Ovarian pain is a scourge modern woman. All more diseases reproductive system proceeds with complications, modern mini fashion promotes hypothermia and infections, ovarian dysfunction calls into question the ability to reproduce huge amount representatives of the fair sex.

So why do the ovaries hurt, what are the causes of discomfort in this area?

1. Depending on which part of the ovary hurts, there are two types of inflammation. If the ovary itself is inflamed, a diagnosis of adnexitis is made. Inflammation of the ovaries, or adnexitis, is provoked infectious process, among the pathogens of which one can find microorganisms that cause. Usually these are mycoplasmas, candida. Adnexitis is subject to compulsory treatment, otherwise acute process goes into chronic form, which serves as a direct path to infertility. The leading symptom of adnexitis is periodically manifested pain in the lower abdomen and in the ovarian region, sometimes radiating to the lower back.

2. If the ovarian appendages become inflamed, this type of inflammation is called oophoritis in the medical environment. Its symptoms are similar to those of adnexitis; in particular, the patient sometimes feels that her ovaries are in severe pain. This sensation is born in the lower abdomen, but can also radiate to the lumbar and sacrum areas. Attacks of pain for the most part occur in waves, but sometimes oophoritis is accompanied by constant pain. With stress, hypothermia or impaired immune processes, pain becomes more frequent and intensifies. The result of these processes is disturbances in the functioning of nervous system: sleep is disturbed, a woman becomes characterized by excessive irritability, weakness and drowsiness, concentration and ability to work decrease.

3. Sometimes pain haunts a woman at the stage of formation and growth of the cystic capsule. As long as the dimensions do not exceed the permissible limits and its structure is not changed or has changed slightly, no symptoms of the disease are observed. If a cyst or other neoplasm grows to a significant size, in almost one hundred percent of cases it is the reason why the ovaries hurt. The reason for this is compression peripheral nerves and nearby organs.

4. It is also possible for an ovarian cyst to twist, which leads to dangerous consequences: due to the impossibility of normal blood flow, inflammation, necrosis may develop, and severe pain may occur in the ovaries. If the leg of the cyst is twisted or its contents spill into the abdominal cavity, the danger extends beyond the usual tissue irritation. This pathology is fraught with the development of peritonitis - inflammation of the peritoneum. The only one effective method combating peritonitis is an emergency surgical intervention. In addition to ovarian torsion, peritonitis can also be caused by tumors, regardless of their type.

5. Excessive doses can stimulate ovarian torsion. physical exercise. Since the ovarian appendages are located freely in the abdominal cavity, it is enough to just overexert yourself a little, and eventually come to pathological change ovarian position. Children often suffer from this disease. In addition, those at risk are people receiving drugs to stimulate ovulation, pregnant women and those suffering from pathological increase ovarian sizes.

Symptoms of ovarian torsion: acute pain in the ovarian area, nausea, vomiting, the ovary is greatly enlarged in size. In case of emergency intervention, the ovary can usually be saved, but if the tissue becomes necrotic, there is a possibility of removal of the appendage.

6. Sometimes during ovulation the ovary bursts, in which case very sharp pain is felt. Rupture is fraught with the development of diffuse peritonitis, which is a common consequence of blood entering the abdominal cavity. Only surgical intervention can stop the process of infection and the development of inflammation. The affected organ is sutured to a complete state.

Note: If you decide to have a barium X-ray, it can help determine whether ovarian cancer has spread to the rectum or colon. The day before the test, the patient should take a laxative. Diagnosis is as follows: a mixture of sulfate and barium is poured into the rectum and colon. These ingredients help make the diagnosis clear.

A chest x-ray is done if you are sure you have ovarian cancer. This method allows to detect the presence of metastases in the lungs.

Positron emission tomography can also reveal the presence of cancerous tumor. With laparoscopy, you can examine not only the ovaries, but also the rest of the pelvic organs. A biopsy is performed as a diagnostic test. It is prescribed if the MC is disturbed, the body has fibroma, accessory lobes, tecomatosis, polycystic disease or papillary growths.

