasound helps in determining the dynamics of follicular development and possible causes of difficulties in conception.


A follicle is a "capsule" in which an egg matures and develops, and folliculogenesis is the process of follicle maturation. During ovulation, the follicular cavity ruptures and the egg cell capable of fertilization begins to move into the uterine cavity.

How is the folliculometry process going?

The examination is carried out with a transvaginal ultrasound probe, which is inserted directly into the woman's vagina, and does not carry any harm or painful accompaniment. The whole point is to determine the growth of the dominant follicle, the state of the endometrial layer and the development of the corpus luteum.
The monitoring results are displayed on the screen of the ultrasound machine and, as practice shows, are understandable only to the doctor. Therefore, do not hesitate and ask for an explanation of all the ongoing processes. The results of planned ovulation studies will be saved on the device and the doctor will use them to summarize the results of the entire examination.

When should an ultrasound be done?

The first ultrasound procedure of foliculogenesis must be done:

  • in the middle of the cycle, i.e. on days 9-10, provided that the cycle consists of 28 days;
  • with a regular cycle that exceeds or underestimates the average value (28 days), 4-5 days before its middle;
  • with an irregular cycle 3-4 days after the end of menstruation.

Ultrasound is repeated three more times at intervals of 2 days before the expected date of ovulation. If it never happened, then folliculometry is extended until the beginning of menstruation.
A week after ovulation, to confirm the results of the ultrasound procedure, it is necessary to do a blood test, in which an increase in the level of progesterone should be observed.

Signs That Determine Successful Ovulation

According to the results of folliculometry, the results of the examination are summed up. With a successful ovulation process, the following signs should be determined:

  • a dominant follicle with a size of 18-24 mm was found;
  • a yellow body formed at the site of the missing follicle;
  • for some time after ovulation, fluid is present in the posterior uterine cavity.

How to prepare for the procedure

Since folliculometry is a procedure planned in advance, the preparation takes place:

  1. for a clear and correct result, the study is carried out on an empty bladder;
  2. 2-3 days before the procedure, it is important to refrain from eating foods that can cause unwanted gas formation: raw vegetables, beans, peas, milk, alcohol, soda, etc. The last meal should be 12 hours before the procedure.

Folliculogenesis disorders

In life, not everything works out as you want, and couples who have problems with conception should be prepared for the violations identified during the ultrasound scan:

  • Follicle regression (reverse process). The process of formation and development of the dominant follicle, which went on exactly until a certain point, stopped abruptly and began to decrease. As a result, ovulation does not occur.

  • Follicle persistence (conservation). This phenomenon is accompanied by the preservation of the integrity of the follicular cavity, i.e. the expected rupture did not occur and the egg did not come out for fertilization.
  • Follicular cyst. The dominant follicle is ripe for the release of an egg from it, but this did not happen. The consequence of such a violation can be a follicular cyst formed from the fluid accumulated by the follicle.
  • Follicle luteinization. This violation is manifested by the formation of a yellow body, without rupture of the follicle. This could have happened due to a prematurely increased level of hormones or pathology in the structure of the ovaries.
  • There is no follicle production process. Ovulation with this deviation is impossible.

If an ultrasound scan of one of the abnormalities is detected, the doctor will prescribe a number of additional examinations and tests, and according to the results, treatment will be carried out, the purpose of which will be to normalize the hormonal balance and stimulate ovulation.

The psychological aspect of ultrasound

The ultrasound picture gives a complete description of the problem and the possible outcome. Other survey methods give an answer, but an ambiguous one, i.e. the woman remains in the dark and makes herself an unreasonable diagnosis: "there is no ovulation, so I am infertile", "today there is no ovulation, but tomorrow it will be", "there is no ovulation in this cycle, so it will never be."


Such thoughts will not arise in the head of a woman who has undergone an ultrasound of folliculogenesis, since psychologically she will immediately prepare herself for a correct and unambiguous answer.

How to determine ovulation yourself

In addition to ultrasonic research, there are other ways to determine favorable days for conception, which are available to every woman within the walls of her own home. To correctly determine ovulation, you need to learn to listen to your own body and correctly interpret its signs:


Any couple planning to have a child knows that the best moment for conception is considered. And this is perhaps the only moment when fertilization occurs. All other days remain "zero", that is, unsuitable for conception.

Naturally, every woman wants to know what these days are, when they fall and how they can be determined. There are many determination methods, but one of the most reliable is ultrasound (ultrasound). Today we will talk about this and much more in the article.

