hcg reference value 12 days after frozen embryo transplantation

Many mothers who do IVF have to choose frozen embryo transplantation due to physical reasons when they finally transplant the test tube, and they are often vague about the definition of frozen embryo transplantation, so they pop up in major forums and forums, consult those sisters who have successfully become pregnant, and hope that they can also have a good pregnancy~ So, how much is the hcg standard of transplanting frozen embryos for 12 days worth?

Standard hcg value of frozen embryo transplantation on day 12

When the embryo of a normal pregnancy implants, that is, on the sixth day after ovulation, the sperm and egg combine to begin to produce hCG. About one day later, HCG should be detectable in the peripheral blood; thereafter it will increase every 1.7-2 days, generally doubling; reaching about 100U/L 14 days after ovulation. Generally, 12 days after test tube transplantation is equivalent to 14 days after ovulation, the blood sugar level will reach 100 cells per liter, and it should more than double within 48 hours to be considered normal. It reached its peak in 8 to 10 weeks, and then dropped rapidly to only about 10% of the peak.

Here I want to tell you sisters, the success rate of frozen embryo transplantation is not much different from that of fresh embryo transplantation, and frozen embryos will not cause damage to test tube embryos, nor will they affect the growth and development potential of frozen embryos! Let's take a look at the whole process of frozen embryo transplantation!

1. Advance preparation of the uterine wall.

First of all, whether it is fresh embryo transplantation or frozen embryo transplantation, the endometrial thickness must be appropriate. Therefore, the preparation of the uterine wall and the growth and development of the test tube embryo and the synchronization of the uterine wall are the key criteria for the success of pregnancy after molten embryo transplantation. The main methods of uterine wall preparation are: natural cycle method and hormone replacement method. 1) Natural cycle method: For women with regular menstruation and normal ovulation period, transplantation should be carried out during the ovulation period. Before transplantation, a series of tests such as B-ultrasound examination, blood test for endocrine function, etc. should be done. 2) Hormone replacement method: Women with irregular menstrual cycles and ovulation disorders need to use drugs to promote the growth of the uterine wall. Only after the shape of the endometrium has reached a certain requirement can they regenerate and transplant test tube embryos.

2. Thaw the test tube embryos.

The most important step is to thaw the frozen test tube embryos. If any test tube embryos are damaged during the thawing process, they will be discarded. Therefore, the thawing process has very high requirements on the laboratory operating environment and the experimental physicians. It is recommended to choose a professional and authoritative hospital for IVF. When selecting test tube embryos, the consistency of the blastomeres of the frozen-thawed test tube embryos and the ability of the cells to further disintegrate are the main considerations. When transplanting, try to select test tube embryos with intact blastomeres and those that can be further disintegrated.

3. Transplant test tube embryos.

Then comes the last step - transplantation! On the day of transplantation, 3 test tube embryos will be unfrozen first. If the number of surviving test tube embryos is less than 3, they will be unfrozen again until there are 3 surviving test tube embryos available for transplantation.

4. Injection of corpus luteum copper.

Although frozen embryo transfer can be performed at an appropriate time, since the test tube embryo is not fertilized in the woman's body, the woman's body is not fully synchronized with the test tube embryo, and insufficient lutein copper is produced for the fertilized egg to implant and develop, so artificial intake of lutein copper is required. The injection dosage can be as little as possible compared to fresh test tube transplantation. Most doctors will use 40mg/day of corpus luteum copper injection, but doctors will also adjust the dosage according to the patient's individual condition.

5. Confirm pregnancy.

Generally, if you do not have your period two weeks after the transplant, you can go to the hospital to check whether you are pregnant. After a successful pregnancy, it is necessary to continue taking progesterone to maintain the pregnancy and perform an ultrasound test two weeks later.
