Is the chance of ectopic pregnancy with blastocyst high?

The biggest wish of fathers who are preparing to have children is to give birth to healthy babies smoothly. However, in the process of pregnancy and childbirth, there are many risks, including ectopic pregnancy. There are many manifestations of ectopic pregnancy, such as the implantation of the embryonic sac in the fallopian tube, which is a type of ectopic pregnancy. Ectopic pregnancy is very harmful to women and needs to be treated in the hospital in time. So what is the general probability of blastocyst ectopic pregnancy?

Is the chance of ectopic pregnancy with blastocyst high?

After the blastocyst is successfully transplanted into the uterine cavity, it will float freely in the uterine cavity for a few days, about 3-4 days, before it finds a suitable position in the uterine cavity to implant and then develop. However, if during the process of blastocyst transplantation, it floats into the fallopian tube or the cervix, it will naturally cause an ectopic pregnancy. The risk is about 1.5% to 2%. Therefore, blastocyst transfer may also cause the risk of ectopic pregnancy, so it is best to perform bilateral tubal ligation before transfer, so that the proportion of ectopic pregnancy will be significantly reduced.

For female friends who are actively preparing for pregnancy, they are very afraid of the occurrence of ectopic pregnancy, especially for women who have related physical obstacles and need to become pregnant through blastocyst transplantation. They are even more afraid that the occurrence of ectopic pregnancy will deprive them of the opportunity to become a successful mother. Will blastocyst transplantation lead to ectopic pregnancy? Why is there a risk of ectopic pregnancy? Let’s take a closer look below!

Will blastocyst transplantation lead to ectopic pregnancy?

I believe that many patients with fallopian tube adhesions are very concerned about whether blastocyst transplantation will lead to ectopic pregnancy. However, in fact, the blastocyst transplantation technology itself cannot completely prevent the occurrence of ectopic pregnancy, let alone reduce the chance of ectopic pregnancy. Will blastocyst transplantation lead to ectopic pregnancy? The blastocyst has not yet successfully implanted when it is transplanted, so the blastocyst may move. In fact, patients with problems such as fallopian tube adhesions are more likely to have an ectopic pregnancy after blastocyst transplantation.

Then why is there a risk of ectopic pregnancy when transplanting blastocysts?

First of all, during the transplant process, the embryonic sac is mainly injected into the female's uterine cavity through a transplant tube. The principle is the same as fluid perfusion or fallopian tube patency check. Because the embryonic tissue is still very small when the blastocyst is transplanted, it is possible that the blastocyst will be injected into the fallopian tube during the transplant process, leading to an ectopic pregnancy.

In addition, after the blastocyst is successfully transplanted into the uterine cavity, it will continue to float freely within the uterine cavity. It will take about three to four days to find a suitable implantation site and then develop. However, if the blastocyst floats into the fallopian tube during the migration process, it will naturally cause an ectopic pregnancy. Therefore, there is a lot of uncertainty in blastocyst transplantation, and its success rate is not 100%. It is hoped that women who need blastocyst transplantation can choose a regular professional hospital for the transplantation operation to better improve the success rate.