Ovulation is the release of an egg from the ovaries. In each representative of the beautiful part of humanity, this day comes at a different time in the cycle. It is generally accepted that it falls on the 14th day, but this does not mean that every lady can start planning a baby during this period. But it's all about the individuality of the organism.

Usually on the 14th day it comes to those women whose cycle consists of 28 days. Accordingly, if the cycle is shorter or longer, then day X is closer or further.

Many girls know when they have, because they feel their body like no other. It's simple, there are certain signs that indicate the approach of the period.

Consider the most common signs of ovulation:

  • Mucous discharge... Basically, the consistency and abundance of secretions always change. The so-called, which is secreted with the help of the cervix, becomes like a raw egg, more watery. In addition, the amount of discharge increases significantly.
  • Ovarian pain... Some ladies report aching pains in the ovarian area. Such pains can be short-lived, or they can last up to several days until ovulation stops.
  • Increased sex drive... Here, probably, Mother Nature did her best. For some reason, it happens that during ovulation you want sex more than on other days of the cycle. In this way, she tells the woman that this is the most.
  • Swelling and enlargement of the mammary glands... This condition is explained by a hormonal surge in the woman's body, because perhaps she will become pregnant this month.
  • BT... One of the clearest signs is. A jump in such a temperature can be noticed by those ladies who keep basal graphs and see any change in their body from them.
  • Cervix... On the gynecologist's chair, the doctor may notice some changes in the cervix. It becomes softer, rises higher and expands.
  • Changeable mood... On ovulation days, girls can become receptive to different tastes, and their moods can change instantly and frequently.

The above signs may not be present in a woman's life. Therefore, people took care and came up with special methods for determining ovulation.

Methods for determining ovulation

Even those women who can boast of a regular and systematic monthly cycle have periodic malfunctions in the body, and, as a result, ovulation abnormalities.

And about those girls who have permanent and there is nothing to say. Therefore, for everyone, there are special methods for determining ovulation. Each of them has a high degree of accuracy.

Methods for determining ovulation:

  • Test. The first method involves purchasing a special ovulation test. They buy it in pharmacies, shops, supermarkets and similar places. But here it is still better to give preference to state pharmacies.

The kit includes strips that look very much like a special chart, by which you can determine the expected days of the procedure.

The essence of the test is that a woman should urinate on it on the expected day. Luteinizing hormone, which is produced before ovulation begins in 1-2 days, should signal that it is time to plan for conception. That is, two strips will appear on the test, and this will mean that day X will occur within a maximum of 48 hours. If the test produces only one strip, it is worth repeating the procedure the next day.

The disadvantage of this method is its false indicator. This can happen when the test is made with a defect or the woman has ovulatory disorders. For example, premature luteinizing follicle, the structure of the ovarian membrane is quite dense. Another significant drawback is their high cost.

  • Basal temperature. Basal temperature measurement is considered a fairly popular and free way to determine ovulation. According to the temperature indicators, the girls build graphs, and when in the middle of the cycle they see a falling graph, it means that the egg has been released from the dominant follicle.

In this method, you should carefully consider the rules for measuring temperature. They are very simple and complex at the same time. need in the same place throughout the planning period, maybe a little more if you need to monitor the state of the fetus. It can be measured in three places: mouth, vagina and anus. In the rectum, the most accurate indicator is considered.

Further, it is necessary to measure it only after waking up, so that the body is in a state of calm for at least 4 hours. This should be taken seriously, because with any minimal movements, for example, going to the toilet two hours before waking up, will entail a false temperature reading.

If the rule above is observed, then you need to measure the basal rate as soon as you wake up. At the same time, do not make sudden movements. Therefore, it is worth preparing in advance: in the evening, set up an alarm clock for waking up and put it near you so as not to reach far behind it. Also put a thermometer next to you for the same reason. And as soon as the alarm rings, turn it off and insert the thermometer at the measurement point.

It is worth measuring with a thermometer for at least 5 minutes and during this try to lie as calmly as possible.

By the way, about thermometers: in principle, you can use any one if you are sure of it, but ordinary mercury ones are considered more reliable.

Another condition to be considered is the temperature measurement time. It must be the same. That is, regardless of weekends and working days, the time remains the same. For example, if on weekdays you measure your basal temperature at 6 am, then on weekends you continue to measure at 6 am. Of course, you won't be able to get enough sleep on your legitimate weekend, but this is a prerequisite if you want to get accurate indicators.

The disadvantage of this method, you guessed it, is self-control. It's hard to control yourself.

  • The calendar. The third method is the calendar method. It is not suitable for everyone, since not all women have a clear and constant cycle.

Its essence lies in determining the day of ovulation using a regular calendar. It was already mentioned a little above, but let us recall it again.

