What is the success rate of fresh embryo transfer?

Infertility situations are very complicated. Some infertility problems cannot be cured and the chances of successful conception are very low. When it is impossible to get pregnant through normal means, some people will choose fresh embryo transplantation to help them conceive. When they learn about this method, they are definitely concerned about the chances of success. So, what is the success rate of fresh embryo transplantation? Let’s take a look below.

The success rate of fresh embryo transfer is around 30%. Generally, before test tube transplantation, the egg and sperm will be combined in vitro to develop into a fertilized egg and then cultured into a blastocyst. The blastocyst is cultured in vitro for 5-7 days. When the dominant blastocyst is formed, it is transplanted into the uterine cavity, where it continues to implant, grow and develop. Generally, the success rate of fresh blastocyst transfer is around 30%. The success rate of fresh embryo transfer depends on the high quality of the blastocyst on the one hand, and on whether the environment of the female uterine cavity is suitable for the growth and development of the blastocyst on the other. Therefore, before women undergo test tube transplantation, they must adjust their bodies to the best condition to be suitable for conception.

How many days can the fresh embryo be tested after IVF transplantation?

In fact, we have introduced to you earlier "how many days does it take for IVF to implant after transplantation". In fact, whether it is fresh embryo or frozen embryo transplantation, their implantation time is almost the same. For fresh embryos, it may take 3-5 days to implant and 6-8 days to take root. Some people with better physical conditions may implant in 3-4 days, and those with poor physical conditions may not be detected even 10 days after transplantation. This is normal.

Because the time of implantation is roughly the same, the time when fresh embryos can be detected in test tubes is also the same, generally around 6-8 days. Of course, the results of early pregnancy test strips during this period are for reference only. The specific and accurate results must be obtained by measuring the HCG value 14 days after transplantation.

If no result is detected within 10 days after the IVF embryo transfer, it is best not to be too anxious. It may be that the test time is too early. You can test again after another week. The result will be more accurate. Or you can go to the hospital for a B-ultrasound examination, which will help to check the result.

Signs of successful fresh embryo transfer

1. First of all, the signs of successful fresh embryo transfer are very obvious. Often women will have some early pregnancy reactions after implantation. Generally, about ten days after IVF transfer, pregnancy can be effectively detected by using early pregnancy test paper.

2. Based on the successful experience of fresh embryo transfer shared by most women, some symptoms can be known, such as feeling tired, frequent urination or tender breasts, and nausea and vomiting;

3. Bleeding after embryo transplantation sometimes also indicates the success rate of implantation. The amount of bleeding at this time will not be much. If the amount of bleeding is large or the bleeding time is long, female friends should go to the hospital to find out the cause.
