The hCG values after embryo transfer are determined only after two weeks from the procedure itself. This analysis gives a chance to assess the level of the hormone in the blood of a patient of the IVF clinic, which is increased due to the presence of the embryo in its genital organ.
In order to detect this hormone, the level of hCG after embryo transfer is required to reach a specific value. It is calculated in specially designated units, such as mEAD per 1 ml of blood plasma. If the data obtained were lower than 5 mU / ml, then the pregnancy did not occur. And such an analysis result as 25 mU / ml and more is usually considered a joyous omen.
However, one must realize that the obtained positive value of hCG after embryo transfer is not at all the only true sign of a successfully experienced artificial insemination procedure. Doctors strongly recommend supplementing this analysis with ultrasound diagnostics. This method is needed not only to specify the presence of an attached egg, but also to observe the process of its development. Also, ultrasound will help in a timely manner to concretize ectopic pregnancy and fertilization with several fruits.
How is hCG growth after embryo transfer?
In obstetrical practice, there is a special table of hCG after embryo transfer, which contains the most approximated to the ideal concentration of this hormone in the blood of a successfully fertilized and nonpregnant woman. It helps physicians and the patients of the IVF clinics to understand the results of their research.
In almost 85% of fertilized women, the degree of the hormone of the chorionic gonadotropin is increased a couple of times, and this occurs every 48-72 hours. However, this process can be somewhat slowed down, which is explained by the peculiarities of the organism and does not at all mean that the bearing does not progress or there is some complication.
The first month of the hCG norm after the transfer of embryos is extremely fast, and in a positive way. However, after 6-7 weeks after the procedure, the growth hormone data ceases to grow at this rate, and the increment is a doubling of the initial value in 3-4 days. After 9 to 10 weeks, the degree of concentration of the chorionic gonadotropin is reduced.
If the pregnancy has not occurred then, respectively, the hCG value is below the norm. The woman marks the onset of menstruation a few days after the transfer process.
