What can be compared to the joy that a woman who wears a long-awaited child under her heart? But sometimes the desire to become a mother is marred by long and unsuccessful attempts to get pregnant naturally.
Thanks to the development of medical science, the problem was solved by in vitro fertilization( IVF).The effectiveness of the procedure depends on a large number of factors, it does not give 100% of the result. However, the rapid growth of hCG is evidence of the successful consolidation of embryos after transference.
What is the amount of hCG in the blood?
Once the fertilization of the egg has naturally occurred, the amount of the hormone begins to grow exponentially in days. A similar process occurs after the IVF procedure. The only difference is that its development begins after the successful implantation of the embryos. In both variants, the amount of chorionic gonadotropin allows to determine, with an accuracy to the day, the term, the threat of interruption or the frozen pregnancy. Therefore, it is so important to monitor its content in the blood.
Before implantation, hormonal rates range from 5 to 15 mU / ml. After 5-6 days after the transfer of a certain number of embryos, the hCG index begins to increase gradually. The rapid growth of indicators begins from the second week after the completion of a successful procedure of artificial insemination. Such dynamics are observed up to the 15th week of gestation, then the growth of the hormone slows down a bit, and only lasts from 22 weeks.
Hormonal norms after IVF
The course of pregnancy after embryo transfer is monitored by means of data on the hormone content in the blood. Lack of chorionic gonadotropin may indicate an abnormal development of the child or abortion, but excess is about multiplicity. To determine the success of the operation and the subsequent viability of the fetus, there are norms for the gradual increase in the hormone in the body of a woman for weeks:
| Fetal age( weeks) | Bottom level | norm Boundary level | |
| ( mU / ml) | |||
| 1-2 | 1550 | 2150 | 5500 |
| 4-5 | 9500 | 21000 | 31500 |
| 5-6 | 21000 | 51500 | 115000 |
| 6-7 | 51500 | 115000 | 200500 |
| 7-8 | 21000 | 71000 | 115000 |
| 8-9 | 21000 | 65100 | 115000 |
| 9-10 | 21000 | 61500 | 95500 |
| 10-11 | 21000 | 55000 | 95500 |
| 11-12 | 21000 | 45150 | 91000 |
| 13-14 | 15150 | 35150 | 61500 |
| 15-25 | 9500 | 22100 | 35100 |
| 26-37 | 9500 | 28150 | 61500 |
Statistical data on the growth of the hormone may not coincide with the actual values, A small error may not be indicative of the existenceserious deviations in the development of the fetus after IVF.The table is only an approximate reference point, on which doctors rely to track the process of bearing a child.
Chorionic gonadotropin growth table by days
For the most accurate determination of the correctness of fetal development after completion of the embryo transfer procedure, doctors recommend that patients after the IVF procedure perform an analysis that checks the level of the chorionic gonadotropin by days. The frequency of delivery of such an analysis can be from 2 to 3 days , this is due to the difficulty of attaching artificially planted embryos. The table of limit values of hCG by days allows to determine how systematically the development of the fetus proceeds under artificial insemination:
| Fetal age( days) | Bottom level | Norm | Boundary level |
| ( mU / mL) | |||
| 7 | 2 | 4 | 10 |
| 8 | 3 | 7 | 15 |
| 9 | 5 | 11 | 20 |
| 10 | 8 | 18 | 25 |

Table of hCG values for double
The procedure of artificial insemination involves the implantation of several embryos, in order to engraft at least one. Therefore, often the consequence of the transfer of embryos becomes a multiple pregnancy. Identify the pregnancy of twins allows a test for the content of hCG.Table of indicators of its weekly growth, with twin pregnancies:
| The gestation period of twins( weeks) | Norm( mU / ml) |
| 1-2 | 25-156 |
| 3 | 100-4900 |
| 4 | 1110-31500 |
| 5 | 2600-82000 |
| 6 | 23000-150000 |
| 7 | 27000-230000 |
| 8-11 | 20900-290000 |
Thanks to the tables containing the limits of the content of HCG, it is determined not only the success of the IVF procedure, but also the further development of pregnancy. The content of chorionic gonadotropin in a woman's blood can signal in a timely manner about placental insufficiency or genetic abnormalities of the fetus. And early diagnosis, as you know, allows you to take the necessary measures in a timely manner. Therefore, for all women who underwent in vitro fertilization, it is important to periodically take tests for hormone levels.