Occurs in everyone's body healthy woman monthly. This period is called. The day the follicle emerges is considered the most favorable for conception child. The ovulatory process can be accompanied by numerous ones with varying degrees of intensity.

Ovarian pain after ovulation

The main cause of pain in the ovary during ovulatory period are natural processes, occurring in a woman’s body. accompanied by rupture of the follicle and further movement to the fallopian tubes. During this process, the woman may feel discomfort.

Nature of pain

The intensity and nature of pain depends on many factors. These include the impact of external negative factors, presence of diseases reproductive organs And general state health. Pain in the ovary can be barely noticeable or, conversely, be severe and change the quality of life. It all depends on the individual characteristics of the body.

Pain in the ovary after ovulation can be felt alternately: either the right ovary hurts, or the left ovary pulls or hurts. Both ovaries They cannot be sick at the same time.

Every month, only one can ripen in a woman’s body (there are rare exceptions to the rule). This occurs either in the right or left ovary.

If other symptoms appear need to see a doctor. Similar conditions may be accompanied by diseases of the reproductive organs.

Pulls the ovary

The nature of the pain may vary. Nagging pain in the ovaries are considered normal. The following symptoms occur under the influence of natural processes happening in female body. , then leaves the follicle and moves to the fallopian tubes. These processes cause discomfort varying degrees intensity.

Colitis ovary

Minor tingling in the ovaries may occur due to individual characteristics woman's body. And sharp spasms most often accompany deviations in the functioning of the reproductive organs. For example, ovarian apoplexy (tissue rupture) first appears as stabbing pains, and then the condition sharply worsens until loss of consciousness. This happens due to hemorrhage in the abdominal cavity.

Ovarian aches

Aching painful sensations can also arise both naturally and due to troubling reasons. If such a symptom is not a characteristic phenomenon for the period, then its appearance may be provoked by adnexitis developing under the influence of infections different types. The aching sensations spread to the lumbar region and may have cyclical nature.

Duration

Period occurs within 1-2 days, respectively, the woman feels pain during a similar period. If discomfort persists for more than long term, then this is a reason to see a doctor. Especially if the pain is accompanied vaginal bleeding, fever or other serious symptoms.

IMPORTANT! If you suspect the development of gynecological diseases, it is necessary to as soon as possible consult a doctor. The specialist who deals with any problems related to women's health is a gynecologist.

Why does the ovary hurt after ovulation?

The main cause of pain in the ovary is follicle rupture and exit. However, in some cases, the intensity of symptoms may increase under the influence of inflammatory processes or gynecological diseases. For example, with a sharp spasm after

Painful sensations in the ovaries are the scourge of young women and a very common problem, which, alas, they do not often rush to the doctor. But monitoring the health of the most important organs of the female reproductive system is the fundamental task of each of them. And if pain appears in this area, then this circumstance should in no case be ignored in order to avoid complications in the sexual sphere in the future. Estet-portal.com. suggests understanding the characteristic symptoms of such pain and the causes of its occurrence.

Why do the ovaries hurt: possible causes of the problem

In fact, pain radiating to the ovarian area may be a consequence of pathologies occurring in other organs located nearby, for example:

acute appendicitis;
disease Bladder or rectum;
formation of adhesions in the pelvis.

If you are worried about pain in the right ovary, then try to normalize the activity of the bladder, as well as the kidneys, since the latter, in particular, are in line with the ovaries. To do this, you can brew anti-inflammatory and disinfecting tea: 1 tbsp. l. Pour boiling water (1.5 cups) over dried sage and chamomile. After a few hours, the decoction is ready for use: drink it within 30 minutes. before meals, 7–8 tbsp. l.

If the left ovary hurts, pay attention to the activity of the intestines: often the cause similar discomfort Processed but stale food may become.

Pain directly in the ovaries can “result” in the side, back, and in the area above the pubis. And there are many reasons for this. In particular, the following are highlighted.

Inflammation of the ovaries and their appendages

It may be caused by hypothermia, chronic stress, exhausting diets, low immunity. In this situation, the pain makes itself known unobtrusively, it is often aching, there may be a disruption in the menstrual cycle, the appetite may worsen, and the woman often becomes especially irritable.

