IVF technology has been widely accepted by the public in the historical development process. More and more infertile patients are pinning their fertility hopes on IVF technology. During the assisted pregnancy process of IVF

, it is necessary to go through steps such as promotion of expulsion, egg retrieval, transplantation and pregnancy testing, and gradually advance before it is expected that expectant mothers will successfully conceive the baby. So, in the face of repeated failed implantation of test-tube babies, we

How should I respond? What factors affect the success of IVF?

For women who repeatedly fail in vitro transplantation or abort after successful transplantation, it is recommended to go to a regular hospital first to find out the reasons for unsuccessful transplantation and find out the causes of repeated failures.

Then take the right countermeasures for treatment. Be sure to keep in mind that you should not seek medical treatment in an urgent situation, and try so-called Jianghu folk prescriptions at will, otherwise it may have adverse effects on IVF-assisted pregnancy.

Repeated failures of tube transplantation may be the result of a combination of factors, including embryo quality, endometrial environment or autoimmune function.

1. Embryonic factors

The quality of embryos is an important factor in determining the success or failure of tube transfer. Clinical studies have shown that the better the quality of embryos, the higher the rate of tube implantation. Today, the third generation of IVF technology has been able to transform

Embryos are cultured until the blastocyst stage and then transferred. After the cultured blastocyst is transferred, the probability of success will be greatly increased.

2. Endometrial receptivity factors

The receptivity of the endometrium means that the endometrium allows the embryo to adhere, invade and induce a series of changes in the endometrial interstitium, which in turn enables the embryo to gain the ability to implant. Currently, more than two-thirds of the population

The failure of tube transplantation is due to insufficient receptivity of the endometrium. Factors such as the thickness, lesions, intimal and subintimal blood flow, hydrosalpinx and other factors will affect the receptivity of the endometrium.

3. Reason for immunization

In vitro transfer of embryos is a semi-homologous transfer that mainly relies on the regulatory functions of the immune system. Regulatory T cells in the mother inhibit immune excretion to the mother caused by half alloantigen

Repulsion reactions play an important role in maintaining immune tolerance during the embryo transfer stage and subsequent pregnancy.

4. Psychological factors

Patients undergoing IVF must have a lot of inner pressure. It should be noted that inner anxiety and depression can interfere with the success of tube transplantation.

Although the emergence of assisted reproductive technology has made mankind take an important step in solving the problem of infertility. However, the problem of tube transplantation failure is sometimes unavoidable. For in vitro assisted pregnancy

For families, they must still have full confidence in themselves and believe that they have been fully prepared for this IVF assisted pregnancy.
