Most couples who try to do IVF have experienced the inner torment of infertility and the huge pressure of childbirth, so the failure of IVF surgery is an unacceptable blow. Transplantation is the most critical step in the IVF process, and in general, successful implantation indicates successful conception, so what are the reasons for transplant failure? Let's follow Hengjian overseas to learn about it together.
1. The physical relationship itself, which is the root cause of implantation failure after IVF transplantation. Due to the physical relationship, such as poor implantation environment, inflammation in the body, etc., these are unfavorable factors against the bed. Therefore, it is very important to maintain good health before implantation.
2 Improper maintenance, after transplantation, everyone pays great attention to the maintenance of the implantation period. For example, dietary supplements, etc. However, at this stage, due to improper maintenance, it is also very likely that the embryo will not be able to implant. Not paying attention to the diet, such as eating cold foods or not avoiding the mouth, can easily affect the environment in which the embryo implants.
In addition, the indoor air is not breathable, the body movement is too large, these are the factors that will affect the implantation. Therefore, during this period, be sure to pay extra attention and use the correct maintenance method.
3, emotional over-tension, this period is many female friends are most prone to emotional tension and changeable period. During this period, everyone should relax their mood and avoid physical disorders caused by nervousness and emotional ups and downs, which is also very unfavorable for embryo implantation.
4. Embryonic factors, embryonic chromosomal abnormalities: advanced age, decreased ovarian function, congenital gamete defects in the population, embryonic chromosomal abnormalities have a high rate, often repeated implant failure factors.
5. Immune factors and abnormal coagulation, it has been found that the immune mechanism of the whole body or endometrium is abnormal, such as abnormal increase in the activity of natural killer cells, or other positive immune antibodies, which may have toxic effects on the embryo, can not protect the embryo from being attacked by the immune system, hindering implantation.
Certain coagulation disorders, such as "anticardiolipin antibody syndrome" or "thrombophilia", can lead to thrombosis in the small blood vessels of the placenta, resulting in insufficient blood supply to the endometrium and a decrease in embryo implantation rates.
The success rate of IVF also has a lot to do with the age of both spouses, and older age is one of the main reasons for success, especially if the woman is over 35 years old, the possibility of transplant failure is a little higher. Therefore, Xiaobian suggests that families who plan to have babies must plan early.
IVF surgery has not been successful, it is recommended that no matter in which link fails, we must first find the cause, find out the problem, and improve the success rate of the next transplant.