Ovulatory syndrome

It is directly related to cyclical changes inherent in a woman’s body.

So, at different phases of menstruation - before them, during ovulation, during regular periods and after them - pain in the ovaries may occur, and this is the norm.

The culprit discomfort may become an egg released from the follicle, since this process is associated with slight inflammation.

Ovarian cyst

For a long time, such a neoplasm may not make itself felt. However, later, when the inflammation intensifies, the woman begins to experience severe, sharp pain. Discomfort increases during menstruation, since during this period the ovaries are activated.

The rupture of a cyst is of great danger: it can not only destroy the ovaries themselves, but also lead to extensive internal hemorrhage.

Infectious inflammation

This inflammation (otherwise adnexitis) is a consequence of infection with bacteria (mycoplasma, chlamydia) or fungus. It is very dangerous because it can “spread” to the ovarian appendages and fallopian tubes, which can lead to infertility. With adnexitis, a woman experiences such characteristic symptoms as: sharp stabbing pain in the lower abdomen or back, fever, nausea, and disruption of the menstrual cycle.

Hormonal disorders

The condition of the ovaries is directly dependent on hormones thyroid gland, and if its function weakens, this can lead to discomfort in the paired sex glands of a woman. But, since a feature of the ovaries themselves is also the secretion of hormones, pain in them may be a consequence of their “fatigue”, for example, after pregnancy, during breastfeeding or menopause. In the future, the activity of these organs will return to normal, and the pain will go away.

In conclusion, we note: only a doctor can give a definite answer to the question - why the ovaries hurt. Because the reasons why such pain occurs are very diverse. We hope that the information provided will help women quickly navigate the problem and immediately seek help from a specialist.

Painful sensations in the lower abdomen are not a disease. This is a common symptom of many pathologies in the reproductive system of the female body. As a rule, pain in the ovaries signals the need for treatment of a gynecological disease. Let's look at the main causes of this symptom.

Aching pain in the ovaries

Painful pulling sensations occur with ovarian cysts. In this case, only one side “aches”: either the right or the left ovary. If it is difficult for you to determine how much an ovarian cyst hurts and you have doubts, pay attention to how you feel after sexual intercourse. Often after it Bottom part The stomach begins to sip a little. Sometimes a woman feels not so much pain as a feeling of heaviness and discomfort. When the ovaries hurt, they use folk remedies: they are treated with decoctions and infusions of coltsfoot, yellow clover, and wintergreen. But all this must be agreed with the attending physician, because even the use of herbs has its contraindications.

Often this symptom indicates... In this case, echoes of aching character extend to the lower back. As a rule, a woman experiences irregularities in her menstrual cycle, mood swings and all signs of dysfunction of the glands internal secretion. It is generally accepted that the presence of small cysts begins to put pressure on the organs, which is why the ovaries hurt, and treatment in this case should be aimed at restoring function endocrine system(elimination of excess androgen production), weight correction and recovery menstrual cycle.

Painful, aching sensations in the ovaries and perineum are often a symptom of endometriosis. While endometriotic growths are not very large, a woman may not be aware of their occurrence. As soon as the formations reach a certain size, dull aching painful sensations appear in the lower abdomen, in the perineum, and often radiate to the rectum. If the ovaries and perineum hurt, the first thing to do is go for a consultation. The danger is that upon reaching large sizes heteropia, bleeding begins, which may well lead to the formation of an adhesive process.

Sometimes painful sensations in the lower abdomen are echoes of pathologies from other organs. This could be a sign acute appendicitis, adhesive processes in the area of the uterus.

Sharp pain in the ovaries

Severe and paroxysmal pain can occur when the cyst stalk is twisted. Not all cysts are located in the ovarian tissue, some are on their surface. When a rotation occurs around its axis, the leg twists. The woman feels attacks of pain, sharp and unbearable. Sometimes pain is transmitted to the leg and lower back. If the ovaries hurt when the legs are twisted, then treatment comes down to surgery.

If a woman can determine how painful an ovarian cyst is on her own, then its rupture is sometimes not so easy to diagnose. The patient experiences very severe sharp pain, as with many other diagnoses. Signs of urgent hospitalization are sudden pallor skin, decrease blood pressure and loss of consciousness. IN in this case without surgical intervention not enough.

