What is hCG or human chorionic gonadotropin?
In the body of a woman, this hormone is activedevelops exclusively during the joyful time of pregnancy. But, of course, there are individual situations where an elevated level of hCG can manifest not only in women waiting for addition, but also in men who develop any cancer in the body or they prescribe drugs containing hCG. If the pregnancy progresses, namely the fetus develops normally, the growth of hCG production every two days will increase, its peak occurs at 7-11 weeks, and then very slowly decreases, remaining practically unchanged during the second half of pregnancy. First, this gonadotropin releases a newly fertilized egg, more precisely its outer membrane (chorion), and subsequently the placenta itself. The growth of hCG can be seen already from the second week of pregnancy. That's why after giving this analysis, doctors can judge about its normal development or lag. At 14-18 weeks, the results of this analysis can signal the development of a certain pathology. By appointing this procedure, the doctor is simply reinsured, so do not panic. By the way, the usual pregnancy tests, which are sold in any pharmacy, are also based on the detection of hCG. Only the method of their work is presented a little differently, namely, on the detection of gonadotropin not through blood, but through urine. If there is a fertilized egg, the concentration of this hormone will be half as low as in the normal state of a woman. Of course, the accuracy of this method of determining pregnancy can not be compared with laboratory tests, but it is still, more often than not, reliable information. If the pregnancy regresses or it does not, the test will not show the coveted two strips, because in the urine there will be no gonadotropin content. Under regressing (frozen) pregnancy means the termination of growth and development of the child. The foundations of this pathology are quite different, but mostly it is anomalies of fetal development. Anomaly of development of the fetus is a set of deviations from the normal structure of the organism that arise during the intrauterine or, more rarely, postpartum development. The physiology of any woman is such that poor-quality genetic material is eliminated by nature itself. This factor explains that a different kind of fetal mutation leads to its death. Still the given pathology can arise, if at the woman immune or hormonal disturbances, development of chronic, infectious diseases are observed. For example, rubella, chicken pox, influenza virus, etc. Stress, smoking, alcohol, exposure to external factors (heat, cold), exercise can also affect the fading of the fetus. If a woman does not develop a pregnancy, that is, the fetus is dead, the amount of hCG in the blood and urine quickly decreases. Determine the level and growth of gonadotropin can be, by submitting a blood test. If the dynamics of hormones is in place or there is a slow increase, then, most likely, it is a sign of an abortion or its threat. But the decrease in hCG is possible with the slow development of the child or if the pregnancy was initially set incorrectly, therefore, ultrasound should be done to fully confirm the diagnosis, where the presence or absence of palpitation is the decisive definition. There have been cases when hCG in the deadened pregnancy is growing, although other signs have already come to naught. Most often the pregnancy stops at the initial stages of development, but the embryo can die and for a long time. In this case, the hCG decreases rather slowly, since its disintegration takes time. So, we found out what hCG is and in what cases the termination of pregnancy is possible. Now let's look at the normal parameters of gonadotropin analysis. Table of hCG growth in pregnant women: Term HCG, mJ / ml 1 - 2 weeks 25 - 156 2 - 3 weeks 101 - 4870 3 - 4 weeks 1110 - 31500 4 - 5 weeks 2560 - 82300 5 - 6 weeks 23100 - 151000 6 - 7 weeks 27300 - 233000 7 - 11 weeks 20900 - 291000 11 - 16 weeks 6140 - 103000 16 - 21 weeks 4720 - 80100 21 - 39 weeks 2700 - 7810 Sometimes it happens that the growth of these hormones is higher than normal, but do not immediately worry, since, perhaps, this is a sign of multiple pregnancy: usually hCG increases in proportion to the number of embryos attached to the wall of the uterus. 
Elevated hCG may indicate the following pathologies
- toxicosis;
- gestosis;
- fetal development anomalies, Down syndrome;
- pregnancy overdelivery.
Or, for example, if a woman is ill with sugardiabetes, takes synthetic gestagens. There is also a special pathology called anembryonia, which is a special case of pregnancy fading, where there is a living fetal egg in the uterus, but there is no embryo in it. And this egg produces live cells of hCG, but the growth of these hormones will not meet the standards. In the presence of this pathology, a woman feels the same way as a pregnant woman, she may have toxicosis, and even the growth of the tummy is possible. But all the same in this case, the exact diagnosis will be made by a doctor, only after passing the ultrasound. In general, it is clear that to treat the analysis of gonadotropin as a plausible conclusion is not necessary, and even more so to put yourself a diagnosis. He is only one of the facts that should be taken into account in the current situation, so let the doctor put the best opinion. So, this article describes what is hCG and frozen pregnancy, signs of fading fetal development. Remember, in order to tolerate a healthy and strong baby or baby, try to lead a healthy lifestyle, and do not forget to eat properly and eat well, go outdoors more often and breathe fresh air. Good luck and all the best!
