What is the precursor of IVF abortion?

IVF refers to the embryos cultivated in vitro fertilization and embryo culture environment through assisted reproductive technology, and then transferred to the mother's uterus to develop into a healthy baby. However, sometimes IVF babies may face the risk of miscarriage. In order to predict the possible risks in advance and take corresponding measures, it is important to understand the precursors of IVF abortion.

Abnormal embryonic development

One of the precursors of IVF abortion is abnormal embryonic development. In the process of IVF, the quality of embryo development will be affected by many factors. If the development of the embryo is abnormal, such as abnormal cell division speed, insufficient or excessive cell number, and embryo structure problems, abortion may occur. In this case, doctors often observe the development of embryos and carry out necessary treatment.

In fact, some hospitals have adopted new technologies in the process of IVF, such as extreme embryo culture technology, which can improve the success rate of IVF and reduce the risk of abortion. But even if these techniques are adopted, abnormal embryonic development may still occur.

Endometrial abnormalities

The abnormality of endometrium is also one of the precursors of IVF abortion. Endometrium is an important environment for embryo implantation, and its abnormal changes may affect the growth of IVF. Endometrial abnormalities may be manifested as insufficient or excessive thickness, uneven growth, abnormal vascular distribution, etc.

In order to prevent abortion caused by abnormal endometrium, doctors usually carry out relevant examinations before the test tube cycle, such as hysteroscopy or ultrasound, to ensure the health of endometrium. If endometrial abnormalities are found, the doctor will take corresponding measures according to the specific situation, such as drug treatment, surgery or adjusting the test tube cycle plan.

Antiembryonic antibody

Another possible precursor of IVF abortion is the production of anti embryonic antibodies. Anti embryonic antibody is an immune response of human immune system to its own embryonic tissue, which will lead to the abortion of test tube baby. The formation of anti embryonic antibody may be caused by genetic factors, abnormal immune function or threatened abortion.

In order to diagnose the existence of anti embryonic antibodies, doctors will carry out relevant tests, such as testing the antibody titer of anti embryonic antibodies. If the antibody titer is found to be high, doctors will take measures to adjust the test tube cycle, give immunotherapy or choose other assisted reproductive technologies to increase the success rate of test tube babies.

Summary

The precursors of IVF abortion mainly include abnormal embryonic development, endometrial abnormalities and the production of anti embryonic antibodies. The occurrence of these precursors will increase the risk of IVF abortion, but many risks of abortion can be reduced or avoided by early detection and taking corresponding measures. Therefore, it is very important for couples preparing for IVF to understand and prevent the occurrence of these abortion precursors.