If a woman experiences pallor and decreased blood pressure, but it is sharp pain that dominates, then this may be a signal. A woman may lose consciousness, but this is not a consequence of blood loss, but a reaction to the painful shock of an ovarian rupture. As a rule, the right ovary is more susceptible to apoplexy. The first thing to do if the ovaries hurt badly and the woman has suddenly turned pale, the skin has become dry and the pressure is constantly dropping is to call ambulance.

This is one of the most important organs in the female body. After all, it is in the ovaries that mature eggs are produced, each of which can become the beginning of a new life.

All women have their own individual “reserve” of eggs hidden in the follicles located in the ovaries. On average, their number at puberty ranges from 200 to 400 thousand (for comparison: a newborn girl has about 7 million eggs, but their supply is rapidly decreasing), and they have their own “expiration date.” With age, some of them will be used up, and the rest (if any remain) will completely die after the onset of menopause, and the ovaries will cease to perform a reproductive function.

Starting from puberty in a girl, every month, from one menstrual cycle to another, one of the follicles matures, releasing an egg ready for fertilization. From the remaining cells of this follicle, the corpus luteum is formed, designed to produce hormones necessary for the onset and maintenance of pregnancy. If conception takes place, corpus luteum will function until 10-12 weeks. Then it will “transfer” its functions to the formed placenta and disappear.

The ovaries themselves also undergo Big changes from the moment a woman becomes pregnant. And this is exactly what we will talk about today.

The ovaries are the paired organs of the female reproductive system. They are located in the pelvic cavity near fallopian tubes on both sides of the uterus. In appearance and shape, these organs are similar to nut tonsils, the size of which in the normal state ranges from 1.5-5 cm - this depends on age, and according to the results of some studies, on the reserve supply of eggs.

With the onset of pregnancy, blood circulation in these, as well as in other organs, increases significantly, which contributes to their slight increase in size. In addition, as the uterus grows, the ovaries will increasingly move from their usual place, and soon they will completely go beyond the boundaries of the pelvic ring. It is for this reason that very often, when the ovaries seem to hurt during pregnancy, the source of the pain turns out to be different, because they are no longer in the same place. In pregnant women, these organs move slightly upward and forward, closer to the abdominal wall.

How the ovaries work during pregnancy

It's not just the size and location that change. Since there is no need for ovulation (that is, the maturation of eggs) during pregnancy, the ovaries temporarily “turn off” this function and go into a state of rest.

Their most important task for this period is to produce the corpus luteum, which, as we have already said, functions only in the first weeks of life. early stages.

However, despite this, even now female appendages may make themselves known. And not always in the best way...

If conception occurs against a background of unfavorable conditions in reproductive organs, then it's with high probability will appear during pregnancy. Normally, the ovaries are sterile. But due to various factors, they can penetrate pathogenic bacteria, causing inflammatory processes.

Most often, this happens when infected with sexually transmitted infections (chlamydia, candidiasis, ureaplasmosis, mycoplasmosis, etc.), as well as due to hypothermia in the legs and pelvic area, overwork and stress, decreased immune defense body. So if you are wondering whether the ovaries hurt during pregnancy, then yes, this is possible by various reasons. And most often, such a nuisance happens in the early stages.

Inflammation of the ovaries and their appendages during pregnancy

According to medical statistics, at least 80% of all girls under the age of 25 experience ovarian inflammation. And most of them either do not notice its signs or ignore them. And in vain. This is one of the most common causes of secondary infertility among women. If pregnancy nevertheless occurs, then unhealthy ovaries not only hurt, but can even cause miscarriage and miscarriage. This is why treatment should be mandatory!

An inflammatory process in these organs can be indicated by pain not only in the ovaries, but also in the lower abdomen, as during menstruation, radiating to the lower back and sacrum, which occurs during sexual intercourse and urination. Associated symptoms include increased body temperature, weakness, fast fatiguability, bad dream, nervousness.