The very day of ovulation with a stable menstrual cycle falls in the middle. If a woman is 28 days old, then ovulation will occur on day 14. With this method of determining ovulation, it is impossible to say for sure when it will occur, so you also need to focus on your feelings.

  • Ultrasound... And the last, probably the most accurate method of determination is ultrasound monitoring (ultrasound). When to do it, what is its essence, we will consider below.

When is it most effective to do an ultrasound for ovulation

If he turns to a doctor with this question, he will independently determine the correct day for an ultrasound scan, calculating it according to the woman's cycle.

If the girl wants to go to the ultrasound office herself to observe the maturation of the follicles by day X, then she can also calculate the estimated date. If her cycle is systematic and constant, four ultrasound sessions will be enough for her.

The first day of the cycle is considered to be the first day of bleeding. Each cycle of a woman is individual. But, on average, on the 8-10th day of the cycle, it is worth going to do the first ultrasound. For example, if the cycle consists of 30 days, then the 10th day is exactly the day when they contact the monitoring office.

Those cases when a girl complains about, then on the third day after the end of bloody discharge, an ultrasound scan should be done.

  • Most likely, at the first monitoring, the follicle with a "surprise" should have a size of 1.5 cm.
  • The second ultrasound is done three days after the first and the follicle grows to a size of 2 cm, or even more.
  • The third examination should be the final one - the dominant follicle reaches its peak of 2.5 cm, after which it inevitably breaks.

It happens that on the second ultrasound, follicle regression is observed - this is a decrease in the size of the follicle. From which it follows that ovulation will never happen. In such cases, the doctor must determine the cause of this behavior and eliminate it, otherwise, conception may not be at all.

Or another situation, when the follicle has increased to the required size, and the release of the egg has not happened. Then the ultrasound is continued until the beginning of menstruation.

Therefore, it is so important to carry out monitoring over several cycles.

How is the folliculometry procedure performed?

Observations can be carried out in two ways:

  • Transabdominal... The patient lying on her stomach completely exposes her abdomen and pubis. The ultrasound sensor moves along the surface of the abdomen.
  • Transvaginal ultrasound using a vaginal probe. In this case, the patient should take off her underwear (panties), lie on her back, pull her knees towards herself and spread her legs. They put on a special ultrasound sensor and drive it into the vagina. This method involves internal research. This procedure is completely painless.

Folliculometry involves monitoring several indicators at the same time:

  • the growth of the dominant follicle;
  • the presence of a yellow body in the ovary;
  • the disappearance of the "empty" follicle after ovulation;
  • the appearance of free fluid in the pelvis.

In addition, if a woman donated blood at this time, the result will show an increased level of progesterone.

How to properly prepare for an ultrasound

In principle, there is no special preparation for folliculometry for ovulation. But there are small requirements: in this period, it is necessary to remove as much as possible from the diet products that provoke gas formation in the intestine, since they interfere with clearly seeing the follicles.

For example, these products include:

  • Legume family (beans, peas, similar);
  • Various cabbages;
  • Carbonated drinks, water with "bulbs";
  • Black bread;
  • Alcohol.

If the examination method is chosen transabdominally, then an hour before the ultrasound scan it is worth drinking a lot of clean and still water, at least a liter. And until the procedure is done, you cannot urinate. That is, this method assumes a full bladder.

Conversely, when the ultrasound method is vaginal, the bladder must be emptied. Therefore, visit the ladies' room before the procedure.

Advantages and disadvantages of ultrasound

As with any examination, the detection of ovulation by ultrasound has its advantages. Most of them.

But there is also one significant drawback - the high cost of the procedures. Although, not for everyone this can be called a disadvantage.

Despite this "drawback", the definition of ovulation through ultrasound gives a 100% result and expectations are justified.

The advantages of determining ovulation using ultrasound are obvious:

  • You can find out the day of ovulation using ultrasound monitoring with a 100% guarantee. An experienced doctor cannot help but see when the follicle is ripe and ready to exit.
  • With the help of ultrasound, many girls escaped and identified problems with the reproductive system at an early stage.
  • Another plus is that ultrasound helps to understand the origin of the violation in the monthly cycle. He will also show the state of the lady's endometrium.

The main and only drawback is its high cost. Judge for yourself, the procedure should be done at least four times per cycle, but you need to look at at least two such cycles.

In total, it turns out at least 8 times you need to contact the ultrasound office and, moreover, on certain days. And this is not only expensive, but also inconvenient, because it requires a lot of free time.

But, in principle, what a woman who dreams of motherhood will not do.
