Features of the dynamics of growth of gonadotropin and the reasons for its low concentration
The concentration of human chorionic gonadotropin in the normal development of the fetus continuously increases from conception to 7-11 weeks of gestation, increasing by several orders of magnitude. Then the hormone level begins to slowly fall.
This dynamic is explained by the biological role of hCG: the active production of this substance supports the functioning of the corpus luteum - a temporary gland that produces progesterone and, in the absence of a fetus, exists only for two weeks of the cycle. Under the influence of gonadotropin, the ovarian follicular apparatus also produces an increased amount of estrogen and weak androgens. The corpus luteum is actively functioning until the placenta is able to independently produce estrogen and progesterone in the amount that will ensure the normal development of the fetus.
However, after losing the need for a yellow body, chorionic gonadotropin continues to be produced in large quantities, albeit smaller than at the peak corresponding to 7-11 weeks of gestation.
The embryonic hormone adapts the future mother's body to a stressful state, which is a hormonal failure, and suppresses the immune response to foreign tissue by stimulating the production of corticosteroids (in the absence of adrenal hormones, half of the other genetic set would provoke the rejection of the embryo). An important role is played by gonadotropin in maintaining the functionality of the placenta itself, primarily by stimulating blood flow in its tissues.
If the concentration of a hormone that is so important for the normal course of pregnancy is low, then this may indicate the following pathologies:
- hormonal disruptions in the body of the expectant mother, a high probability of spontaneous interruption of gestation,
- deviations in the development and growth rate of the fetus (including missed abortion) - in this case, the mother may reject the fetus,
- fetal fetal death (at 14-40 weeks of gestation),
- chronic placental insufficiency,
- implantation of the egg outside the uterus.
Such violations can not only prevent successfully carrying out the child, but also create a danger to the life of a woman.
What is ectopic pregnancy
Ectopic pregnancy (BM) is a pathology in which a fertilized egg attaches and begins its development not on the wall of the uterus, but in the fallopian tube, the wall of the ovary, the cervix, and in extremely rare cases even the liver. In 98% of cases, the ectopic location of the embryo is tubal.
VM is extremely dangerous to the health and life of the patient at once for several reasons:
- It can flow very similarly to the normal one; however, at an unpredictable moment it ends with a rupture of the tube in which the embryo was implanted.
- At the time of the bursting of the pipe by the growing fetus, the woman receives a strong painful shock. Internal bleeding occurs, which can result in the death of the patient in the absence of medical care and surgery.
- After surgery with the removal of the pipe, the probability of bearing children in the future is significantly reduced.
There is no chance of preserving the fetus in such a pathology; therefore, indicators of hCG in ectopic pregnancy that differ from the norm have important diagnostic value. They allow laparoscopic surgery to remove only the ovum, which significantly reduces the risk of infertility and eliminates the likelihood of patient death from internal bleeding.
According to statistics, every 50th pregnancy is an ectopic, so early diagnosis, including monitoring the growth of gonadotropin and ultrasound of the pelvic area - a common practice in gynecology and obstetrics.
Hcg level during weekly pregnancy
Accurate diagnosis of chorionic hormone levels is one of the most important aspects of monitoring pregnancy. This is largely due to the simplicity of the test: the pathology can be suspected even with only a series of qualitative tests that determine the presence of hCG in the patient's urine. However, a blood test for the concentration of chorionic gonadotropin is considered more accurate.
Growth dynamics of hCG in ectopic pregnancy differs markedly from normal: if at the location of the ovum in the uterus, the hormone content increases by 60–100% approximately every 1.5–2 days, then the pathological location is manifested by a rarer increase in the concentration of gonadotropin - on average two times in Week.

Analysis of hCG in ectopic pregnancy in the early stages
The embryo cannot develop outside the uterus and is doomed to death. In this case, the woman herself is in grave danger.
If internal bleeding appears and medical assistance is not provided in time, the failed mother can die. To avoid this, you can diagnose pregnancy. This can be done by analyzing the level of hCG.
Ectopic pregnancy: definition
Ectopic (or ectopic) pregnancy is a gynecological anomaly that occurs frequently. After conception, the egg must move into the uterine cavity, where everything is intended for its further growth. If this does not happen, the embryo remains outside - in the tube.