Pain (usually occurring periodically, from time to time) accompanies both inflammation of the ovaries (adnexitis) and inflammation of their appendages (oophoritis). And both of these conditions require treatment.

Ovarian cyst during pregnancy

Exists a large number of types of cysts that affect the female reproductive organs, the most harmless during pregnancy is the corpus luteum cyst. The vast majority of them are benign in nature and are prone to spontaneous resorption. However, the cyst increases the risk of ovarian torsion (in addition to torsion of the cyst stalk), and this is no longer safe and can result in its necrosis or rupture with hemorrhage into the abdominal cavity (which is called apoplexy in medicine). Dangerous symptoms requiring immediate hospitalization are nausea and vomiting due to severe pain. Pregnancy itself is also a provoking factor for torsion, since, as we have already mentioned, during this period the ovaries slightly increase in size, which makes them more mobile.

Cyst-like formations on the ovaries are compressed by surrounding organs, causing pain. As a rule, they are palpable only on one side of the abdomen, but are constantly present, in contrast to episodic pain due to inflammation.

In some cases, the fertilized egg is unable to reach the uterine cavity and is forced to land halfway. It is very rare, but it still happens that the fertilized egg is implanted directly in the ovary. This organ, like all others, besides the uterus, is not adapted for the development of an embryo, and therefore such a pregnancy is doomed. Due to growth ovum the ovary begins to stretch and hurts greatly. Most often, the pain is very intense, paroxysmal, radiating to the area anus or thighs, may be accompanied by vomiting, nausea, and loss of consciousness.

If an ectopic pregnancy is not terminated in time, the ovary will rupture, which can lead to intra-abdominal bleeding, infection and other dangerous consequences. Therefore, at the slightest suspicion, it is necessary to undergo an ultrasound, which will determine exactly where the egg has implanted.

What to do if your ovaries hurt, ache or pull during pregnancy

Despite the fact that the ovaries can indeed hurt during pregnancy, and that such pain cannot be ignored, most often a woman’s assumptions turn out to be false. From the first weeks, the uterus begins to increase in size, which entails a number of other changes. In particular, it gradually compresses and expands the organs surrounding it, freeing up the necessary space for itself. In addition, the ligaments located on both sides and holding the uterus are stretched more and more. And it is this pain that, as a rule, women confuse with pain in the ovaries. Therefore, first of all, there is no need to make any guesses. Discomfort due to stretching of the uterine muscles usually occurs from time to time, irregularly, and goes away after resting. comfortable position, deep inhalation and exhalation.

Sometimes such pain occurs due to constipation.

However, the presence of complications is not at all excluded, and you should definitely tell your gynecologist about your complaints. In the meantime, try not to do anything sudden movements and just in case, refuse sex until the reason is found out. It is necessary to consult a doctor urgently if the pain in the ovary (especially on one side) is intense, obsessive, paroxysmal in nature and is accompanied by the following symptoms:

pain in the anus, sacrum, coccyx, lower back, thigh;
sharp pain on one side, while the stomach is tense;
increased body temperature;
nausea, vomiting;
loss of consciousness;
bloody discharge from the vagina.

IN critical situation when the pain seems unbearable, you need to call an ambulance and wait for it to arrive, lying on your side. It is better not to take any painkillers, so as not to “erase” clinical picture. And in general, in this case, you cannot take any action on your own!

The onset of pregnancy entails many changes in a woman’s body. Most of them are associated with the launch of new biochemical processes that are responsible for healthy development fetus One of important changes in the reproductive organs - the corpus luteum during pregnancy. This one is temporary endocrine organ has another name - luteal gland.

Read in this article

What is the corpus luteum?

Many people mistakenly believe that the corpus luteum is a sign of pregnancy. In fact, this additional gland appears every month at the site of a ruptured follicle, from which a full-fledged egg was released. When menstruation occurs, the corpus luteum in the ovary completely stops functioning and dies. The gland received its main name due to its characteristic color, and its second name due to the content of the hormone luteotropin.

