The growth of hCG on days after implantation it is necessary to know the doctor to monitor the developing pregnancy. In consequence of the attachment of the ovum to the wall of the reproductive organ of the number of chorionic substance increases. It takes place on the 49 day of new life.
Why implants affect the level of hCG
HCG after implantation changed to 9 hours. Height chorionic substance occurs daily. Scheme increase gonadotropin:
- 1 month - 10 mIU / l;
- 2 hours - from 3 to 18 mIU / l;
- Day 5 - within the 45 mIU / l;
- Day 10 - 400 mIU / L.
The growth of chorionic material begins to 84 days of pregnancy and continues for a month afterwards engraftment of the ovum, it is 19000-78000 mIU / L.
In some cases, the embryo to attach to the shells is not 4, and 12-13 day. From 4 to 12 day low hormone content, if pregnant pass the blood, its value will be 1.2 mIU / L.
The introduction of ovum mucosal reproductive lumen facilitates daily increase chorionic substance which increases twice several days. Its amount is determined in the urine. Analysis confirmed pregnancy.
In the initial period of formation of the placenta after implantation embryo chorionic substance affects the growth and development of the intermediate trophoblast.
The hormone ensures the normal course of pregnancy a woman's reproductive organs that contain fruit.
Urine contains gonadotropin, which is formed after 10 days after fertilization.
As the level increases after implantation
Investigation of urine shows how rising hCG on days of implantation, the table contains information about the number of chorionic substance is produced daily after the release of the mature egg. Studying the result, a physician sees in 1 trimester amount of gonadotropin is reduced. Process changes caused by an external shell fetal embryo.
| Conception term days | At least mIU / l | The maximum mIU / l |
| 7 | 2 | 10 |
| 8 | 3 | 18 |
| 9 | 5 | 21 |
| 10 | 8 | 26 |
| 11 | 11 | 45 |
| 12 | 17 | 65 |
| 13 | 22 | 105 |
| 14-21 | 29 | 3100 |
The decrease of the gonadotropin as a result of implantation of an embryo refers to the physiological process. Due to the attachment of ectopic gestational sac changes hormone parameters. Ovum stays in the fallopian tubes.
During pregnancy outside the reproductive organ is a growth hormone in the same range as after attachment of the ovum in the norm. Subsequently gonadotropin increases slightly, lagging behind the normal value in 21 hours.
Implantation structure surrounding the embryo, often occurs as a result of IVF. The level of hCG changes daily after the procedure. If the age of the embryo is 7 days after replanting day embryo, the minimum amount of gonadotropin expressed in U / ml, of 2 units, and maximal -. 10 mU / ml. From 10 to 20 hours the minimum value gonadotropin - 8 mU / ml, maximal value - 2000 IU / ml.
In late pregnancy, if properly conducted IVF chorionic substance at 42 weeks has a maximum value of 128 200 IU / ml. The observed increase of the hormone by the application of high technology.
Pregnancy after IVF develops in 40% of cases.
Thanks to such methods exclude the possibility of having a baby with genetic disorders, where the risk is increased if a pregnant woman more than 40 years.
The body of pregnant women is different, so the level of gonadotropin after implantation grows differently. Some patients observe the formation of antibodies against hCG. Women spend treatment. The content of antibodies to the hormone after the introduction of fertilized eggs increased in terms of: 5-15, 21-25, 30-33 weeks. Some patients with sensitization to the hormone detected early appearance of DIC, which is the main cause of death of the embryo.
If the index does not grow
The change in the hormone in the urine sample indicates the pathology of pregnancy. Gonadotropin decreases due to fetal death when threats of miscarriage, malformed placenta.
The death of a child is accompanied by a sharp decline in the hormone to 86,077. If a woman is expecting twins, gonadotropin value increases. If the death of one child, gonadotropin levels decrease.
By reducing levels of the hormone in a woman has no chance to save the baby. When in a frozen fruit 1 trimester produced not only low gonadotropin fetal heart rate is also missing.
If the retest sets hormone decline, while non-viable twins doctor does not listen to the heart beat of every fruit. A study conducted in a few days, indicates a further decrease of the hormone, its value reaches 86,077.
fetal loss syndrome occurs in 20% of cases. Often gonadotropin falls to 14 weeks of pregnancy due to lack of progesterone. When genetic pathology hormone value decreases.
The decrease in gonadotropin - a sign of the termination of the fetus. hormone levels in the urine in the first days of 1 trimester reduced.
Dynamics of reduction of human chorionic gonadotropin occurs at an interval of 2-3 days. Its value is 9 times smaller than the normal values ​​established for the duration of pregnancy. After the death of the fetus gonadotropin reduced the number of daily.