Unfortunately, a child cannot be saved in this situation, but for the mother this situation is fraught with dangerous consequences. The ovum grows by division, and after a couple of weeks it will no longer fit into the tube of the uterus. Gradually stretching, the tissues of the tube will tear, and internal bleeding will begin. If time does not provide medical care to a woman, she may die.
HCG during normal pregnancy
HCG (or CG) is a human chorionic gonadotropin, that is, a hormone produced in early pregnancy. Its concentration will increase dramatically by 7 weeks after fertilization, and then the indicator begins to gradually decrease. This is because the hormones begin to be produced by the placenta itself, and not by the embryonic membrane, as it was before.
If the embryo is outside the uterus of a woman, the concentration of the hormone in the blood will be below normal. The sooner doctors find a pathology, the less female health will be at risk.
What does hCG show?
The hormone CG is produced by the chorionic tissue (the outer membrane of the fetus) after the successful implantation of the embryo into the uterus. This happens around the first weeks after fertilization of the egg.
The hormone contains α (alpha) and β (beta) particles. The latter are unique and have a special composition, which sharply distinguishes them from other human hormones. It is with the help of β-particles that analyzes are performed, indicating the presence and development of pregnancy.
The test is done independently at home, but not earlier than 2 weeks after the onset of the delay in menstruation. For this you need to buy strips for the definition of pregnancy in the nearest pharmacy.
In the laboratory about the occurrence of a happy event can be found within a week after conceiving a child. Blood CG contains twice as much as in urine. Such analyzes will, of course, have greater reliability than test strips.
Does hCG show an ectopic pregnancy in the early stages?
Determination of the location of the fetus outside the uterus is possible only with the help of analyzes.
When receiving the results of the study, the doctor compares them with the normative.
So pathology is excluded. If the embryo is in the fallopian tube, the hormone CG does not enter the blood in the right quantity.
Consider the whole algorithm of actions of the doctor to establish the exact medical conclusion:
- Blood test for hCG. It all starts with him. Accurate data using this study can be obtained within 4 days after conception. Pregnant women do it in the morning on an empty stomach. Blood is taken from a vein. Ectopic pregnancy gives lower rates than normal. If a deviation from the norm is found, then do a second test after a couple of days.
- Urinalysis for hCG levels. It is handed over, as a rule, simultaneously with the previous research. As stated above, the level of the hormone in the urine is slightly lower than in the blood. On the eve of surrender urine can not drink more than 2 liters of water.
- Ultrasound. Poor results of previous analyzes are the reason for the passage of ultrasound. Delay here is unacceptable, since the health of the woman is under threat. In the early stages, the human embryo in the uterus is sometimes hard to see, but in the tube it is clearly visible on the first days of conception.
After passing all these tests, the doctor makes a diagnosis. Since the fetus cannot survive during ectopic pregnancy, it is interrupted.
How to determine the analysis of ectopic pregnancy in the early stages?
You can perform the analysis at home by buying test strips. Do not use them, if after the beginning of the delay of the month did not pass 7-10 days. This analysis will have an accuracy of 90%.
If one of the strips is weak (pale), then this may indirectly indicate the presence of ectopic pregnancy. Laboratory blood tests provide more accurate results.
Low hormone levels
The hCG value, which is below normal, is evidence of ectopic embryo attachment. In addition, low numbers can talk about fetal death or placental insufficiency.
Fearing ahead of time is not worth it, because low rates sometimes also indicate an incorrect calculation of the date of conception. As stated above, a diagnosis is not made on the basis of a blood test, so a pregnant woman needs to undergo additional studies.
Table by day
The doctor decrypts the results of the blood test for HCG using a table that shows the standard indicators of the concentration of the hormone on a particular day of pregnancy.
If there are no deviations, then there is no need to worry, since the development of the fetus occurs normally.
If the results are underestimated, then it is worth undergoing additional research to clarify the situation. Low rates do not always indicate violations. For example, in non-pregnant women, the hormone hCG is also present in the blood, its value here is 0–5 mU / ml.
Below is a table that reflects the standards of hCG in the blood of the days after ovulation.