If fertilization occurs during ovulation, the luteal gland continues to produce the hormones progesterone and estrogen, which are necessary for the full development of pregnancy. They are released for 13-15 weeks until the fully formed placenta takes over this function. The development of the gland occurs in four successive stages:

After ovulation, the cells of the ruptured follicle begin to multiply intensively.
Germination occurs blood vessels in the tissue of the uterus.
Stage of hormonal activity and growth of the gland.
The phase of reverse development, gradual death and formation of a whitish body (scar).

Dimensions of the corpus luteum

The size of the corpus luteum in early pregnancy will depend on the amount of hormones produced. How larger area glands, the higher the level of hormonal activity. In the second phase of the menstrual cycle, the normal size of the gland is 18-20 mm, which means it is fully ready for fertilization.

20-30 mm is the normal corpus luteum during pregnancy during the first trimester after conception. If such dimensions were found in the absence of pregnancy, it means that a liquid formation, which regresses on its own over time.

A gland larger than 30 mm already indicates the presence of a corpus luteum cyst in the early stages of pregnancy. This is a benign neoplasm that does not harm either the expectant mother or the child. In most cases, it resolves on its own by the middle of the second trimester of pregnancy. If the corpus luteum is bothersome or severely painful in the early stages of pregnancy, you should contact your supervising doctor to prescribe painkillers.

If the luteal gland was not detected as a result of diagnosis, this does not mean that the size of the corpus luteum in the early stages of pregnancy is below normal. It is possible that the research was carried out on outdated equipment that does not have sufficient functionality to represent the real situation.

Diagnostics

When performing an ultrasound of the ovaries, the corpus luteum is specifically examined in the following cases:

monitoring the ovulation process when planning pregnancy;
in the first trimester;
for infertility;
in the diagnosis of cystic corpus luteum.

The specialist must measure the size of the gland, its volume, and density. All indicators are recorded on the expert ultrasound screening form.

Pathology

The main pathology of the luteal gland is hypofunction of the corpus luteum. As noted above, this small endocrine organ produces two types of hormones - progesterone and estrogen.

Thanks to the first muscle tissue covering the spiral arteries of the uterus atrophy. The uterus stops responding with contractions to various factors, chemical and physical changes in the body of a pregnant woman. As a result of these changes, blood flow to the placenta and embryo is maintained for normal level. Estrogen helps the fertilized egg become firmly attached to the inner wall of the uterus. It prepares the uterine epithelium, makes it more loose, reducing the risk of miscarriage in the early stages.

What are the risks of hypofunction of the gland?

With hypofunction of the gland, the process of hormone production is disrupted, as a result of which the body can perceive the fertilized egg as foreign body and begin to reject it. Clinically, this manifests itself as placental insufficiency.

The negative consequences of gland hypofunction are:

rejection of a fertilized egg;
pregnant;
swelling;
increased protein levels in;
premature birth.

To save the fetus, the attending physician prescribes replacement therapy progesterone drugs.

Corpus luteum at ectopic pregnancy produces much less hormones. This can be detected in the early stages after testing for hCG. By tracking growth dynamics, you can calculate the likelihood of the risk of complications.

What to do if the corpus luteum has not formed

Pregnancy without a corpus luteum is also accompanied by hormonal therapy. For the full development of the embryo you will need full course hormone or its plant analogue in dosage form.

Some women complain that their corpus luteum hurts during pregnancy. Unpleasant sensations can occur during heavy physical exertion, as well as during sexual intercourse. In this case, it is recommended to reduce activity, otherwise the cyst may rupture.

To avoid pathologies associated with improper development or the functioning of the corpus luteum, it is recommended to reduce activity and physical activity in the first three months of pregnancy.

A quiet, measured lifestyle will help you bear a healthy, beautiful and, most importantly, long-awaited child!

Corpus luteum of the ovaries: what is it?

The corpus luteum means a special organ of the endocrine system, which is formed for a certain time and has the purpose of preparing the inner mucous membrane of the uterus for the attachment and subsequent development of the fetus. This gland is called yellow because of its characteristic lutein pigment, which has this color. The production of the hormone progesterone is the most main function assigned to this body. In addition, thanks to the corpus luteum, the ovaries also produce hormones such as estrogen, androgen, oxytocin, inhibin, relaxin and others, which are responsible for the preservation and proper development pregnancy.

The corpus luteum measures about 10-27 mm, but varies depending on the phase of the menstrual cycle. In the case of smaller or larger sizes than the norm, we can talk about insufficient functioning of the corpus luteum or its structure.

Formation of the corpus luteum: what's what?

The corpus luteum forms and functions under the control of the ovaries, pituitary gland and immune system. The education process consists of 4 stages:

Proliferation. After the level of luteinizing hormone rises sharply and the egg is released into the abdominal cavity, the walls of the follicle that has burst gather into folds, and hemorrhage occurs in its cavity, and active division of granulosa cells begins. Sometimes formation of the corpus luteum in the ovaries can occur without ovulation - in the case of luteinization of the dominant follicle.
Vascularization. Blood vessels appear in the growing follicle cells, which is extremely important for providing the gland with proper blood circulation and its full functioning. According to researchers, the corpus luteum holds the record among other organs of the female body in terms of blood flow intensity.
"Flourishing" There is a peak in hormonal activity of the corpus luteum; it becomes purple and protrudes above the surface of the ovary. If conception does not occur, the gland remains active for 10-12 days, after which it gradually fades away.
Regression. If pregnancy does not occur, the cells undergo dystrophic changes, decrease in size and gradually turn into white body– a scar zone, which then disappears spontaneously. During the same period, the concentration of sex hormones in the body decreases, the endometrium is rejected and menstruation begins. At the same time, new follicles begin to mature.

If conception has occurred, the corpus luteum is stimulated with hCG - human chorionic gonadotropin human, which is produced by the cells of the fetal membranes until the end of the first trimester of pregnancy, after which all the tasks of the corpus luteum are transferred to the placenta.

Pathological changes in the functioning of the corpus luteum

Insufficiency of the corpus luteum, which is responsible for the production of progesterone, can provoke inability to conceive, fetal death early stages pregnancy or miscarriage. This pathology can be diagnosed only by the results comprehensive examination, consisting of ultrasound, plotting basal temperature body over 2-3 menstrual cycles, tests for the amount of progesterone in the blood. In addition, an endometrial biopsy will be needed.

If the diagnosis is confirmed, the patient is prescribed progesterone-containing hormonal drugs, for example, duphaston or utrozhestan. Also effective is a course of injections of natural progesterone, which can continue even with confirmed pregnancy for up to 12-13 weeks to prevent breakdowns. Also if formation of the corpus luteum in the ovary insufficient, drugs such as dostinex or bromocriptine, etc. may be recommended.

Among the pathologies of the corpus luteum, it is also common functional cyst. It is diagnosed using ultrasound examination. The reason for its occurrence is hormonal imbalance in the female body. The size of cysts of this kind does not exceed 60 mm, but along with their occurrence, a woman may feel heaviness and pain in the lower abdomen, sides and lumbar area.

If a cyst on the corpus luteum is detected during pregnancy, progesterone-containing drugs are prescribed. In addition, it is recommended to reduce physical activity. As pregnancy progresses, the cyst will usually disappear on its own. If a cyst on the corpus luteum occurs in a non-pregnant woman, it will disappear after the next menstruation or over several cycles. Significant danger to women's health and she does not imagine the development of the fetus in the womb, but it is better to keep it under control.

The corpus luteum in the ovary is a temporary gland that is formed in the female body after ovulation and produces a special hormone - progesterone, which promotes pregnancy.

Characteristics of the corpus luteum

What does the corpus luteum mean in the ovary? This endocrine gland originates from the granulosa cells of the ovarian follicle. It is formed at the site where the egg leaves the follicle during the luteal phase of the menstrual cycle. The process of formation of the corpus luteum is controlled by luteinizing hormone, which is synthesized in the anterior lobe of the pituitary gland.

Progesterone is a pregnancy hormone; if it is deficient, conception does not occur.

After ovulation, the corpus luteum forms gradually in the ovary. During the entire menstrual cycle, iron goes through three stages of development:

Proliferation is the stage of gland formation through active cell division. This process normally occurs on days 8-14 of the menstrual cycle.
Vascularization is the process of formation of new capillaries in the corpus luteum, which ensures blood supply to the gland and flow to it nutrients and hormones from higher nerve centers. Vascularization occurs on days 14-16 of the menstrual cycle.
Bloom - phase best development and growth of the corpus luteum. During this period, the gland looks like a thick layer of bright yellow cells with blood clot, which is penetrated by a network of capillaries and is located directly in the middle of the corpus luteum.

If a woman has pain in the ovary, which contains the corpus luteum, then this in most cases indicates the presence of this ovary cysts or other diseases of the appendages.

The hormones of the corpus luteum of the ovary are estrogen and progesterone. Estrogen is produced in small quantity. The function of progesterone is to prepare the uterine mucosa for possible fertilization and egg implantation.

In addition, progesterone inhibits the functioning of a woman’s immune system - since the fetus is a foreign particle for the body, it the immune system would have killed him immediately, even at the stage of reproduction of the first cells.

The presence of the corpus luteum in the ovary prevents the maturation of new follicles in the event of pregnancy, stimulates the growth of the mammary glands, increases the number of blood vessels in the uterus and reduces its sensitivity to stress that occurs when a fertilized egg is implanted into the mucous membrane.

Important! The corpus luteum in the ovary during pregnancy, until the placenta is fully formed, performs its functions - the synthesis of hormones that support pregnancy.

If fertilization does not occur, the gland gradually regresses. It decreases in size and looks like a whitish area of scar-connective tissue that disappears over time.

After regression of the corpus luteum, the process of maturation of a new follicle begins. It is accompanied by the shedding of the uterine lining - menstruation, and the cycle repeats again.

Examination of the corpus luteum

Control over the formation, functioning and regression of this temporary gland is carried out using ultrasound, which is carried out in two ways - transvaginally (through the vagina) and transabdominally (through the abdomen).

It is necessary to examine the corpus luteum in the ovary after ovulation in the following cases:

during pregnancy planning to assess ovulatory function;
with functional infertility;
at the beginning of pregnancy;
if a corpus luteum cyst is suspected;
to control cystic formation of the luteal gland.

The corpus luteum in the ovary on ultrasound looks like a yellow sac located inside the ovary. The structure of the corpus luteum in the ovary is heterogeneous, this is normal. If the luteal gland is absent and there is a delay in menstruation, this indicates pathological processes V reproductive system women, as well as endocrine disorders.

At positive test the absence of the corpus luteum in the ovary indicates a threat of miscarriage. In this case, it is necessary to carry out hormonal replacement therapy with progesterone preparations (Utrozhestan, Duphaston). The drugs are discontinued after the placenta has fully matured and is functioning properly (progesterone and estrogen must be produced in sufficient quantities to maintain the pregnancy).

Important! You should not assume that if you find a corpus luteum in the ovary, this clearly indicates pregnancy. This gland is formed in each cycle and indicates pregnancy only in the absence of regression and delay in menstruation.

The sufficiency of the function of the corpus luteum is judged by its size in different phases menstrual cycle. Thus, the gland size of 18-22 mm in the second half of the menstrual cycle indicates the body’s readiness for conception. During pregnancy normal indicators The size of the gland ranges from 20-30 mm.

In the presence of follicular cyst(when ovulation does not occur) the size reaches 23-30 mm. A size between 30-40 mm indicates a fluid formation in the ovary.

Attention! The corpus luteum in the ovary cannot cause pain. When painful sensations It is necessary to be examined; most likely, the woman will have a cyst in the ovary.

Using ultrasound diagnostics, they also monitor the follicular and luteal cystic formations. The duration of such constant monitoring lasts several cycles. Normally, the cyst should resolve on its own. There are several possible options for the development of cysts:

active cyst growth - requires surgical intervention, using a laparoscope, the cyst is removed;
if there are no changes after three cycles, continue monitoring the tumor.

During the period of observation of the cyst, it is recommended to delay conception. If pregnancy has occurred and a cyst is present, then it is necessary to carry out hormone replacement therapy to maintain normal development fetus You must first take a blood test for progesterone and determine the need to administer an artificial hormone.
